Vitamin D: The Sunshine Vitamin Your Body Needs

Vitamin D supports bone strength, immunity and mood — yet deficiency is one of the most common nutrient gaps worldwide.

Why it matters

It helps absorb calcium and supports immune defenses. Low levels are linked to fatigue, bone pain and frequent infections.

How much do you need?

Most adults need 600–2000 IU daily; your pharmacist or doctor can test your level and advise.

Sources

• Sunlight — 10–30 minutes several times a week
• Fatty fish, fortified dairy, egg yolks
• Supplements — vitamin D3 1000–5000 IU
