Consuming whey protein along with exercise can help improve muscle protein synthesis and promote the growth of lean tissue mass. Whey gets absorbed really fast so you should eat protein every 2-3 hours as a result of protein synthesis only in last 2-3 hours so that your body can absorb so much protein. But did you know that after 1-3 hours of your workout the protein synthesis come into effect and it will keep elevated about 24-48 hours? If you’re taking your whey immediately after your workout you just to get 20-50 grams more protein.
Amino acid levels have to come below baseline level to re-sensitize muscle and thereby increase protein synthesis. That’s why it is better to have protein every 4-6 hours than every 2-3 hours. If you will increase amino acid levels within the blood, you will not increase protein synthesis or maintain protein assimilation by eating protein every 2-3 hours.
It seems to be the best shot you have at maximizing your protein synthesis level regardless of the rate of digestion. Strive to take whey with 20 to 30 grams of protein every 3 to 4 hours.
