Vitamin D3 4000iu (100µg)

In the UK, the only significant food source of vitamin D is oily fish. Most of our vitamin D comes from the sun. But there is a problem: many people in the UK never get what they need from sunlight alone because sunlight's ability to help us produce vitamin D is hampered by:

•  Season (it only works in the summer)
• Latitude (the UK is pretty far north)
• Time of day (needs to be between 11am and 3pm)
• Cloud cover (complete cloud cover reduces vitamin D synthesis by 50%)
• Smog/pollution (most of us live in cities)
• Skin melanin content (the darker skinned you are, the less vitamin D you'll get from the sun)
• Sunscreen (SPF of 8 and above).

Even in summer, when vitamin D is most available, it is estimated that 45% of the English population have vitamin D levels of less than 40nmol/L (deficient) and that 75% fail to reach the 'optimal' level of 75nmol/L.

The natural Vitamin D3 in this product is the same form produced by the body when the skin is exposed to sunlight.
