Thorne Basic B Complex - 60 Capsules
by Thorne
A premium B-complex supplement featuring all eight B vitamins in their bioactive, tissue-ready forms — including methylfolate (5-MTHF) instead of folic acid and methylcobalamin instead of cyanocobalamin. Thorne is one of the few supplement companies trusted by professional athletes and is NSF Certified for Sport. The capsule also includes choline citrate for additional methylation support. Particularly recommended for individuals with MTHFR gene variants who cannot efficiently convert synthetic B vitamins to their active forms.
AI Review Summary
Thorne Basic B Complex is the gold standard for bioactive B-vitamin supplementation, using tissue-ready forms throughout including methylfolate and methylcobalamin. The NSF Certified for Sport designation provides exceptional third-party quality assurance that few competitors match. Users with MTHFR variants and methylation concerns consistently report noticeable benefits. The main barrier is price — it costs significantly more than standard B complexes, and those without specific genetic or health needs may not benefit from the premium formulation.
Pros
- +All B vitamins in bioactive tissue-ready forms
- +NSF Certified for Sport — rigorous third-party testing
- +Includes choline for additional methylation support
- +Vegan-friendly cellulose capsules
Cons
- -Premium price — roughly double the cost of standard B complexes

Clean Label Analysis
While the capsule does contain some standard excipients like MCC and silicon dioxide, Thorne uses calcium laurate instead of the more common magnesium stearate, which some practitioners prefer. The leucine serves as a natural flow agent. Overall a cleaner-than-average formulation for a complex product.
