Vitamin D is a crucial nutrient that plays a vital role in maintaining overall health. It is unique because it acts like both a vitamin and a hormone in the body. Here are some key reasons why vitamin D is important:

• Bone Health: Vitamin D helps the body absorb calcium, which is essential for building and maintaining strong bones. Without sufficient vitamin D, bones can become thin and brittle.

• Immune Support: It enhances the pathogen-fighting effects of monocytes and macrophages—white blood cells that are important parts of your immune defence—and decreases inflammation.

• Mood Regulation: Adequate levels of vitamin D are associated with improved mood and mental health. Low levels have been linked to conditions like depression.

• Muscle Function: Vitamin D contributes to muscle strength, reducing the risk of falls and fractures, especially in older adults.
