Natural BCAAs™ w/ Beta-Alanine

Natural BCAAs™ combines pharmaceutical grade BCAAs with Beta-Alanine to support optimal physical performance.

Research suggests that BCAAs and Beta-Alanine can work together to improve muscular endurance, prevent fatigue, and promote regenerative growth.


  • Preserve lean muscle mass 
  • Maximize strength output
  • Stimulate muscle growth
  • Train harder/longer 

    Proteins, the building blocks of our muscles and the basis of all of the vital enzymes in our body, are made up of various sub-units known as amino acids. Branched Chain Amino Acids (BCAAs) are the most prevalent. They make up 35% of all muscle mass and must be present for molecular growth and development to take place.

    Natural BCAAs


    Increase Strength and Build Muscle

    Branched Chain Amino Acids (BCAAs) and growth stimulating compounds (immunoglobulins, lactoferrin, and serum albumin) boost protein synthesis and provide the building blocks for efficient lean muscle development. Additionally, collagen helps improve creatine uptake and utilization, further promoting increases in strength.

    Recover Fast and Repair Damaged Tissue

    To ensure the fastest recovery possible, each ingredient has low molecular weight for instant nutrient delivery and utilization. A complete profile of Essential Amino Acids (EAAs) are readily available to build new tissue and help with cellular repair that takes place when muscles are recovering from exercise.

    Proteins, the building blocks of our muscles and the basis of all of the vital enzymes in our body, are made up of various sub-units known as amino acids. Branched Chain Amino Acids (BCAAs) are the most prevalent. They make up 35% of all muscle mass and must be present for molecular growth and development to take place.

    During exercise BCAAs are metabolized directly in the skeletal muscle, a process that provides crucial musculoskeletal fortification when you need it most. BCAAs have the ability to increase protein synthesis, making it much easier for your body to naturally build and maintain muscle mass.

    When dieting BCAAs are a useful tool to maintain muscular systems while supporting fat loss. They provide the essential nutrients to preserve lean muscle and prevent breakdown.

    Shockingly, most BCAA supplements on the market today are made from inferior sources (either human hair, hog hair, or bird feathers). Human hair is often used because it’s cheaper and can still be classified as vegetarian. Natural BCAAs™ are made from 100% natural botanical sources. The raw ingredients are purified and milled seven times into a very fine instantized powder. Premium sourcing and the meticulous production process allow for maximum bio-availability, quick absorption, and faster results.

    Natural BCAAs™ contains an additional amino acid called Beta-Alanine. It’s been shown to enhance muscular endurance and reduce fatigue. Beta Alanine naturally increases levels carnosine, which acts as an acid buffer in the body. Carnosine helps protect against diet-induced drops in pH (which might occur in ketosis) and prevent lactic acid from accumulating too quickly in skeletal muscle (which occurs during training). The combination of BCAAs and Beta-Alanine enables you to excel during even the most strenuous workouts.

    Natural BCAAs™ is designed to support optimal physical performance during intense exercise, while following a dieting program, or while simply trying to maintain a healthy lifestyle.

    Suggested Use: Take 1-3 servings per day with water, or as directed by a healthcare practitioner.

    Natural BCAAs™ can be used before/during/after workouts to boost physical performance, or anytime to preserve muscle, accelerate recovery, and boost energy.

    L-Leucine is the one amino acid with the greatest impact on protein synthesis. It helps grow, protect, and heal both muscles and bones. Although certain foods do contain L-Leucine, this essential amino acid in it’s free form is absorbed much quicker.


    L-Isoleucine promotes glucose uptake during exercise and helps provide cellular energy. During training it’s used as fuel by muscle cells, sparing other amino acids from being burned up and preventing loss of muscle mass.


    L-Valine promotes nitrogen balance which is essential for muscular growth. It can also stimulate the central nervous system and assist in regulating blood sugar levels.


    Beta-Alanine naturally increases levels of carnosine which helps reduce lactic acid build-up. It has been shown to enhance muscular endurance, prevent fatigue, and improve physical performance.

    Branched Chain Amino Acids (BCAAs)

    A 2012 study examining the effects of resistance exercise and BCAAs, individually and in combination, found that  “BCAA has an anabolic (muscle growth) effect on human skeletal muscle, an effect that appears to be similar in resting and exercising human muscle.” [1]

    Published in the Journal of Nutrition, a 2006 placebo-blind study on 30 healthy volunteers showed that “BCAA supplementation prior to squat exercise decreased delayed-onset muscle soreness and muscle fatigue.” [2]

    A study on 4,429 men and women from the U.S., U.K., China, and Japan shows that BCAA keeps people lean. It concluded that “higher dietary BCAA intake is associated with lower prevalence of overweight status/obesity” and that “weight loss induced by high-protein/low-carbohydrate diet may be partially explained by BCAA intake.” [3]


    In 2011, 37 college athletes (football & wrestling) where used to examine the effectiveness of Beta-Alanine in tests of anaerobic power output. The study found that “Beta-Alanine appears to have the ability to augment performance and stimulate lean mass accrual in a short amount of time.” [4]

    A double-blind study on cyclists discovered that Beta-Alanine promotes muscular endurance and reduces fatigue. During the final sprint of the time-trial study, “Beta-Alanine on average increased peak power output by 11.4%”. Researchers concluded that “oral Beta-Alanine supplementation can significantly enhance sprint performance at the end of an exhaustive endurance exercise bout.” [5]

    A 30 day placebo-controlled study examining the effect of Beta-Alanine supplementation in collegiate football players on anaerobic performance measures found that “short-duration beta-alanine supplementation increases training volume and reduces subjective feelings of fatigue.” [6]


    I'm Vegan. Can I Use Your BCAA's?

    Yes. Unlike many supplement companies who use human hair or bird feathers, our BCAAs come from 100% botanical sources.

    Should I take BCAAs before or after my workout?

    There is no 1-size-fits-all answer here. Many people are reporting success from using our BCAAs both before and after workouts. Additionally, there is research that supports the use of BCAAs in both instances. 

    Historically, BCAAs are extremely beneficial for recovery post-workout. The addition of beta-alanine in our BCAAs increases endurance, making them a potent addition to your pre-workout stack.

    All matters of health and fitness are highly individual, so we suggest experimenting and choosing the usage protocol that works best for your goals.

    Is there a money-back guarantee?

    Yes! All orders purchased through are backed by our 30-day 100% money back guarantee from the date of purchase. If in the unlikely event you are not completely satisfied with Natural BCAAs, you can email our support desk for an RMA form and Natural Stacks Inc will refund your order after bottles are returned (shipping & handling charges are not refundable).
