Doctor’s Best Fully Active B-Complex with Quatrefolic delivers a comprehensive blend of all eight essential B vitamins, formulated in their most bioavailable and metabolically active forms. By combining coenzymated forms such as riboflavin-5-phosphate, pyridoxal-5-phosphate, methylcobalamin, and the patented Quatrefolic® folate ((6S)-5-methyltetrahydrofolic acid, glucosamine salt), this formula is designed to support optimal nutrient uptake without requiring conversion by the body.

The inclusion of Quatrefolic®, a fourth-generation folate source, provides the biologically active form of folic acid that the body can utilise directly, making it an excellent choice for individuals seeking enhanced folate support.

Each serving provides meaningful amounts of Vitamin C alongside the full B-vitamin spectrum, all enclosed in a plant-based veggie capsule. With no GMOs, gluten, soy or animal-derived ingredients, this formula is suitable for vegans and vegetarians looking to support their daily nutritional intake.
