Pre Lab Pro Pre Workout Review

Updated July 13, 2023

Pre Lab Pro is a vegan-friendly pre-workout supplement claimed to support your training and fitness goals.

It's a product of Opti-Nutra, a UK-based company known for its cleanly-formulated, vegan-friendly supplements.

Pre Lab Pro is their latest addition, and it's getting popular due to more and more reviewers talking about it.

Let's dig into the label and see if it's scientifically properly dosed...

Pre Lab Pro at a Glance

Pre Lab Pro is a vegan-friendly pre-workout supplement.

It's decently clean and is a low-caffeine pre-workout to support your workouts.

It's a decent companion for your gym sessions, but if you want something with more caffeine and more of a well rounded-formula, we recommend checking out the pre-workouts with 200mg of caffeine or the ones with 300mg.

Key Points about Pre Lab Pro

Before we dive into the details, let's highlight the key points to remember:

  • Pre Lab Pro is packed with vital nutrients, but certain ingredients may not be in sufficient quantities to provide their intended benefits.
  • It's a premium supplement with a higher price tag. However, bulk purchases can offer better value for money.
  • The supplement has a sweet, berry flavor, which might not appeal to everyone.
  • Pre Lab Pro is a vegan-friendly, artificial filler-free product backed by scientific research.

Claimed Benefits of Pre Lab Pro

Pre Lab Pro claims the benefits below; of course, they can be true, but if the dosages aren't high enough for some ingredients, it may not have the claimed benefits.

  1. Smooth Energy and Intense Focus: Pre Lab Pro® is designed to provide smooth energy and intense focus during workouts. This is achieved through natural caffeine and L-Theanine, which enhance cognitive performance and alertness.
  2. No Crash or Gym Jitters: The supplement provides energy without the common side effects of pre-workout supplements, such as jitters or energy crashes. This is likely due to the moderate dose of caffeine and the presence of L-Theanine, which has been shown to mitigate the negative effects of caffeine.
  3. Enhanced Muscle Power and Extended Endurance: Pre Lab Pro® claims to enhance muscle power and extend endurance, allowing you to go harder for longer and recover quicker. This could be attributed to beetroot powder, which has been shown to improve muscle efficiency and endurance.
  4. Refreshingly Clean: The product is free from artificial ingredients and has a clean label. This aligns with research showing that natural ingredients can be as effective as synthetic ones without the potential side effects.
  5. Supports Hydration and Electrolytes: Pre Lab Pro® contains Himalayan pink salt, which provides trace minerals and electrolytes for workout-boosting hydration and homeostasis recovery.

Pre Lab Pro Ingredients

Pre Lab Pro contains a clear label that has some useful ingredients for performance, but some of them are underdosed.

Still, this is a decent choice if you want something clean, safe, and vegan-friendly.

Natural Caffeine (from Coffea Robusta Seeds) (80mg)

Caffeine is a staple ingredient in pre-workout supplements due to its well-documented benefits in sports nutrition.

Pre-Lab Pro contains 80 milligrams of caffeine derived from genuine coffee beans.

This natural caffeine can enhance physical strength and endurance, although the dosage in Pre Lab Pro may not be sufficient for a significant strength increase.

Because of it's low caffeine dosage, it's made our 100mg caffeine pre-workouts list.

L-Theanine (60mg)

L-theanine, a naturally occurring amino acid found in tea and other natural sources, promotes a relaxed state without inducing drowsiness.

Combined with caffeine, it can lead to mild cognitive-enhancing effects, potentially counteracting the "caffeine crash."

L-Tyrosine (400mg)

L-Tyrosine, a naturally produced amino acid, can help prevent cognitive decline under stressful conditions.

It aids in producing adrenaline and dopamine, potentially improving mental clarity, reducing fatigue perception, and providing extra endurance during stressful activities like exercising.

One of the key benefits of L-Tyrosine is its potential impact on exercise performance.

According to a study, exercise can increase the expression of Tyrosine Hydroxylase, an enzyme crucial for producing dopamine, a neurotransmitter that plays a vital role in mood, motivation, and reward.

This suggests that L-Tyrosine might help enhance your mood and motivation during a workout.

L-Citrulline (2.2g)

L-Citrulline, a non-essential amino acid, can increase muscle, reduce fatigue, and improve endurance in aerobic and anaerobic exercises.

However, Pre Lab Pro's dosage might be lower to provide these benefits effectively.

A study found that Citrulline might help improve endurance exercise performance.

It seems that Citrulline could help reduce muscle soreness and improve recovery time after a workout.

So, if you're hitting the gym or the track, Citrulline might be your new best friend.

But that's not all. Another study found that Citrulline could also have a positive effect on antioxidant markers after high-intensity interval exercise. Antioxidants can help protect our cells from damage, so having more of them around after a workout could be good.

Red Beet Powder (1.5g)

Red beet powder, derived from beets, is rich in valuable vitamins, minerals, and antioxidants. It's a beneficial addition to any pre-workout supplement.

Vitamins & Minerals

Pre Lab Pro also includes a variety of vitamins and minerals essential for overall well-being.

While not all directly impact exercise performance, they contribute significantly to your health.

These include Vitamin D, Riboflavin (Vitamin B2), Vitamin B6, Folate (Vitamin B-9), Vitamin B12, Potassium, and Iron.

Analyzing Pre Lab Pro's Price Point

Pre Lab Pro falls into the category of premium pre-workout supplements, which means it's not the most affordable option.

A single canister, providing 20 servings, costs $59, which equates to $2.95 per serving. Bulk Pre-Workout, a better alternative, can decrease the price to $2.21 per serving.

Who's it for

Pre Lab Pro is for anyone looking to step up their game in the gym.

Whether you're a seasoned athlete or a fitness newbie, this pre-workout supplement can help you push harder, train longer, and recover faster.

It's also a great choice for vegans, as it's 100% vegan-friendly.

Who's it not for

Pre-Lab Pro might not be the best choice for those sensitive to caffeine, as it contains a dose equivalent to a regular cup of coffee.

It's also not recommended for pregnant or nursing women or anyone under 18.

As always, it's best to consult with a healthcare professional before starting any new supplement regimen.

Pre Lab Pro vs Bucked Up

Bucked Up is another popular pre-workout supplement on the market. It contains a higher caffeine dose and citrulline than Pre Lab Pro.

However, it underdoses some ingredients like AlphaSize and taurine.

It includes questionable ingredients like deer antler velvet extract that serve no purpose in a pre-workout nor has any science behind it.

Pre Lab Pro vs Pre Kaged

Pre Kaged is a better choice for performance, with more ingredients like citrulline and taurine.

However, it's not the best choice when it comes to pre-workouts.

Pre Lab Pro, on the other hand, offers a cleaner formula with a sensible dose of caffeine and a good blend of vitamins and minerals.

Pre Lab Pro vs. Transparent Labs Bulk

Transparent Labs Bulk is a well-rounded pre-workout supplement with more energy and pumps.

It's naturally flavored and better than Pre Lab Pro in terms of ingredient quantity.

However, Pre Lab Pro's vegan-friendly formula and clean ingredients stand out.
