Thorne’s Stress B-Complex is your go-to for nutritional support when life gets busy. This expertly balanced blend features all eight essential B vitamins—including extra pantothenic acid (B5)—plus choline, to help you feel your best every day. B vitamins such as thiamin, riboflavin, niacin, B6, folate, B12, biotin, and pantothenic acid work together to support energy-yielding metabolism, normal psychological function, and the reduction of tiredness and fatigue. Pantothenic acid also contributes to normal mental performance, while choline supports normal lipid metabolism. Whether you’re tackling a full schedule or just want to feel more balanced, Stress B-Complex is designed to help you thrive.

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.
