Choosing the right Vitamin B1 (thiamine) supplement matters whether you want basic daily support, targeted nerve or glucose metabolism benefits, or a highly bioavailable form. These recommendations come from product specification analysis, lab/GMP sourcing checks, hands-on testing of packaging/serving practicality, and synthesis of expert and consumer feedback.
Considerations: how we tested and evaluated
We evaluated candidates across several practical and clinical dimensions and gave greater weight to real-world usefulness and verified quality signals:
- Formulation & bioavailability: plain thiamine (water-soluble) vs. benfotiamine (fat-soluble, higher absorption) and presence of complementary nutrients (e.g., magnesium, B6, ALA).
- Dose & servings: per-serving mg, capsules/tablet count, and cost per serving.
- Manufacturing & quality: GMP/FDA facility statements, third-party testing (e.g., USP), allergen labeling, and country of manufacture.
- User experience: taste/texture for gummies, pill size, recommended dosing convenience.
- Safety & labeling clarity: transparent ingredient lists and appropriate usage directions.
- Expert & consumer signals: pharmacist/clinician recommendations, verified reviews, and common user-reported effects.
Testing combined hands-on checks (capsule size, ease-of-use, label clarity), cross-referencing technical specs, and scoring each product for value, effectiveness, and trustworthiness. Those scores informed the final rankings.
B-1 100 mg Tablet
A straightforward, economical 100 mg thiamine tablet from a respected supplement company. Offers reliable daily B1 support at a low price, easy once-daily dosing, and simple ingredient labeling—good for budget-conscious users who want basic nervous system and energy metabolism support.
NOW Foods Vitamin B-1 100 mg — Best Budget Pick
NOW Foods delivers a no-frills, single-ingredient thiamine tablet at a very low price. Each tablet supplies 100 mg of thiamine with clear dosing (1 tablet daily). Standout points: dependable family-owned manufacturer, straightforward label, compact bottle and good pill size for swallowing. It lacks the enhanced bioavailability of benfotiamine, so it's best for users who want standard thiamine supplementation for energy metabolism and nervous system support without extra ingredients. Pros: very affordable, simple formulation, USA-packaged. Cons: not a benfotiamine form and no USP verification.
Benfotiamine Complex
A premium benfotiamine formula with liposomal claims and added cofactors (B6, magnesium, ALA) to support nerve health and glucose metabolism. Designed for users who need higher bioavailability and a more research-driven approach to thiamine supplementation.
Zaigon Benfotiamine 600 mg — Premium Choice
This product targets users needing higher absorption and targeted nerve/glucose support. It uses benfotiamine (a fat‑soluble thiamine derivative) and pairs it with vitamin B6, magnesium, and alpha-lipoic acid—ingredients that can synergize for nerve function and cellular glucose pathways. The label highlights a liposomal delivery claim for enhanced uptake and provides 120 vegetarian capsules (2‑capsule serving = 600 mg benfotiamine). Pros: clinically oriented formula, comprehensive co-nutrients, vegetarian capsules. Cons: higher price, dependent on liposomal claim that’s difficult to independently verify at retail, and may be more than casual users need.
Benfotiamine 600 mg
High-dose benfotiamine in a value-sized bottle (180 capsules) offering 90 servings. A good middle ground for users who want improved absorption of B1 without the premium price—suitable for long-term programs and those prioritizing per-serving cost.
Nutricost Benfotiamine 600 mg — Best Value for Money
Nutricost offers 600 mg of benfotiamine per serving in a 180‑capsule bottle (2 capsules per serving = 90 servings), delivering strong per‑serving value for a fat‑soluble thiamine form. Manufactured in an NSF/GMP‑inclined facility, it’s labeled gluten-free and vegan—good for sustained use when benfotiamine is desired for improved absorption or metabolic/nerve support. Pros: high dose, large bottle reduces cost-per-serving, clean labeling. Cons: capsules require two-per‑day serving, and some users may prefer added cofactors if looking for a broader neuropathic formula.
Trusted B1 Tablets
Nature Made 100 mg thiamine tablets with USP verification and pharmacist endorsement. A reliable, widely available choice for everyday thiamine supplementation — balances trust signals, clear labeling, and user-friendly dosing for general wellness.
Nature Made Vitamin B1 100 mg — Editors' Choice
Nature Made pairs a straightforward 100 mg thiamine tablet with USP verification and pharmacist-recommended branding—an important trust signal for many buyers. The formula is gluten-free, contains no colors or preservatives, and recommends one tablet daily with a meal. It’s ideal for users who prioritize third‑party verification and consistent manufacturing standards. Pros: USP verified, broad availability, pharmacist-recommended branding. Cons: standard thiamine (not benfotiamine), and single-ingredient formulation may not satisfy those seeking adjunct nutrients.
Comparison and quick overview
