High-protein diets and fitness supplements are increasingly popular for enhancing strength and recovery. However, excessive protein intake can place significant strain on the liver, which is essential for processing protein and maintaining overall health. The liver's functions include breaking down amino acids, converting toxic ammonia into urea, and synthesizing important proteins. For most people, a daily intake of 1-1.5 grams of protein per kilogram of body weight is sufficient, with higher amounts needed for athletes. While protein supplements can help meet dietary needs, they should be used cautiously due to potential health risks, including liver dysfunction. In India, nearly 20% of liver injury cases are linked to drugs and supplements. Signs of liver stress include jaundice, nausea, and persistent fatigue. A balanced diet rich in whole foods is recommended to support liver health, alongside mindful supplementation and regular consultations with healthcare professionals. This approach ensures fitness goals are achieved without compromising health.
