Health and Fitness Hints

There are many trace minerals that occur in µg/gram amounts in the human body. It is possible that these minerals such as Silicon, Vanadium, Boron, Nickel, Lithium and many more, may or may not have health benefits or at least proven benefits in humans.

In fact some of these minerals may be toxic as it is the case of lead. However, in time some of them may prove their usefulness and may be elevated to essential nutrient status such as vitamins and other minerals. Knowledge from studies with animals for some of these minerals suggests possible benefits for humans. The following minerals are those most likely to be of benefit.

Nickel (N) No clear biochemical function has been defined for this trace mineral. It may function as a cofactor in several enzymes and in the metabolism of the vitamin B12, folic acid and vitamin C.High concentrations of nickel are found in RNA and DNA where it interacts with these nucleic acids. Based on animal experiments upper level for nickel is 1 mg/day. High nickel intake, usually from non-dietary sources can interfere with vitamin E that could lead to angina or other cardiac. Dietary sources for nickel include nuts, grains, chocolate and dry beans.

Silicon (Si) Silicon is one of the minerals that is widely distributed in the soil, water and plants. In the human body higher concentrations are present in connective tissues such as collagen, cartilage, tendons, eyes dental enamel, skin, hair, thymus and bone. Specifically, silicon in bones is mostly found in areas of active growth. It changes the composition of cartilage of bone and promotes calcification. Silica promotes the union of bone after a fracture. The average intake of silicon is 30 to 50 mg/day. There is not set upper level for this mineral. Most of the dietary silicon is not of an easily absorbable form. Best dietary sources include Whole grains, onions, lettuce, root vegetables, the herbs horsetail, nettle and comfrey.

Boron (B) Boron is one of the dietary trace minerals found primarily in plant foods. It has long been known as a growth factor for plants. In the human body it may be involved in the metabolism of hormones such as estrogens and of vitamin D. This mineral also appears to have a close interrelation with magnesium and calcium. It has been suggested that boron acts as a cell membrane regulator; stability of membranes and the movement of anions and cations through the membranes. Boron benefits include healthy bones and proper brain functioning. Nutritional forms of boron are easily and completely absorbed. Based on animal tests upper level for boron is 20 mg/day. Good sources of dietary boron are beets and other vegetables, legumes, peanuts, fruit, raisins and wine.

Vanadium (V) This trace mineral has shown pharmacological activity similar to that of insulin. In clinical studies suffering type 2 diabetes individuals showed insulin sensitivity improvement. Animal studies suggest that high dosages of vanadium may be harmful. Upper level for vanadium is 1.8 mg/day. Good sources of dietary vanadium include mushrooms, shellfish, corn, and the herbs parsley and dill. A significant amount of research is still required to determine if vanadium and other minor trace minerals have significant health benefits.
