Vitamin D – The Amazing “Sunshine” Vitamin….

We need vitamin D for strong bones.

Vitamin D is a steroid vitamin, a group of fat-soluble prohormones, which encourages the absorption and metabolism of calcium and phosphorous.

Five forms of vitamin D have been discovered, vitamin D1, D2, D3, D4, D5. The two forms that seem to matter to humans the most are vitamins D2 (ergocalciferol) and D3 (cholecalciferol).

Vitamin D is available in supplements in two forms: D2 and D3.

D2 is not equal to D3.

Studies suggest that D3 can be up to three times more effective in raising the vitamin D level quickly and staying longer.

Vitamin D allows your body to absorb calcium. Without it, your bones can become brittle and weak.

Low blood levels of vitamin D may have effects heart problems and a greater risk of depression.

Researchers have found more severe asthma when vitamin D levels are low.

Your body produces it on its own. The trick is exposing some portion of your skin to direct sunlight for 15 to 30 minutes a few days a week. But the UV rays that stimulate production of vitamin D can also cause skin cancer. So most experts don’t recommend getting your vitamin D from sun exposure. The darker a person’s skin, the more difficult it is to get vitamin D from sunlight.

Studies suggest that vitamin D may even offer protection against developing breast cancer.

Vitamin D and Depression isn’t clear how they are related. But studies have linked low levels of vitamin D to depression among older men and women.

One way to get vitamin D is through your diet. Nearly all milk is fortified with vitamin D, and many brands of orange juice are, too. Even ready-to-eat breakfast cereals can contain a healthy dose. So just by making sure you eat breakfast, you can make every day a ” vitamin D day.”

How much vitamin D you need depends on your age and risk factors.

Children may be able to get the vitamin D they need for growing bones through foods, including those fortified with vitamin D, such as milk.

Testing for Vitamin D your doctor can order to check your level of vitamin D. There is a simple blood test. keep your bones healthy when your blood level is 20 nanograms per millilitre (ng/mL) or higher.

There is an upper limit to how much vitamin D you can safely take. The Institute of Medicine recommendations for adults say that a daily intake of up to 4,000 IU of vitamin D is safe. The best approach is to check with your health care provider before taking vitamin D supplements.
