Vitamin D is essential in aiding the growth and development of children as well as being an important component for bone and tooth health since it helps with calcium and phosphorus absorption and use. When used with a healthy diet and exercise, vitamin D can help the body's natural process of producing new cells as well as maintain healthy muscles and joints. Vitamin D also plays a role in the division of cells. During the colder months, it is likely that some may experience vitamin D deficiency, which can show in a multitude of ways, which is why vitamin D supplementation is so commonly recommended no matter what your age is.
It circulates in the bloodstream to help in the absorption of calcium and phosphorus in the body. It does this by transforming into a hormone in the body and can be classed as one of the most vital functions that Vitamin D3 performs.
The recommended daily adequate intake is 600-800 IU a day but the maximum intake is 4,000 IU a day. This can depend on your requirements, including your body type, age and exposure to sunlight. As well as how long you are planning to take it.
The main difference is how they are made. Vitamin D is made from plants, the most common example is wild mushrooms or mushrooms that have been produced under UV light whereas Vitamin D3 is most commonly found in humans and animals for e.g oily fish like salmon or mackerel. It is produced in the body's skin when exposed to sunlight.
