For your energy and metabolic support, this B complex delivers solid doses, with most B vitamins landing within the clinical range. **Vitamin B6** at 34mg uses a blend that includes the active P5P form your body can use directly, and **Pantothenic Acid** at 100mg sits right at the top of its typical range. **Folate** at 400mcg meets the RDA, and **Riboflavin** at 26mg is well within the supplemental sweet spot.

The form choices are a mix. What this means for you: B6 and B2 include their active, body-ready forms alongside standard versions, which is a meaningful upgrade for absorption. However, **Thiamine** at 24mg uses hydrochloride — a budget form with lower bioavailability than benfotiamine.

The notable gap: there's no B12 in this formula. If you're relying on this as your only B complex, you'll need a separate B12 supplement, especially if you follow a plant-based diet.
