Because vitamin D helps your body absorb calcium, it plays a role in your bone health. Studies involving older adults have associated low vitamin D levels with an increased risk of falls and fractures. Another finding shows that at age 50, your kidneys may become less effective at metabolizing inactive vitamin D into its active form.

At age 70 and beyond, your body will produce about one-third less vitamin D through sun exposure than it did when you were 21. Plus melanin, which determines your skin pigmentation and protects your body from harmful ultraviolet radiation (UV),can also impair your skin’s ability to produce enough vitamin D from sunlight. Darker-skinned individuals may need up to 10 times more sun exposure to produce adequate vitamin D levels as compared to a person with lighter skin. Who knew?

Another good thing about getting adequate sun exposure is that your mood automatically elevates when you are in the sun, thanks to the brain hormone serotonin. Researchers examining the effects of vitamin D on the moods of 80 elderly patients found the ones with the lowest vitamin D levels were 11 times more likely to suffer from depression. So sunning daily and taking a vitamin D supplement can help ward off depression.

If you are obese, some experts recommend you increase your intake of vitamin D. Why? Because vitamin D is fat-soluble, when your fat cells uptake it, less is available for use elsewhere in your body.

Here is a list of vitamin D deficiency symptoms that most people ignore from Healthyway.com.

The optimal vitamin D level for general health ranges between 40 to 60 nanograms per milliliter (ng/ml). The ideal way to raise your vitamin D is by regularly and sensibly exposing large amounts of your skin, such as your arms, back, chest and legs, to sunshine. Getting outdoors at or around solar noon is the best time to soak up the sun. If for whatever reason you cannot get outdoors, or not frequently enough to receive sufficient UV exposure, consider taking an oral vitamin D3 supplement along with vitamin K2 and magnesium.
