The Vitamin Shoppe Vitamin B1 100 mg
Brand: The Vitamin Shoppe · Form: CAPSULE [E0159]
Our assessment
The evidence shows that Vitamin B1 (thiamine) is essential for converting food into energy, and a 100 mg dose is well above the standard RDA. For most people, a balanced diet provides sufficient B1, but supplementation can be beneficial for specific conditions such as diabetes or alcohol use disorder. Data on this specific product's efficacy is not available, but the ingredient itself is well-established [NIH ODS].
How it works
Think of Vitamin B1 as a key metabolic spark plug — it helps your body turn carbohydrates into usable energy for your brain, nerves, and heart. It also plays a role in nerve signal transmission and muscle contraction [NIH ODS].
Safety profile
Vitamin B1 is considered very safe, as it is water-soluble and excess amounts are typically excreted in urine. FDA received 0 adverse event reports for this specific product. Data not available for side effects specific to this formulation. At high supplemental doses, some people may experience mild stomach upset [NIH ODS].
Our recommendation
Start with one 100 mg tablet daily, preferably with food. If you have a known deficiency or a condition that increases your need (like diabetes or heavy alcohol use), this dose is appropriate. For general wellness, a lower dose or food sources like whole grains and pork may be sufficient [NIH ODS].
