What is vitamin D3?

Vitamin D3 is a naturally occurring vitamin produced by the body during exposure to sunlight. Vitamin D synthesis by sun exposure is responsible for the majority of vitamin D absorption in the body. It is therefore recommended that supplementation is necessary during the winter months, where sunlight exposure is limited, to compensate for the limited production of D3 from sunlight and to meet recommended levels.

There are two types of vitamin D, D2 and D3. While D2 is produced by plants and can be consumed through food, D3 is available in very few foods but can be synthesised by the skin. Vitamin D3 can be found in foods such as oily fish, milk and eggs, although it is almost impossible to meet your daily needs through food alone.

Surprisingly, vitamin D3 is one of the most common deficiencies, especially during the dark winter months. Although it is estimated that we need about 30 minutes of sun exposure on bare skin for sufficient vitamin D synthesis, vitamin D breaks down very easily and our stores can quickly run out.

We need an estimated 30 minutes of sun exposure on bare skin to achieve sufficient vitamin D synthesis. Not surprisingly, vitamin D3 is one of the most common deficiencies, especially during the dark winter months. Vitamin D is also very easily broken down, meaning that our stores can run out quickly and need to be replenished. That said, the much-publicised health risks associated with sun exposure mean that avoiding the sun and wearing sunscreen daily has become a necessity for many health- and skin-conscious people.

There is also evidence that, particularly in England, vitamin D3 needs to be supplemented year-round to meet recommended levels.

Who is vitamin D3 intended for?

Vitamin D3 is for anyone who wants to cover all the basic needs needed to maintain their health. If much of your skin is not exposed to the sun for at least 20 minutes daily, you should consider supplementation. Darker skin tones are also at risk of deficiency due to a reduced ability to absorb UVB rays from the sun that are needed to produce vitamin D. NHS guidelines in the UK recommend that anyone with darker skin should consider supplementation.
