Diary of Unknown Symptoms

Mystery of the Internal Vibration

Entry for July 22, 2007


So what I find interesting is that in everything that I’ve read, they all seem to say that chromium is a difficult mineral to absorb. So why did it work after one dosage for me? I used a formula called Chromium Picolinate.

Chromium

Chromium is a difficult mineral to absorb. Figures range from 0.5-3 percent absorption for the inorganic chromium salts often found in food. The organic complexes of chromium, such as GTF, are absorbed better, at about 10-20 percent. The kidneys clear any excess from the blood, while much of chromium intake is eliminated through the feces. This mineral is stored in many parts of the body, including the skin, fat, brain, muscles, spleen, kidneys, and testes.

Following yeast in chromium concentration are beef, liver, whole wheat, rye, fresh chilies, oysters, potatoes, wheat germ, green peppers, eggs, chicken, apples, butter, bananas, and spinach. Yeast (44 ppm), black pepper (10 ppm), and molasses (2 ppm) are good sources of chromium, but since they are usually consumed in small quantities, it is best to have other chromium foods in the diet. In general, the whole grains, meats, shellfish, chicken, wheat germ and bran, and many vegetables, especially potato skins, are adequate sources. Beets and mushrooms may contain chromium.

Requirements: There is no specific RDA for chromium. Average daily intake may be about 80-100 mcg. We probably need a minimum of 1-2 mcg. going into the blood to maintain tissue levels; since only around 2 percent of our intake is absorbed, we need at least 100-200 mcg. in the daily diet. A safe dosage range for chromium supplementation is between 200-300 mcg. Children need somewhat less.

Many vitamin or mineral supplements contain about 100-150 mcg. of chromium. Some people take up to 1 mg. (1,000 mcg.) per day for short periods without problems; this is not suggested as a long-term regimen but rather to help replenish chromium stores when deficiency is present. All of the precursors to the active form of GTF are used in some formulas, but usually with chromium in lower doses, such as 50 mcg., since it is thought to be better absorbed with niacin and the amino acids glycine, cysteine and glutamic acid.

The Best Form of Chromium

Chromium picolinate is a unique molecule that combines chromium with picolinic acid, a compound found in breast milk, which helps the body better absorb and process minerals. In 11 clinical trials, chromium picolinate has distinguished itself as more bioactive than other forms in insulin resistant people.

In a sampling of 31 studies using chromium picolinate, chromium polynicotinate and chromium chloride, chromium picolinate had the greatest number of studies supporting its efficacy. More importantly, a greater percentage of the total number of chromium clinical studies show significant positive benefit in blood glucose control in people with diabetes when chromium picolinate is the supplement.

For example, 91 percent of studies with chromium picolinate showed significant benefit while only 38 percent of chromium chloride studies showed any benefit. and only 29 percent of studies using other forms of chromium showed any positive results; conversely, a majority (71 percent) of studies using other forms of chromium showed “no significant benefit.”
