This B-complex hits clinical-strength doses across the board for energy, brain function, and nervous system support. You're getting 100 mg each of **Thiamine**, **Vitamin B6**, and **Niacin**, plus 500 mg of **Pantothenic Acid** — all at or near the top of their studied ranges. **Folate** at 680 mcg comes as methylfolate, the bioactive form, which is a real advantage if your body doesn't convert folic acid efficiently.
**Vitamin B12** gives you methylcobalamin at 300 mcg — within clinical range but on the lower end. **Riboflavin** at 75 mg uses a mix of standard and active forms. The formula also includes 1,000 mcg of **Biotin** and 100 mg of **Inositol**, though the inositol is well below the 2,000–4,000 mg range used in mood and hormonal research.
The main tradeoff is B6 at 100 mg, which sits right at the tolerable upper limit. If you're taking other supplements containing B6, keep an eye on your total daily intake to avoid the risk of nerve-related side effects over time.
