Vitamin D is important for good health, growth and strong bones. A lack of vitamin D is very common. Vitamin D is mostly made in the skin by exposure to sunlight. Most foods contain very little vitamin D naturally, though some are fortified (enriched) with added vitamin D. A mild lack of vitamin D may not cause symptoms but can cause tiredness and general aches and pains. A more severe lack can cause serious problems such as rickets (in children) and osteomalacia (in adults), described below. Treatment is with vitamin D supplements. Some people are more at risk of vitamin D deficiency, and so are recommended to take vitamin D supplements routinely. These include all pregnant and breastfeeding women, all infants (babies) and young children aged 6 months to 5 years, people aged 65 and over, and people who are not exposed to much sun. A doctor may also recommend routine supplements for certain people with darker skin, and for people with certain gut, liver or kidney disease.

The table below gives you an indication of the treatment pathway depending on your current blood level of Vitamin D.
To treat low Vitamin D levels we advise buying Cholecalciferol capsules 1000iu. The capsules can be brought from any pharmacy. Please ask for the value pack, or similar. After 3 months treatment we can then recheck your levels by repeating the blood test.
