About Doctor’s Best – Fully Active B-Complex with Quatrefolic – 60 vcaps
Doctor’s Best Fully Active B-Complex with Quatrefolic delivers a comprehensive spectrum of B vitamins in their most bioavailable, coenzyme-active forms. Rather than relying solely on standard precursor forms, this formula includes riboflavin-5-phosphate, pyridoxal-5-phosphate, and methylcobalamin — forms that the body can utilise directly without requiring conversion steps. Folate is supplied as Quatrefolic®, a patented (6S)-5-methyltetrahydrofolic acid glucosamine salt, widely regarded as one of the most advanced and bioavailable folate sources available.
Each capsule also provides Vitamin C alongside pantothenic acid, biotin, niacin, and thiamin at meaningful levels. B vitamins contribute to normal energy-yielding metabolism, normal functioning of the nervous system, normal psychological function, and the reduction of tiredness and fatigue — all within a single convenient daily capsule.
Formulated with a clean excipient profile and enclosed in a hypromellose vegetarian capsule, this product is suitable for vegans and vegetarians. It is free from gluten, GMOs, and soy, making it a trustworthy choice for those seeking a high-quality, fully active B-complex supplement.
