Protein intake is especially important for males around the age of 50 who engage in gym training due to age-related muscle decline and the increased protein needs associated with exercise. Here are some key points based on current research:

1. Muscle Mass and Strength: Consuming protein supplements can significantly aid in increasing muscle mass and strength, particularly when combined with resistance training. Studies have shown that older men benefit from daily protein supplementation, which leads to gains in lean body mass and muscle strength¹².

2. Sarcopenia Prevention: After the age of 40–50, males start experiencing sarcopenia, the age-related loss of muscle mass. Increasing protein intake to about 1.0-1.2 grams per kilogram of body weight can help prevent muscle loss and maintain physical independence³. For a 75 kg male, this translates to 75–90 grams of protein daily.

3. Protein Timing: To maximize the benefits of protein, it should be evenly distributed throughout the day. Consuming 15–30 grams of protein at each meal is advisable. This not only aids in muscle synthesis but may also assist in weight management by reducing hunger and cravings³.

4. Types of Protein: Whey protein is particularly effective due to its high leucine content, which stimulates muscle protein synthesis. Other helpful supplements include creatine, vitamin D, calcium, and omega-3 fatty acids. These combined can enhance muscle and strength gains even further¹⁴.

5. Overall Health: While protein is essential, it's important not to exceed the recommended amount, typically not more than 2 grams per kilogram of body weight. Excess protein can pose risks such as kidney strain and cardiovascular issues³⁵.

By focusing on the right amount and timing of protein intake, males around the age of 50 can improve their muscle health and performance in the gym.
