Buying Guide

Choose the right form: thiamine vs. benfotiamine

Thiamine hydrochloride provides standard B1, while benfotiamine is a fat-soluble derivative often used for higher tissue uptake and neuropathy support

Check dosage per serving

Products here range from ~250–500 mg per capsule; match potency to your health goal and consult a clinician for high-dose use

Look at capsule type and diet labels

If you prefer non-animal options, consider vegetarian or vegan caps like those used by Life Extension, BESTVITE, and NusaPure

Watch allergen and ingredient disclosures

Brands such as Nutricost and BESTVITE explicitly list gluten-free labeling—use those statements if you need allergen-free supplements

Consider intended use and supporting claims

Some benfotiamine products highlight blood-sugar or neuropathy support; match those supporting indications with your health goals and clinical advice
