This B complex uses bioactive forms across the board — your body can absorb and use each vitamin directly without conversion. That matters especially for **Folate** and **B12**, which work together to support DNA synthesis, red blood cell formation, and mood regulation. You're getting 400mcg of methylfolate and 400mcg of **B12** as methylcobalamin, both within studied ranges.

**Thiamine** at 110mg and **Pantothenic Acid** at 110mg are generously dosed for energy metabolism and stress response. **Niacin** at 140mg (mostly flush-free niacinamide) is solid. However, **Riboflavin** at 10mg and **B6** at 10mg sit below the typical 25mg B-complex floor — the premium active forms help with utilization, but you're still getting less than half the usual dose.

The weak spot is **Choline** at 28mg — well below the 100mg minimum meaningful supplemental dose. At this level, it's not contributing much to the brain and liver support you'd want from choline.
