Niacinamide acts as a precursor to NAD/NADP coenzymes that participate in cellular energy reactions and redox balance.
Caution: High-dose niacinamide may cause flushing less often than niacin but can still cause digestive discomfort; take with food to reduce stomach upset.
Pantothenic acid forms part of coenzyme A, which is central to fatty acid metabolism and energy production.
Caution: Large doses may cause mild gastrointestinal upset; take with food if sensitive.
Vitamin B6 serves as a coenzyme in amino acid metabolism and neurotransmitter synthesis.
Caution: Very high intakes over time have been linked to sensory nerve discomfort; avoid combining multiple high‑dose B6 supplements.
Thiamine is converted to thiamine pyrophosphate, a coenzyme for carbohydrate metabolism and energy production.
Caution: Generally well tolerated; rare digestive upset may occur at high doses.
Riboflavin supports FAD and FMN coenzymes involved in mitochondrial energy production and antioxidant enzyme activity.
Caution: May turn urine bright yellow, which is harmless.
These B vitamins act as coenzymes across carbohydrate, fat and protein pathways, helping convert food into usable cellular energy. Niacinamide and riboflavin support redox reactions, while thiamine and pantothenic acid drive carbohydrate entry into the Krebs cycle; vitamin B6 supports amino acid and neurotransmitter metabolism.
