THORNE Basic B Complex is a 60-capsule B-vitamin supplement designed to support cellular energy, brain and nervous system function, with eight active-form B vitamins plus choline.
Basic B Complex is made for people looking for a single supplement that brings together the B vitamins and choline, with support for the body's energy processes and nervous system. Its formula focuses on functions B vitamins help maintain, rather than presenting the capsules as a source of immediate energy or a substitute for food.
Each capsule contains eight B vitamins—B1, B2, B3, B5, B6, B7, B9 and B12—along with choline. The nutrients are provided in active, tissue-ready forms, with the formula designed to enhance their bioavailability in the body. The 60-capsule supply gives you a defined count for planning your supplement routine.
B vitamins support the conversion of carbohydrates into fuel and the metabolism of fats and proteins, helping support cellular energy production and healthy red blood cell formation. These roles make the formula relevant to the body's everyday energy metabolism.
B vitamins serve as enzymatic cofactors that help make numerous brain neurotransmitters, supporting an optimally functioning nervous system, a healthy brain and nerve cells, and a healthy mindset. The formula is intended to support these functions, not to diagnose or treat a condition.
Thorne conducts four rounds of testing on every product in its laboratories, beginning with raw-material purity analysis and continuing through confirmation of finished-formula shelf life. The brand is trusted by more than 100 professional sports teams. A 2026 independent survey of U.S. supplement consumers and health-care practitioners ranked Thorne the #1 most recommended clinical brand.
THORNE Basic B Complex suits shoppers seeking a capsule formula that brings together all eight B vitamins and choline to support energy metabolism, brain and nervous system function. It provides 60 capsules with active-form B vitamins and a four-round testing process for each product.
