How does Vitamin D help our body


If you’re like many people, you may find yourself getting the blues from time to time – and even more often during winter months. When this happens, the culprit may be a deficiency in vitamin D.

Why?


The body generates vitamin D on its own, when skin is exposed to sunlight. But with shorter days and less time spent outside in colder seasons, you may not produce enough of this essential vitamin, which helps regulate your moods, immune system and neuromuscular system, while also aiding in calcium absorption. It also plays major role in the life cycle of human cells.
Vitamin D is so important that your body makes it by itself -- but only after skin exposure to sufficient sunlight. This is a problem for people in northern climates. In the U.S., only people who live south of a line drawn from Los Angeles to Columbia, S.C., get enough sunlight for vitamin D production throughout the year.
Dark skin absorbs less sunlight, so people with dark skin do not get as much vitamin D from sun exposure as do light-skinned people. This is a particular problem for African-Americans in the northern U.S.

What Vitamin D Does for You


  • Helps the body absorb calcium for strong bones and teeth
  • Required for healthy cells and a healthy heart
  • Supports teeth, breast, colon, and immune system health

Results of Vitamin D Deficiency


Common symptoms of low vitamin D can be subtle: ongoing fatigue, periodic depression (sometimes accompanied by “brain fog”), and muscle weakness. But left unchecked, a real D deficiency can lead to more severe health problems, like osteoporosis. You may be at greater risk if you’re age 65 or older, or if you eat a vegan diet, suffer from kidney problems, or have dark skin.

What You Can Do


As with many health issues, a balanced diet can help minimize your risks. Foods like fish (especially salmon), eggs, cheese, and fortified milk offer natural forms of vitamin D. You can also consider adding a vitamin D supplement into your nutritional routine. With more vitamin D in your system, you may find relief from those winter blues, and gain more energy in the process.

How Much is Enough?


Many health experts are now recommending an increase to the Recommended Dietary Allowance for vitamin D, suggesting that you get a minimum of 2,000 International Units (IU) each day.
Talk to your doctor if you’re unsure just how much vitamin D is best for you.
