If you're looking for energy and nervous system support, the core B vitamins here are dosed right. **Thiamine**, **Riboflavin**, **Niacin**, **B6**, and **Pantothenic Acid** each deliver 100mg — landing right at the top of clinically studied ranges. That's a genuinely effective dose spread for the nutrients that drive energy metabolism.
The weak spots are **B12** at 100mcg and **Folate** at 400mcg of folic acid. B12 falls below the 250mcg minimum typically used in research, and folic acid is a synthetic form your body has to convert before it can use it. **Choline** at 20mg and **Inositol** at 100mg are included but well below their studied ranges — choline is at 20% of the clinical minimum and inositol at about 5%.
Form quality is the other consideration. B6 is delivered as pyridoxine rather than the active form, and B12 as cyanocobalamin rather than methylcobalamin. Your body can convert both, but it's extra work — and for B12, the dose is already low. If you mainly want B1 through B5 support, this delivers well for you.
