10. Anaphylaxis
Another serious side effect of vitamin B12 is Anaphylaxis. Allergies are mostly not dangerous and cause mild symptoms like rashes, eye irritation, and sneezing. However, for some people, their allergies can be deadly for them. Sometimes, the reaction is so severe and will lead to a condition known as the anaphylaxis.
Anaphylaxis can lead to severe swelling, itchiness, and difficulty in breathing. This can possibly happen to people who are allergic to Vitamin B12. Unfortunately, some people are not even aware that they are allergic to certain supplements. So if you noticed allergic reactions in your body after taking the vitamin B12 supplements, you should cease the supplementation immediately before it leads to anaphylaxis.
