Despite the name, this B complex is missing two key players: **Vitamin B12** and **Folate** are completely absent. Of the B vitamins included, only **Niacin** at 50mg lands within the typical clinical range (25–500mg). **Thiamine**, **Riboflavin**, **Vitamin B6**, and **Pantothenic Acid** are all dosed at 20–60% of the studied effective range, so you're getting partial amounts across the board.

**Vitamin C** at 300mg is the strongest ingredient here — a reasonable daily dose for immune and antioxidant support, though the ascorbic acid form absorbs less efficiently at higher doses. The 175mg of **Calcium** from carbonate requires stomach acid to absorb and covers less than 18% of your daily needs.

The biggest gap is the missing B12 and folate. These two work together in red blood cell formation and nervous system function, and their absence means this product can't serve as a complete B complex. If you're looking for full B-vitamin coverage, you'd need to supplement those separately.
