Introduction
Insufficient protein intake in the daily diet, or individuals who engage in significant physical activity and require additional protein supplementation, can generally consume protein powder in moderation over the long term without notable side effects, provided they maintain a balanced diet. This practice can aid in maintaining normal metabolic function and muscle repair. However, long-term excessive consumption of protein powder may increase the burden on the digestive system and could potentially lead to symptoms such as bloating and constipation.
Generally, long-term consumption of protein powder may have side effects. It is acceptable to consume it in moderation along with a balanced diet. However, excessive consumption or having pre-existing liver or kidney conditions makes it unsuitable. Detailed analysis is as follows:
For individuals whose daily diet lacks sufficient protein or those with high physical activity requiring additional protein intake, long-term and moderate consumption of protein powder, combined with a balanced diet, typically does not cause significant side effects. It can help maintain normal metabolic function and muscle repair.
However, long-term excessive intake of protein powder can burden the digestive system, potentially causing symptoms such as bloating and constipation. For individuals with existing liver or kidney issues, excessive protein metabolism increases the workload on these organs and may negatively affect their function. In such cases, long-term use of protein powder is not recommended.
When consuming protein powder long-term, it is important to control the dosage, regularly monitor health status, and discontinue use promptly if any discomfort occurs, consulting a healthcare professional as needed.
