In addition, the USDA has been warning for decades about the consequences of mineral-depleted soils on American farms. Some groups of people may need a daily increase in minerals, especially the elderly, pregnant women, patients on certain medications, people on low-calorie diets, and vegetarians. There is reason to believe that prudent supplementation could have a positive effect on the immune system, reduce the risk of disease, and help to maintain bones, health and fitness in general. Although all minerals are inorganic, Neolife seeks to use forms that are organically derived. For example, calcium can be mined from the earth or obtained from an organically-derived source like eggshells.
Eggshells are better for several reasons.
One is purity. Mined calcium carbonate has been shown to contain small, but significant amounts of other minerals, both desirable and undesirable, including lead and aluminum. This is a concern. For example, vitamin D is added to Cal-mag. Minerals are composed primarily of positively charged ions.
