Yeah plenty of doctors on youtube.
I’m speaking from personal experince. Since I switched my diet from fast food many years ago, to the one, I have now - in which I include whey, I noticed many changes - ZERO acne, better blood, kidney and liver test results, clear skin, muscle gain, more energy and overall more strenght with sharp&focus thinking.
I also take vitamins, omega 3, black seed oil and magnesium with zink.
Never felt better in my entire life,mentally and physically.
That’s my case closed.
