Essential Nutrients for Muscle Maintenance

The general recommendation for muscle maintenance is 0.7–1.0 grams of protein per pound of body weight daily, depending on training intensity and age. This ensures adequate amino acids for muscle protein synthesis and recovery. Individuals over 65 may benefit from slightly higher intake to counter age-related muscle loss. Individual needs vary based on training type, genetics, and overall health status.

Consuming carbohydrates and protein 2–3 hours before exercise provides energy for performance. A smaller snack (fruit + yogurt) 30–60 minutes pre-workout suits some individuals. Post-workout, consuming protein and carbs within 1–2 hours supports recovery and muscle adaptation. However, overall daily nutrient intake matters more than precise meal timing for most recreational athletes.

A well-planned diet with whole foods—lean meats, eggs, legumes, whole grains, fruits, and vegetables—provides most essential nutrients. However, certain situations warrant supplementation: vitamin D in low-sunlight climates, B12 for vegans, or creatine monohydrate for performance. Consult health professionals to identify personal needs and ensure optimal nutrient status.

Magnesium regulates muscle contraction and relaxation by controlling calcium movement. Calcium is essential for muscle contraction force and bone strength. Potassium maintains fluid balance and supports muscle signalling. Deficiencies in these minerals can cause cramping, weakness, and impaired performance. Adequate intake from foods like leafy greens, dairy, nuts, and bananas is crucial.

Intense exercise increases reactive oxygen species, causing muscle damage and inflammation. Antioxidants like vitamins C and E, selenium, and polyphenols neutralise these compounds, reducing inflammation and supporting faster recovery. Found in berries, citrus, nuts, and green tea, adequate antioxidant intake helps muscles repair and adapt more efficiently to training stress.
