In general, water-soluble vitamins, such as vitamins B1 to B9, B12 and C, are more likely to cause an immediate reaction, Ehrlich said. Fat-soluble vitamins, such as vitamins A, D, E, and K, are more likely to cause a delayed reaction in allergic contact dermatitis (ACD). Can vitamins cause a rash? The answer is yes, and these rashes may look different on each person. Yes, taking large amounts of vitamin 12 can cause a skin reaction in people who are sensitive to cobalt.
Symptoms include an itchy rash. Taking too much cholecalciferol over a long period of time can cause a skin rash. It can also cause high levels of calcium. Too much calcium in the body (hypercalcaemia) can cause stomach pain, weaken bones, and damage the kidneys and heart. Vitamin B6 deficiency is one of the causes of an itchy red rash called seborrheic dermatitis.
Topical vitamin C has many benefits for the skin, such as improving the texture and appearance of the skin and protecting it from the sun's harmful UV rays, according to Harvard Health Publishing. However, if you're diagnosed with an allergy to vitamin supplements (such as iron supplements or vitamin C), the most effective treatment is to avoid using that supplement and any product that contains the ingredient you're allergic to, according to the American College of Allergy, Asthma and Immunology (ACAAI). Vitamin B5 and its derivatives, widely used in pharmaceutical and cosmetic compounds, such as hair and skin conditioners 35, have been reported to be causative agents of ACD, ranging from classic localized eczematous lesions at the contact site 36 to generalized eczematous eruptions. This condition is called carotenemia and is characterized by yellow-orange skin discoloration, more intense in areas with thicker keratin, such as the palms of the hands and soles of the feet, or with more subcutaneous fat. To treat hives or skin rashes caused by vitamins, you can use an over-the-counter antihistamine and topical steroid-based cream or lotion, which should help ease swelling and itching.
While vitamin supplements can help you maintain your essential daily intake of vitamins and minerals, the onset of hives or any other complication after taking them can be an alarming sign. However, a lack of vitamin C can lead to skin disorders as a result of decreased collagen production. Try to maintain the recommended intake to avoid skin-related problems, such as skin rashes caused by excessive or insufficient intake of certain vitamins. Topical tanning products use carotene to cause skin discoloration called carotenodermia, which mimics a tan.
If you have a vitamin C deficiency, you may have symptoms of rough, dry, and bumpy skin, easy bruising, spoon-shaped nails with red spots, bright red patches on the skin around the hair follicles, bleeding gums, and wounds that don't heal. As part of his treatment plan, the chiropractor recommended daily administration of glucosamine and chondroitin supplements (1500 mg of glucosamine sulfate and 1200 mg of chondroitin sulfate) to help maintain joint cartilage and potentially reduce inflammation and pain. This example demonstrates the need to include late allergic reactions induced by supplements in follow-up when patients are recommended to take supplements and experience skin rashes or other suspicious reactions. You can also try a patch test, in which at first you only apply the serum to a small area of the skin to see if you have any reactions. An overdose of vitamin C does not usually cause a rash, hives, or other skin effects; rather, side effects include diarrhea, nausea, abdominal cramps, and flatulence.
Other skin reactions caused by vitamin B3 compounds include itching, dry skin, dermatitis, hives, mouth pain, dry hair and acanthosis nigricans.
