Nickel is a mineral. It is found in several foods including nuts, dried beans and peas, soybeans, grains, and chocolate. The body needs nickel, but in very small amounts. Nickel is a common trace element in multiple vitamins.
Nickel is used for increasing iron absorption, preventing iron-poor blood (anemia), and treating weak bones (osteoporosis).
How it works
Nickel is an essential nutrient in some chemical processes in the body. Its precise functions in the body are not known.
Likely EffectivePreventing nickel levels in the body from getting too low (nickel deficiency)
Nickel deficiency has not been reported in people, although it may exist, since nickel deficiency has been seen in animals. Taking trace amounts of nickel in a supplement is effective for preventing nickel deficiency.
Nickel is LIKELY SAFE for most adults when taken by mouth in amounts up to 1 mg/day
Taking more than 1 mg/day is POSSIBLY UNSAFE. Taking amounts slightly above the 1 mg/day level increases the chances of unwanted side effects. High doses are poisonous.Workers who have been exposed to nickel on the job over an extended period of time can develop allergies, lung disorders, and cancer.
Pregnancy and breast-feeding: Nickel isLIKELY SAFEinpregnantorbreast-feeding adult women when taken by mouth in doses less than the tolerable upper intake level (UL) of 1 mg/day. The safety of higher doses is unknown.Are there any interactions with medications?
Children: Nickel is LIKELY SAFE in children in daily doses less than the tolerable upper intake level (UL) of 0.2 mg/day in children 1 to 3 years, 0.3 mg/day in children 4 to 8 years, and 0.6 mg/day in children 9 to 13 years. Taking higher doses is POSSIBLY UNSAFE.
Kidney disease: People with kidney disease may not be able to tolerate nickel as well as other people. It's best to avoid nickel supplements if you have kidney problems.
Nickel allergy: People who are sensitive to nickel, including those with a history of skin rash after contact with nickel-containing jewelry, coins, stainless steel items, surgical implants, or dental appliances, can develop allergic reactions to nickel taken by mouth. These people should not take nickel supplements.
Disulfiram (Antabuse) might decrease how much nickel your body absorbs, making nickel supplements less effective.
