How to reduce your risk of diabetes and a heart attack during the summer heatwave

What are the best ways of getting the right dosage of vitamin D?

During the summer months, the most effective way is to head outside as the body produces the vitamin D from sunlight. Once enough vitamin D has been produced, no more will be made.

However, between the months of September and April, the body can’t produce enough from sunlight. In this case, either supplements or dietary changes are required.

Key sources of vitamin D in food include:
• Oily fish
• Red meat
• Liver
• Egg yolks
• Fortified food.

Meanwhile, the NHS warms that “UK cow’s milk is generally not a good source of vitamin D because it is not fortified, as it is in some other countries”.
