Low Vitamin D Symptoms and What You Can Do About It

If you have watched any doctors on TV lately, you may have heard a lot about the extreme importance of having good levels of Vitamin D in your system. Low Vitamin D can cause an array of debilitating symptoms that can make a person think they are doing crazy or worse yet, slowly dying.

I have experienced low Vitamin D levels myself, and spent years trying to figure it out. I am on my way to rebuilding, but it can take many weeks or even months to get back on track.

This lens will talk about the symptoms of Low Vitamin D as well as how you can increase your levels and get on the road to health again.

What is Vitamin D and What Does It Do?

Vitamin D is available in many dietary sources such as eggs, fish, fortified milk, and cod liver oil. The sun gives us a significant amount of our dailt Vitamin D intake. As few as 10-15 minutes of exposure is believed to be enough to prevent deficiencies. There are several different forms of Vitamin D. There are two particular forms that are important for human beings: ergocalciferol (vitamin D2) and cholecalciferol (vitamin D3). Vitamin D2 is synthesized by plants. Vitamin D3 is synthesized by humans in the skin when it is exposed to ultraviolet-B rays from sunlight. Foods can be fortified with vitamin D2 or D3.

The major function of Vitamin D is to maintain normal blood levels of calcium and phosphorus. Vitamin D also helps in the absorption of calcium, which helps to form and maintain strong bones. Recent research indicates that Vitamin D may provide protection from osteoporosis, hypertension (high blood pressure), cancer, and several autoimmune diseases.

Rickets and osteomalacia are classic vitamin D deficiency diseases. Groups who may be at a high risk for vitamin D deficiencies include the elderly, obese individuals, exclusively breastfed infants, and those who have limited sun exposure. Also those who have inflammatory bowel disease may be at greater risk.

After following more than 5,000 people for 5 years, the researchers found those with lower than average vitamin D levels had a 57 percent increased risk of developing type 2 diabetes compared to people with levels in the recommended range.

“Studies like ours have suggested that blood levels of vitamin D higher than what is recommended for bone health may be necessary to reduce the risk of developing type 2 diabetes,” said lead author Dr. Claudia Gagnon, a fellow at the Western Hospital at the University of Melbourne in Australia when the study was done.

Vitamin D is manufactured by the body in response to sunlight and also occurs naturally in some foods, like eggs, cod and salmon. The vitamin is best known for its role in working with calcium to build bones.

The Institute of Medicine recommends that adults get about 600 IU of vitamin D a day to maintain circulating levels in the desirable range.

Past studies have shown that vitamin D may also help keep blood sugar levels under control (see Reuters Health story of February 23, 2011).

In type 2 diabetes, the most common form of the disease, the body can’t use insulin it produces efficiently to control blood sugar levels. Vitamin D may play a role by increasing the release of insulin, Gagnon said.

To see whether circulating D levels and calcium consumption influenced insulin sensitivity and diabetes risk, Gagnon’s team measured the vitamin D blood levels of 5,200 people without diabetes. After 5 years, about 200 of them had developed diabetes, and the researchers measured everyone’s vitamin D levels again.

The researchers found that twice as many people (6 in 100) with low blood levels of vitamin D later developed diabetes, compared to those with blood levels in the normal range (3 in 100).

When the researchers took into consideration risk factors for diabetes such as age, waist circumference, and a family history of the disease, the increased risk from low D levels translated to 57 percent, relative to those with higher levels.

Calcium is also thought to participate in insulin release, but the researchers found no link between the mineral and risk of developing diabetes later.

“Lower levels of vitamin D in the blood were associated with an increased risk of developing type 2 diabetes,” Gagnon told Reuters Health by e-mail. “However, our findings do not prove cause and effect.”

Further studies are needed, Gagnon’s group writes in the journal Diabetes Care, both to directly test whether vitamin D supplements make a difference in diabetes risk, and if so, to determine the optimal circulating D levels to minimize that risk.

It’s hard to know what exactly the link between vitamin D and diabetes is, Dr. Ian de Boer, assistant professor of medicine at the University of Washington in Seattle, told Reuters Health.

But obesity and inactivity, the highest risk factors for type 2 diabetes, may be the cause of low vitamin D levels, said de Boer, who did not work on the Australian study.

Vitamin D has also been linked to lower risks of asthma, heart disease, and certain cancers. However, there hasn’t been much evidence showing that taking supplements helps these conditions.
