Thiamin acts as a coenzyme in carbohydrate metabolism, helping enzymes convert food into cellular energy in the form of ATP.
Caution: High-potency B vitamins may cause mild stomach upset; take with food if sensitive.
Niacin forms NAD and NADP, which carry electrons in energy-producing reactions and support cellular metabolism.
Caution: Niacin may cause flushing and warmth, especially on an empty stomach.
Methylcobalamin supports methylation and helps convert homocysteine to methionine, which is important for energy metabolism and nervous system function.
Caution: Very high B12 intakes are generally well tolerated but may interfere with some lab tests; separate from testing when advised.
L-5-MTHF is the active folate form that supports methylation and nucleotide synthesis for red blood cells and nervous system function.
Caution: Folate works with B12; inadequate B12 status while taking high folate may mask B12-related issues.
Pyridoxal 5'-phosphate serves as a coenzyme in amino acid metabolism and neurotransmitter synthesis.
Caution: Very high doses of B6 over time may cause tingling or numbness; do not exceed suggested use.
Active forms of B6 (P5P), folate (L-5-MTHF), and B12 (methylcobalamin) work together in methylation and amino acid metabolism, supporting nervous system function. Thiamin and niacin feed energy pathways by assisting enzymes that convert carbohydrates and fats into ATP.
Label Warning: If pregnant, consult a health-care practitioner before use.
Who should be cautious: People with vitamin B–related sensitivities or on medications influenced by high-dose niacin or vitamin B6 may wish to discuss use with a healthcare provider before starting.
