LETS TALK ABOUT HOW IMPORTANT VITAMIN D IS FOR OUR BODY!

While we are slowly moving into the winter months where the days are shorter and we spend a large majority of our days in reduced light, it is important to note the impact that this can have on our body.
_
Today I am going to talk about Vitamin D and its importance for an optimal functioning body.
_

A lack of Vitamin D affects almost over 50% of the population worldwide. This is mainly attributed to lifestyle and environmental factors that reduce our skin to sunlight exposure (Holick, 2007). This can cause a lot of issues because vitamin d is synthesised when then the skin is exposed to the sun and only a small amount can be obtained from our diet.

According to Nair and Maseeh (2012) “vitamin D can play a vital role against cancer, heart disease, fractures and falls, autoimmune diseases, influenza, type-2 diabetes, and depression”.
_
Wang et al. (2009) noted that patients with lower levels of vitamin d had a 60% increased risk of heart disease in comparison to those with higher levels.
_

Jorde et al (2008) showed that subjects who were administered at a very high dose of vitamin D had a significant improvement on depressive symptoms over the duration of 1 year.
_
Vitamin D helps the body absorb calcium, therefore there is an increased risk of fractures during falls in older people with low vitamin d levels (Liebman, 2009).
_

According to Bjelakovic et al. (2011) higher serum levels of vitamin d are associated with lower rates of all causes of mortality, possibly due to the fact that there are less subsequent falls and less hospitalization which may lead to deaths.
_
Finally, vitamin D showed an improvement in upper and lower limb strength when the subjects supplemented for up to 6 months (Tomlinson, Joesph & Angioi, 2015).

Things you need to know and can take action on from reading this article:
_
How and When?
_
1. It is a fat-soluble vitamin; therefore, it should be consumed with a fat-containing meal to help with absorption.

  1. I would recommend to get a blood test done and then supplement accordingly.
  2. 2500-4000iu is recommended.
  3. Supplementation is far more effective than trying to consume it via the diet, but sun exposure is the best (here in Ireland we are limited so supplementation may be needed all year round).
