Vitamin D3 is one of the most important nutrients that will help improve the overall health and well-being of a person. Vitamin D3 or cholecalciferol is quite unique due to the fact that it is derived from 7-dehydrocholesterol. This vitamin is converted to 1,25-dihydroxy and Calcitriol by the liver and kidneys of an individual.
Calcitriol acts like a hormone in controlling calcium, bone metabolism, phosphorus, and neuromuscular function. D3 is considered the only vitamin that your body can manufacture from direct sunlight. But, because most people live indoors and use sunscreens extensively due to fears of skin cancer, they lose the opportunity of utilizing the life-sustaining, immune modulating and bone-building benefits of vitamin D3. This article provides a comprehensive overview of the most important benefits of vitamin D3.
Connection between vitamin D3 and bone health
The connection between vitamin D3 and bone health has been known for centuries. There is more than enough research to show Calcitriolâ€™s role in reducing the risk of fractures to a significant degree. But the latest research on this important vitamin reveals that lack of D3 is linked to a host of other health conditions such as cancer, back pain, insulin resistance, pre-eclampsia during pregnancy, macular degeneration, depression, and impaired immunity.
Today, it is crystal clear that vitamin D3 plays a much more important role in the overall health and well-being of an individual. It is also becoming clear that a large percentage of people are deficient in this important nutrient. In fact, the fear of getting skin cancer has stopped many individuals from obtaining a beneficial amount of sunlight. Your skin will use the energy of sunlight in order to produce vitamin D3 from 7-dehydrocholesterol.
Even people who go out in the sun often use some kind of sunscreen. These people are also deficient in this important nutrient. When a person ages, his or her skin is less equipped to produce this important vitamin. There was one study conducted about age-related declines in kidney functions. It was concluded that such declines can be reversed with the right amount of vitamin D3 to these people.
High Dosages Of Vitamin D3
The American Journal of Clinical Nutrition published a report sometime back. In this report, prominent researchers from leading research institutions such as the University of Toronto, University Hospital in Zurich, Tufts University and Brigham Women™s Hospital lashed out at the world media for its inaccurate reporting of vitamin D3 supplementation. The traditionally recommended dosage is 200 IU/day from birth to 50-years of age. It becomes 400 IU/day from 51-70-years and 600 IU/day there onward. Researchers point out that these dosages are not enough according to the latest findings in this department.
Researchers point out that the public will be better served by a higher daily dosage of vitamin D3. They suggest simple low-cost changes such as increasing the vitamin D3 fortification in vitamin D3 supplements and consuming more foods with vitamin D3.
Another challenge is the outdated acceptable upper limit for D3 consumption. It is currently set to 2,000 IU, but the latest research shows that 10,000 IU is a much safer upper limit for vitamin D3. The research on this matter is still not concluded.
There are so many studies to show that vitamin D3 affects individuals in a much bigger way than the medical community believes. Not taking enough of this important vitamin will leave you vulnerable to so many negative health conditions. Here are some of the conditions that may affect a person who doesn’t get enough vitamin D3
Deficiency of Vitamin D3
Older adults with deficiency of vitamin D3 undergo psychiatric and neurologic disorders and depression as a result of it. There was a study conducted on 80 older adults. The deficiency of Vitamin D3 was associated with a low mood and with impairment of cognitive performance. There is a number of studies which link musculoskeletal disorders with the deficiency of vitamin D3. The newest study shows that deficiency of vitamin D3 can develop chronic lower back pain in women.
There were 60 female patients in Egypt who were complaining of lower back pain. The back pain lasted for more than three months in most of these women. Researchers measured the vitamin D3 levels in these women. The study showed that these women had considerably low levels of vitamin D3 compared to healthy women of the same age. Vitamin D3’s ability to improve bone and musculoskeletal system health is known for centuries. Deficiency of vitamin D3 can cause osteopenia, osteoporosis, and osteomalacia, which is a painful bone disease. It can also cause muscle weakness, and increase the risk of falls and fractures. The deficiency can also alter the regulatory functions of the parathyroid hormone (PTH). This may result in hyperparathyroidism, which will increase the patient’s risk in fractures and osteoporosis.
The latest scientific studies have shown that vitamin D3 can improve the cognition faculties of an individual. They conducted a study and the results were quite astonishing. People who were suffering from low vitamin D3 levels scored worse on mental function tests compared to people who were having healthy levels of vitamin D3 levels in their body. The nutrient is capable of improving cognitive functions even in older adults. So many other health conditions are linked to a deficiency of vitamin D3 in people.
Some of these health conditions include multiple sclerosis, high blood pressure, diabetes, fibromyalgia, insulin resistance during pregnancy, an increased risk of pre-eclampsia and rheumatoid arthritis. The latest studies show that deficiency in vitamin D3 is linked to an increased risk of early age-related macular degeneration. This is why it is important that you take the required levels of vitamin D3 on a daily basis.
Patients can check their vitamin D3 levels by getting their physician to check the serum 1,25-dihydroxy D3 levels. This may determine the proper levels of supplementation required for each individual. Testing is essential since, in a small number of patients, vitamin D3 supplements may raise their levels of calcium. This is more prevalent with the African-American population in the country. All in all, vitamin D3 is one of the most important nutrients for your overall health and well-being in the long run.
