Who Is Transparent Labs?

If you’ve been searching for the best protein powder, you’ve no doubt heard of Transparent Labs.

Sites, users, and reviewers all seem to rave about this company.

It’s almost as though the company popped out from no where and appeared at the very top of everyone’s list.

It’s almost sketchy, right?

Well you’re right to be suspicious.

This company has a fantastic affiliate program.

But one thing you need to be impressed with is that they don’t distribute their products anywhere but their own site.

Their own site is the only place where you can get their supplements.

Amazon,, Walmart, GNC, not even Ebay.

Transparent Labs can only be found at Transparent Labs.

The good thing is that you don’t have to worry about it being contaminated, expired, etc, or anything as the site is the only seller of it and you’d be the first to hear about any issues like that.

So what exactly is this protein powder that we’re going to talk about?

It’s Transparent Labs Grass-Fed Isolate protein.

It sounds like something only vegans would rave about but believe us, if you want the most “anabolic” source of protein, it needs to be from natural and grass-fed cows.

And this protein is sourced from small farms based in America. 

ProteinSeries Grass-Fed Protein

Let’s be honest.

When you first heard “grass-fed” all you could think about is some hippies running a free-roam farm where cows can go wherever they want, and eat the healthiest and natural sources of food.

And you’re probably sitting there with a bit of skepticism, as we once were.

This is what Transparent Labs write about their grass fed protein:

“Made from naturally-fed, hormone-free cow and clean of artificial sweeteners, food dyes, gluten, and preservatives”.

So what?

It’s one of the cleanest protein in the market.

Most people don’t care much about how their food was treated before it was slaughtered for food, but there’s more to it than just having a source of clean protein.

Grass fed cows have a ton more benefits for your own health.

They not only have a higher source of omega 3 fatty acids (by 5 times!) but their protein also have a higher source of minerals and the fatty acid ratio is better when compared to grain-fed cows.

Who's It For?

By now you probably have a bit of interest in what getting some Grass-Fed protein from TL.

As with all protein powders, this is a supplement that should assist you with your diet.

There are a few reasons and benefits why you’d want to take a protein isolate like…

Lower calories / high protein
Quick source of protein
Quicker digestion of protein (post workout recovery)
Milk allergies / intolerance of lactose
And to top it off, this naturally flavored whey isolate is one of the best tasting ones.

It doesn’t matter what your fitness level is, if you’re a man or woman, this protein isolate is made for everyone.

Bodybuilders who are looking to take the natural route of diet and supplements will probably enjoy this.

The whole line up of supplements from transparent Labs, from pre workouts to bulk powders are naturally flavored and have an edge in advantage when it comes to buying their products in bulk.

What To Use TL Grass Fed Isolate With?

If you’ve ever made a smoothie or a protein shake, then you’d know all kinds of good stuff that goes well with protein powders.

Grass Fed Isolate is no different.

Depending on the flavor you get, you can use various recipes for shakes and smoothies that will go well with this protein powder.

What Goals Does This Support?

Since Grass Fed Isolate has no fat or carbs, it works well if you’re trying to lose weight.

It is low in calories, uses natural flavoring, and tastes amazing.

Protein powders using stevia or natural flavoring are usually ok or just bareable enough to tolerate.

However with Grass Fed Isolate, naturally flavored protein powder doesn’t taste better than this.

This also works well if you’re bulking or maintaining since it’s quite versatile and can be used with any kind of diet.

It is basically pure protein without the fats or calories.

Best Time To Use Grass Fed Isolate

Whey isolate is super fast with digestion.

Since it doesn’t have anything to slow it down, it is best used post-workout.

If you’re mixing this in a smoothie or shake, you can add in sources of fat to slow down the digestion but that would increase the calories which is something to watch out for if you’re trying to lose weight.

How Does Locally Sourced Protein Sound to You?

It’s hard finding protein powder that is made from grass fed cows, let alone from small clean farms.

Most farms in the States are using grain-fed cows and contain far more health risks that are not worth it.

This is 100% percent pure grass fed protein.

It doesn't get cleaner than this.

Transparent Labs Protein

The various choices of protein from TLabs lets you have the choice between isolate, concentrate, mass gainer and even vegan protein and collagen hydrolysate.

Isolate, concentrate and the mass gainer are all made from grass-fed cows. 

The difference between isolate and concentrate is the processing methods.

Isolate is much more filtered for protein, so you’ll get less carbs and fats while keeping protein as high as possible.

Concentrate has all of it’s protein content but it comes with carbs and fats.

If you’re a “hardgainer” then you’ll want to get something healthy with high calories, and TLabs serves that with their ProteinSeries.

While the mass gainer has the most amount of calories and macros, concentrate and isolate allow flexibility as you can make your own mass gainer.

TL 100% Grass Fed Whey Isolate Ingredients

Straight out of sustainable, American-owned farms, ProteinSeries Whey Isolate is made out of 100% grass-fed cows.

This means you’ll be getting the highest quality protein with the best possible profile of omega 3’s, fats, proteins and vitamins.

One bottle of whey isolate contains 88% protein so you’re getting 28 grams of protein per 32 gram scoop.

“Made from naturally fed, hormone-free cow whey and clean of artificial sweeteners, food dyes, gluten, and preservatives” – Transparent Labs

This stevia sweetened protein isolate is one of the cleanest choices available on the market today.


While we’ve touched on why you should choose grass-fed protein, we can not stop preaching about it.

Most farms treat cows in an inhumane manner, live in dirty and crowded conditions and are usually pumped with hormones and steroids.

Protein made from these cows are going to be unclean, possibly spiked with contaminants and have higher risks for general health in the long run.

Grass-fed cows are given the best possible living conditions, have plenty of space and are much more “natural”.

They have higher and improved fatty acid content, high CLA content (great for fat burning and vitamins.

At the end of the day, Grass-Fed cows are here to stay for the future and nothing will change that so Whey Isolate from TLabs is future-proof.


Any whey isolate should have a high amount of protein per scoop. If you’re only getting 28 grams of protein per 40 gram serving, then you’d know something is wrong.

Fortunately, Transparent Labs Whey Isolate contains one of the highest protein-by-weight ratios we’ve seen with 28 grams of protein per 32 gram serving.

Here are the marcos:

  • 120 Calories
  • 28g Protein
  • 0g Fats
  • 2g Carbs 

Other Ingredients

  • 0mg Cholesterol
  • 134mg Calcium
  • 140mg Sodium
  • 500mg-1g Natural Flavoring
  • 200mg Stevia

Noticed how the transparency continues with the non-active ingredients, in the other ingredients?

The other ingredients are never disclosed with all supplements, but Transparent Labs is the only company (besides NutraBio) that discloses every single ingredient with no exceptions for the other ingredients.

This is the level of transparency that has won this company the reputation that it has today.

We noticed they’ve decreased the cholesterol content from 5.5mg to 0, sodium went from 220mg to 90mg and they’ve increased the carb content to 1g.

This goes to show that Transparent Labs is listening to their customers feedback and improves where they needed to.

Although the 1g carb content is not what anyone wants to see, it is better than having high cholesterol and sodium content.

They’ve even improved their calcium content from 2% to 10% of daily value requirements.


Like the ingredients they’ve improved on, the flavors have gone from chocolate and vanilla to 6 different and diverse flavors.

They still have chocolate but they’ve added in 5 exotic flavors, from french vanilla to cinnamon pastry.

For a protein powder that depends on natural flavoring, this must’ve been very challenging to accomplish as most protein powders with these flavors use massive amounts of artificial flavors and sweeteners.

Here are the current flavors:

    • Cereal Splash
    • Chocolate
    • Salted Caramel
    • French Vanilla
    • Strawberry
    • Mocha
    • Cinnamon Pastry
