Chromium (Cr) belongs to the group of microelements, which play an important role in the human body. In nature, there are two forms of this element: on 6th degree of oxidation (created as a result of human activity) and the 3rd degree of oxidation (chrome from natural origin).
In dietary supplements chrome on the 3rd degree of oxidation is used as it is non-toxic to the body. This element used in preparations can occur in the form of several chemical compounds, such as chromium polynicotinate, chromium gluconate, chromium citrate or chromium picolinate. As an effective and non-toxic form of this microelement, the chrome built-in protein of bakery yeast (Saccharomyces cerevisiae) is also applied.
In the human body chromium content does not exceed 6 mg. This element occurs primarily in the kidneys, spleen and testes, and a small amount can be found in the heart, lungs, pancreas and brain. Chromium excretion from the body occurs mainly during the excretion of urine.
Chromium, just like any other macro- and microelements is absorbed in the small intestine and colon. This process is inefficient and largely depends on the degree of oxidation of the microelement and its forms. Organic forms than inorganic ones of chromium characterize definitely better absorbing.
There are compounds that have more effective process of absorption of chromium. These include, among others: glycine ascorbic or aspartic acids. In turn, simple sugars, zinc, manganese, calcium and iron can contribute to reduce the absorption of this microelement.
A deficiency of chromium in the body can contribute to:
- the development of type II diabetes,
- reduce the metabolism of amino acids,
- reduce the absorption of carbohydrates,
- an increase in the level of cholesterol and triglycerides,
- fast onset,
- irritability, depression.
Dietary supplements containing chromium in its composition can be used for:
- increased levels of cholesterol and triglycerides,
- excess body weight (obesity),
- postmenopausal osteoporosis (by restricting the process of excretion of calcium from the body),
- irritability states, headache pain.
When selecting preparations that contain chromium compounds, it should be considered to the three aspects: the content of microelements, chromium form (organic chrome features a better acquisition than inorganic chromium), the presence of the preparation additional ingredients such as vitamin B3 (facilitates the absorption of chromium), other minerals and green tea or extract of red tea Pu-Erh- to assist the process of weight loss.
Recommended daily intake of chromium is from 50 to 200 µg. It should be noted that, however the body’s demand for the microelements increases with physical exertion and in the high-carbohydrate diet. Due to the low percentage of chromium absorbed by the human body, the use of dietary supplements enables our diet to enrich it with this microelement.
