Testosterone: Free-Testosterone and Plasma Protein-Bound Testosterone
Testosterone exists in the blood in either an active (free) or unbound state (+-2%) or inactive state bound to one of two proteins: sex-hormone-binding-globulin (SHBG) (+-45%) or albumin (+-53%). Only when testosterone is in its free state can it directly interact with cellular receptors and exert its activity. SHBG preferentially binds to testosterone over estrogen. Higher levels of SHBG in women help to maintain higher estrogen to testosterone ratios. Increased estrogen leads to an increase in SHBG. Thus, lowering the level of SHBG allows for an increased level of free testosterone. Obviously, if testosterone finds it more difficult to locate available plasma proteins in the presence of the additional compound, more will be left in an unbound state.
The amount of free testosterone can be altered (increased) by the use of aromatase inhibitors (the less testosterone that is synthesized [aromatized] into estrogen, the more total testosterone) or inhibitors of the plasma proteins that bind into testosterone. Manipulating the tendency of a testosterone to exist in an unbound state is an effective way to alter the overall activity and potency of one?s overall testosterone levels. Higher levels of testosterone produce an enhanced anti-glucocorticoid effect, which yields an anti-catabolic, or more precisely, anti-proteolytic, effect on muscle cells. This indirect anabolic effect is the result of testosterone?s high affinity for binding with glucocorticoid receptors, thus blocking the normal messenger pathway that triggers protein release from muscle tissue. More free testosterone also likely results in higher concentrations of IGF-1 and IGF-1 receptor sites in skeletal muscle tissue. Correspondingly, lower testosterone also likely yields less IGF-1 production and a corresponding decrease in IGF-1 receptor sites. Lower free testosterone also likely means a weaker immune system.
The Synthesis (Aromatization) of Testosterone to Estrogen in Males and the Significance of Maintaining Correct Testosterone to Estrogen Ratios.
Although testosterone is considered to be a male hormone and estrogen a female hormone, both hormones exist in both males and females and serve important functions for both. Estrogen is a term that really represents a collection of female hormones, with estrone predominating. Since estrone is the estrogen that is normally in the highest concentration, it is an excellent marker for basic estrogen levels for that reason. At least three estrogens have multiple and overlapping functions. Men obtain their estrogen through the action of the aromatase, which synthesizes (aromatizes) testosterone into estrogen. However, when concentrations of estrogen become too high and/or the normal ratio of testosterone to estrogen decreases, the potential for the development of undesirable conditions arises. This includes the development of the female breast tissue (gynecomastia), increased body fat and water retention. Also, research suggests that DHT and prostate tissue growth have a direct connection to above normal estrogen elevations and reduced testosterone levels.
The ESTROGENEX - Mechanism of Action
The ESTROGENEX - proprietary formula was developed by combining naturally occurring aromatase inhibitors and inhibitors of the action of SHBG. The primary active ingredients in ESTROGENEX are Coumesterol and Chrysin. ESTROGENEX does not exert its action through any direct hormonal activity
Before ESTROGENEX, little success had been achieved using chrysin as an effective aromatase inhibitor because chrysin is poorly absorbed in the bloodstream. However, in addition to their own specific aromatase inhibiting and estrogen-blocking actions, the proprietary blend of other ingredients work in synergy with chrysin to maintain a stable estrogen environment. We also incorporated our proprietary delivery system called EXTEND-RX? to avoid competing with other hormones such as testosterone in the Aromatase Cytochrome P450.
It is believed that ESTROGENEX exerts its effects through several mechanisms of action, which can be classified into two groups:
- as an inhibitor of the aromatase enzyme responsible for the conversion of testosterone to estrogen and an inhibitor of the action of SHBG, and
- as a blocker of selective anabolic estrogen receptors and/or inhibitor of selective estrogen signaling.
Substances that are aromatase inhibitors block the action of the enzyme aromatase that converts testosterone to estrogen. Substances that act as an anti-estrogen are those that block the estrogen receptor. Thus, even though there is estrogen circulating in the blood, the estrogen cannot exert its effects because it is blocked from attaching to its estrogen receptor. The dietary supplement ESTROGENEX ? is a multi-pathway agent that exerts its influence by blocking various stages in the aromatase process and by inhibiting SHBG's action; an activity not clearly addressed by any of the aromatase inhibiting or anti-estrogen products. Further, it appears that the use of ESTROGENEX may result in long-term blocking of selective anabolic estrogen receptors and/or inhibition of selective estrogen signaling (these anabolic estrogens are those demonstrating the undesirable effects associated with breast cancer and gynecomastia). This activity has not been addressed by any known dietary supplements or pharmacological agents.
ESTROGENEX as an Elevator of Total Testosterone and Liberator of Free Testosterone
As a powerful aromatase inhibitor, ESTROGENEX also possesses notable testosterone stimulating properties. The aromatase inhibiting action reduces the signal that estrogen sends to the brain to suppress endogenous testosterone production (estrogen is a main feedback signal to control the release of testosterone, thus increasing the testicular output of testosterone). ESTROGENEX thus assists in resetting the body's level of its own natural testosterone production by regulating the activity of the hypothalamic-pituitary-testicular axis (HPTA), which constantly adjusts the body's production of testosterone to maintain target blood levels. Continued use of ESTROGENEX results in not only a significant reduction in the production of estrogen, but also a corresponding substantial increase in endogenous testosterone.
Only ESTROGENEX addresses all possible channels to estrogen maintenance and free testosterone elevation, which means optimal hormonal levels for muscle building, fat loss, and anti-aging support.
