Whey protein packs a concentrated amount of protein into each serving, which facilitates muscle growth, but it can also be expensive and may hinder weight loss efforts. Whey protein comes in powder form, making it easy to scoop and transport. However, each serving packs a hefty dose of calories, which may offset weight loss efforts.
Whey protein is readily available and is the most common and popular variety of protein supplements. It is often used as a protein-rich meal replacement supplement. It is easily digested and tolerated by the body, which makes it ideal for those with food allergies. However, in addition to adding calories, some supplements contain dyes, sweeteners and other additives.
