Nature Made Super B-Complex covers all eight B vitamins to support everyday energy metabolism, the process your body uses to turn food into usable energy, and it leads with a full 100mg of **thiamine** (B1) right at the top of its typical supplement range. Several of the other B vitamins, though, land closer to basic daily-requirement levels than the higher doses used in targeted research, so this is dependable everyday coverage rather than a high-potency formula.
**Riboflavin** (20mg) and **niacin** (25mg) are dosed well enough to contribute meaningfully, and you also get 150mg of added **vitamin C**. The B vitamins here use standard synthetic forms, which your body absorbs and uses fine if you are generally healthy.
Where it thins out is the rest of the panel: vitamin B6 (2mg), B12 (15mcg), and pantothenic acid (5.5mg) cover daily needs but fall short of the larger doses some people look for. One thing worth knowing is that the 400mcg of **folate** is folic acid, the synthetic form that people with an MTHFR gene variant convert less efficiently than active methylfolate.
