Posted by Protein is an essential macronutrient that plays a crucial role in the body’s growth, repair, and overall function. It is made up of amino acids, which are often referred to as the “building blocks” of life. These amino acids help in the synthesis of tissues, enzymes, hormones, and even DNA. Since the body doesn’t store protein, it must be consumed regularly through food sources to maintain muscle mass, immune function, and overall vitality. Mohit Tandon from Illinois suggested some of the Natural Sources of Protein.
While protein can be obtained from both animal and plant-based foods, many people are looking to improve their protein intake from natural sources to support health and fitness goals.
