Energy metabolism, nervous system support, red blood cell formation
Adults with busy schedules who want convenient daily B vitamin intake or those with limited dietary variety seeking extra support for energy metabolism.
Adults take 1 tablet once daily with any meal; prolonged-release tablets are often better taken with food and a full glass of water. Avoid exceeding the suggested serving, and consider spacing away from other high-dose B-complexes.
Gluten-free; Non-GMO; No added sugar, yeast, preservatives, artificial flavours or colours.
Thiamine is converted to thiamine pyrophosphate, a coenzyme that helps enzymes convert carbohydrates into cellular energy and supports normal nerve function.
Caution: High-dose B1 is generally well tolerated, but take with food if sensitive to vitamins to reduce stomach discomfort.
Riboflavin forms FAD and FMN coenzymes that help enzymes produce cellular energy and support antioxidant enzyme activity.
Caution: May cause bright yellow urine due to riboflavin metabolites, which is harmless.
Niacinamide supports energy metabolism as part of NAD and NADP coenzymes used in hundreds of cellular reactions.
Caution: Niacinamide usually does not cause flushing, but high doses may cause stomach upset in some people; take with food.
Vitamin B6 is converted to PLP, a coenzyme involved in amino acid metabolism and neurotransmitter synthesis.
Caution: Very high chronic intakes of B6 have been linked to nerve tingling; follow the suggested use and avoid combining with other high-dose B6 products.
Folate is reduced to active tetrahydrofolate forms that carry one-carbon units for DNA synthesis and amino acid metabolism.
Caution: Folic acid can mask low vitamin B12 status; those with low B12 intake should be mindful of overall B12 nutrition.
These B vitamins work across energy pathways: B1, B2, niacinamide and B5 drive carbohydrate, fat and protein metabolism, while B6 and folate support amino acid processing and neurotransmitter production. Together they help sustain cellular energy reactions while supporting healthy red blood cell formation and nervous system function.
Label Warning: Consult a healthcare provider before use if you are pregnant, nursing, taking medicines, have a medical condition or are planning a medical procedure. Stop use and contact a physician if adverse reactions occur. Do not exceed the recommended dosage. Individual results may vary.
