Whey protein powder is helpful for seniors, who may not be getting enough protein in their diet, to meet the minimum daily requirement. Powders can be added to water, making them convenient and easy to consume for those who struggle to get enough protein through food sources.
A quality whey protein powder contains all nine of the essential amino acids, which the body can't produce on its own and must be derived through diet. Whey protein is better at developing lean muscle mass compared with other protein supplements, such as casein, soy or egg-white protein supplements. As of 2015, whey protein supplements are not regulated by the Food and Drug Administration, and ingredients labels may not be accurate on some products.
