Vitamin D

21/2/2011

Sloane Medical Practice has recently added Vitamin D levels to their routine female health check.  We have found that low Vitamin D levels are particularly common especially in the over 65s.

Vitamin D is a fat soluble vitamin which is derived mainly from sunlight in the form of UVB exposure (90%).  Its main function is to allow the body to absorb calcium and keep the right levels of calcium and phosphorus in the blood which is essential for healthy bones.  It is also used to keep nerves and muscles working properly.

Low Vitamin D levels increases risk of the following conditions:

• Osteoporosis (thinning of the bones)
• Breast and colon cancer
• Multiple Sclerosis (degenerative neurological condition)
• Type 2 Diabetes
• Cardiovascular disease (heart attacks, strokes)
• Depression

Vitamin D levels can be corrected by taking 15-20 minutes of unprotected sunlight exposure daily between May-October in the UK or by taking 800-1000iu daily of Vitamin D3 supplements.  Some Vitamin D3 is incorporated into calcium supplementation but unless calcium is warranted, it is advisable just to take Vitamin D3 on its own.  Increasing consumption of foods rich in vitamin D such as margarine, egg yolk, cereals and mushrooms would also be beneficial.

Vitamin D supplementation should be considered in pregnancy, particularly in the third trimester, as low levels of maternal Vitamin D correlate to low bone density in  children up to the age of 9. Vitamin D levels are not routinely checked during pregnancy at the moment.

If you have any questions, please contact the practice for an appointment.
