Analysis

The NOW B-100 product aims to deliver a high-potency B-complex, with most included B vitamins (Thiamine, Riboflavin, Niacin, Pantothenic Acid) provided at 100mg per serving. This high potency supports various metabolic functions and energy production. However, a significant drawback is the complete absence of Vitamin B6 (Pyridoxine) from its ingredient list, which is a crucial B vitamin for a comprehensive 'B-100' formulation. Additionally, while the price per serving is excellent, the use of Cyanocobalamin for B12 is not the most bioavailable form, and the inclusion of nicotinic acid (Niacin) at 100mg alongside Niacinamide can lead to an uncomfortable, albeit harmless, 'niacin flush' for many users, which online reviews and nutritionist advice often highlight as a potential side effect.

Pros
  • Offers a very cost-effective price per serving, making high doses of several B vitamins accessible.
  • Provides robust 100mg doses of Thiamine (B1), Riboflavin (B2), Niacin (B3), and Pantothenic Acid (B5).
  • Includes other beneficial B-complex related compounds like Inositol, Choline, and PABA.
Cons
  • Lacks Vitamin B6 (Pyridoxine), a crucial and expected component of a complete 'B-100' complex.
  • Contains Vitamin B12 in the Cyanocobalamin form, which is synthetic and generally considered less bioavailable than Methylcobalamin.
  • The high dose of Niacin (nicotinic acid) can cause a common and often undesirable 'niacin flush' reaction.
Warnings
  • May cause a temporary 'niacin flush' (redness, itching, tingling) due to the high amount of nicotinic acid; this is generally harmless but can be uncomfortable.
  • Does not provide a complete spectrum of B vitamins, specifically missing Vitamin B6, which may necessitate supplementation with B6 from another source.
  • Individuals with specific health conditions, such as liver issues or those prone to gout, should consult a healthcare professional before taking high doses of Niacin.
