Supplements are just that – they “supplement” your food. They were never there to replace food. If you are not eating whole foods and just using supplements – you are losing out what whole foods can provide.
Whey Protein generally is easily digestible. Taking it alone would be absorbed by the body relatively quickly hence you should take whey protein within 30 to 60 minutes after a strength-training based workout. At all other time, you would want to slow down the digestion of the protein by eating it with other foods. For example, if you want extra protein for breakfast, but don’t want eggs, you can add the whey protein powder to some oats, in various pancake recipes.
Whey protein is a liquid byproduct of cheese production that is sold as a dietary supplement in protein powders and shakes. Whey protein used to be discarded by cheese manufacturers as a waste product.
IMPORTANT TO NOTE:
I remember being a kid many years back and mom forcing me to have a tablespoon of fish oil. She said it was good for me and it would make me smart. All i remembered was it tasting yucky. Little did i know Mom got it right.
