What is Pregnenolone?
Pregnenolone is a hormone that is manufactured from cholesterol and acts as a precursor for the production of many hormones in the human body including DHEA, estrogen, progesterone, testosterone and cortisol. As you age, your body produces less of this hormone and researchers believe that low levels of it can be a factor in the development of “old age” symptoms.
Pregnenolone Supplement Benefits
Pregnenolone supplementation may be beneficial for low libido, high cholesterol, type 2 diabetes, osteoporosis, obesity, loss of muscle mass, memory problems, blood clots, depression, and fatigue. For women, it may also relieve menopausal complaints like hot flashes, night sweats, fatigue, poor memory, low libido and dryness of the skin and hair.
It is a restricted substance in Canada because it affects the levels of many hormones in the body. Large-scale human trials have not been conducted to assess the safety of this hormone in supplemental use.
Supplement Alternatives
If you don't want to take this supplement itself, there are several natural supplement alternatives like essential fatty acids and protein.
Essential fatty acids are used to make steroid molecules, the precursors to hormones like pregnenolone, and protein is what the body uses to build muscle and repair tissue under the direction of hormones like this one. A proper balance of vitamins and minerals are needed to provide raw materials for the increased activity that the body will undertake when it is stimulated by pregnenolone.
Cautions & Considerations
Use caution when taking pregnenolone because the full spectrum of its activity and interactions is not yet known. It can potentiate the activity of any medication that has hormonal activity like hormone replacement therapy, prostate cancer medication and corticosteroids. Do not use pregnenolone if you are pregnant, nursing or have a history of breast or prostate cancer. Side effects of this hormonal supplement may include headache, insomnia, irritability, mood swings, irregular heartbeat, acne, growth of facial hair and loss of scalp hair.
I didn't know that pregnenolone was age-depleted and has so many functions! I wonder: do pegnenalone levels vary throughout the menstural cycle or pregnancy? If levels vary cyclically I wonder if there would be any additional benefits associated with cyclic supplementation. Anyway, it's incredible that supplementing pregnenolone can have a myraid of benefits including support for: low libido, type 2 diabetes, high cholesterol, obesity, loss of muscle mass, osteoporosis, memory difficulty, low mood, menopausal complaints such as hot flashes (in women), fatigue, depression, and blood clots. That is a pretty extensive and amazing list of benefits!!
