Seniors (50+): Increased fractures, falls, balance issues, cognitive concerns

⚠️ Common Risk Factors

Limited sunlight exposure
Darker skin pigmentation
Aging (reduced skin synthesis)
Vegan or dairy-free diets
Obesity or weight-loss surgery
Digestive issues (e.g., Crohn’s, celiac)
Certain medications (steroids, anti-seizure drugs)

🦴 Consequences of Long-Term Deficiency

Rickets in children
Osteomalacia or osteoporosis in adults
Frequent falls and bone fractures
Weakened immune defense
Reduced quality of life

☀️ How to Prevent Vitamin D Deficiency

✅ Get Some Sunlight

Aim for 10–30 minutes of midday sun (face, arms) several times a week—more for darker skin tones or in winter.

✅ Eat Vitamin D–Rich Foods

Fatty fish (salmon, tuna, sardines)
Egg yolks
Fortified milk and cereals
Mushrooms exposed to UV light

✅ Take Supplements (if needed)

Most adults benefit from 600–2000 IU/day of vitamin D₃. Seniors or those with confirmed deficiency may need higher doses under doctor supervision.

🩺 When to Test for Deficiency

If you experience ongoing fatigue, bone pain, frequent infections, or are in a high-risk group, ask your healthcare provider for a simple blood test to check your vitamin D levels.

Stay well with the power of vitamin D.
Balance sunlight, food, and supplements to support your whole-body wellness from bones to brain.
