Product Information

Deficiency of thiamine can manifest as mental confusion, muscle weakness, indigestion, constipation, and other more serious conditions.* Causes for deficiency include malnutrition, genetic polymorphisms, and excessive consumption of caffeine and alcohol.

The B vitamins are essential for healthy nerve cell function &ndash especially thiamine, folate, and vitamin B12.*

Thorne's B-Complex #1 supplies 200 mg of thiamine HCl and the bioactive forms of the other B vitamins in each capsule to ensure you get the most bioavailable B-complex available.*

B-Complex #1 consists of a group of eight water-soluble compounds: thiamine (vitamin B1), riboflavin (vitamin B2), niacin (vitamin B3), pantothenic acid (vitamin B5), pyridoxine (vitamin B6), cobalamin (vitamin B12), folate, and biotin. Although each B vitamin is chemically distinct, they often work together in various biochemical functions throughout the body – from cellular energy production, to healthy red-blood-cell formation, to 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.*

Supplementing with active B vitamins is extremely important to everyone, especially individuals who may not be able to convert non-active vitamins to their active forms in the liver because of compromised liver function, poorly functioning enzymes, digestive disturbances, or age.* Dietary supplements containing these active cofactors have enhanced bioavailability, ensuring the body gets the nutrients it needs.*
