I'd like to make a searchable database of Peat's work to help answer questions like this.
I find references in Peat's work to Vitamin E helping with iron excess and PUFA poisoning that comes especially with aging, and to Vitamin K helping balance an environment that may be too stressful.
Here's an example of Peat describing this balance:
"Substances such as PTH, nitric oxide, serotonin, cortisol, aldosterone, estrogen, thyroid stimulating hormone, and prolactin have regulatory and adaptive functions that are essential, but that ideally should act only intermittently, producing changes that are needed momentarily. When the environment is too stressful, or when nutrition isn‚Äôt adequate, the organism may be unable to mobilize the opposing and complementary substances to stop their actions."
If you want to go outside Peat's work, this article provides a research summary:
But I find many studies are unreliable, likely designed by people who lack an understanding of the role of gradient affinities in cell physiology.
