Energy metabolism, nervous system support, homocysteine metabolism
Adults with busy schedules seeking daily energy metabolism support or those with limited dietary variety who want a broad B-complex.
Take 1 tablet once daily with a meal; the sustained release design may be gentler on the stomach and supports gradual nutrient release.
Non-GMO; Vegetarian/Vegan; Kosher; Not manufactured with wheat, gluten, soy, milk, egg, fish, shellfish, tree nut or sesame ingredients; Produced in a GMP facility that processes other allergens.
Thiamin is converted to thiamin pyrophosphate, a coenzyme that helps enzymes convert carbohydrates into energy and supports normal nerve signalling.
Caution: High-dose B1 is generally well tolerated, but take with food if you experience stomach upset.
Riboflavin forms FAD and FMN coenzymes that help drive cellular energy production and redox reactions.
Caution: May cause bright yellow urine, which is harmless.
Niacinamide supports the formation of NAD+/NADP+, key cofactors for metabolic reactions and cellular energy processes.
Caution: Unlike niacin, niacinamide is less likely to cause flushing, but high intakes may cause digestive discomfort in some people.
Vitamin B6 is converted to PLP, a coenzyme that supports amino acid metabolism and the formation of neurotransmitters.
Caution: Very high chronic intakes of B6 have been associated with sensory nerve effects; follow the suggested use unless advised otherwise.
Folate donates one-carbon units needed for DNA synthesis and supports homocysteine metabolism.
Caution: Folic acid may mask signs of low vitamin B12 status; those with limited B12 intake should ensure adequate B12.
Core B vitamins B1, B2, B3 and B6 act as enzyme cofactors that help convert carbohydrates, fats and proteins into usable cellular energy. Folate and B6 support methylation and homocysteine metabolism, complementing the energy pathways with one-carbon transfer functions. Added choline and inositol further assist lipid metabolism and cell membrane function.
Label Warning: For adults only. Consult a physician if pregnant or nursing, taking medication, or if you have a medical condition. Contains biotin which may interfere with some blood test results. Designed for extended release.
Who should be cautious: People scheduled for lab tests, especially thyroid or cardiac markers, due to possible biotin interference. Those with sensitivities to niacin may experience flushing. If you take medications that may interact with high-dose B vitamins or biotin, discuss with a healthcare provider before use.
Storage: Store in a cool, dry place after opening.

B-100 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.
Hypromellose (cellulose), microcrystalline cellulose stearic acid (vegetable source), vegetarian coating and silicon dioxide.
Made and quality tested in the USA with globally sourced ingredients.
