Vitamins and minerals are essential for good health. Each of these nutrients has a specific role to play in maintaining our body functions. One such vitamin is Vitamin D.
What is Vitamin D?
Vitamin D is a fat-soluble vitamin that our body needs to maintain healthy bones and muscles. It also plays a crucial role in the absorption of calcium in the body. Unlike other vitamins, our body produces Vitamin D naturally.
Our skin produces Vitamin D when exposed to the sun’s ultraviolet B (UVB) rays. Besides, we can also get Vitamin D from certain food sources and supplements.
What are the types of Vitamin D?
There are two main types of Vitamin D:.
- Vitamin D2: It is also known as ergocalciferol. It is found in plant-based foods such as mushrooms and fortified foods like cereal, milk and orange juice.
- Vitamin D3: It is also known as cholecalciferol. It is produced by our body when exposed to UVB rays. It is also found in animal-based food sources such as fatty fish, egg yolks, and liver.
Why is Vitamin D essential for our body?
Vitamin D is a crucial nutrient that our body needs to maintain several essential functions. Let’s take a look at the benefits of Vitamin D:.
: 1. Helps maintain healthy bones
Vitamin D helps in the absorption of calcium and phosphorus from food, which is crucial for maintaining healthy bones. It also plays a key role in preventing conditions like osteoporosis and rickets.
: 2. Promotes healthy muscles
Vitamin D plays a vital role in the health of our muscles. It helps improve muscle strength and function. It also helps reduce the risk of falls in older adults.
: 3. Supports the immune system
Vitamin D helps boost the immune system by promoting the production of antimicrobial peptides. It also helps reduce inflammation, which is essential for fighting infections.

Vitamin D helps regulate insulin levels and improve insulin sensitivity, which is beneficial for people with diabetes.
How much Vitamin D do we need?
The recommended daily intake of Vitamin D varies by age, gender and health status.
The UK’s National Health Service (NHS) recommends the following daily intake for different age groups:.

- Children (1-10 years): 10mcg/day
- Adults (11-70 years): 10mcg/day
- Adults (70 and above): 20mcg/day
People with certain health conditions such as osteoporosis, rickets and malabsorption may require higher doses of Vitamin D. However, it is advisable to consult a healthcare provider and get your Vitamin D levels checked before taking any supplements.
