HelloPharmacist Scorecard of B1 Natural Berry Flavor by BariMelts

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 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains 1 active ingredient: thiamine (vitamin B1). Thiamine is an essential B vitamin your body needs for energy production, nerve function, and metabolism.

BariMelts formulates it as a dissolvable tablet for absorption.

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: B vitamin supplementation for bariatric patients.
  • We looked for evidence on: Thiamine deficiency, Wernicke-Korsakoff syndrome (WKS), Beriberi, Vitamin B1 deficiency.
  • 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).

Thiamine is effective for treating thiamine deficiency and Wernicke-Korsakoff syndrome (a serious brain condition caused by severe B1 lack). It's possibly effective for period pain (dysmenorrhea).

For mosquito repellent and heart failure, the evidence we hold shows it's possibly ineffective — so don't rely on it for those purposes.

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 in the amounts you'll find in supplements. Allergic reactions are rare but can happen — dermatitis and other skin reactions have occasionally been reported.

Thiamine is needed during pregnancy and breastfeeding, but use supplement doses only as your doctor or midwife advises rather than self-dosing.

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.

If you take trimethoprim (Proloprim), an antibiotic, you should know it may raise thiamine blood levels — a Minor interaction. Check your exact medications with the search tool on this page before you start.
