@Peatly said in Vitamin A quotes from Ray's favorite physiology book:
@Mauritio There are huge variations in results for vitamin A studies. I think Dr Peat’s recommendation, which is to be cautious if hypothyroid, seems reasonable. I would like to see that Iranian study replicated elsewhere – especially in regions where Billy Goat is blocking the sun.
Yes, I agree.
What does it have to do with the sun/ Vitamin D?
I was under the impression that being exposed to sunlight, for extended periods, increases your vitamin A requirements. I was thinking that if the sun is being blocked this might lower need?
