Gordo Posted March 7, 2019 Report Share Posted March 7, 2019 I have never had my IGF-1 tested, but would like to do so. Anyway, I stumbled upon this commentary today from Dr. Joel Fuhrman where he says for LONGEVITY the ideal IGF-1 is between 100-150 ng/ml, not the >200 most American's have, and below 80 is bad: He also talks about changing protein requirements as we age, <80 you probably only need 0.8g/kg (40-50g protein/day for most people), over 80 you may need up to 50% more protein (about 70g for a 150lb person). He eats animal products a few times a year: Quote Link to comment Share on other sites More sharing options...
