Pantothenic acid forms part of coenzyme A, which helps convert fats, carbohydrates, and proteins into cellular energy.
Caution: High doses may cause mild digestive upset in some people; take with food to reduce discomfort.
Vitamin B6 acts as a coenzyme in amino acid metabolism and neurotransmitter synthesis.
Caution: Very high intakes over time may be associated with tingling or numbness; follow the suggested use.
Niacin supports cellular energy production by forming NAD and NADP coenzymes used in metabolic reactions.
Caution: Niacin may cause temporary flushing, warmth, or itching; taking with food may lessen this effect.
L-5-MTHF is the active folate form that donates methyl groups for DNA synthesis and homocysteine metabolism.
Caution: Folate can mask low vitamin B12 status on some lab tests; consistent intake of B12 alongside folate is important.
Methylcobalamin supports methylation and helps convert homocysteine to methionine for cellular energy and nervous system function.
Caution: A small number of people may experience mild stimulation; consider taking earlier in the day if sensitive.
This formula pairs high-potency energy metabolism cofactors like pantothenic acid, niacin, and vitamin B6 to feed major cellular pathways for converting food into energy. Active folate (L-5-MTHF) and methylcobalamin B12 work together in methylation processes that support homocysteine metabolism and cellular function.
Label Warning: Temporary flushing, itching, rash, or gastric disturbances may occur. Do not exceed the recommended dose. Consult a physician if you are undergoing treatment for a medical condition or if you are pregnant or lactating.
Who should be cautious: People with sensitivity to niacin may be more likely to experience flushing or itching. Those on medications or with existing health conditions should discuss use with a healthcare provider before starting.
Storage: Store tightly closed in a cool, dry place.
