Estrogen Balance Criticle to Aging Men

Estrogen Balance is Critical to Aging Men A study published in the Journal of the American Medical Association (JAMA) measured blood estradiol in 501 men with chronic heart failure. Compared to men in the balanced estrogen quintile, men in the highest quintile (serum estradiol levels of 37.40 pg/mL or greater) were significantly (133%) more likely to die. Those in the lowest estradiol quintile (serum estradiol levels under 12.90 pg/mL) had a 317% increased death rate compared to the balanced group. The men in the balanced quintile—with the fewest deaths—had serum estradiol levels between 21.80 and 30.11 pg/mL (Ewa et al 2009). This is the ideal range that Life Extension has long recommended male members strive for. An epidemic problem we at Life Extension observe in aging male members is insufficient free testosterone, i.e., less than 20 - 25 pg/mL of serum. When accompanied by excess estradiol (over 30 pg/mL of serum), this can signal excess aromatase enzyme activity. If you would like to learn more please contact Ann Arbor Life Extension.
