Protein is amid the three vital components of the diet, along with fats and carbohydrates. It contains various amino acids, plays a crucial role in the endocrine and immune system, offers raw material for muscle construction as well as repair, and also helps in the transmission of nerve impulses all through the nervous system. Though people can get bulks of protein from whole food sources, but protein supplements make it simpler in getting the same on-the-go. Today both animal and plant-based protein supplements are available in the market in different forms such as bar, powder, liquid, and others. Weight management, muscle growth, recovery after exercise, and added nutrition are some of the key benefits of taking protein supplements.
