[Health Week] Do Protein Supplements Cause Acne and Hair Loss?
People who want to build muscle often combine exercise with protein supplements. Even new fitness enthusiasts naturally buy and consume protein supplements.

However, few people realize that protein supplements can cause acne. Dr. Lee Jin-hyeok, director of Chamjin Oriental Medical Clinic, explains, "Protein intake increases a growth factor called 1GH-1. 1GF-1 is an insulin-like growth factor that promotes cell proliferation and growth. When it acts on sebaceous glands, it promotes their growth." He adds, "This also promotes the growth of keratinocytes, creating an environment prone to acne."

Protein supplements are typically made from protein isolated from milk. Milk contains 80% casein protein and 20% whey protein. Whey protein is known to aid in muscle recovery, while casein protein is known to help maintain muscle mass. Therefore, those who prioritize muscle maintenance over muscle growth often choose products with a high casein protein content.

Some choose casein protein because whey protein is known to cause skin problems. Unfortunately, casein protein also causes acne through a similar mechanism.

The most common side effect of whey protein is gastrointestinal upset, such as gas and diarrhea, caused by lactose intolerance. Casein protein also clumps when exposed to stomach acid, which can cause indigestion.

Furthermore, the process of breaking down protein places a strain on the liver and kidneys. For this reason, those with kidney disease should be especially cautious when taking protein supplements. Long-term excessive protein supplement consumption can also lead to high blood pressure. Exceeding the recommended daily intake of two to three times the recommended daily amount increases calcium excretion in the urine, negatively impacting bone metabolism.

Protein supplements can also cause hair loss. The director stated, "Supplements contain creatine, and research has shown that taking it increases DHT levels, a major cause of hair loss."

So, what about plant-based proteins? If consuming animal-based proteins like whey or casein protein is difficult, some people choose plant-based proteins like soy, peas, and brown rice. Research has shown that there's little difference in muscle synthesis between plant-based and animal-based proteins.

However, plant-based proteins can sometimes lack certain amino acids, leaving you with unmet needs. In such cases, choosing a product that blends various plant-based proteins can be an alternative.

However, the best approach is to consume protein from natural sources, rather than supplements, as this reduces the risk of side effects. The director said, "Foods like beef, chicken breast, eggs, tofu, white fish, and oats contain a lot of high-quality protein."
