Vitamin D is a hormone that controls calcium levels in the blood. Vitamin D is needed for strong bones, muscle strength and overall health.
We naturally receive Vitamin D AKA 'the sunshine vitamin' from the sun's ultraviolet radiation, however, Vitamin D is also present in some food sources e.g. fish, eggs.
Vitamin D deficiency can include bone and muscle pain, and softening of the bones – such as rickets (in children) and osteomalacia (in adults). If you are concerned about your vitamin D levels, seek advice from your GP and they may advise supplementing Vitamin D. If you are just concerned about not receiving as much Vitamin D as you should e.g. having an inside job, live in a colder climate - Vitamin D would be a great supplement to add to your diet.
