Vitamin B12

B12 deficiency is one of the most common and underdiagnosed nutritional deficiencies in the world. It affects an estimated 6% of adults under 60 and up to 20% of those over 60, with even higher rates among vegetarians and vegans (since B12 is found almost exclusively in animal products). The symptoms creep up slowly: fatigue, brain fog, mood changes, tingling in the hands and feet — often attributed to "just getting older."

B12 is essential for producing red blood cells that carry oxygen throughout your body. Without enough B12, you produce fewer (and abnormally large) red blood cells, leading to megaloblastic anemia and the persistent fatigue that comes with it. It's also critical for myelin production — the protective sheath around your nerves that ensures rapid, accurate signal transmission.

We use Methylcobalamin, the active form of B12 that your body can use immediately. Standard supplements often use cyanocobalamin, which must be converted to methylcobalamin before your body can use it — a process that doesn't work efficiently for everyone. At 1,000mcg, this provides a meaningful dose that supports optimal levels even in those with absorption challenges.
