While vitamin B12 supplementation is a great solution for most people, there are a few people who either shouldn’t take it at all or who might have an adverse reaction to it.
While some people may have a sensitivity to vitamin B-12, it is very unlikely. However, if you are sensitive the most common side effects are
- your skin is itchy
- you develop a rash
- you have mild, quickly passing diarrhea
- you’re mildly nauseous
Much rarer side effects include
- pores or hair follicles get red and inflamed (inflammatory acne or folliculitis), usually on the face or near the area the patch is applied
- a feeling of swelling of the entire body
- back pain
People who are actually allergic to cobalamin/ cyanocobalamin or cobalt obviously should avoid vitamin B-12 supplementation without consulting with their doctor. However, this allergy is extremely rare. Even so, Healthy Habits’ Transdermal Vitamin B-12 Patches use only the best form of B-12, high quality methylcobalamin. Most supplements use hard to digest and absorb cobalamin/ cyanocobalamin – be sure to read your labels!
