Hormonal Balance After the Menopause Transition

Following menopause, the natural decline in endogenous ovarian estrogen production frequently triggers increased arterial stiffness, hot flashes, and adverse shifts in lipid profiles (dropping protective HDL and raising LDL).

In a randomized, double-blind, placebo-controlled pilot study (Gossell-Williams et al.), post-menopausal women supplementing with $2\text{ g}$ daily of cold-pressed pumpkin seed oil for 12 weeks experienced:


  1. Significant Elevation of Protective HDL: Serum high-density lipoprotein cholesterol rose substantially, accompanied by a notable drop in systolic blood pressure.

  2. Vasomotor Symptom Relief: Women reported marked reductions in hot flash severity, headaches, and joint discomfort.
