Ingredients explained
Vitamin C (ascorbic acid)
Functions as an antioxidant and cofactor for collagen and carnitine synthesis, helping protect cells from oxidative stress and support connective tissue formation.
Caution: High doses may cause stomach discomfort for some people; taking with food may improve tolerance.
Niacinamide (vitamin B3)
Acts as a precursor to NAD+/NADP+, which are needed for cellular energy metabolism and redox reactions.
Caution: May cause mild digestive upset in some individuals; take with food if sensitive.
Thiamin (vitamin B1 as thiamin mononitrate)
Serves as a coenzyme (TPP) in carbohydrate metabolism to help convert food into energy.
Caution: Very high intakes are usually well tolerated but may cause mild digestive discomfort in some people.
Riboflavin (vitamin B2)
Functions as FAD and FMN coenzymes in energy production and antioxidant pathways.
Caution: Can turn urine bright yellow, which is harmless.
Vitamin B6 (pyridoxine HCl)
Acts as PLP coenzyme in amino acid metabolism and neurotransmitter synthesis.
Caution: Very high chronic intakes may affect nerve function; follow label directions.
How they work together
B vitamins provide coenzymes that participate in carbohydrate, fat, and protein metabolism, working across shared energy pathways. Vitamin C adds antioxidant activity and supports connective tissue enzymes, complementing the metabolic roles of the B complex.
Safety and tips

Who should be cautious: People who need to limit calcium or who take thyroid medications or certain antibiotics may need spacing from calcium-containing products.
