HelloPharmacist Scorecard of Benfotiamine 150 mg by Doctor's Best

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.

From our pharmacy team — supplement deep dive

What’s inside

Full disclosure
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 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains 2 active ingredients: benfotiamine (a fat-soluble form of thiamine, also called vitamin B1) and L-Leucine (an amino acid your body uses for muscle and protein metabolism). The capsule also holds inactive ingredients — hypromellose, microcrystalline cellulose, and silicon dioxide — which are fillers and capsule material.

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: support healthy glucose metabolism.
  • We looked for evidence on: Diabetic neuropathy, Diabetic nephropathy, glucose control, metabolic health.
  • The strongest evidence on file: Benfotiamine is rated "Possibly Effective" for Diabetic neuropathy (Natural Medicines).
  • Also on file: Benfotiamine is rated "Possibly Ineffective" for Diabetic nephropathy.

Benfotiamine is possibly effective for diabetic nerve damage (neuropathy), meaning some evidence supports it but more research is needed. For diabetic kidney damage, the evidence suggests it's likely ineffective.

For other uses — alcohol use disorder, Alzheimer disease, and general peripheral nerve problems — there isn't enough reliable evidence to say whether it works. We hold no effectiveness rating for L-Leucine on this page.

The evidence, ingredient by ingredient Benfotiamine

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 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Benfotiamine is generally well tolerated in the studies we have, but long-term safety isn't fully known, so the caution is to use it only if your doctor advises you to. In one clinical trial of 98 people taking 300–600 mg daily for 6 weeks, allergic skin reactions occurred in two people and mild stomach discomfort in six — rates no different from placebo.

Safety during breastfeeding hasn't been well studied, so caution is advised; pregnancy safety data isn't on file. Talk with your doctor or pharmacist about whether this is right for you if you're pregnant or breastfeeding.

Side effects, ingredient by ingredient Benfotiamine

Meds to double-check

No known interactions
Known Interaction Concern · database check
No known interactions

No medication interactions are currently documented for the matched ingredients — that isn't a guarantee none exist.

Why this rating?
  • None of the 1 matched ingredient has a documented medication interaction on file.

No interactions are documented in our data for benfotiamine. That doesn't mean none could occur — it means the research we have doesn't show them.

Run your medications through the checker on this page to be sure, and ask your pharmacist if you have questions.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. No medication interactions are currently documented, and safety information is well characterized.

Benfotiamine may be worth considering if you have diabetic nerve damage and your doctor recommends it — the evidence points to possible benefit there. If you're pregnant, breastfeeding, or taking other medications, check with your doctor or pharmacist first.

Long-term safety isn't fully established, so it's not a supplement to take indefinitely without medical oversight.

Benfotiamine activates transketolase, a cellular enzyme essential for glucose metabolism pathway. It helps support the circulatory and nervous systems with radical-scavenging action against oxidative stress, providing a positive influence on Advanced Glycation End products (AGEs). Helps support healthy cells in the presence of blood glucose Helps support cellular processes fueled by glucose metabolites Helps radical-scavenging acting to support against oxidative stress
