Stress B-Complex

Thorne’s Stress B-Complex delivers B vitamins in their active, tissue-ready forms, allowing the body to use them straightaway without converting them first. It includes methylated B12 and folate (5-MTHF), which are especially beneficial for individuals with gene mutations that affect nutrient absorption. With added choline to support brain and nervous system function, and no ingredients derived from yeast, it offers a clean and targeted formula. Taking this supplement helps you manage stress more effectively while supporting cognitive and neurological health.

Thorne sets the standard for excellence in the supplement industry. Recommended by over 100 professional sports teams and U.S. National Teams, Thorne offers a curated bundle of clean, science-backed supplements and treats designed to fuel your body naturally and effectively. With more than 30 years of dedication to quality, Thorne's commitment to purity and potency begins with sustainably sourced ingredients and rigorous testing. Every supplement undergoes four rounds of testing to ensure optimal absorption, safety, and efficacy, making Thorne the trusted choice for both health-conscious individuals and professionals.
