Mix 1/2 a scoop (6.5g) in 8-10 oz (236-295 ml) of cold beverage. It will take a few minutes for all the powder to dissolve in the beverage. Best taken pre-workout, post-workout, or between meals.
Label warnings
Do not exceed recommended dose. Pregnant or nursing mothers, children under the age of 18, and individuals with a known medical condition should consult a physician before using this or any dietary supplement.

Graded honestly
What the evidence says
A flavored powder with 4 g of branched-chain amino acids (leucine, isoleucine and valine in a 2:1:1 ratio), 1 g of glutamine and 2.5 mg of vitamin B6 per serving. BCAAs are essential amino acids, but research does not show that taking them alone builds muscle or speeds recovery in people who already eat enough protein. Trials that found less muscle soreness used larger daily doses than one serving provides.
How it works
Leucine, isoleucine and valine are three of the nine essential amino acids, and they make up about 14 to 18 percent of the amino acids in muscle protein. Leucine acts as a signal that switches on muscle protein building after a meal or a workout. The limit is supply: building new muscle protein needs all nine essential amino acids, and BCAAs provide only three, so the signal fades unless the rest arrive from food or protein. Vitamin B6 is a helper for enzymes that process amino acids.
The dose in this product
One serving gives 4 g of BCAAs: about 2 g of leucine, 1 g of isoleucine and 1 g of valine. The label does not say how many servings to take a day; the product file assumes one.
How that compares with the studiesHide the comparison
Muscle soreness: a 2024 meta-analysis of 18 trials found less soreness 24 to 96 hours after hard exercise, but the soreness trials used 5 to 29 g a day, larger daily doses worked better, and many ran for several days. None used less than 5 g a day. Muscle protein building: in 10 trained men, 5.6 g of BCAAs after lifting raised muscle protein synthesis 22 percent over placebo, about half the response reported for whey protein with a similar amount of BCAAs.
Muscle and strength: the NIH notes that the short studies suggesting gains used about 10 to 14 g a day. Because one serving is below all of these, no claim is made for soreness, recovery, muscle growth or performance. With enough protein: complete proteins are about 25 percent BCAAs, so 16 g of complete protein supplies about as much as one serving of this product, along with the other essential amino acids that BCAAs lack.
The 1 g of glutamine is far below the amounts studied (about 0.3 g per kg of body weight a day or more).
- Moderate evidence
Vitamin B6 contributes to normal protein metabolism
This is a well-established nutrient function: vitamin B6 takes part in more than 100 enzyme reactions, most of them concerned with protein metabolism. One serving has 2.5 mg, or 147 percent of the Daily Value. Most people in the US already get enough from food, so extra is unlikely to add anything. [6]
- Moderate evidence
Supplies leucine, isoleucine and valine, three essential amino acids that are building blocks of muscle protein
That these amino acids are essential and are used to build muscle protein is established nutrition science. It is not evidence that this powder builds muscle or speeds recovery: the NIH says studies have not consistently shown that BCAA supplements enhance performance, build muscle or aid recovery, and the ISSN rates the evidence as limited or mixed. [1][5][4]
Strong evidence: many human trials agree, at the amount in this product. Moderate evidence: human trials mostly agree, but they are small, short or mixed. Early evidence: a few small human studies or lab work. Promising, not proven.
Safety
Who it is for, and who should ask first
Good fit if
- People who like a flavored drink around training and understand it does not replace protein
- People who train without eating first and want a light amino acid drink
- Not needed if you already reach your protein target: complete protein gives you BCAAs plus the other essential amino acids
Ask your doctor first if
- You are pregnant or nursing
- You are under 18
- You have liver disease
- You have diabetes
- You have ALS or another neurological or psychiatric condition
- You have maple syrup urine disease (an inherited disorder of BCAA breakdown)
- You take levodopa or anti-seizure medicine, or have any known medical condition
Interactions
- Levodopa: amino acids compete with it for absorption and for transport into the brain. Ask your doctor about timing.
- Anti-seizure medicines (phenytoin, phenobarbital): high-dose vitamin B6 (200 mg a day) can lower their blood levels. Whether small doses matter is not known, so tell your doctor.
- Other products with vitamin B6: add up your daily total (see stacking).
Possible side effects
- None known at 20 g a day or less for up to 6 weeks, according to the NIH fact sheet
Upper limit
BCAAs: the sources reviewed give no tolerable upper intake level; the NIH fact sheet says up to 20 g a day in divided doses appears safe and puts the upper safe intake of leucine alone at about 500 mg per kg a day (about 38 g for a 75 kg man). Vitamin B6: the US upper limit for adults is 100 mg a day; the European Food Safety Authority set a lower limit of 12 mg a day in 2023. One serving has 2.5 mg.
Combining with our other products
Vitamin B6 adds up across the line: BCAA 2:1:1 2.5 mg, Men's Multi 7.5 mg, Ashwagandha Complex 2.5 mg and Immune Support 1.7 mg. All four together give 14.2 mg a day, well under the US upper limit of 100 mg but above the 12 mg European limit; BCAA 2:1:1 plus Men's Multi alone is 10 mg. Glutamine: this product's 1 g plus L-Glutamine's 3.15 g is 4.15 g a day, a small amount.
Protein: a serving of Plant Protein already contains BCAAs along with the other essential amino acids, so adding this product on top gives little extra.

Answers
Questions people ask
Will this reduce muscle soreness?
That has not been shown at this dose. Pooled trials found less soreness with BCAAs, but they used 5 to 29 g a day, often for several days, and bigger daily doses worked better. One serving has 4 g.
Do BCAAs build muscle?
Not on their own. Leucine switches on muscle protein building, but your body needs all nine essential amino acids to build new protein, and BCAAs supply three. In a lab study, 5.6 g of BCAAs after lifting gave about half the response reported for whey protein with a similar amount of BCAAs.
I already eat plenty of protein. Do I need this?
Probably not. Complete proteins are about a quarter BCAAs, so 16 g of complete protein has roughly what one serving of this product has, plus the other essential amino acids. The NIH notes that evidence is inconsistent that BCAAs add anything beyond enough high-quality protein.
How many servings can I take a day?
The label gives one half-scoop serving and does not state a daily number; it also says not to exceed the recommended dose. Treat one serving a day as the limit unless your doctor says otherwise.
When should I take it?
The label suggests before or after a workout or between meals. Research has not settled whether timing changes the effect of protein or BCAAs.
What sweeteners are in it?
Sucralose and acesulfame potassium. Both are FDA-approved, with acceptable daily intakes of 5 mg per kg of body weight for sucralose and 15 mg per kg for acesulfame potassium. The label does not state how much each serving contains. The color comes from beet powder and grape skin extract.
Why is there vitamin B6 in it?
B6 helps enzymes that process amino acids. One serving has 2.5 mg, 147 percent of the Daily Value. Most people already get enough from food, so count it toward your total if you take a multivitamin.
Is the glutamine doing anything?
At 1 g, no trial supports an effect. Studies of glutamine for exercise used far more, about 0.3 g per kg of body weight a day or higher, which is roughly 20 g or more.
