GLOSSARY

B-Complex Vitamins is a group of water-soluble vitamins with distinct metabolic roles; commercial mixtures need not reproduce natural food proportions.

B vitamins participate in varied metabolic and tissue pathways; B12 and folate also matter for cell division and blood formation. Membership does not imply identical functions or that one corrects another's deficiency. If an energy product contains caffeine or sugar, its immediate effect cannot simply be attributed to the B vitamins listed on the package.

Water solubility does not guarantee immediate harmless elimination of any excess. B12 can have substantial stores, while chronically high B6 intake is associated with nerve injury. Chemical grouping therefore cannot replace a safety assessment. Storage, saturable absorption and adverse effects need consideration for each member rather than treating the whole group as risk-free.

A varied food pattern is more useful than reliance on one food or capsule. Fruit, vegetables, grains, pulses, dairy or fortified alternatives and protein foods make different contributions. Long-term exclusions, very low energy intake, travel and restricted access can create gaps in sports diets; food records help identify which sources are actually missing.
