Vitamin D is a nutrient made by the body when the skin is exposed to sunlight and acquired through diet, mainly by eating fish and fortified foods. Vitamin D is critical to the body's ability to absorb calcium through the intestines and regulating the body's balance between calcium in the bloodstream and calcium in the bones. A Vitamin D deficiency may cause bones to weaken and easily fracture. Vitamin D is sold over-the-counter in supplements as either vitamin D2 or vitamin D3. Vitamin D is prescribed to address vitamin D deficiency or treat an underactive thyroid. Vitamin D's generic retail price averages $13.89 for 90, 50 mcg(2000 ut) tablets, but a SingleCare Vitamin D coupon lowers this cost to $6.13 for 90, 50 mcg(2000 ut) tablets. You can use your SingleCare Vitamin D coupon on over-the-counter supplements, like Vitamin D, with a doctor's prescription.

Vitamin D is a nutrient made by the body when the skin is exposed to sunlight and is also found in fish and fortified foods. Vitamin D helps the body absorb and use calcium and phosphate, substances that are the building blocks of bones and important to many other processes in the body, particularly the nervous system. Vitamin D also helps the body maintain the right balance of calcium and phosphate in the body.
Vitamin D deficiency is common, particularly in children or adults who do not get much sun exposure. A Vitamin D deficiency in children causes bones to become weak and flexible (rickets) and will cause bone softness (osteomalacia) in adults. For this reason, many foods, such as milk and processed foods, are fortified with additional Vitamin D. Otherwise, Vitamin D deficiency is treated with over-the-counter or prescription supplements.
In addition to treating Vitamin D deficiency, Vitamin D is often advised or prescribed to patients with osteoporosis, or bone loss, along with calcium and phosphate supplements, to help increase bone density. Vitamin D is also prescribed to treat hypoparathyroidism or underactive thyroid.
As a supplement, Vitamin D usually comes in the form of vitamin D2 (ergocalciferol) and D3 (cholecalciferol). The difference between the two is that D2 is produced by exposing plant sterols to ultraviolet light and D3 is manufactured by exposing animal fats and cholesterol to ultraviolet light. Both are biologically inactive and can be converted by the body to produce biologically active vitamin D. Vitamin D2 is cheaper to manufacture than D3 and so is the most common ingredient in vitamin D supplements.
In the body, ultraviolet light in sunlight drives the conversion of a form of cholesterol into cholecalciferol (D3). That molecule is then chemically changed by the liver. This is the form of vitamin D that is measured to determine the body's vitamin D levels to determine vitamin D deficiency. However, that form of vitamin D is also biologically inert. It must be converted to the active version of vitamin D, called calcitriol, by the kidneys. Calcitriol is the form of vitamin D that is prescribed to patients with kidney disease to address a deficiency of biologically active vitamin D.
Vitamin D1 does not exist. Vitamins D4 and D5 are recently discovered or invented forms of vitamin D and do not currently have any medical uses.
Vitamin D is available in many over-the-counter vitamin supplements both individually and in combination with other nutrients. As a supplement, Vitamin D is administered as a capsule, gelcap, or injection. Prescription Vitamin D is most commonly cholecalciferol (D3). Calcitriol is administered as an injection or capsule.
As a naturally occurring molecule in the body and many foods, Vitamin D does not have significant side effects. However, Vitamin D supplements often have other inactive ingredients, so allergic reactions to Vitamin D supplements may happen in some people. These side effects include itching, rash, hives, eye pain, trouble breathing, or headache. If you have any reaction to Vitamin D supplements, stop taking the supplement and consult with your physician.
