Signs indication you may have a Vitamin D deficiency include having dark skin, obesity, achy bones, feeling blue, over the age of 50, head sweating and poor immune function. Your best bet is to get your Vitamin D levels tested twice a year. The optimal range for general health appears to be somewhere between 50 and 70g/ml.
Get some sensible sun exposure. Contrary to popular belief the best time to be in the sun for Vitamin D production is actually as near to solar noon as possible – but keep it short. UVB rays are most tense at this time. When the sun goes down towards the horizon, the UVB is filtered out much more that the dangerous UVA.
Vitamin D rich food and D3 supplements may also be necessary if you cannot get adequate sun exposure during the year.
And did you know Glyphosate (round-up) has being shown to interfere with enzymes responsible for activating Vitamin D in your liver and kidneys. We found that most patients with hair loss have a Vitamin D deficiency when blood tests are done.
