How to Choose the Right B12 Supplement
With so many options available, here’s what to consider when picking your B12 supplement:
Form Matters
Methylcobalamin is the active form your body uses directly. It’s ideal for most people, especially if you have digestive issues or are over 50. Cyanocobalamin is synthetic but well-researched and slightly more stable. Your body converts it to methylcobalamin, and it works perfectly well for most people. Adenosylcobalamin is another active form, though less common in supplements.
Delivery Method
Sublingual tablets and liquids bypass some of the digestive process, potentially improving absorption. Regular tablets work fine if your digestion is good. Sprays offer convenience and are great for people who dislike swallowing pills.
Dosage
Daily supplements typically range from 50-1000 mcg. Weekly high-dose options usually contain 1000-5000 mcg. More isn’t always better – your body can only absorb so much at once. For detailed guidance on B12 dosing, check out our complete B12 guide for vegan women.
Common Questions About B12 Supplements
When should I take my B12 supplement?
B12 can be taken any time of day, with or without food. Many people prefer taking it in the morning with breakfast to establish a routine. If you’re taking a sublingual form, avoid eating or drinking for 30 minutes afterward for best absorption.
How long before I notice results?
If you’re deficient, you might notice increased energy within 2-4 weeks. However, B12 works behind the scenes, and you might not “feel” anything even though it’s doing its job. Regular blood tests are the best way to monitor your levels.
Can I take too much B12?
B12 is water-soluble, so excess amounts are typically excreted in urine. There’s no established upper limit because toxicity is extremely rare. That said, stick to recommended doses unless working with a healthcare provider.
Do I need B12 if I eat fortified foods?
Fortified foods can contribute to your B12 intake, but supplements ensure consistency. It’s challenging to get adequate B12 from fortified foods alone unless you’re very deliberate about it. Most nutrition experts recommend supplementation for anyone following a fully plant-based diet.
