HelloPharmacist Scorecard of BCAA 3300 by MHP Maximum Human Performance
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Full disclosure
BCAA 3300 contains 5 active ingredients: three branched-chain amino acids (L-leucine, L-isoleucine, and L-valine), plus riboflavin (vitamin B2) and vitamin B6. The three BCAAs are amino acids your body uses to build and repair muscle.
Riboflavin is a B vitamin that helps your body turn food into energy, and vitamin B6 plays a role in brain development and immune function. The product also includes several inactive ingredients like cellulose, calcium carbonate, and magnesium stearate, which are fillers and binders that hold the tablet together.
Does it work?
Couldn't assess
The facts we hold don't include effectiveness data for the branched-chain amino acids in this product. For riboflavin, we have no established effectiveness ratings in our data.
Vitamin B6 is effective for sideroblastic anemia and B6 deficiency, likely effective for high homocysteine levels (hyperhomocysteinemia), and possibly effective for pregnancy-induced nausea and vomiting—but the evidence isn't clear for other uses.
How safe is it?
Well-documented data
Riboflavin is very well tolerated and considered safe; any excess is removed through your urine. The most common side effects are dose-related nausea and bright yellow urine.
A small number of trial participants reported diarrhea and increased urination at high doses. Riboflavin is needed during pregnancy and breastfeeding and is safe at standard amounts, though talk with your provider about higher-dose supplements.
Vitamin B6 is well tolerated at doses under 100 mg daily. Common side effects include abdominal pain, headache, nausea, and vomiting.
At high doses over time—especially above 1,000 mg daily or cumulative doses of 1,000 grams or more—it can cause nerve damage (sensory neuropathy), though this can occur even at lower doses. Vitamin B6 is likely safe in pregnancy at recommended amounts but possibly unsafe at high doses; it's likely safe while breastfeeding.
Always avoid high doses unless your doctor advises otherwise.
Meds to double-check
Moderate interaction found
Before taking BCAA 3300, double-check if you use blood pressure medications (antihypertensives)—vitamin B6 may add to their effect. Also check for seizure medications like phenobarbital or phenytoin, the heart medication amiodarone, tetracycline antibiotics, and levodopa for Parkinson's disease.
The interaction checker below will search your specific medications.
The bottom line
Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
BCAA 3300 may be worth considering if you're looking to support muscle recovery with branched-chain amino acids and want the added B vitamins. If you take blood pressure medications, seizure medications, amiodarone, tetracycline antibiotics, or levodopa, you should check your exact medications against the interaction tool before starting.
Talk with your pharmacist about whether this product is right for you and your current medications.

General Statements
4:1:1 Leucine Loaded Increased Muscle Growth* Improved Recovery*
BCAAs are essential amino acids, which means the body cannot make them and they must be supplied through food or supplementation. An athlete's requirement for BCAAs is even higher than that of ordinary individuals because they serve as "building blocks" for muscle tissue and are also utilized for energy. BCAA 3300's higher levels of leucine, in conjunction with isoleucine and valine, allows for higher anabolic activity and optimal BCAA replenishment for athletes. Additionally, BCAA 3300 has a timed release delivery to provide a continual supply of these key amino acids for optimum anabolic and anti-catabolic effects.*
Branched Chain Amino Acids
MHP Maximum Human Performance
MHP's BCAA 3300 is a super-anabolic Branched Chain Amino Acid complex formulated in a powerful 4:1:1 ratio (leucine: isoleucine: valine) for maximum muscle building and recovery. This highly anabolic ratio sets MHP's BCAA 3300 apart from other formulas that use the outdated 2:1:1 ratio. The newest muscle-building and performance research reports that leucine is the most anabolic of all aminos and activates the mTOR anabolic pathway to increase protein synthesis for enhanced muscle growth and repair.*
mTOR Activated Anabolic Complex
The Most Anabolic BCAA Formula*
TIMED RELEASE
Formula
MHP's BCAA 3300 is the most scientifically advanced anabolic BCAA formula available and is a must for all serious body builders and athletes!*

BCAA 3300 by MHP Maximum Human Performance Drug Interactions
HelloPharmacist Interaction Report
BCAA 3300 by MHP Maximum Human Performance contains two ingredients with documented drug interactions: riboflavin and vitamin B6.
The most serious concern is vitamin B6's Moderate interaction with blood pressure medications (antihypertensives). Vitamin B6 may add to their blood-pressure-lowering effect, potentially causing your blood pressure to drop too much.
Read the full breakdown — every affected drug type, severity by severity
Vitamin B6 also has Moderate interactions with the heart rhythm medication amiodarone (Cordarone)—it may worsen sun sensitivity—and with two seizure medications, phenobarbital (Luminal) and phenytoin (Dilantin). High doses of vitamin B6 can reduce how well these seizure drugs work by speeding up how your body breaks them down.
Vitamin B6 has a Minor interaction with levodopa (a Parkinson's medication), though this doesn't apply if you take it with carbidopa (Sinemet). Riboflavin has a Moderate interaction with tetracycline antibiotics, which may theoretically reduce their effectiveness, though this hasn't been confirmed in humans.
We could not check three ingredients in this product—L-leucine, L-isoleucine, and L-valine—because we hold no interaction data for them. Altogether, these interactions span 228 individual medications.

For each ingredient in BCAA 3300 with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.
Vitamin B6
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.
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.
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.
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.
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.
Riboflavin
Tetracycline Antibiotics
Theoretically, taking riboflavin with tetracycline antibiotics may decrease the potency of these antibiotics.
In vitro research suggests that riboflavin may inhibit the potency of tetracycline antibiotics. It is not clear if this effect is clinically significant, as this interaction has not been reported in humans.
