Side Effects of Taking Too Much Vitamin B12
While vitamin B12 is generally safe and non-toxic, taking too much of it can cause several side effects. Here are some of the side effects of taking too much vitamin B12:
1. Acne
Taking too much vitamin B12 can cause acne breakouts. This is because vitamin B12 can increase the production of sebum, which is the oil that our skin produces. Excess sebum can clog the pores and lead to acne.
2. Headaches
Excessive intake of vitamin B12 can cause headaches. This is because vitamin B12 can cause blood vessels to dilate, which can lead to headaches.
3. Nausea and Vomiting
Taking too much vitamin B12 can cause nausea and vomiting. This is because vitamin B12 can irritate the stomach lining and cause gastrointestinal problems.
4. Diarrhea
Excessive intake of vitamin B12 can cause diarrhea. This is because vitamin B12 can interfere with the absorption of other nutrients in the digestive system.
5. Skin Rash
Taking too much vitamin B12 can cause skin rashes. This is because vitamin B12 can cause an allergic reaction in some people.
6. Anxiety
Excessive intake of vitamin B12 can cause anxiety. This is because vitamin B12 can stimulate the nervous system and cause hyperactivity.
7. Insomnia
Taking too much vitamin B12 can cause insomnia. This is because vitamin B12 can interfere with the production of melatonin, which is the hormone that regulates sleep.
8. High Blood Pressure
Excessive intake of vitamin B12 can cause high blood pressure. This is because vitamin B12 can cause blood vessels to constrict, which can increase blood pressure.
Conclusion
Vitamin B12 is an essential nutrient that our body needs to function properly. However, taking too much of it can have adverse effects on our health. If you are taking vitamin B12 supplements, make sure to follow the recommended daily intake to avoid any side effects.
