Testosterone is classified as a sex hormone, and while it plays a crucial role in the development of the male reproductive system, this hormone is also found in women. Although the primary responsibilities of testosterone are to support sperm production, promote muscle growth and enhance ovarian function in women, a lack of this hormone may cause a decrease in energy levels. Testosterone supplements may help naturally improve energy as well as sharpening your focus and libido; however, never begin taking testosterone supplements without the direct consent from your physician.
What Are Testosterone Supplements?
Consuming testosterone supplements, which is often referred to as testosterone therapy, is primarily used for men whose pituitary glands do not produce ample amounts of testosterone because of injury or tumors. Testosterone supplements are generally considered unnecessary or even unsafe for most men who are not suffering from a serious testosterone deficiency. Testosterone supplements are available in capsule, patch, gel or injection form, and while proponents of these supplements proclaim it increases energy levels, sexual desire and mental focus, very little scientific evidence is available to determine its true value and safety.
Evidence on Energy Levels
The June 2006 issue of the “Journal of Clinical Endocrinology & Metabolism” cites uncontrolled studies found men who underwent testosterone therapy experienced an increase in energy. A study published in the February 2000 issue of “General Psychiatry” found 59 percent of HIV-positive men who received testosterone therapy experienced an increase in energy levels. This study suggests HIV-positive men may benefit from short-term testosterone therapy; however, further studies are required to determine its value on HIV-negative men.
Recommended Intake
There is no official dosage of testosterone. Because of the risk of developing serious side effects, do not begin a testosterone supplement program without first discussing the use of testosterone with your physician. While testosterone therapy is beneficial for those with a medical condition that lowers natural testosterone levels, the use of this hormone to treat normal aging or a lack of energy is not condoned by the medical community.
Side Effects
Side effects associated with testosterone therapy include acne, enlarged breasts, inhibited sperm production, testicular shrinkage, heart disease and sleep apnea.
