Muscle & Strength explains that the best time to take whey protein for maximum results is right after working out. A person has an optimal time of 40 minutes after working out for his body to absorb the protein depleted during exercise.
Whey protein has proven benefits besides increasing muscle mass. In fact, according to WebMD, whey protein is a great addition to a healthy diet along with other sources of natural proteins from food. It can easily be added to foods or drinks and should be consumed throughout the day in small, appropriately sized amounts. However, after working out, the body is starved for nutrients and seeking proteins to replenish what was spent. The absorption of this complete protein also increases insulin sensitivity and has the potential of speeding the fat-burning process, boosting the immune system and combating muscular atrophy related to age.
