B-Complex #6

Thorne B-Complex #6 is a balanced B vitamin formula with added vitamin B6, designed to support cellular energy metabolism, amino acid processing, and mood balance — making it a practical daily supplement for athletes, fitness enthusiasts, and active women.

B vitamins are essential to energy production, red blood cell formation, detoxification, and hundreds of biochemical pathways in the body.

INTERACTIONS

5-methyltetrahydrofolate (5-MTHF) supplementation is not recommended concurrent with methotrexate cancer therapy, as it can interfere with methotrexate's anti-neoplastic activity; however, this folate source has not been shown to interfere with the anti-inflammatory activity of methotrexate. An individual taking methotrexate for psoriasis or rheumatoid arthritis can safely take a supplement containing folate.

Doses of vitamin B6 above 200 mg may inhibit breast milk production.

Frequently Asked Questions

What makes Thorne B-Complex #6 different from a standard B-complex supplement?

It is designed for athletes, fitness enthusiasts, and active women who want daily B vitamin support — particularly those seeking help with energy metabolism, muscle recovery routines, or nutrient replenishment.
