Why Do Older Adults Benefit from Protein Powder Supplementation?

Appetite, chewing ability and digestive function gradually decline with age, leading to widespread insufficient protein intake among the elderly. Supplementing with protein powder plays an important role in maintaining senior health.

1. Protein Intake Is Generally Inadequate for Seniors

Nutrition surveys show that around 76% of Chinese adults aged 65 and over fail to meet the recommended protein intake, with an average daily intake of only 58 grams.

According to the Dietary Reference Intakes for Chinese Residents (2023), older adults need 1.17 g of protein per kilogram of body weight every day. For a 60 kg senior, the daily protein requirement is more than 70 grams. Long-term protein deficiency will cause muscle loss and reduced physical ability.

2. Protein Powder Is Easy to Digest and Absorb

Common protein foods like meat and eggs take 3 to 4 hours for gastric emptying. Whey protein powder dissolves quickly with small molecular particles, and only needs 1 to 2 hours to empty from the stomach. Its amino acid absorption speed is over 40% faster than regular dietary protein.

The secretion of digestive enzymes in seniors is 20% to 30% lower than young adults. Protein powder requires no complicated chewing and will not burden the digestive system.

3. Protein Helps Prevent Age-Related Health Problems

• Adequate protein intake reduces the risk of sarcopenia by 42% and lowers the chance of falls and fractures.
• It boosts the activity of immune cells and cuts the incidence of respiratory infections by about 35%.
• It slows bone loss, protects blood vessels and organs, and reduces the risk of chronic disease complications.
