Doctor’s Best Fully Active Folate 800 delivers 800 mcg of folate per capsule using Quatrefolic®, a patented form providing (6S)-5-Methyltetrahydrofolic acid — the biologically active form of folate that the body can utilise directly. Unlike synthetic folic acid, which requires enzymatic conversion in the body, Quatrefolic® supplies the metabolically ready form, making it a highly regarded choice for those seeking a premium folate supplement.

Each serving provides 400% of the Nutrient Reference Value for folate in a convenient single veggie capsule. The formula is vegan-friendly, gluten free, and free from GMOs, making it a clean and straightforward option for everyday nutritional support.
