Potential Benefits: Although nickel-specific enzymes have yet to be identified in higher animals, nickel can activate or inhibit a number of enzymes that usually contain other elements.

The production or action of some hormones (prolactin, adrenaline, nor adrenaline, aldosterone) responds to changes in nickel concentration. Within cells, nickel alters membrane properties and influences oxidation/reduction systems.

Nickel has great affinity for cellular structures such as chromosomes and ion channels, but its influence on them at normal tissue concentrations isn’t known.

Description: Nickel is an essential nutrient for higher animals. Although a number of cellular effects of nickel have been documented, a deficiency disease has not been described in man.

Nickel is found in highest concentrations in lung, kidney and some hormone-producing tissues.


Potential Side Effects: Food nickel rarely has any side effects, but there are many allergies associated with nickel worn as jewelry and other metallic items.

Potential Interaction: Skin reactions such as itching, burning, redness or other rashes are the most common symptoms with nickel sensitivity, however asthma attacks are another, but less frequent possibility in some people. Some overweight people have higher levels of nickel, but it may be down to high chocolate consumption.

Intestinal absorption of nickel is less than 10%, with the kidneys controlling the retention or elimination of nickel, however most of it is eliminated in faeces, some in urine, and a small amount through sweat. May have a reaction with Vitamin E but is not related to the antioxidative properties of Vitamin C

General Usage: May be taken daily.

Food Sources: Almonds, Buckwheat Seeds, Chocolate, Cocoa, Hazelnuts, Jellied Herring, Lentils, Oats, Oysters, Potatoes, Red Kidney Beans, Peas, Salmon, Soy Beans, Tea, Walnuts, Whole Wheat and generally unrefined Whole Grains. Canned foods have a higher rate of nickel.
