Unlike other nutrients, vitamin D is produced by the body in the presence of sunlight; hence it’s nickname, ‘the sunshine vitamin’. Whilst toxic in higher doses, vitamin D is essential for bone growth and maintenance, as well as protein synthesis, and therefore 10 micrograms per day is recommended for healthy adults. There are very few good dietary sources of the vitamin, but oily fish and dairy can boost the body’s reserves, especially during winter months when the sun’s rays aren’t powerful enough to stimulate vitamin D production in the skin.
Should I take a vitamin D supplement?
If you don’t eat oily fish or dairy and are rarely able to expose your skin to 15 minutes of sunlight during summer months, a vitamin D supplement is advisable. However, make sure you read the label carefully and do not take more than 10 micrograms per day.
