Vitamin D is very important to the folks that live in the northern climes.  I didn’t know much about it until I was diagnosed with a deficiency of vitamin D.  Vitamin D comes from the sun when exposed to the sun and its ultraviolet light or radiation.   It also comes from supplements, fortified foods, eggs, liver, and fish.  The calcium that we need to keep our joints moving in a smooth efficient manner requires a regular dose of vitamin D. Vitamin D is fat soluble, and is stored in the fat.  We constantly use vitamin D for calcium metabolism and bone building.

I am lactose intolerant so I usually don’t drink milk or consume dairy products.  Living in Minnesota during winter, with no dairy and no sun triggers creaky joints and makes life miserable. Too little Vitamin D will cause pains and muscle weakness. Extreme deficiency can cause Rickets, causing soft bones and deformities. Get your vitamin D.

Extreme deficiencies of vitamin D can cause cancers, asthma, cardiovascular diseases, and autoimmune diseases. Dark skin has decreased ability to synthesize vitamin D in sunlight.  The skin pigment, melanin, has been shown to inhibit production of vitamin D by the skin. Obese people may have deficiencies because fat cells extract vitamin D from the blood.  On top of all this, too much vitamin D can be toxic.

What is the right amount of vitamin D for the average Joe?  A daily multi-vitamin supplement will have the proper amount, usually 600-800 milligrams. Get your vitamin D.
