One of the important vitamins, vitamin B12 is necessary for the growth and operation of many different bodily organs, including the brain, neurons, and blood cells.

Foods including meat, fish, eggs, and milk, among others, contain it. Supplements are a different quick and simple approach to obtaining vitamin B12, though.

It may be simple to obtain vitamin B12 through supplements, but it’s always good to speak with a doctor before relying on such artificial sources.

It’s crucial to understand the proper supplement dosages to consume based on your body’s needs. Only people who don’t consume dairy, shellfish, or fortified cereals should take vitamin B12 supplements.

Although vitamin B12 overdose is extremely uncommon, it may have certain negative consequences. B12 injection users are often more likely to have negative side effects.

These injections are reported to have a faster rate of absorption than oral supplements, which is why they could have unfavorable effects. As a result, the injections must only be administered as directed by a physician.


The negative consequences of consuming too much vitamin B12 include diarrhea, lightheadedness, skin rashes, exhaustion, and edema.

Anaphylaxis is an uncommon but life-threatening allergic response that can occur as a result of an excess of vitamin B12 in the body.

According to studies, adults are more likely to have a B12 deficit than children, but if there is a requirement for children, this is the recommended dosage.

It is advised that people take 2.4 micrograms of B12 daily starting at the age of 14. While breastfeeding mothers should only consume 2.8 micrograms, pregnant women should consume 2.6 micrograms.

Finally, specialists say that 25 to 100 micrograms of B12 daily are adequate for those 50 years of age and older.
