How it works
Thorne’s Vitamin B12 supplement delivers methylcobalamin, the most bioavailable and active form of vitamin B12, to support critical bodily functions such as cardiovascular health, nerve function, sleep regulation, and red blood cell formation. Unlike many B12 supplements that use cyanocobalamin, which requires conversion by the liver into an active form, Thorne provides methylcobalamin in its tissue-ready state. This means your body can immediately utilize it for essential metabolic processes without needing to detoxify or modify it first.
Methylcobalamin plays a vital role in maintaining healthy methylation—a key process for DNA repair, detoxification, and neurological health. It also supports the recycling of homocysteine, an amino acid associated with cardiovascular health when kept at optimal levels. Research indicates that methylcobalamin is retained in the liver more efficiently than cyanocobalamin, ensuring greater tissue accumulation and reduced urinary excretion. This enhanced bioavailability makes Thorne’s Vitamin B12 a superior choice for individuals seeking maximum benefit from their B12 supplementation.
Regular intake of methylcobalamin may also help regulate circadian rhythms, promoting better sleep and improved overall well-being. Thorne’s Vitamin B12 is rigorously tested and certified by third-party labs, guaranteeing that the product is free from harmful contaminants like heavy metals, pesticides, and microorganisms. Trust Thorne’s commitment to quality and innovation to deliver a clean, effective B12 supplement that supports your body’s most critical functions.
