Protein powders are the worst.

They have beginners believing they can take a serving of protein and make all the gains they can imagine.

Of course protein is essential.

But supplements are often used as a primary source when it should be supplemented with a proper diet.

Supplements are almost always misunderstood in general.

Protein is needed as it's benefical for repairing muscle tissue, help with hormone production and more.

Protein powders are a big section of supplements.

In fact, since 2016, it's far exceeded $3 billion in sales.

With a whole bunch of top 10 lists out there, this has to be one of the best ones you'll find.

The reason being is that we found protein powders that do not use any sketchy practices like amino acid spiking to inflate protein content.


Best Protein Powders for 2021

​​Transparent Labs – the name says it all about this company and their commitment to open labeling and premium quality is never more clear than it is with ProteinSeries 100% Grass Fed Whey Protein Isolate.

They have set the standards high for creating nutritional supplements with high quality ingredients. 

While this is a bit more expensive than your average protein powder, grass fed whey comes at a higher cost, which is understandable since it costs more to produce this type of powder. 

If you compare this to their whey concentrate, this is a much cleaner product with less than 1 gram of sugar, 1 gram of carbs and zero fat.

Whey isolate has a higher protein content (90%) than concentrate without the fat or carbs. 

This is the protein powder to get if you're losing weight and cutting.

They even disclose the flavoring and sweeteners so you know exactly what you're getting..

Transparent Labs has been in the business for years and they've created quite a reputation for themselves with their level of transparency and quality.

But now, you're probably asking, how does it taste?

It tastes great but keep in mind, it has basic and natural flavorings.

It's ideal as it's better to have the bare minimum.

As far as value, you’re getting 30 servings for a premium price, so again, you get what you pay for.

All in all, Transparent Labs ProteinSeries 100% Grass Fed Whey Protein Isolate is one of the best choices, for anyone following the Paleo diet or looking for something that is simply protein without the carbs or fat.

It's one of the lowest calorie protein powders we've found.

Rich Piana left us in 2017 but his legacy lives on through his brand and reputation. 

The legend created 5% Nutrition back in 2014 and there are still new products being released by this company. 

Shake Time is a protein powder made for those who put 110% effort into their athletic lifestyle. 

While you could easily get a cheaper protein powder, Shake Time is made out of real food sources like beef protein isolate, chicken protein and whole egg protein. 

It’s a protein powder designed to live to the standards of Rich Piana, as 5% Nutrition once said. 

Each serving contains only 130 carbs, 2g fat and 2g carbs.

The reason why the extra macros are low is because the beef protein is 96% protein by weight. 

It’s also a patented form of beef, called HydroBEEF, which is made by Essentia Protein Solutions, based in Sweden. 

Beef protein isolate has high amounts of glycine and proline, two ingredients that can enhance joints. 

Shake Time has better bioavailability for protein than real food sources like steak. 

The rest of the formula contains extras like salt, sucralose, MCT’s and natural / artificial flavors.

If you’ve seen our recommendations before, then you’ll know Black Magic Supply is a worthy protein powder made with premium sources of ingredients. 

The protein sources range from whey concentrate to micellar casein, whey isolate and egg protein. 

Mixing up the proteins from fast to slow is excellent for maximum efficiency, since your body will make use of the protein for hours at a time. 

The main highlight of this protein powder is the flavoring system, it’s incredible. 

Few protein powders taste this good and BMS has perfected the taste of this powder. 

Every scoop has 24g protein, 4g carb, and 1.5g fat, making it low fat and a bit high on the carb side. 

Multi-Source is one of the best we’ve had, treat yourself to an amazing tasting protein powder.

Seeing this here shouldn’t come to a surprise. 

RedCon1 has turned their legendary Meal Replacement powder into an affordable protein powder. 

MRE Lite uses only food-based protein sources, from the beef isolate, to protein made from salmon, chicken, eggs, brown rice and pea. 

Seeing how sport supplements are required to label sources from greatest to least, it’s safe to assume beef isolate and salmon are the biggest protein sources here. 

Beef is full of amino acids and it’s 96% protein by weight, which is why it has 2g of fat. 

And it would look like this profile would leave a bad taste in the mouth, literally, but it surprisingly taste amazing 

The flavors are amazing and they actually taste like the real deal. The flavors include apple pie, German chocolate cake, oatmeal chocolate chip, blueberry cobbler, snickerdoodle, and more.

RedCon1 has gone above and beyond with MRE Lite because the profile is what you would expect from a protein powder that uses real food sources and the flavors are exotic and excellent. 

There must be a downside as you’re probably asking now. 

There is and that’s the cost but it costs a little under $2 per serving, and luckily, you can get it at a lower price with our coupon code FITFREK.

Since MRE Lite only contains beef, salmon and chicken protein, it is expensive to produce, making it a decent meal replacement that costs a bit more than your typical protein powder.



You've probably seen this on a number of sites as a recommendation.

Optimum Nutrition has made quite a reputation for being one of the best choices. 

The reason for that is because it contains super high quality protein sources, including whey isolate which is listed first in the ingredient list.

Fat and carb content is low compared to other protein supplements, with only 3g carbs (1g sugar) and 1g fat, it's a healthy choice to use even if you are cutting. 

It mixes easily and we can't find any downsides with Optimum, they even have a good track record with third party testing.

Optimum Whey is one of the most popular and long time selling whey protein powders, so there's almost always deals on this supplement.

Whether it be clearances, BOGO's or whatever else you can imagine. 

It's also one of few protein powders that is lower in carbs and fats.

Every scoop has 24 grams of protein, 120 calories, 1 gram of fat (.5g of saturated fat) 3 grams of carbs (1g of sugar).

And  as any protein powder should, it has naturally occurring BCAA's (5.5g) and it also has 4 grams of glutamine to help with recovery and muscle growth.

So if you've got your multivitamins and creatine, then all you need is a protein powder like this one.



NutraBio has been delivered the highest standards in supplements since 1996.

They are one of the few companies that formulated supplements with full disclosure, including disclosing the “other” ingredients like flavoring and sweeteners, they don't use any sort of prop blends.

Both protein supplements, Whey Isolate and Classic Whey are good choices.

Isolate has different flavoring options that are unique, like breakfast flavors.

These protein powders do not cause any bloating or gas issues that are commonly found in other supplements.

NutraBio is an excellent choice for their protein powders and all of their supplements follow the same high standards. 



ISO-100 is not only a low carb protein powder but is also very low in fat (half a gram per serving).

Dymatize's protein is affordable, so if you're on a budget but still need a whey protein isolate that is trusted and owned by a solid company, then ISO-100 is for you. ​

While Dymatize is not known for their other products, their protein powders are out of this world with flavoring and nutritional value.

ISO-100 uses hydrolyzed whey protein isolate for the fastest absorbing and lists whey protein isolate as the 2nd source. ​

It is mainly sweetened with natural flavors so it isn't as reliant on artificial flavoring as other supplements would be. ​

Most people seem to enjoy these flavors: Gourmet Berry, Pina Colada and vanilla.

ISO-100 keeps the flavor strong by relying mostly on stevia. 



Best known for their C4 pre-workout, Cellucor has been making decent supplements for years.

They are not a brand that has switched to full disclosure labeling, seemingly content to be one of the more established brands still using prop blends in many of their formulas.

They don’t shy away from artificial ingredients either, even in their best formulas.

So it is with Cor Performance Whey.

The label is fully disclosed bt nowhere near full transparency with no breakdowns given for the “Whey Protein Matrix” of whey isolate and whey concentrate.

There’s 2 grams of sugar, 4 grams of total carbs and 1.5 grams of fat – fairly standard.

Cellucor does use artificial flavoring and sweeteners, so as you can see, there’s nothing that makes this product really stand out – but did we mention the flavors?

The one area this product really steps it up is flavoring – you’ve got the usuals, but you also have peanut butter marshmallow, chocolate chip cookie dough and cinnamon swirl – and yes, they do taste really good!

As far as value, you’ll get 70 servings in a 5 pounder at an average price, so it’s a solid value.

So, overall this is a decent product that only tries to be good, it’s not the best and it knows it.



The Genius Brand is a huge seller on Amazon with a excellent reputation for quality and unique formulas, including their cognitive formulas.

Genius Protein is no exception, in fact, it’s an exceptional formula.

There’s a lot that separates Genius Protein from other proteins – first of all, it’s a simple but effective 50-50 blend of whey isolate and micellar casein for fast and slow digestion.

There’s none of this 6 or more proteins, you simply get the best form of fast digesting whey and the best form of slow digesting casein with 24 grams of protein per serving.

The next thing that sets Genius apart is the complete breakdown of each protein – nothing new but it’s still something we only see from a very few companies.

One possible drawback is that there’s 2.5 grams of sugar, but at least they give you the gram total of the cane sugar (2 grams) in this product.

Despite the sugar content, there is stevia.

Really, the best Natural powders use zero sugar, naturally sourced or not, and go with stevia 100%.

It’s only 2.5 grams but it adds up over the course of several shakes and some users will find this unacceptable.

Fat content is virtually nothing and total carbs are 3.5 grams.

Is this product a good value?

Well, pretty much.

It comes in one size only – 2 pounds – with 30 servings and an average price for Amazon.

This is an excellent product overall, even if we’d rather see stevia instead of sugar, but they have a good name for themselves for a reason – they have the quality to back the name up



Protein Powders Buying Guide

Protein powders are not the solution to gains. 

Supplements are just that, supplements.

Whether you're looking to use these to make shakes or ​you're looking for convenience, real food will always be the best option for full optimum health and results. 

What You'll Learn

So what exactly is protein? 

Whether from protein powders or food, it's the same thing. 

After water, protein is primarily what your body is made of.

In fact, about 75% of the dry weight of your body consists of protein.

Your muscles are literally made of protein and your body requires enough protein everyday to perform hundreds (if not thousands) of bodily functions.

If there aren’t enough for your organs to benefit from, your muscles will start to deteriorate or turn into fat.

This is one of the main reason bodybuilders, athletes and fitness-minded individuals need more protein than the average Joe.

It’s vital for their growth.

You’ve no doubt heard of amino acids, there are over 20 of them and they are known as “the building blocks of protein”.

Most of these can be produced by the body, but 9 are considered essential, meaning the body cannot make them.

They must come from your diet and supplements.

These include the super-anabolic BCAAs which directly impact muscle growth.

What Are Protein Powders?

​You have to make sure your body has enough protein to meet the body’s daily requirements – but you also have to have enough protein to meet the requirements of muscle growth.

Remember, if your fundamental needs aren’t met, your body looks for protein elsewhere – meaning your muscles.

One of the simplest ways to help meet your recommended daily intake of protein is to use protein powders.

This is, simply, protein in the form of powder that you can make into a shake or smoothie.

You can use any beverage you like, you can mix it into your oatmeal in the morning and you can even use many powders to bake with – for example, protein pancakes, cookies or muffins.

There are many different choices using various protein sources of varying quality, making it tough to know which ones are the best.

Who Should Take Protein Powders?

Anybody can use protein powders, there are no restrictions, albeit allergy-related cases.

Even if you are allergic to one type, chances are you won’t be allergic to another.

It’s important to understand that your first choice of protein should always be quality whole food options, but that being said, many of us lead very busy lives and don’t always have time to sit down and eat as often as you should if you’re a bodybuilder or athlete – but most likely you can drink a quick shake.

A good protein powder is a cornerstone supplement and should be the first supplement choice for every single beginner.

In this case, it should be the first supplement every bodybuilder, athlete and fitness enthusiast buys.

How Much Protein Should You Consume?

This is the question that has hounded bodybuilding and sports nutrition for decades.

Everybody has an opinion about protein consumption, and the “official” viewpoints tend to change about every 10 years or so.

Back in the late 80’s, for example, it was 1 gram per 2.2 lbs of bodyweight.

Then it became 1 gram per pound of bodyweight, then that number went up to 1.5 grams.

Currently, depending on your source, it’s .7 grams per pound up to 1 gram per pound.

Here’s the thing, if you don’t take in enough protein, those calories will have to come from either carbs or fat or both – of the three, protein is least likely to be converted to body fat, and a little extra isn’t really a problem, so 1 gram per pound of bodyweight is our suggestion.

​What Types Of Protein Are There?

When it comes to protein powders, there are almost never ending types, or sources, of protein.

Way back in the 50’s when the first protein powders were being used by bodybuilders, soy was a common source.

By the 60’s quality had improved to milk and egg sources, and it should be noted that egg white protein was considered the highest quality protein available for decades.

Not much happened until whey protein hit the market in the 90’s, it was and still is considered the highest quality protein you can buy.

Today, besides whey, we have many choices, so let’s take a look at each kind, starting first with standard, non-vegetarian proteins.

First, let’s define a term we will be using – the Biological Value, or BV, of a protein is an indicator of the quality of the protein.

It is a measure of a protein's ability to be used by the body or, the percentage of the absorbed protein that your body actually uses.

The other key term we need to look at is digestion speed.

Different proteins digest at different speeds, making one type more useful than other types for specific situations, such as after a workout, when you need a fast digesting protein, or before bed, when a slower digesting protein is best.

Whey Protein

Whey protein makes up about 20% of milk protein and has the highest biological value (BV) of any protein source.

For example, milk protein has a BV of 91, while egg protein, long considered the best, has a BV of 100.

However, whey concentrate protein powder has a BV of 104, with whey isolate going as high as 159! (1​).

Of course, it’s not as simple as just “whey protein”, there are several types:

Whey Protein Concentrate (WPC)

Whey protein concentrate is the lowest-quality and cheapest form of whey and has a protein content by weight of anywhere between 35 and 80%, with the remaining content consisting of carbs and fats (2​).

When you buy a whey concentrate protein powder, you’ll find it’s thicker and better-tasting than other types of whey.

As far as the rate of digestion, WPC digests in just under 2 hours – whey in general is the fastest digesting protein (2​) and the best choice for post workout use or first thing in the morning after a long 8-10 hours without food.

You have to be careful in your choice of whey protein powder from concentrate, because often the label doesn’t tell you the content of protein you’re getting, in this case you may be buying a product that’s considerable under 80% protein.

And it also contains much more than just protein as it has lactose (milk sugar), other types of carbs, and fats.

Besides quality, the primary drawback of WPC is that anyone that has a hard time digesting dairy products will definitely suffer, we’re talking bloating and gastric discomfort.

There’s no need to worry, the best is yet to come!

Whey Protein Isolate (WPI)

Whey Protein Isolate is the highest quality, purest source of protein you can buy, whey or otherwise.

In the manufacturing process, all carbs (lactose) and fats from the concentrate powder are removed and a typical WPI is at least 90% protein (3​).

Even though whey protein in general comes from milk, if you have any difficulties with lactose, this is the whey protein for you.

Whey isolate contains the ideal combination of amino acids in the perfect concentrations for maximum benefit.

As far as rate of digestion, WPI takes about 2 ½ hours to digest and is more expensive than WPC.

Whey Protein Hydrolysate

Whey protein hydrolysates are the newest type of whey protein as well as the fastest digesting.

This type of whey has been artificially “predigested” or hydrolyzed.

The idea behind it is that an ultra-fast whey means better results, and in fact whey hydrolysate does digest at a lighting fast 1 ½ hours.

However, it’s also more expensive to manufacture, which means that you have to decide if the extra digestion speed is worth the extra cost.

This type of protein is a good choice if you have digestion problems and need an advantage to help you digest your protein easier.

Otherwise, for many users whey isolate, or a whey blend consisting of all 3 types of whey are the best choices.

Casein Protein

Next we have casein protein, and of course there’s more than one type.

Casein is a slower digesting protein, in fact casein can take over 6 hours to digest, depending on the type.

This brings up an important question: which type of protein is the best choice based on digestion speed?

Casein, for example, is perfect just before bed because it can offset catabolism for hours.

It’s also a great choice at the start of a long busy day at school or work when you aren’t sure when you can eat again.

On the other hand, whey digests much faster as we have seen, making it perfect at specific times of the day.

So what’s the answer?


That’s right, many dedicated bodybuilders and athletes either use both kinds separately or use a product that blends proteins for the ultimate in fast and slower digestion.

Think about it, you get the best of all worlds with a protein blend – fast digesting whey for morning and post workout, and slower digesting proteins for your long day or at night.

What could be better?

OK, casein protein is milk protein, in fact milk protein consists of 20% whey and 80% casein.

There 3 types of casein protein:

Calcium Caseinate

​This is the lowest quality casein protein but often is the first choice for many casein protein powders.

Typically, casein is an insoluble compound, and you may find your casein protein doesn’t mix as well as whey proteins.

Caseinates consist of calcium, potassium and sodium and typically undergo a special manufacturing process to improve solubility.

Micellar Casein

This is the purest form of casein protein available.

It’s digested much easier by the body and mixes much better than cheaper forms of casein.

Micellar casein takes over 6 hours to digest, it does this by becoming a gel-like substance in the small intestine which is then slowly released over time, constantly feeding your muscles.

Milk Protein

Milk protein isolate consists of 80% casein and 20% whey, making this a popular choice because it has both slow and fast digestion rates.

Milk protein isolates have a high content of amino acids and are easily digested, making them a good choice for other types of protein supplements, such as protein bars.

Beef Protein

Beef protein powder has never really taken the market by storm despite numerous attempts over the years.

You might think beef should be an excellent protein source, after all, it’s a complete protein that’s high in amino acids plus it’s a natural source of the proven muscle builder creatine (4​).

So why isn’t beef protein a popular choice?

Most beef proteins are made from collagen, which is a poor quality protein source.

The next time you see a beef protein powder or bar, read the label and look for “hydrolyzed gelatin”.

It is commonly used in Jello, just read up the ingredients on those boxes, it refers gelatin this way: “Not a significant source of protein”.

This is a FDA-mandated statement that must be used by manufacturers due to the poor quality of gelatin (5​).

The bottom line is that beef is not the ideal protein source you would think, and our best advice is to stick with other, more proven sources of protein.

Egg Protein

​For years, egg protein powders were the highest quality protein on the market with a BV of 100, good, but not quite as good as whey.

As far as digestion speed, egg protein is considered a medium digesting protein, taking about 4 hours to digest.

The only real drawback with egg protein powders is that they don’t mix well and smell worse.

However, they make a great addition to a protein blend of whey and casein because now you have fast, medium and slow digesting proteins.

Vegetarian Protein Powders

One of the fastest growing supplement sub-categories are plant based protein powders.

All of sudden, everybody has their own vegan-friendly protein powder, which are designed for vegetarians that do not eat dairy products, vegans who avoid all animal products, and fitness minded people with allergies that make a plant based protein the best choice.

Vegetarian protein powders have a thick texture with a chalky taste depending on the brand, and they contain a mix of plant proteins which creates a complete protein (contains all the amino acids) of good quality.

Here are the most common choices:

Vegetarian protein powders have a thick texture with a chalky taste depending on the brand, and they contain a mix of plant proteins which creates a complete protein (contains all the amino acids) of good quality.

Here are the most common choices:

Rice Protein

Rice protein is a high quality protein that contains all of the essential amino acids, which are the ones that cannot be made by the body.

Some research has indicated rice protein can be as effective as whey protein (6).

Still, most plant based proteins combine rice with other sources.

Most plant proteins are a medium digesting protein, taking a few hours to completely digest.

Pea Protein

This is another very common source of protein and often combined with rice protein in many of the plant powders that are seemingly flooding the market.

Like rice protein, pea protein compares well to whey protein (7) and digests as slowly as casein, giving you two great benefits in one protein source.

If there’s a downside, it’s the smell and taste, which is another reason it’s combined with other plant proteins.

Hemp Protein

Hemp seeds is another plant protein that contains all nine essential amino acids along with Omega 3 and 6 essential fatty acids.

However, a drawback of hemp protein is that it’s low in leucine, lysine and tryptophan.

Leucine is one of the BCAAs and an essential amino acid that’s known as the most anabolic of any amino acid due to its direct stimulation of protein synthesis.

Additionally, it does not digest very well – compare the protein digestibility rating (PDCAAS) of hemp (48) to egg protein (100) and whey (104), and you have a protein that isn’t very bioavailable and does not do a good job stimulating protein synthesis (8).

That’s a deal breaker for us!

Soy Protein

Several decades ago, if you wanted a vegan protein source, soy was pretty much it.

Soy protein hit a low spot when it was thought to increase estrogen levels, the female hormone.

However, newer research indicates it is a high-quality protein that contains all of the essential amino acids.

Still, soy does not have the popularity it once had and many vegan protein powders advertise “soy free” on their labels.

Beef Vs Whey

Despite the increased popularity of plant-based protein powders on the market, for most bodybuilders, athletes and fitness-minded users, dairy based proteins still offer the highest quality and best taste.

If lactose is not a problem, you can literally choose any whey or casein protein powder either separately or in a combination of the two.

Of course, you’ll ultimately want a high quality product with a good macronutrient profile and our guide can help you with that.

Lactose Sensitivity

​On the other hand, if you have issues with lactose, such as a little bloating and gas, it can be said that you are “lactose sensitive”.

In this case, a whey or milk isolate is a good choice because all the lactose and fats are removed as part of the filtration process.

Many proteins also contain lactase, which is an enzyme that breaks down lactose.

An additional option in this case is to buy separate digestive enzyme tablets that feature lactase, or even lactase drops that you add to your shake.

The point is, even if you have mild problems with lactose, there are solutions.

Whey isolates are the best choice, but there may be some higher quality casein proteins you could use.

Lactose Intolerance

If you have more severe issues with lactose, you may be “lactose intolerant” and your choices would be limited to only the cleanest, highest quality whey isolates.

Severe Lactose Intolerance

If lactose is out of the question no matter what you do, then dairy based proteins are not an option – that means you’ll have to go with a plant based protein.

Finding one you enjoy the taste of will be a challenge, but the good news is, you have several options to try.

All Natural Options

If lactose is not really a primary concern, but the cleanest possible is, then you’ll want a product with no artificial additives and you have some great choices available, as many brands feature all-natural proteins in their line-up.

The bottom line is that no matter how picky you are, more than likely you can find a dairy based protein that will fit your needs.

How To Buy A Whey Isolate

If you have looked your options over and decided to buy a whey isolate, what do you need to know to make the best choice?

First of all, the best whey isolates, such as NutraBio 100% Whey Protein Isolate, are exceptionally pure with very low in carbs and fat, thanks to the filtration process, leaving an ultra-clean formula.

What's The Protein Content?

Check the protein content by weight.

Divide the grams of protein on the label by the scoop size.

For example, we’ll go with 30 grams of protein with a 34 gram scoop, which gives us 88% protein by weight.

This is a common number for even the best whey isolates, so you know you’re getting a premium product.

The general rule of thumb here is at least 85%.

What can affect this number?


A simple flavor such as good old vanilla does not impact the protein content that much, but more exotic flavors, such as chocolate, will have more impact.

Thickeners And Artificial Ingredients

If you prefer a thicker shake, you’ll want a protein with thickening agents such as guar gum. This is a natural thickener, as compared to xanthan gum, which is not and will affect the purity of the product. The same is true with artificial flavors and sweeteners – even our best choices have them. If you want the cleanest protein possible, you’ll want one with nothing artificial added, which means it will be sweetened with stevia or a blend of stevia and monk fruit.

There was a time when anything with stevia meant a bitter taste, but that does not seem to be the case anymore as companies figure out how to get rid of the bitterness.

Check Cholesterol

​One of the biggest red flags of protein quality is the cholesterol content.

Of course, check the macronutrient profile, check the additives, check the sodium (not everybody does) – but don’t forget to look at the cholesterol.

It should be low because most of it should have been taken out during manufacturing.

For example, if you look at the label of NutraBio’s 100% Whey Isolate, you will see that it has less than 5 mg cholesterol.

Some have even less.

Hint: when analyzing a protein, take the time to see if they have their products third party tested, like NutraBio does.

This verifies the label information and integrity of the company.

So, remember, don’t forget to check the cholesterol content!

As a guideline, a high-quality quality protein source should be:

  • Whey concentrate should be 80 mg or lower​
  • Whey isolate should be 20 mg or lower for average quality
  • ​Whey isolate of premium quality should 10 mg or less

More About Cholesterol:

Cholesterol doesn't seem to be well understood by many people, so it’s important to understand what it is.

First, what is cholesterol?

It can be defined as follows:

Cholesterol is the most common type of steroid in the body.

Cholesterol has a reputation for being associated with an increased risk for heart and blood vessel disease.

However, cholesterol is essential to the formation of bile acids, vitamin D, progesterone, estrogens (estradiol, estrone, estriol), androgens (androsterone, testosterone), mineralocorticoid hormones (aldosterone, corticosterone), and glucocorticoid hormones (cortisol).

Cholesterol is also necessary to the normal permeability and function of the membranes that surround cells.

A diet high in saturated fats tends to increase blood cholesterol levels, whereas a diet high in unsaturated fats tends to lower blood cholesterol levels.

Although some cholesterol is obtained from the diet, most cholesterol is made in the liver and other tissues” (9​).

Despite some benefits, namely its role in the formation of testosterone, cholesterol is not something we want a lot of in our diet, because cholesterol from your diet can be absorbed in the intestines and contribute to your total cholesterol levels.

What Problems Are Associated With High Levels Of Cholesterol?

As you may already know, high levels of cholesterol can increase the risk of atherosclerosis, or blocked arteries due to the buildup of cholesterol on the arterial walls.

This is a problem because it means decreased blood flow, increased blood pressure, and potentially serious heart problems.

There are additional problems caused by high cholesterol: poor blood flow can lead to erectile dysfunction, decreased blood flow to the brain and to the spine.

An adequate blood flow is needed for these areas because it delivers much needed oxygen and nutrients.

If you are concerned about high cholesterol, you can add more fiber to your diet and reduce your intake of long chain saturated fats, hydrogenated oils, and foods that contain high amounts of cholesterol (such as poor quality protein powders).

It’s important to remember, however, that above all else, you should always consult with your doctor.
