The first ingredient in Sustain Alpha, that has recently become well known for its heart-health and life-extending benefits, is resveratrol. Aside from the noteworthy health benefits, resveratrol is an "estrogen blocker" because of its unique chemical structure which binds to the estrogen receptor, thus blocking estrogenic activity. (1,2) As discussed before, blocking estrogen can help increase LH & FSH levels.
The estrogen modulating effects of resveratrol have been proven to dramatically increase testosterone levels, fertility, and erection strength in several animal studies, without any side-effects. (3-4) Other research with resveratrol has uncovered its supportive role in healthy blood vessel function - a great benefit for any male interested in improving his heart-health and erection fullness.

The second ingredient in Sustain Alpha is 7,8 Benzoflavone. This neuro-active flavone has the ability to pass the blood brain barrier and block the suppression GnRH release through modulation of the GABAergic receptor complex. (6,7,21-30)
7,8 Benzoflavone also has the unique ability to reduce production of potentially dangerous and cancer causing estrogenic metabolites, such as 4-hydroxylated quinines. (11) Other research has shown 7,8 benzoflavone to have positive effects on libido due to its aphrodisiac and anxiolytic (anxiety-relieving) effects. (10-13)
