Thiamine is converted to thiamine pyrophosphate, a coenzyme that helps enzymes turn carbohydrates into cellular energy and supports nerve signalling.
Caution: High-dose B vitamins may cause mild stomach upset; take with food to reduce discomfort.
Riboflavin forms FAD and FMN coenzymes that help enzymes produce energy in mitochondria and regenerate antioxidants.
Caution: May cause bright yellow urine due to natural pigment, which is harmless.
Niacinamide supports NAD/NADP coenzyme formation that participates in energy metabolism and cellular repair processes.
Caution: Niacinamide is less likely to cause flushing than niacin, but taking with food may improve tolerance.
Vitamin B-6 is converted to PLP, a coenzyme involved in amino acid metabolism and neurotransmitter synthesis.
Caution: Long-term very high intakes of B-6 have been linked with nerve tingling; follow the suggested use.
Folic acid supports one-carbon metabolism for DNA synthesis and helps recycle homocysteine via methylation pathways.
Caution: Folic acid may mask signs of low vitamin B-12; adequate B-12 intake is important, especially for vegans and vegetarians.
Core B vitamins supply coenzymes that drive carbohydrate, fat and protein metabolism for cellular energy. Folate and B-6 contribute methylation functions that work alongside B-12 to manage homocysteine pathways and support nervous system function.
Label Warning: For adults only. Consult a physician if pregnant or nursing, taking medication, or with a medical condition. Contains biotin which may interfere with some blood test results. Natural colour variation may occur.

B-50 Tabs provide a full complement of B-vitamins plus choline and inositol. These vitamins work to support energy production, maintain healthy homocysteine metabolism, and promote the health of the nervous system. B-vitamins are water soluble, and with the exception of B-12, have limited storage in the body and thus require daily replenishment. While B-12 is stored in the liver, dietary sources are of animal origin only (meat and dairy) and supplementation with B-12 may be especially important for vegetarians.
Take 1 tablet daily with a meal.
