Vitamin D is a fat soluble vitamin. D works with vitamin A to utilize calcium and phosphorus in building bones and teeth. Although we call it a vitamin, D is really a hormone produced in the skin from sunlight. Cholesterol compounds in the skin convert to a vitamin D precursor when exposed to UV radiation. Twenty minutes a day of early morning sunshine make a real difference to our body's vitamin D stores, especially if you are at risk for osteoporosis. Vitamin D helps in all eye problems including spots, conjunctivitis and glaucoma. Helps protect against colon cancer. Deficiency results in nearsightedness, psoriasis, soft teeth, muscle cramps and tics, slow healing, insomnia, nosebleeds, fast heartbeat and arthritis.
