Thorne Research Stress B-Complex (60 Capsules)

SKU: TH00035

Complete B vitamin complex with extra B5 for adrenal support

What It Does

Thorne Stress B-Complex delivers complete B vitamin support with extra B5 specifically for adrenal function. Unlike basic B complexes, this formula provides 250mg of pantothenic acid — the B vitamin your adrenals need most during stress. The complete spectrum works together to support natural energy production and nervous system function.

Why It Works

EXTRA ADRENAL SUPPORT: 250mg pantothenic acid targets the specific B vitamin your stress response system demands most.
BIOACTIVE FORMS: Methylcobalamin B12 and 5-MTHF folate work immediately — no conversion required unlike cheaper forms.
COMPLETE SPECTRUM: All eight B vitamins in therapeutic amounts support energy pathways and neurotransmitter production.

What's Inside

Clean formula with bioavailable nutrient forms. Hypromellose capsules from plant cellulose. Third-party tested for purity and potency. NPN N/A.

Why we carry it: Thorne's pharmaceutical manufacturing standards deliver the bioavailable forms serious health-conscious customers demand.
