HelloPharmacist Scorecard of BCAA 5000 Blue Raspberry by MET-Rx
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 product has 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 build and repair muscle tissue; they're popular among athletes and people doing resistance training.
Vitamin B6 is a B vitamin involved in protein and amino acid metabolism, as well as nerve and immune function. The remaining ingredients are inactive — flavoring, sweeteners, citric acid, and colorants that make the powder taste and look good.
Does it work?
Couldn't assess
Vitamin B6 is effective for treating sideroblastic anemia (a blood disorder) and B6 deficiency, and likely effective for lowering homocysteine (an amino acid linked to heart disease). It's possibly effective for pregnancy-related nausea.
We hold no effectiveness data for the branched-chain amino acids in this product, so we cannot tell you from our data whether they work for muscle building or athletic recovery.
How safe is it?
Well-documented data
Vitamin B6 is well tolerated at doses under 100 mg daily. The safety notes caution that high doses taken over time can damage nerves — a condition called sensory neuropathy.
Very high doses (over 1,000 mg daily or a lifetime total of 1,000 grams or more) pose the greatest risk, but nerve damage can occur at lower doses too. Common mild side effects at normal doses include headache, nausea, heartburn, and stomach pain.
During pregnancy, vitamin B6 is rated Likely Safe at standard levels and has been used under medical supervision for morning sickness, though you should discuss use with your doctor. It's rated Likely Safe during breastfeeding.
Meds to double-check
Moderate interaction found
Double-check this product if you take blood pressure medications (antihypertensive drugs), seizure medications like phenobarbital or phenytoin, the heart rhythm drug amiodarone, or levodopa for Parkinson's disease. No interactions are documented for the three branched-chain amino acids we could check — the concerns are from vitamin B6 alone.
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.
This product is mainly for people looking to add branched-chain amino acids for muscle support during workouts. If you take blood pressure medication, seizure drugs, amiodarone, or levodopa, check your specific medications with the tool below before starting — vitamin B6 can interact with these.
Stick to the recommended dose and talk with your pharmacist if you have questions about how it fits with your health routine.

BCAA 5000 Blue Raspberry by MET-Rx Drug Interactions
HelloPharmacist Interaction Report
MET-Rx BCAA 5000 Blue Raspberry contains vitamin B6, which has documented interactions 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, a Moderate-severity interaction. This product may also increase sun sensitivity caused by the heart rhythm drug amiodarone.
Read the full breakdown — every affected drug type, severity by severity
Vitamin B6 at high doses can reduce how well your body uses two seizure medications: phenobarbital and phenytoin. If you take either of these, high-dose B6 may make them less effective.
Additionally, if you take levodopa alone for Parkinson's disease, B6 might speed up how your body clears it — though this doesn't happen if you're on the combination product carbidopa-levodopa (Sinemet).
We could not check the three branched-chain amino acids in this product — L-leucine, L-isoleucine, and L-valine — because no interaction data is available for them. Altogether, these interactions span 208 individual medications.
If you're on any blood pressure medicine, a seizure drug, amiodarone, or Parkinson's medication, use the search tool below to verify your specific drugs before you start.

For each ingredient in BCAA 5000 Blue Raspberry 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.
