Thorne Vitamin B12 1 mg — the standard methyl-B12 dose in a clean capsule
One capsule gives you 1,000 mcg (1 mg) of methylcobalamin, the active, tissue-ready form of vitamin B12 that the body uses directly in its methylation pathways. 1,000 mcg is the dose I start most people on because it adjusts so easily: one capsule a day for maintenance, two a day for 2,000 mcg, up to three if your practitioner directs it.
Who I reach for it with: vegetarians and vegans; adults over 50 and anyone with low stomach acid or on acid-blocking medication, since those groups absorb B12 from food poorly; people on metformin; fatigue and brain-fog workups; methylation and homocysteine protocols alongside active folate.
What makes it different: nothing in the capsule but methylcobalamin, a cellulose capsule, leucine, microcrystalline cellulose and silicon dioxide. Free from gluten, dairy and soy, and third-party tested by Thorne for purity and label accuracy.
Protocol fit: pairs with Thorne 5-MTHF 1 mg for methylation support. Prefer a liquid you can dose by the drop? Apex Vitamin B12 (K34) and B12-Max (K56). Prefer a larger bottle? Pure Encapsulations Methylcobalamin comes in 180 capsules. Designs for Health Vitamin B12 is a 5,000 mcg lozenge.
FAQ — Why methylcobalamin instead of cyanocobalamin? Methylcobalamin is already in the active form the body uses, so there's no conversion step. It's the form I recommend.
FAQ — Capsule, liquid or lozenge? Once you're taking methylcobalamin at the right amount, B12 products are fairly interchangeable. Choose the form you'll actually take every day.
