How To Choose a Protein Supplement

Protein supplements are popular among athletes and bodybuilders, as well as people who are on a weight loss diet or who are worried about getting enough protein. Most protein supplements are in powder form and available in two main varieties, soy and whey. Regardless of which protein supplement you choose, there are important health warnings to consider.

One of the main ingredients in soy protein supplements is soy protein isolate. During the process of making soy protein isolate, a toxin called lysinoalamine is formed and the processed soybeans are exposed to high levels of aluminum, which make their way into the final product.

Spray drying the product at high temperatures makes the other proteins in soy ineffective. Powerful carcinogens called nitrites are also formed during spray drying. Overall, soy protein isolate is a substance to avoid.

Whey protein is composed of byproducts from cheese production. In addition to the possibility of causing allergic reactions in people who are lactose intolerance, whey protein has also been associated with kidney problems and liver damage. Excessive consumption of whey protein can result in a calcium and collagen deficiency, which could lead to poor bone mass and osteoporosis. High intake of whey protein is also associated with cramps, gout, headache, loss of appetite, nausea, and tiredness.

Protein supplement powders typically include added ingredients and chemicals that do not promote good health. In addition to soy protein isolate, some of the other ingredients you can expect to see on protein supplement labels include milk protein isolate, whey protein isolate, taurine, oils, fructose, sucralose, aspartame, and artificial flavors and colors, L-glutamine, and others. Non-soy, non-whey based protein supplement powders are available, but the ingredients on these products need to be checked as well. Before buying a protein supplements, it is recommended you check with your healthcare provider to determine whether you need more protein, and to find healthier alternatives.
