Thorne B-Complex #12, 60 Capsules
UPC: 693749112037
Thorne's B-Complex #12 is a comprehensive B-vitamin supplement formulated to support energy production, red blood cell formation, and neurological function. It includes all eight B vitamins, with notable emphasis on active, methylated forms: folate as L-5-MTHF and vitamin B12 as methylcobalamin, which are intended to benefit individuals with MTHFR gene variants or those who may have difficulty converting standard forms. The formula also provides choline and uses a blend of standard and activated forms for vitamins B2 and B6.
This product differentiates itself by focusing on tissue-ready, bioavailable forms of key nutrients, avoiding yeast-derived ingredients, and undergoing third-party testing for label accuracy and contaminant screening. According to Thorne, it is designed for aging individuals, those on medications that deplete B-vitamins, or anyone seeking nervous system support. It is manufactured in the USA and comes in a 60-capsule package with a gluten-free certification.
