Whey protein vs. Soy protein


Whey is a milk-based product and provides a good source of protein, vitamins, minerals and lactose. It is often used in supplementation to help build or repair muscle tissues. It can help with mobility of limbs and prevent atrophy of muscular cells. Add egg whites in addition to supplements of whey to achieve the protein levels. Whey protein has low fat content so it can be used in weight loss.  It has been shown to help with:
  • Maintaining proper weight
  • Antibacterial
  • Improving the function of the immune system
  • Improving blood pressure
  • Improving function of digestive system
 vs.


Soy protein is from soybeans and is a better option for those who are lactose intolerant. Soy contains less cholesterol compared to whey. It has been seen to help reduce developing osteoporosis. It can speed up metabolism of the thyroid, which could possibly assist in weight loss.  This is also a common type of protein used in a vegetarian diet. Soy has about twice as much glutamine per 100 grams of protein compared to whey.  Glutamine is needed for many functions in the body so in this area, soy would be a better option.

I would pick soy since it is plant based.  However, whey has lower fat and can help with maintaining weight or losing weight.  It is similar to yogurt in terms of the bacteria that helps with the digestive tract. Whey protein would also help after a long run (half-marathon) for building and repairing muscle cells that were damaged.  I would add whey protein along with the soy for both benefits from both animal and plant sources of protein. Soy protein since it is plant based avoids the health risks that could arise from consuming plant-based sources of protein.

I found this website while looking over the two different products.  For more information about the two I would recommended reading further from here:
