V I T A M I N D
Blinking in the sunshine… I’ve been loving the warm autumn we’ve been having so far and so has my body.
Our main source of vitamin D is the sun – ultraviolet B radiation from sunlight can be synthesised by vitamin D3, the active form of Vitamin D, when exposed on the skin.
Vitamin D is vital for our health. It promotes calcium absorption in the intestine and maintains calcium and phosphate levels in the blood, protecting against osteoporosis, rickets, and bone fracture. It also regulates your immune system, cell growth, and improves brain development and function.
Because of our increased ‘indoor’ lives and especially in the long winter months, many people are thought to be deficient in Vitamin D.
Extreme deficiency can lead to issues such as rickets in children and osteomalacia in adults and may increase the risk of heart attack, cancer, diabetes, asthma, and autoimmune disease
Other signs of not getting enough vitamin D can manifest in decreased immune function such as low mood, constant coughs and colds, tiredness and fatigue, SAD, poor bone and tooth health.
But that doesn’t mean going gung-ho with supplements is the answer. Although it is likely you may need to supplement at some point over the winter, Vitamin D is a fat soluble vitamin which your body can store effectively for some time. EVERYONE is biologically unique in how much they need and can absorb so knowing your own needs is important.
Too much of a good thing…
Because we store Vitamin D in our bodies, it does mean we can have too much. Too much vitamin D can lead to toxicity – this can result in hypercalcaemia heart attack, stroke, kidney stones, headache, nausea, vomiting, diarrhea, anorexia, weight loss, and low bone density.
With the awareness of vitamin D and it’s benefits, many doctors are happy to test levels before you supplement. You can also get an online test at http://www.vitamindtest.org.uk (I’ve got mine!) In fact now would be the perfect time to get tested as your levels SHOULD be at their highest after our gorgeous summer sun.
Once tested I like to use BetterYou oral spray – it’s super easy to use!
Vitamin D is quite difficult to get through diet alone but having healthy fats in your diet (and with your supplement) is important for absorption.
Key food sources of Vitamin D:
Oily fish; salmon, sardines.
Some mushrooms (but only if grown in sun light)
Get in that sun whilst you can!
