Analysis

The 21st Century B-1 100 mg supplement provides a potent dose of Thiamine (Vitamin B1) in the form of Thiamine Hydrochloride, alongside a moderate amount of Calcium Carbonate. Thiamine is crucial for converting carbohydrates into energy, supporting nerve function, and maintaining cardiovascular health. The 100mg dosage is substantial and well above the recommended daily allowance, indicating its utility for addressing deficiencies or supporting higher metabolic demands. The inclusion of 180mg of Calcium Carbonate offers a complementary benefit for bone health, though this form of calcium is best absorbed with food, and the dosage is relatively low for comprehensive calcium supplementation alone. Nutritionists frequently highlight the importance of B vitamins for overall metabolic health. The product's extremely low price per serving (3 cents) makes it a highly economical choice for individuals seeking targeted B1 supplementation. Online reviews, though limited compared to some popular B-complex products, generally indicate satisfaction with its energy-boosting effects, aligning with Thiamine's known benefits.

Pros
  • Extremely cost-effective with a very low price per serving.
  • Provides a substantial 100mg dose of Thiamine, effective for B1 supplementation.
  • Thiamine Hydrochloride is a well-established and readily absorbed form of Vitamin B1.
Cons
  • The 180mg Calcium Carbonate dose is relatively low for significant bone support.
  • Calcium Carbonate absorption is best with food due to its reliance on stomach acid.
  • Includes broad claims like "Testosterone Support" which are not directly supported by the ingredients.
