Energy metabolism support; Nutrient conversion and methylation; Red blood cell formation
Adults with busy schedules who want convenient daily B vitamin support or people with limited dietary variety seeking active B forms.
Take 1 capsule 1 to 3 times daily with food; swallow whole without crushing. B vitamins are often better tolerated with meals.
Vegan; Non-GMO; Gluten Free; Contains: Corn
Niacin is converted to NAD/NADP coenzymes that drive cellular energy reactions and redox balance.
Caution: May cause flushing or warmth; taking with food and spacing doses may reduce discomfort.
Benfotiamine is a fat-soluble thiamine derivative that supports carbohydrate metabolism and helps form thiamine-dependent enzymes for energy production.
Caution: High doses may interact with certain medications; follow label directions and consult a professional if unsure.
Pyridoxal-5-phosphate is the active B6 coenzyme that supports amino acid metabolism and neurotransmitter synthesis.
Caution: Very high intakes over time may be associated with nerve tingling; use as directed.
Methylcobalamin acts as a cofactor for methylation and energy metabolism, supporting red blood cell formation.
Caution: Very high B12 may mask low folate status on some labs; those with B12-related testing should inform their provider.
L-5-MTHF is the bioactive folate form that donates methyl groups for homocysteine metabolism and DNA synthesis.
Caution: High folate intake may interact with certain medications; consult a professional if pregnant or using prescription drugs.
Active B vitamins provide ready-to-use coenzyme forms that feed into energy metabolism and methylation pathways. Benfotiamine and niacin support carbohydrate and redox reactions, while P-5-P, methylcobalamin, and L-5-MTHF provide methyl and amino acid processing support that works across interconnected nutrient cycles.
Label Warning: Consult a physician before use if you are pregnant, nursing, have a medical condition, or are taking any medication.
Who should be cautious: People with corn allergies, since the product contains corn. Individuals sensitive to high-dose niacin or vitamin B6 may prefer to review dosing with a healthcare provider.
