The use of garlic in the form of a food supplement or supplementation is usually associated with the practices of our grandparents, where folk medicine ordered to eat it when it caught us in a state of reduced immunity.
As research shows, certain sulfur compounds contained in the plant perform not only pro-health functions, but also show some anabolic features.
Researchers from Japan conducted an experiment on three groups of rats. They gave rats feed, which varied in protein percentage, and the amounts were divided into 10%, 20%, and 40%. Subsequently, all three groups were divided into two smaller ones, where one received feed enriched with garlic powder and the other received feed without garlic. 1 kg of feed contained 8 g of garlic. 1 g of garlic contained 5 mg of diallyl disulfide.
The rats were fed with feed for 28 days, after which the nitrogen balance was measured.
The addition of garlic did not affect the nitrogen balance in the group of 10 and 20% of protein. However, in the group that consumed 40% of the protein in the diet, the subgroup with the addition of garlic showed an increase in the nitrogen balance.
The level of testosterone increased in proportion to the amount of protein consumed in the groups of rats receiving the addition of garlic, and the level of corticosteroids was lower in the groups eating the garlic feed.
Researchers in Japan linked their observations on testosterone stimulation with the content of diallyl disulfide. It is a substance that affects the level of LH, and this, in turn, stimulates testosterone in the testes. The greater amount of stimulated hormone correlates with more protein in the diet, which gives us a picture of the increased nitrogen balance.
