Vitamin D, the ‘Sunshine Vitamin’

Vitamin D is commonly known as the sunshine vitamin as the human body produces vitamin D when exposed to sun, but it can be found in a variety of food sources too.

Vitamin D regulates the levels of calcium and phosphate in the body, which is important for healthy bones and teeth and it also supports the health of the brain, nervous and immune systems. Studies have shown Vitamin D may also help to regulate insulin levels, aiding management of diabetes, provide protection against cancer and prevention and treatment of inflammatory skin diseases. https://www.ncbi.nlm.nih.gov/pubmed/17326003

Who is more at risk from vitamin D deficiency:

It is estimated that 1 billion people have vitamin D deficiency or insufficiency worldwide (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4143492/, https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3068797/ ), common risk factors include:

  • Elderly
  • Dark skin.
  • Overweight or obese.
  • Not eating much fish or milk.
  • Always using sunscreen.
  • Being indoors.

What are the signs of Vitamin D deficiency?

The signs of vitamin D deficiency are very subtle and may not be noticed easily. The following are signs and symptoms of vitamin D deficiency:

How do I know if I am vitamin D deficient?

Symptoms of low vitamin D levels are often subtle and non-specific which make it hard to be sure it’s a deficiency and not something else.  To be sure, you can speak to your doctor and ask for a blood test or visit a Nutritional Therapist who can perform a vitamin D testing service.

How can I increase my vitamin D levels?

Sunlight is the most common and efficient source of vitamin D; it is estimated that sensible sun exposure on bare skin for 5-10 minutes 2-3 times per week allows most people to produce sufficient vitamin D.  Other ways of increasing vitamin D are by eating certain types of food (certain types of oily fish, fish oil, eggs, chicken, mushrooms) or by taking vitamin D supplements. A Nutritional Therapist can advise you on the optimum foods to include in your diet to improve vitamin D levels and also on taking supplements.

"I met Fiona at a networking event about two years ago where she was giving a talk on Colon Hydrotherapy, and was immediately impressed with her knowledge and quiet, calm manner. I have been seeing Fiona for nutritional advice and regular colon hydrotherapy treatments ever since and highly recommend her. (I had been looking for someone to go to for colonics for years, and was very happy to finally find someone I felt comfortable with). Fiona gives regular talks to groups and offers her excellent treatments in Tunbridge Wells, Battle and Hastings.  She works to a very high professional standard and is gentle, caring and sensitive. I recommend her to many of my own clients as I feel that nutrition and colon hydrotherapy is so key to overall health and well being - certainly critical to skin condition!"
