Vitamin B12 is one of the essential vitamins required for the function and development of various organs of the body such as the brain, nerves and blood cells. It is found in foods such as meat, fish, eggs and milk. However, there is another easy and quick way to get vitamin B12 and that is through supplements.
Supplements can be an easy way to get vitamin B12 but it is always advisable to consult a doctor before relying on such artificial sources. It is important to know the correct dosage of the dosage as per the requirements of your body. Only individuals who eat no dairy products, seafood and fortified cereals should use dietary supplements of vitamin B12.
Experts suggest that an overdose of vitamin B12 is very rare but can cause some side effects. Generally, people who take B12 injections are likely to experience adverse effects. The rate of absorption for these injections is said to be higher than for oral supplements and this is why they can cause negative effects. Therefore, the shot should be taken only if the doctor prescribes them.
Side effects of an overdose of vitamin B12:
Diarrhea, dizziness, skin rash, fatigue and swelling are some of the side effects of excessive intake of vitamin B12. An overdose of vitamin B12 in the body can also cause a rare but serious allergic reaction called anaphylaxis.
Studies show that B12 deficiency is more common in adults but if there is really a need for younger people then here is the right dosage.
For ages 14 and older, it is recommended that they should take 2.4 micrograms of B12 daily. While pregnant women should consume 2.6 micrograms, lactating women should take only 2.8 micrograms. Finally, for ages 50 and older, according to experts, 25 to 100 micrograms of B12 is sufficient.
