Natural Factors Ultra S ActiveB Complex 60s

Ultra-Strength Active B Complex with full-spectrum coenzyme B vitamins from Natural Factors is a higher-strength formula than our regular Active B Complex. It offers even better coenzyme forms and includes BioPQQ® to enhance the action of B vitamins. This one-per-day, non-GMO formula is suitable for vegetarians and vegans and features Farm Fresh Factors, a bioenergetic blend of phytonutrients, for active support of energy metabolism.

Natural Factors BioCoenzymated™ Ultra Strength Active B Complex provides meaningful amounts of essential B vitamins in their most bioactive forms to help support energy metabolism, normal growth and development, and overall health. This one-per-day, non-GMO formula is suitable for vegetarians and vegans and features Farm Fresh Factors™, a bioenergetic blend of phytonutrients, for active support of energy metabolism.

Ultra Strength Active B Complex provides highly bioavailable coenzymated forms of folate, vitamins B1, B2, B3, B6, and B12, alongside pantothenic acid (B5), biotin, choline, inositol, and pyrroloquinoline quinone (PQQ) to support a wide array of physiological processes. PQQ is a natural antioxidant that protects against oxidative stress in mitochondria, the powerhouse of the cell. PQQ has also been seen to promote the creation of new mitochondria, with exciting implications for fighting the aging process.

A coenzyme is a naturally occurring compound that partners with specific enzymes to promote beneficial metabolic reactions in the body. Pre-formed coenzyme forms of B vitamins, such as Quatrefolic® (folate) and benfotiamine (B1), offer immediate, direct nutritional support, even for those with genetic differences that impair metabolism of standard B vitamins. Research has shown that Quatrefolic® can help increase blood folate levels up to three times more effectively than standard folic acid, while benfotiamine is 3.6 times more bioavailable than regular thiamine hydrochloride.

Natural Factors BioCoenzymated Ultra Strength Active B Complex is gluten-free, non-GMO, and suitable for vegetarians and vegans. This advanced formula is ideal for anyone who wants the highest quality, most bioactive forms of essential B vitamins.
