HelloPharmacist Scorecard of Thiamin 50 by Biotics Research Corporation

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

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 11, 2026

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 3 of its 3 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Thiamin 50 contains 3 active ingredients. Thiamine (also called vitamin B1) is the primary one — it's an essential nutrient your body needs to convert food into energy and keep your nerves and heart working properly.

The other two actives, Superoxide Dismutase and Catalase, are enzymes; their roles in this formula aren't detailed in our data. You'll also find standard inactive ingredients like gelatin (the capsule), glycerin, and water.

Does it work?

Strong 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
Strong

Clinical evidence supports at least one of this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: Thiamine supplementation and deficiency support.
  • We looked for evidence on: Thiamine deficiency, Wernicke-Korsakoff syndrome (WKS), Fatigue, Cognitive function, Diabetic neuropathy, Beriberi — and 2 related terms.
  • The strongest evidence on file: Thiamine is rated "Effective" for Thiamine deficiency (Natural Medicines).
  • Also on file: Thiamine is rated "Effective" for Wernicke-Korsakoff syndrome (WKS).
  • Also on file: Thiamine is rated "Insufficient Reliable Evidence To Rate" for Cognitive function, Diabetic neuropathy, Fatigue.

Thiamine is effective for treating thiamine deficiency and Wernicke-Korsakoff syndrome, a serious neurological condition from severe thiamine shortage. It's rated possibly effective for dysmenorrhea (period pain), though the evidence is less clear.

For mosquito repellent and heart failure, the evidence suggests it's possibly ineffective. We don't have effectiveness data for Superoxide Dismutase or Catalase in our monographs.

The evidence, ingredient by ingredient Thiamine

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.

Thiamine is generally very safe when taken by mouth at normal doses. Rarely, it can cause skin reactions (dermatitis) or other allergic reactions — though when given by injection, anaphylactic shock is possible (also uncommon).

Thiamine is a nutrient your body needs during pregnancy and breastfeeding; if you're pregnant or nursing and want to take a supplement, use only the dose your doctor or midwife recommends.

Side effects, ingredient by ingredient Thiamine

Meds to double-check

Minor interactions only
Known Interaction Concern · database check
Minor only

Only Minor-severity interactions are documented for these ingredients.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Thiamine.
  • The most serious interaction on file is rated Minor.
  • For scale: 3 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Check this product against trimethoprim (Proloprim) if you take it for infection — it may raise how much thiamine stays in your blood. We have no interaction data for the other two active ingredients, so if you're on any medications, use the search tool below to be sure.

The bottom line

Scorecard at a glanceFully disclosed formula with clinical evidence supporting its stated purpose. Only minor medication interactions are documented, and safety information is well characterized.

This is a straightforward thiamine supplement, useful if you're deficient in B1 or recovering from alcohol-related thiamine problems. If you take trimethoprim for a bacterial infection, flagging it with your pharmacist is worth a minute.

Talk to your provider before adding any supplement to pregnancy or breastfeeding.

Thiamine1 drug type · 3 drugs

Trimethoprim (Proloprim)

Trimethoprim might increase blood levels of thiamine.
In vitro, animal, and clinical research suggest that trimethoprim inhibits intestinal thiamine transporter ThTR-2, hepatic transporter OCT1, and renal transporters OCT2, MATE1, and MATE2, resulting in paradoxically increased thiamine plasma concentrations.

They're enzymes listed as active ingredients, but we don't have detailed information about their specific roles in this formulation or how they work.
