Health Risks of Protein Supplements

Athletes, students, and dieters may take protein supplements to increase energy levels, gain strength, build muscle or promote weight loss. But there’s a lot of controversy surrounding high-protein intake because of its potentially negative effect on health.

Creatine and Dehydration

• Creatine is one of the most popular protein supplements used by athletes. As a diuretic, creatine increases the flow of urine, and without proper hydration, this supplement can strain the kidneys and liver.

Increased Risk of Calcium Excretion and Osteoporosis

• Diets high in protein are shown to increase calcium excretion by up to 55 percent. This can potentially lead to bone loss and the possible risk of osteoporosis.

Digestibility

• Protein supplements should never be used as a substitute for the protein obtained in food. Furthermore, supplements are not as easily digestible as protein-rich food, and studies show that most athletes taking supplements already get the protein they need from their diet.

Supplement Impurity

• A small percentage of supplements may contain the risk of containing prohibited drugs. If you are thinking of buying protein supplements, be sure to purchase them from a trusted manufacturer. Also, check to be sure that sodium, magnesium, niacin, folate, iron and vitamin A levels contained in the supplement do not exceed acceptable levels. Talk to a doctor if you are uncertain.

Following Directions

• Many people don’t read the label or follow through on instructions for taking their protein supplement. They take more than the recommended dosage, doubling or tripling it to get the rejuvenation and strength they feel the supplements give them. This can lead to symptoms such as nausea, fatigue, liver problems and other more serious risks.
