About Thorne - Vitamin B12 (formerly known as Methylcobalamin) 90 capsules

Thorne's Vitamin B12 delivers methylcobalamin, the bioactive, coenzyme form of B12 that the body can utilize directly without conversion. This formulation supports neurological function, red blood cell production, and healthy homocysteine metabolism, making it a practical option for those with methylation challenges, vegetarians, vegans, or anyone seeking to maintain B12 status.

Why It's Worth Considering: Thorne uses methylcobalamin rather than the cheaper cyanocobalamin form, encapsulated without unnecessary excipients, consistent with the manufacturing standards Thorne is known for in practitioner settings.
