As we age, calcium loss accelerates, muscle mass declines, and digestive absorption weakens, so the same diet delivers progressively fewer nutrients. The focus of mature-age care is targeted supplementation rather than high-dose supplementation.
Four Key Nutrients
- Calcium and vitamin D: the gold standard for bone health. When vitamin D is insufficient, calcium absorption may fall below 30%, and a daily supplement of 800–1000 IU is recommended.
- High-quality protein: central to preventing sarcopenia. Recommended intake is 1.0–1.2g of protein per kilogram of body weight per day, distributed evenly across three meals.
- Omega-3 fatty acids: support cardiovascular function and mobility; aim for at least two servings of deep-sea oily fish per week or daily fish oil supplementation.
- Vitamin B12: reduced gastric acid with age can impair B12 absorption, so vegetarians and vegans should pay particular attention.
Three Lifestyle Habits
First, weight-bearing exercise: brisk walking or light resistance training for 30 minutes per session, three times a week, effectively stimulates bone and preserves muscle strength. Second, adequate sunlight: 15 minutes of daily sun exposure supports vitamin D synthesis. Third, regular screening: annual bone density and blood biochemistry tests to tailor supplementation strategies based on objective data.
Healthy aging is not about consuming the most, but about providing the body exactly the support it needs where it needs it. It's never too late to start.
