THORNE Stress B-Complex is a scientifically formulated B-vitamin complex with eight active B vitamins and choline designed to support energy metabolism, nervous system function, and the body's response to everyday stressors.

This formula provides eight tissue-ready B vitamins with extra pantothenic acid (B5) and added choline, delivered in a daily capsule intended to support cellular energy production, neurotransmitter pathways, and healthy adrenal function.

How does this B-complex help when I'm feeling run down?

THORNE's formula supplies active forms of B vitamins that participate in energy-producing reactions inside cells. By supporting enzymatic processes involved in converting food to usable energy, the blend helps maintain normal energy metabolism during busy periods.

• Contains eight active B vitamins to support cellular energy pathways
• Extra vitamin B5 (pantothenic acid) included for adrenal nutrient support
• Choline helps with methylation and neurotransmitter precursors

Will these capsules support focus and cognitive balance?

• Active vitamin forms improve tissue availability versus some inactive forms
