Nickel

Nickel is a naturally occurring mineral found in healthy foods such as nuts, grains, peas, and beans. We have known since the 90s that the human body will also absorb and metabolize nickel if it is taken as an oral supplement [1]. Therefore, nickel is also used as a dietary supplement in liquid mineral tinctures. Nickel is usually ingested in this form to improve iron absorption and treat anemia, and to strengthen bones and help prevent osteoporosis.

Nickel Research

Nickel is understood to be a vital component in a number of important human biological processes, but its exact role in those processes still remains a mystery . Fortunately, scientific research of this substance has been ongoing, particularly as nickel continues to gain traction as a dietary supplement.

Weight Loss

In particular, nickel is finding new life in contemporary weight loss applications. In 2004, researchers tested on a very basic, biochemical level, the value of nickel as a health-fortifying agent and weight loss supplement. They introduced varying levels of nickel to rabbits and broilers (chickens raised specifically for meat) and compared those animals to a control group that had no nickel. Interestingly, at 50 mg dosages of nickel, the chickens and rabbits were stronger and gained weight at a slightly increased rate. However, as researches proceeded to ramp the dosage up to a comparatively massive 500 mg, the nickel harmed the livers of the animals while impairing digestion and weight gain.This supports the idea that there is a “sweet spot” with nickel intake. Though it can improve absorption and even lead to weight loss, too much can be harmful.

In 2011, two Polish researches theorized that there was a relationship between 16 different weight loss products on the market, and the potential nickel content in those products. After heating and introducing the weight loss products to acid to simulate human digestion, they indeed identified high levels of nickel in the products .

Nickel in Cigarette Smoke

A 2004 study found that, in addition to the growing laundry list of far more dangerous, highly carcinogenic substances in cigarettes, smokers also expose themselves to large doses of extra nickel by smoking. Significantly higher, carcinogenic levels of nickel were found in the urine of smokers over non-smokers [5]. This again speaks to the potential challenge with nickel quantities: Though the positive value of nickel in our diets is undisputed, like with most things, too much nickel may be harmful to us.

Nickel is one of the oldest and most prolific minerals on our planet. It is surprising, then, that we are just scratching the surface when it comes to its potential benefits to human health. From the traditional uses of treating and preventing anemia and osteoporosis, to experimental new weight loss applications, the uses for nickel seem ever-growing. Provided caution is used in meting out dosages, nickel can indeed make us happier, healthier people.
