A complete complex of B vitamins with extra B5 for adrenal support and stress management. Healthy adrenal glands play an important role in effectively managing stress. Pantothenic acid (vitamin B5) is part of the B-vitamin complex and is essential for healthy adrenal and immune function. Thorne's Stress B-Complex provide extra vitamin B5, along with seven other water-soluble nutrients: thiamine (vitamin B1), riboflavin/R5P (vitamin B2), niacin (vitamin B3), pyridoxine/P5P (vitamin B6), methylcobalamin (vitamin B12), methyl-folate (5MTHF), and biotin. Although each B vitamin is chemically distinct, they work synergistically in various biochemical functions throughout the body – including cellular energy production, healthy red-blood-cell formation, and healthy neurological function. Most B vitamins, with the exception of vitamin B12, are not stored in the body; consequently, they must be acquired daily from the diet in order to maintain optimal health.
