How much B12 per day should you take for weight loss?

There is no established daily B12 dose for weight loss. The adult dietary requirement concerns nutritional adequacy, not a fat-loss prescription. If your B12 is low, a clinician usually chooses the dose and form. Raising either to pursue a scale change is not usually advised.

Does a vegan diet automatically mean I need injections?

No. A vegan eating pattern requires reliable B12 provision, but the form depends on individual assessment. Discuss fortified foods, supplements, and any testing needs with a qualified professional. Injections are not automatically required by a dietary label ( 1 ).

Can medicines affect B12 levels?

Yes, some long-term medicines can affect B12 levels. Talk to the clinician who prescribed the medicine before changing anything. They can consider B12 alongside the reason for that medicine ( 1 ).

What happens if you take B12 every day?

Daily vitamin B 1 2 supplements may help meet an identified nutritional need, but taking vitamin B12 every day does not establish a weight-loss benefit. Many people follow the label dose or the one their clinician advises. Review medicines and all supplement ingredients with a clinician or pharmacist because interactions and individual circumstances matter (1).

Which vitamin should I buy for weight loss instead?

There is no universal vitamin purchase that replaces a structured weight-management plan. Supplements are usually chosen for an identified need. Weight-loss supplement claims often exceed the evidence, and some products can cause harm or interact with medicines ( 4 ).
