The author quotes Ray Peat saying that with insufficient cholesterol the high postpartum progesterone is unlikely to be maintained, and that pro-inflammatory effects of serotonin and estrogen then predominate, causing depression, joint pain, anxiety and brain edema. The author adds that postpartum depression drugs (brexanolone, zuranolone) relate to allopregnanolone, a progesterone metabolite. They also lay out the cholesterol-to-allopregnanolone pathway and note its dependence on T3 and vitamin A. They cite a postpartum cholesterol and mood study (PMID 8845727).

Author argues Ray Peat is wrong to compare resveratrol to DES. The author claims resveratrol binds estrogen receptors far more weakly than DES or estradiol, suppresses inflammatory genes rather than activating proliferative ones, and showed no carcinogenic signal in human megadose studies. The post quotes KruseYouri's "Ray Peat on resveratrol" post.

nootropicguy adds that resveratrol is not a proliferative agonist like estradiol or DES. He claims it is pathway-selective for anti-inflammatory signaling rather than cell growth, so its very weak estrogen-receptor binding is not relevant. This continues his own post disputing Ray Peat on resveratrol.
