Q: Several months ago, I started adding 25 grams of whey protein to an afternoon smoothie each day. I was worried about muscle loss after reading an article. I have seen the sagging muscles and skin in my arms and thighs. I am a 71-year-old woman who plays tennis twice a week and goes to the gym about once a week.
I have friends my age who have started adding collagen powders to their smoothies to improve their skin and prevent further facial wrinkles. After researching collagen supplements, I learned that they contain collagen peptides and protein. The dosage and ingredients vary by vendor. What is the correct collagen dosage and ingredients I should be looking for? Is the protein in collagen the same as the protein in whey?
