In medicine it has occurred quite a few times in recent years that a medicine, or a line of research which seems to show great results from a particular medicine, in this case a vitamin (Vitamin D) which is in reality a hormone, rises in popularity only to fall out of favor soon after, when more results from research then come in.
Vitamin D is another such case. It all sounded so promising, with large numbers of people starting to take this vitamin as a general health supplement. So, it comes as a surprising revelation by the US Institute of Medicine in the past few days, that the results of further research now show that to be largely erroneous.
Over the last few years there have been a succession of studies which have supported the idea that everyone would benefit from taking additional vitamin D into their bodies , and many researchers have suggested the use of supplements would be beneficial.
The idea has seemed very plausible. Vitamin D is produced within our bodies naturally when we are exposed to sunlight. Small quantities are present in certain foods as well, such as in fish and where added to breakfast cereals.
However, in northern climates in winter when there is little sunlight or we don’t go outside much during the day our body’s reserves become depleted. So, it seemed logical to expect that supplementing vitamin D levels would be helpful to our bodies.
Not so, says this large and influential study and the large doses suggested beneficial by a number of researchers (above 400 units a day) may be harmful.
There will be those involved in the sales of vitamin D tablets and medicines who may wish that this was not the case, because Vitamin D sales which have been rising fast, are now likely to drop below their value which in 2008 to 2009 amounted to about $430M.
Vitamin D is a term used to name one or two kinds of related compounds. All are fat-soluble and act to manage calcium metabolism. If you are thinking about Vitamin D reinforcement, it is vital you get the dose that is right for your age, and doesn’t surpass new lower IoM maximum measures.
Vitamin D is a fat-soluble vitamin, meaning it becomes stored in the body, so in extreme cases huge doses could build up to perilous levels. Vitamin D deficiency can cause weakness and slowness, both elements of frailty. Vitamin D deficiency “may account for a couple of thousand early deaths from colon, breast, ovarian and other cancers annually,” they wrote in the North American Book of Public Health.
Vitamin D helps make sure that the body absorbs and keeps calcium and phosphorus, both urgent for building bone. Lab studies indicate that vitamin D can play a critical role in controlling illnesses. Vitamin D is also concerned in controlling the immunological reaction and cells, where it may help in warding off cancer.
Vitamin D deficiency can cause weakness and slowness, both elements of frailty. Some health professionals have advised vitamin D additions for older adults whose blood levels of vitamin D are below thirty nanograms per milliliter ( ng / ml ), the analysts expounded. Deficiency in this vitamin can also lead to rickets in babies, causing bowed legs and knocked knees. In adults, deficiency can cause bone weakness and increased chance of fracture.
