The Promise

Concentrated BCAAs — branched-chain amino acids in vegetarian forms

Free-form L-leucine, L-isoleucine and L-valine supplied as vegetarian capsules or powder.

Core ingredients and amounts

Each vegetable capsule supplies 600 mg L‑leucine, 300 mg L‑isoleucine and 150 mg L‑valine; one powder scoop supplies 1,500 mg L‑leucine, 750 mg L‑isoleucine and 750 mg L‑valine.

Free‑form amino acid delivery

Branched chain amino acids are provided in free‑form L‑amino acid formats for capsule and powder presentations.

Vegetarian capsule and mixable powder

Available as an easy‑to‑swallow vegetable capsule and as a powder that mixes with about 10 ounces of water or juice.

Source and purity notes

Isoleucine and valine are produced via corn dextrose fermentation; leucine is extracted from protein and processed and purified.

Why It Works

Why this formulation matters — specific amino acid forms, doses, and combination

The precise free‑form L‑amino acids, their ratios, and recommended daily totals guide practical dosing choices.

01

Free‑form L‑amino acids

Free‑form L‑leucine, L‑isoleucine and L‑valine are the molecular forms listed and are not bound in intact protein.

02

Concentration and ratio

Capsules provide a 4:2:1 ratio of leucine:isoleucine:valine per capsule; the powder maintains the same ratio at a higher per‑scoop dose.

03

Not metabolized by the liver

Branched chain amino acids are noted as unique among amino acids in that they are not metabolized by the liver.

04

Daily recommendation range

Recommended total intake is 1,200–3,000 mg per day, delivered in divided doses between meals.

BCAA (amino acids) – BCAA or branched chain amino acids, are often sought after by athletes seeking optimal muscle mass. The branched chained amino acids leucine, isoleucine and valine, are known to help boost energy levels, while offsetting the breakdown of muscle protein breakdown occurring during exercise. Pure Encapsulations offers BCAA in an easy to swallow vegetarian capsule. Best seller for athletes, please call us to speak with one of our vitamin experts, we are happy to help.

What Is It?

The branched chain amino acids (BCAAs) are leucine, isoleucine, and valine. These essential amino acids provide nutritional support for athletes and individuals seeking optimal lean muscle mass. Branched chain amino acids are unique in that they are not metabolized by the liver.*

Uses For BCAAs

Promotes Healthy Muscle Mass: BCAAs may play a role in athletic support by promoting muscle nitrogen, enhancing alanine and glutamine production, decreasing lactate production and boosting energy while attenuating protein breakdown These actions help to sustain muscle work capacity and recovery. Studies have reported that post-exercise protein intake helps to enhance the repair of muscle protein. Additionally, some research has suggested that BCAAs may moderate the progression of central nervous system fatigue during exercise, supporting mental performance.*

What Is The Source?

Isoleucine and valine are produced from corn dextrose fermentation. Leucine is originally extracted from protein and is extensively processed and purified.

Recommendations

Pure Encapsulations recommends 1200-3000 mg per day, in divided doses, between meals.

Are There Any Potential Side Effects Or Precautions?

If pregnant or lactating, consult your physician before taking this product. Until more research is conducted, individuals with ALS, a history of depression, or kidney or liver disease should consult a doctor before supplementing with BCAAs.
