Vitamin D might not seem to be an important element of joint and bone health, but without it, calcium cannot be adsorbed and utilized properly by your body, so make sure your calcium supplement contains vitamin D in addition to calcium. Vitamin D is a fat soluble vitamin, which means that it needs some dietary fat to adsorb into the body. Vitamin D is created in the liver and kidneys, but it can also be made within the body by exposure to the ultraviolet rays of the sun.

Vitamin D is also essential in the body because it helps maintain normal blood levels of calcium and phosphorous, which are some of the essential minerals for good bone and body health. A deficiency of vitamin D can lead to rickets and lower calcium levels, among other ailments. Vitamin D is found in most dairy products, and many types of fish, including salmon, tuna, sardines, and mackerel.

The sun’s UV rays prompt the skin to synthesize vitamin D3, an essential vitamin required for calcium absorption and utilization. Ultimately, vitamin D3 is important for the health of bones, teeth, eyes, and joints, and is responsible for immune functions.

Vitamin D3 supplements are available for those who don’t get enough sun, are concerned with the adverse effects of too much sun, or have dark skin as dark-skinned individuals often do not produce as much vitamin D3 as those with light skin. Here are a few options to consider when choosing a vitamin D3 supplement:

* Vitamin D3: This supplement is great for individuals at risk for a vitamin D3 deficiency, which experts believe can lead to heart disease, chronic pain, arthritis, depression, cancer, autoimmune disorders, and many other afflictions. It’s also good for the elderly who need extra protection from calcium-related conditions like osteoporosis.
* Vitamin D3 and K2: Check out substances that that have D3 and K2 together, which can help with healthy bone and cartilage growth. It also helps with promoting healthy blood vessels, which is important to cardiovascular health.
* Vitamin A, D and Fish Oil: These vitamins work together to promote healthy bones, teeth and eyes. They also contain oils, which fat-soluble vitamins need to absorb correctly.

Vitamin D overdose does not occur very often, but it does happen, so it pays to be aware of the symptoms and what can cause vitamin D overdose. Too much vitamin D in the body can cause high blood pressure, and it can also cause nausea, vomiting, and lack of appetite. Excessive urination and thirst are also symptoms, and if left untreated it can lead to kidney failure.

A vitamin D overdose in the body is usually caused by long-term exposure in factories or industrial accidents. Too much exposure to the sun does not cause vitamin D overdose, no matter what some people believe. Vitamin D overdose can also be caused by too much calcium in the blood, so the two supplements are related. If you are diagnosed with vitamin D overdose, your doctor will probably tell you to stop taking both vitamin D and calcium supplements.
