Protein After 40: Why It Matters

Protein is essential at every age — but after 40, it becomes one of the most important nutritional levers you have for maintaining muscle, supporting metabolism, and managing body composition.

Sarcopenia: The Silent Muscle Loss

Starting in your 30s, adults can lose 3–8% of muscle mass per decade without adequate protein and resistance training. This process, called sarcopenia, accelerates after menopause due to declining estrogen. Muscle loss affects metabolism, strength, balance, and long-term independence.

How Much Protein Do You Actually Need?

Current research suggests women over 40 benefit from 1.2–1.6g of protein per kilogram of body weight daily — significantly more than the outdated RDA of 0.8g/kg. Spreading intake across meals (30–40g per meal) optimizes muscle protein synthesis.

Best Protein Sources

• Whey protein — fast-absorbing, high in leucine, ideal post-workout
• Collagen peptides — supports connective tissue and joint comfort
• Plant-based blends — pea + rice protein for complete amino acid profiles
• Whole food sources — eggs, Greek yogurt, fish, legumes
