Vitamin D

Vitamin D is a fat-soluble vitamin that is essential for the absorption of calcium and maintaining strong, healthy bones. It also plays a crucial role in supporting the immune system, muscle function, and overall health.

Sources of Vitamin D

The primary source of vitamin D is sunlight. When the skin is exposed to sunlight, it produces vitamin D. Additionally, vitamin D can be obtained from certain foods such as fatty fish (like salmon and mackerel), cheese, egg yolks, and fortified dairy products and cereals.

Importance of Vitamin D

• Promotes calcium absorption for bone health
• Supports immune system function
• Regulates mood and reduces the risk of depression
• Helps in maintaining muscle function
• Plays a role in overall health and well-being

Deficiency and Health Risks

A deficiency in vitamin D can lead to health issues such as rickets in children, osteomalacia in adults, weakened immune system, increased risk of cardiovascular diseases, and a higher likelihood of experiencing bone fractures and muscle weakness.

Recommended Intake

The recommended daily intake of vitamin D varies by age and gender. Infants, children, adolescents, and adults have different recommended dietary allowances for vitamin D. It is important to consult with a healthcare professional to determine the appropriate intake for individuals based on their specific needs.
