pregnenolone is the mother hormone , dhea is then made from this and branches out to about 150 other hormones which include cortisol, progesternone ,estrogen and testoterone , pregnenolone is made from cholesterol , cutler recommends supplimentation of either dhea or pregnenolone ,

also dhea levels drop after the age of 25 ,and by the time most people reach the age of 60 the dhea levels are almost undetectable in the blood

the secret is to only suppliment what you are missing ,many online adds say to use 50-150 mg daily , that is way too much , your body only makes 17-20 mg of dhea daily when you are 25 , so most people only need to suppliment that much daily ,anymore than that can cause health problems
