DHEA (Dehydroepiandrosterone)

What is DHEA?

DHEA (Dehydroepiandrosterone )is a natural steroid hormone produced from cholesterol by the adrenal glands, the gonads, adipose tissue and the brain. DHEA is the precursor of, androstenedione, testosterone and estrogen. DHEA is a prohormone for the sex steroids.It is the most abundant hormone in the human body. DHEA is produced from cholesterol through two cytochrome P450 enzymes. Cholesterol is converted to pregnenolone by the enzyme P450 scc (side chain cleavage) and then another enzyme CYP17A1 converts pregnenolone to 17a-Hydroxypregnenolone and then to DHEA. In humans DHEA is the dominant steroid hormone and precursor of all sex steroids. Production of DHEA begins around 6 years of age, increasing in quantity until peaking in early adulthood, around the age of 25, and declines afterwards to approximately 10% of peak levels by age 80

What is effective dosage for DHEA?

Recommended DHEA doses range from 50 to 100mg per day. Most DHEA products contain either 50mg or 100mg of DHEA, and you shouldn't take more than 100mg per day.Dosages of DHEA for men and women differ: men seem to be able to tolerate higher doses. Men have been shown to tolerate doses up 50 to 100 milligrams per day, while in women, the maximum recommended dose is 25 milligrams per day. However, because it is a hormone its use should be monitor by doctor.

What is the supplement source of DHEA?

The source material for DHEA powder is derived from wild yams, which are grown commercially. Plant sterols (a class of plant hormones) are extracted from the wild yams. The most common sterol is diosgenin, which has a molecular structure very similar to DHEA. In the laboratory, the diosgenin extract is converted to DHEA by clipping away a few side chains by means of chemical reactions. However, it is recommended that only pharmaceutical-grade supplements be used

Is it legal to use it?

The FDA (in America) banned the sale of DHEA as a therapeutic drug in 1996 until its safety and value could be reviewed. DHEA products on the market as dietary supplements are regulated under a 1994 law, the dietary supplement health and education act (DSHEA).Although it is legal to buy but it is banned by international Olympic committee.

• Like any and all androgenic steroid, DHEA can cause hair loss, especially in men. DHEA tends to increases levels of DHT (Dihydrotestosterone), along with testosterone, and DHT is a main cause in hair loss.

Do not use DHEA if you have a preexisting medical condition, are under forty years old, are on hormone therapy, or are sensitive to hormone therapy. Women need to exercise extreme caution when using DHEA, as research studies report that DHEA has a weak androgenic effect and may induce growth of body and facial hair.
