DHEA (dehydrpepiandrosterone), androstenedione, male hormones such as testosterone precursors, can increase testosterone levels.DHEA is the most abundant hormone in the body, thousands of times more than other hormones in the body, and is produced by the adrenal gland, also known as the “anti-aging hormone”.Studies have shown that DHEA can regulate and promote the secretion of 18 other sterol hormones in the body, and it can promote metabolism, maintain normal functions of the body, resist aging and enhance immunity. Therefore, it is also known as “youth hormone”.In clinical studies, DHEA can improve immune function, resist degeneration and prevent infectious diseases, promote the production of t cells, b cells and macrophages of the immune system, prevent the infection of bacteria and viruses, and inhibit obesity, cancer prevention, and reduce cholesterol and blood lipids.
