fiveITAMIN D has returned to the news after a new study found that daily supplements could slow the age -related damage to DNA. The useful defense of our genes for the devastation of time remains when the average life expectancy is widened. Needless to say, this is the latest of the long estimated health benefits to vitamin D supplements, and most of them did not meet the initial over -advertising.
Time to declare my interest: Despite skepticism, vitamin D is the only supplement I take. To be honest, I know that if I need a) and b) it’s good for me, I know that a low -level vitamin is associated. As the risk of health problems increases, from rickets and osteoporosis, stroke, heart attack, cancer and diabetes. In addition, most people in the UK should take supplements according to long instructions.
Although it is best known as the action of bones, vitamin D receptors are found in cells throughout the body, including the immune system, so it is much more important than a healthy skeleton. Foods such as oily fish, eggs, and artificially enhanced powdered milk can supply some of their everyday requirements, but most of them come from the internal production of the skin led by the action of sunlight. Therefore, it is the nickname “Sunlight Vitamin”. In the UK, however, the sun is not powerful enough to supply fuel to the process and level in the dark winter throughout the year. And to the north, the more you live in England, the greater the problem.
• Vitamin D supplements can respond to aging, according to a study, according to a study
If the skin is dark, everyone is covering a high SPF ray screen to complicated or protect yourself. Therefore, it is not surprising that deficiency is common. Although the estimates are diverse, according to the guidelines of the National Health and Health Institute of Health and Health, about 23 %of the 19-64 years of 19-64 years of age, there is a vitamin D deficiency (25 nmol/L) with vitamin D deficiency (less than 25 nmol/L) between January and March.
Thus, the guidelines that have been established for a long time but are ignored are advocated to take supplements (generally 10mcg or 400 IU) for the rest of the groups of other groups, such as children, pregnant women, children who are not many or dark skin, from October to March. Are you following this guideline but are doing good things?
The low level of vitamin D is associated with the increase in the risk of various diseases does not mean that supplements protect supplements. Many tests have concluded that taking extra vitamin D is generally an agreement that the risk of a heart attack or stroke or cancer development, multiple sclerosis, or type 1 diabetes does not significantly reduce the risk of immunity.
Covid is an example of this obvious paradox. According to a study during the epidemic period, people with low vitamin D are likely to cause serious chest complications, but it is still not clear whether the supplement improves the results (some studies are not).
• More expert advice on healthy life, fitness and well -being
There are many reasons why many studies on the protection effect of vitamin D were crucial or disappointing. Low -level vitamins can be a poorly healthy marker. In some high -risk groups, such as obesity, there is a lower tendency, and in groups with some types of kidney and liver disease, no supplements are changed. There is also a controversy over constructing a healthy level with a large gray area between the recognized deficiency and the normal readings. And many studies include people with a variety of vitamins (some normal).
Part of the problem is that supplements can help prevent long -term diseases at the bottom of the spectrum, but most of them may be almost or nothing at the top. We know that they work well in extreme cases such as rickets (where bones are soft due to vitamin D deficiency), but this is not automatically translated into stronger skeletal for the rest of our people. Or vitamin D researcher once told me, “Putting more gasoline in the car can’t show better performance, but I don’t want to make a mark, but I don’t want to fall.”
I am clear. Vitamin D deficiency is best to avoid and is common. So in the dark moon, we will continue to take supplements (20 mcg/800 IU per day). They are safe with cheap and wise doses. And I advise you to do the same.
Do not test or test
• NHS laboratories in the area use the following reference range for vitamin D blood test. 50 nmol/l = appropriate, 25-50nmol/l = 25 nmol/l = serious deficiency.
• Advice NICs for everyday tests of vitamin D unless someone suspects or confirms or confirms chronic extensive pain that someone can not explain or other bone diseases or other bone diseases.
• It is better to take supplements rather than test people with high risk of deficiency due to lifestyle or fundamental medical condition.
• If you still want to know the level, you can use the DIY home test. Boots sell one for £ 7.99.
• Recent studies have shown that weak sunscreen (less than SPF15) does not interfere with vitamin D production in most users (surprisingly no sun exposure is required to meet demand). A higher SPF is another reason to consider supplements.
