HelloPharmacist Scorecard of BCAA Powder Watermelon by Precision Engineered
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
This powder contains 4 active ingredients: vitamin B6 and three branched-chain amino acids (BCAAs) — L-leucine, L-isoleucine, and L-valine. The BCAAs are amino acids your body uses to support muscle function and recovery.
The product also contains several inactive ingredients — natural flavors, citric acid, sweeteners (acesulfame potassium and sucralose), silica, and food colorings (FD&C Red No. 40 and FD&C Blue No.
1) — to create the watermelon flavor and texture.
Does it work?
Strong evidence
Vitamin B6 is effective for treating sideroblastic anemia (a type of bone marrow disorder) and vitamin B6 deficiency itself, and it's effective for a rare genetic condition called pyridoxine-dependent epilepsy. It's likely effective for lowering homocysteine (an amino acid linked to heart and blood vessel risk).
It's possibly effective for pregnancy-related nausea and vomiting, though it should only be used under a doctor's guidance during pregnancy. We don't hold effectiveness data in our system for the three branched-chain amino acids in this product, so we cannot tell you what the evidence shows about their role in this formula.
How safe is it?
Well-documented data
Vitamin B6 is well tolerated at doses below 100 mg daily. Common side effects at higher doses include abdominal pain, allergic reactions, headache, heartburn, loss of appetite, nausea, and drowsiness.
The serious concern is nerve damage (sensory neuropathy) — it's rare but can happen with high doses, especially doses over 1,000 mg daily or cumulative doses of 1,000 grams or more, though it can occur at lower amounts too. We don't hold pregnancy or breastfeeding safety data for vitamin B6 in this product's information, nor do we have any safety information on file for the three amino acids.
If you're pregnant or breastfeeding, talk with your doctor or pharmacist before taking this product.
Meds to double-check
Moderate interaction found
Check with your pharmacist or doctor before taking this product if you use antihypertensive (blood pressure) medications, the heart drug amiodarone (Cordarone), seizure medications like phenobarbital (Luminal) or phenytoin (Dilantin), or levodopa without carbidopa. These are the drug types with documented interactions to vitamin B6.
The bottom line
Scorecard at a glanceFully disclosed formula with strong clinical evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.
If you take blood pressure medications, heart rhythm drugs, or seizure medications, check your exact prescriptions with the tool below before starting this powder. Anyone taking levodopa alone (not Sinemet) should also check first.
The vitamin B6 content is the main safety concern — it's fine at normal supplement levels but can cause nerve damage at very high doses over time.

BCAA Powder Watermelon by Precision Engineered Drug Interactions
HelloPharmacist Interaction Report
BCAA Powder Watermelon by Precision Engineered contains vitamin B6, which does interact with several medications.
The most serious concern is with blood pressure medications (antihypertensive drugs) — vitamin B6 may add to their effect and lower your blood pressure further, which is a Moderate-severity interaction. If you take any medication to control blood pressure, you'll want to check it against this product.
Read the full breakdown — every affected drug type, severity by severity
Vitamin B6 also interacts with the heart rhythm medication amiodarone (Cordarone) at Moderate severity, potentially making your skin more sensitive to sunlight. It can reduce how well two seizure medications work — phenobarbital (Luminal) and phenytoin (Dilantin) — also Moderate severity.
And if you take levodopa alone (not combined with carbidopa) for Parkinson's disease, vitamin B6 may reduce its effectiveness; however, this doesn't happen if you're taking the combination form called Sinemet, which is a Minor-severity interaction.
The product also contains three amino acids — L-leucine, L-isoleucine, and L-valine — for which we hold no interaction data and cannot check. Altogether, these interactions span 208 individual medications.

For each ingredient in BCAA Powder Watermelon with known interactions, here are the types of medications it 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.
