Vitamin D
Your skin synthesizes less vitamin D from sunlight as you age, while your kidneys become less efficient at converting it into its active form. This shortfall directly threatens your bone density and increases fracture risk.
Include fatty fish like mackerel and sardines in your weekly meal rotation to naturally boost your intake. You can also rely on fortified dairy products and UV-exposed mushrooms to fill dietary gaps, ensuring you maintain optimal levels regardless of seasonal sunlight changes.
