Chromium is in the form of organic compounds and trivalent and hexavalent inorganic compounds.Only hexavalent compounds that are not found in foods are toxic.Chromium is a component of many enzymes, it participates in the metabolism of proteins and nucleic acids.Organic chrome together with niacin, glycine, cysteine and glutamic acid form the so-calleda glucose tolerance complex (GTF) that assists insulin action.
Chromium deficiency in the body causes so-calledfunctional hypoglycaemia and the phenomenon of the sugar roller coaster – roller coaster.A few hours after a meal there is hypoglycaemia manifested by a feeling of hunger, fast heart action, shaking hands, increased sweating and tiredness.
These symptoms disappear after the consumption of sweets, which increases the secretion of insulin.After a transient increase in glucose concentration, blood levels fall further in the blood and a vicious circle is created.
The above sequence of phenomena causes the hunger of sweetness, leading to obesity and other diseases connected with it.

In patients treated with brewer’s yeast, glucose tolerance was significantly improved with a simultaneous decrease in plasma insulin levels.There was also a significant decrease in plasma cholesterol and lipids.
Other studies suggest specific effects of brewing yeast on specific lipoprotein cholesterol fractions.18 g per day of brewer’s yeast administered for 8 weeks to healthy people significantly reduced LDL cholesterol levels and caused an increase in HDL content in the blood.
Similar results were observed when 7 g / day of brewer’s yeast was administered for 6 weeks.The level of LDL cholesterol (bad cholesterol) decreased by almost 18%, while HDL cholesterol (good cholesterol) increased by 17.6%, resulting in a reduction of the LDL / HDL ratio by 28%.
Indications for chromium supplementation are
RDA (recommended dietary allowance) for chromium is 50 and ESADDI 200 μg.ESADDI (estimated safe and adequate daily dietary intake – the highest dose for which side effects were not observed).
The most rich natural sources of chromium are yeasts, especially brewer’s yeast.
Recently, many preparations containing chromium have been published, recommended as a means to prevent and treat overweight and obesity.
