Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 5 of its 5 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

BCAA 2200 contains 5 ingredients, including three amino acids—L-leucine, L-isoleucine, and L-valine—plus vitamin B6 and vitamin E. The three amino acids are branched-chain amino acids (BCAAs), a group your muscles use directly for repair and fuel during and after exercise.

The product also includes several inactive ingredients: soybean oil, gelatin, glycerin, soy lecithin, and titanium dioxide.

Does it work?

Moderate evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: muscle support and amino acid composition.
  • We looked for evidence on: Exercise-induced muscle damage, Muscle protein synthesis, Athletic performance, Muscle recovery.
  • The strongest evidence on file: Vitamin E is rated "Possibly Effective" for Exercise-induced muscle damage (Natural Medicines).

The effectiveness data we hold covers only the vitamins in this product, not the BCAAs. Vitamin B6 is effective for treating sideroblastic anemia (a blood disorder) and vitamin B6 deficiency itself, likely effective for high homocysteine levels (a heart-health marker), and possibly effective for pregnancy-related nausea and vomiting.

Vitamin E is effective for vitamin E deficiency and a rare inherited condition called ataxia with vitamin E deficiency (AVED), and possibly effective for Alzheimer's disease, beta-thalassemia, and G6PD deficiency. We hold no effectiveness data for the BCAA amino acids themselves.

The evidence, ingredient by ingredient Vitamin B6 Vitamin E

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Vitamin B6 is generally well tolerated at doses under 100 mg daily, though high doses over time can damage nerves (sensory neuropathy). Common side effects at any dose include nausea, headache, and heartburn.

Vitamin E from food and standard supplements is safe, but high-dose long-term supplements may raise your bleeding risk. Rare serious side effects from high-dose vitamin E include bleeding and hemorrhagic stroke.

Both vitamins carry caution labels for pregnancy and breastfeeding—vitamin B6 is rated likely safe in pregnancy but possibly unsafe (talk to your doctor before taking it for morning sickness), and vitamin E is possibly safe in pregnancy but you should check with your doctor before high-dose supplements while breastfeeding.

Formula

BCAA 2200 benefits: BCAAs are especially important for bodybuilders since they comprise a large percentage of the amino acid composition of muscle. BCAAs are also the only aminos that are directly metabolized in the muscle as opposed to the liver. Provides dual benefits since BCAAs can be used to build protein or broke down in muscle to supply a direct source of energy. BCAAs provide muscle nitrogen support for a variety of metabolic functions, which can be especially important during heavy training. Enhanced with high potency vitamin B-6, which plays an essential role in BCAA metabolism for optimal usage.

Vitamin E8 drug types · 764 drugs

Alkylating Agents

Theoretically, antioxidant effects of vitamin E might reduce the effectiveness of alkylating agents.
There's concern that antioxidants could reduce the activity of chemotherapy drugs which generate free radicals, such as cyclophosphamide, chlorambucil, carmustine, busulfan, and thiotepa. However, some researchers theorize that antioxidants might make chemotherapy more effective by reducing oxidative stress that might interfere with apoptosis (cell death) of cancer cells. More evidence is needed to determine what effect, if any, antioxidants such as vitamin E have on chemotherapy. Advise patients to consult their oncologist before using vitamin E supplements, especially in high doses.

Likelihood Possible Evidence D
Anticoagulant/Antiplatelet Drugs

Concomitant use of vitamin E and anticoagulant or antiplatelet agents might increase the risk of bleeding.
Vitamin E seems to inhibit of platelet aggregation and antagonize the effects of vitamin K-dependent clotting factors. These effects appear to be dose-dependent, and are probably only likely to be clinically significant with doses of at least 800 units daily. Mixed tocopherols, such as those found in food, might have a greater antiplatelet effect than alpha-tocopherol. RRR alpha-tocopherol (natural vitamin E) 1000 IU daily antagonizes vitamin K-dependent clotting factors. Advise patients to avoid high doses of vitamin E, especially in people with low vitamin K intake or other risk factors for bleeding.

Likelihood Possible Evidence B
Antitumor Antibiotics

Theoretically, antioxidant effects of vitamin E might reduce the effectiveness of antitumor antibiotics.
There's concern that antioxidants could reduce the activity of antitumor antibiotic drugs such as doxorubicin, which generate free radicals. However, some researchers theorize that antioxidants might make chemotherapy more effective by reducing oxidative stress that might interfere with apoptosis (cell death) of cancer cells. More evidence is needed to determine what effect, if any, antioxidants such as vitamin E have on chemotherapy involving antitumor antibiotics. Advise patients to consult their oncologist before using vitamin E supplements, especially in high doses.

Likelihood Possible Evidence D
Cyclosporine (Neoral, Sandimmune)

A specific form of vitamin E might increase absorption and levels of cyclosporine.
There is some evidence that one specific formulation of vitamin E (D-alpha-tocopheryl-polyethylene glycol-1000 succinate, TPGS, tocophersolan, Liqui-E) might increase absorption of cyclosporine. This vitamin E formulation forms micelles which seems to increase absorption of cyclosporine by 40% to 72% in some patients. However, this interaction is unlikely to occur with the usual forms of vitamin E.

Likelihood Unlikely Evidence B
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, vitamin E might induce metabolism of CYP3A4, possibly reducing the levels CYP3A4 substrates.
Vitamin E appears to bind with the nuclear receptor, pregnane X receptor (PXR), which results in increased expression of CYP3A4. Although the clinical significance of this is not known, use caution when considering concomitant use of vitamin E and other drugs affected by these enzymes.

Likelihood Possible Evidence D
Selumetinib (Koselugo)

Taking selumetinib with vitamin E can result in a total daily dose of vitamin E that exceeds safe limits and therefore might increase the risk of bleeding.
Selumetinib contains 48-54 IU vitamin E per capsule. The increased risk of bleeding with vitamin E appears to be dose-dependent. Be cautious when using selumetinib in combination with supplemental vitamin E, especially in patients at higher risk of bleed, such as those with chronic conditions and those taking antiplatelet drugs.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Using vitamin E with warfarin might increase the risk of bleeding.
Due to interference with production of vitamin K-dependent clotting factors, use of more than 400 IU of vitamin E daily with warfarin might increase prothrombin time (PT), INR, and the risk of bleeding,. At a dose of 1000 IU per day, vitamin E can antagonize vitamin K-dependent clotting factors even in people not taking warfarin. Limited clinical evidence suggests that doses up to 1200 IU daily may be used safely by patients taking warfarin, but this may not be applicable in all patient populations.

Likelihood Possible Evidence B
Niacin

Vitamin E might decrease the beneficial effects of niacin on high-density lipoprotein (HDL) cholesterol levels.
A combination of niacin and simvastatin (Zocor) effectively raises high-density lipoprotein (HDL) cholesterol levels in people with coronary disease and low HDL levels. Clinical research shows that taking a combination of antioxidants (vitamin C, vitamin E, beta-carotene, and selenium) along with niacin and simvastatin (Zocor) attenuates this rise in HDL, specifically the HDL-2 and apolipoprotein A1 fractions, by more than 50%. Vitamin E alone combined with a statin does not seem to decrease HDL levels. It is not known whether the adverse effect on HDL is due to one of the other antioxidants or to the combination. It also is not known whether it will occur in other patient populations.

Likelihood Possible Evidence A
Vitamin E full monograph & interactions

Vitamin B65 drug types · 210 drugs

Amiodarone (Cordarone)

Theoretically, vitamin B6 might increase the photosensitivity caused by amiodarone.
Despite initial case reports suggesting that pyridoxine may have a protective effect against amiodarone-induced photosensitivity, preliminary clinical research suggests that pyridoxine may actually exacerbate this adverse effect.

Likelihood Possible Evidence B
Antihypertensive Drugs

Theoretically, vitamin B6 may have additive effects when used with antihypertensive drugs.
Research in hypertensive rats shows that vitamin B6 can decrease systolic blood pressure. Similarly, clinical research in patients with hypertension shows that taking high doses of vitamin B6 may reduce systolic and diastolic blood pressure, possibly by reducing plasma levels of epinephrine and norepinephrine.

Likelihood Possible Evidence B
Phenobarbital (Luminal)

High doses of vitamin B6 may reduce the levels and clinical effects of phenobarbital.
Preliminary clinical evidence suggests that vitamin B6 200 mg daily can reduce plasma levels of phenobarbital, possibly by increasing metabolism. It is not known whether lower doses have any effect. Advise people taking phenobarbital to avoid high doses of vitamin B6.

Likelihood Possible Evidence D
Phenytoin (Dilantin)

High doses of vitamin B6 may reduce the levels and clinical effects of phenytoin.
Preliminary clinical evidence suggests that vitamin B6 200 mg daily can reduce plasma levels of phenytoin, possibly by increasing metabolism. It is not known whether lower doses have any effect. Advise people taking phenytoin to avoid high doses of vitamin B6.

Likelihood Possible Evidence D
Levodopa

Vitamin B6 may increase the metabolism of levodopa when taken alone, but not when taken in conjunction with carbidopa.
Vitamin B6 (pyridoxine) enhances the metabolism of levodopa, reducing its clinical effects. However, this interaction does not occur when carbidopa is used concurrently with levodopa (Sinemet). Therefore, it is not likely to be a problem in most people.

BCAA 2200 by Myology: Common Questions

Does BCAA 2200 by Myology interact with any medications?
Yes. Based on its ingredients, BCAA 2200 has a known interaction with 934 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
BCAA 2200 contains 5 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Is vitamin B6 in this product safe during pregnancy?
Vitamin B6 is rated likely safe in pregnancy from normal dietary amounts and standard supplements. However, it's also rated possibly unsafe when used for specific purposes like morning sickness—so only take it during pregnancy under your doctor's guidance. There isn't enough data on file for the amino acids to say either way; talk to your doctor or pharmacist about those.
What's the risk of high-dose vitamin E in this product?
High-dose vitamin E over time can increase your bleeding risk, especially if you take blood thinners or antiplatelet drugs. It may also raise the rare risk of hemorrhagic stroke. The data we hold doesn't tell us the exact dose of vitamin E in this product, so check the label and discuss it with your pharmacist if you're on any blood-thinning medication.
Can vitamin B6 at high doses cause side effects?
Vitamin B6 is well tolerated at doses under 100 mg daily. Common side effects include nausea, headache, and heartburn. At very high doses (especially over 1000 mg daily or with long-term use), it can cause nerve damage (sensory neuropathy), which is rare but serious. This product's dose isn't on file, so check the label.
Will this product interfere with my seizure medication?
Yes, potentially. High doses of vitamin B6 may reduce blood levels and effectiveness of phenytoin (Dilantin) and phenobarbital (Luminal). Before starting this product, talk to your doctor or pharmacist about the dose and whether it's safe for you.
What are branched-chain amino acids (BCAAs) used for?
The three BCAAs in this product—leucine, isoleucine, and valine—are amino acids your muscles use directly for repair and fuel during and after exercise. Effectiveness data we hold doesn't cover these specific ingredients in this product.
Can I take this if I'm breastfeeding?
Vitamin B6 is rated likely safe while breastfeeding. Vitamin E is rated likely safe but also possibly unsafe (the data shows mixed results), so check with your doctor before taking high-dose supplements. We have no breastfeeding data on file for the amino acids—talk to your pharmacist for personalized advice.
