Vitamin D is pivotal to the absorption of calcium and maximizing bone health. Women suffer great morbidity and mortality related to osteoporosis and fractures, which may be decreased by interventions such as vitamin D. In addition, extraskeletal benefits of vitamin D have been postulated including positive effects on cancer.

Both the classical and nonclassical functions of vitamin D will be discussed here, with a focus on women. Although vitamin D deficiency is currently a hot topic of discussion, the debate started long ago. Initially identified as a vitamin in the s, scientists now define it as a prohormone.

By , food and drinks were being fortified, but it was not well monitored, and children experienced toxicity, causing many countries to stop fortification. From the liver, the 25 OH D travels to the kidneys where it is converted into 1,dihydroxyvitamin D 1,25[OH] 2 D or calcitriol , which is the active form of vitamin D. Many factors contribute to vitamin D deficiency.

Finally, diseases of the kidneys and liver affect vitamin D levels by disrupting synthesis. Annually, there are 1. Vitamin D is known to affect bone physiology with its impact on calcium and phosphorus levels. Studies have been done evaluating the effect of vitamin D on fractures, falls, and muscle strength. The results showed no statistically significant reduction in hip fractures or total fractures. In addition to risk of fractures, correlation between vitamin D and falls has been investigated.

One downside of this study is the smaller sample size. Although the above results can be difficult to interpret, it is important to note that the benefits or harms of vitamin D supplementation may be dose related and need to be studied separately from calcium.

Further large randomized controlled trials are needed to shed light on the inconsistent results. In addition to the classical musculoskeletal functions, vitamin D has been found to possibly exert influence on nonclassical sites, 1 such as the brain, prostate, breast, and colon. A possible issue with this trial was that follow-up was 7 years, but the latency for developing colon cancer is 10 to 20 years.

Garland et al looked at 30 studies with vitamin D and colon cancer, finding 20 with a statistically significant benefit of vitamin D, its metabolites, or sunlight exposure; 5 with borderline statistically significant benefit; and 5 with no association. Vitamin D has also been a point of discussion in reproductive and endocrine fields. There have been cross-sectional studies showing a possible association between low vitamin D and menstrual dysfunction, infertility, hirsutism, obesity, and insulin resistance in patients with PCOS.

However, there is a paucity of evidence proving causality; thus, further research is needed. They do not feel there is sufficient evidence for screening all pregnant women, but, if a deficiency is identified, most experts agree that to IU per day is safe. To get vitamin D from sunlight, exposing arms and legs for 5 to 30 minutes between the hours of 10 am and 3 pm is usually sufficient but depends on skin pigmentation, time of day, latitude, and season.

Being a fat-soluble vitamin, vitamin D toxicity is a concern, but fortunately it is an extremely rare occurrence. Researchers and clinicians over the years have shown that too little and too much vitamin D can have negative health consequences.

Unfortunately, we still do not have clear insight as to exactly how much vitamin D is best. Confounders such as skin pigmentation, latitude of residence, obesity, and others make standardizing and simplifying the recommendations difficult.

Further randomized controlled trials are needed with a large diverse population supplementing with vitamin D alone. Specifically for women, further research is needed for osteoporosis and fracture prevention, cancer incidence, pregnancy outcomes, and PCOS treatment. Factors that may impact vitamin D absorption and availability such as gastrointestinal issues and body mass index need to be adjusted for in the studies.

For now, clinicians should take into consideration individual variables when recommending vitamin D supplementation. Author Contributions. Conceived the concept: TB, MG. Analyzed the data: TB, MG. Wrote the first draft of the manuscript: TB. Contributed to the writing of the manuscript: TB, MG.

Taking too much vitamin D can cloud its benefits and create health risks

Diane E. With conflicting nutritional information available from multiple sources, it's hard to decide not only what to eat, but what, if any, supplements to take. It's commonly recommended that women — especially as they get older — should take calcium and vitamin D supplements to help strengthen bones and protect against future fractures broken bones. However, the U. Preventive Services Task Force USPSTF recently concluded that there isn't enough proof that taking these supplements before or after menopause prevents fractures in women who never had fractures before, and that the possible harm supplements may cause is unknown.

You can also get it through certain foods and supplements to ensure adequate levels of the vitamin in your blood. Vitamin D has several important functions. Perhaps the most vital are regulating the absorption of calcium and phosphorus , and facilitating normal immune system function.

Vitamin D is necessary for building and maintaining healthy bones. That's because calcium, the primary component of bone, can only be absorbed by your body when vitamin D is present. Your body makes vitamin D when direct sunlight converts a chemical in your skin into an active form of the vitamin calciferol. Vitamin D isn't found in many foods, but you can get it from fortified milk, fortified cereal, and fatty fish such as salmon, mackerel and sardines. The amount of vitamin D your skin makes depends on many factors, including the time of day, season, latitude and your skin pigmentation.

A report from the Institute of Medicine setting new guidelines for vitamin D and calcium increases the recommended levels of D, but maintains or decreases the recommended levels for calcium. Most Americans and Canadians, the report states, are getting enough vitamin D and calcium, although older men and women may fall short. Women, beginning at age 51, and both men and women over age 71, need 1, mg of calcium a day, the same as in The report also notes that taking more than 4, IU of vitamin D daily up from 2, IU or 2, mg of calcium daily down from 2, mg increases the risk for harm. Very high levels of vitamin D above 10, IU a day may cause kidney and tissue damage. Evidence of risks at lower levels is limited, but some studies offer tentative signals about adverse health effects.

Recent media reports and studies have left many confused about calcium supplements and their effect on the heart. While some studies have suggested a possible link between calcium supplements and heart-related problems, substantial evidence supports that taking the recommended amount of calcium supplements poses no risk to the heart. What we know is that experts agree getting enough calcium is critical for bone health and overall health. NOF recommends that women age 50 and younger get 1, mg of calcium from all sources daily and that women age 51 and older get 1, mg. For men, NOF recommends 1, mg of calcium daily for those age 70 and younger and 1, mg for men age 71 and older.

In this article, the author looks at complications and issues caused by vitamin D deficiency in women. Interest in vitamin D has been growing over the past 10 years, and is often seen by some as a necessary nutritional supplement to the diet. Vitamin D is the collective term for a small number of fat-soluble steroid hormones needed for the intestinal absorption of calcium, magnesium and phosphates, and without which blood levels of these chemicals will fall. The expression of the vitamin D receptor on many tissues points to a broad role in physiology, and therefore, potentially, in pathology. Nevertheless, interest in vitamin D follows from its role in maintaining healthy bone, as low levels of calcium, possibly driven by lack of vitamin D, leads to weakness.

One component of bone strength is measured as bone mineral density, or BMD: the amount of mineral content in an area of bone. Bones might seem static or unchanging, but they are living tissue that is constantly rebuilding itself through an ongoing process of repair and maintenance.
