D most important vitamin? No comments yet

General Health

New evidence shows that people with higher levels of vitamin D experience a decreased risk of type 2 diabetes, have higher activity in the body’s immune system against infectious diseases like flu and also have better balanced moods and energy levels. Vitamin D  also helps build healthy bones, hearts, nerves, skin and teeth, and it supports the health of the thyroid gland, maintaining healthy weight and a balanced metabolism.

Whilst moderate sunlight exposure is the best source of vitamin D, many people incorrectly think that a small amount of sunshine exposure daily is sufficient to meet their vitamin D needs. However, after your skin is exposed to sunlight, it takes about 48 hours to convert it into vitamin D.  During that time, the sunlight-initiated precursors to vitamin D can be washed off with soap and water. So if you scrub your skin with soap in the shower, your body will not convert most of your skin’s sun exposure to vitamin D.

This leaves us in a quandary. Whilst vitamin D can be found in many foods, like oily fish, sweet potatoes, sunflower seeds, mushrooms and many other sources, it is in fairly low amounts and not that easily absorbed. This is where a good vitamin D supplement comes in!

Many nutritional experts agree that the current RDA of 5µg (200iu) is insufficient and should be more like 25µg. However, we do think this may be a little excessive, but regularly recommend 10µg on a daily basis for better health!

Pregnancy

A team at University College London Institute of Child Health say that there is a very “strong case” for a daily dose of vitamin D in pregnancy to go alongside the 400µg of Folic Acid currently recommended.

The Department of Health advises pregnant women to ensure they receive a certain level of vitamin D – 10µg per day. The researchers say this in effect endorses the use of supplements, because diet and the sun provide too little. Women should be informed about the importance of having adequate vitamin D levels during pregnancy and whilst breast feeding.

It is worth noting here that pregnant women on low incomes are entitled to a range of nutrients – including vitamin D – as part of the Healthy Start Scheme.

Dr Elina Hypponen, co-author of the paper, said “The incidence of vitamin D deficiency in pregnant women in Britain is unacceptably high, especially during winter and spring”. The paper also said that the UK was the only one of 31 countries examined which did not recommend that women of reproductive age took a vitamin D supplement, and that it also failed to endorse a daily supplement for expectant mothers. “We believe that the routine provision of a daily supplement throughout pregnancy would significantly decrease the number of mothers who are clearly vitamin D deficient, reducing related serious risks to their babies.”

If pregnant, thinking of becoming so, or breast feeding we would recommend good all-round nutrition in the guise of our Pregnancy Formula!

“Vitamin D Supplementation in the UK might be beneficial for the whole population.”, Mr Patrick O’Brien, RCOG.
