Vitamins for Cognitive Performance

Not exactly. Caffeine provides a temporary stimulant effect, while vitamins support your body’s natural energy production systems. Nutrients like B vitamins, iron, and magnesium help convert the food you eat into usable cellular energy. They don’t give an instant “boost,” but they help maintain steady vitality over time.

Some of the most recognized nutrients include B-complex vitamins (especially B12, B6, and thiamine), iron, magnesium, vitamin C, and CoQ10. These nutrients are involved in metabolism, oxygen delivery, and mitochondrial function — all key to maintaining healthy energy levels.
