Thiamin acts as a coenzyme in carbohydrate metabolism to help convert food into cellular energy and support nerve function.
Caution: High-dose B vitamins may cause mild digestive discomfort in some people; take with food if sensitive.
Riboflavin forms flavin coenzymes (FAD/FMN) that participate in energy production and antioxidant enzyme reactions.
Caution: May cause harmless bright yellow urine due to riboflavin excretion.
Niacinamide supports cellular energy pathways as a component of NAD/NADP without typically causing the flushing linked to nicotinic acid.
Caution: High amounts may cause digestive upset in some individuals; take with food if needed.
Vitamin B6 serves as a coenzyme in amino acid metabolism and neurotransmitter synthesis.
Caution: Very high chronic intakes of B6 have been associated with nerve tingling; follow suggested use unless advised otherwise.
Folate supports one‑carbon metabolism for DNA synthesis and methylation processes.
Caution: Folic acid can mask signs of low vitamin B12; this matters if dietary B12 intake is low.
Core B vitamins like thiamin, riboflavin, niacinamide, and pantothenic acid work across energy pathways to help convert carbohydrates, fats, and proteins into usable energy. Folate and B12 support methylation and red blood cell formation, while B6 contributes to amino acid metabolism and neurotransmitter synthesis for nervous system function.
Label Warning: Consult a health professional before use if you are pregnant, breastfeeding, trying to conceive, taking medication, have a medical condition, or anticipate surgery.
Who should be cautious: People on thyroid medications or certain antibiotics may need to separate dosing because this product contains calcium, which may affect absorption.
