vitamin D Supplements can help protect the slow cap on our chromosomes AgeingSparking hopes that sunlight can keep us healthy for a long time, A recent study Gives suggestions.
Researchers found that 2,000 IU (international units, a standard measure) Vitamin) Of vitamin D The daily helped to maintain the telomer – small structures that act like a plastic hat on the shoe lace protect us DNA From Loss Every time Cells split.
Telomere Each of our 46 chromosomes sits at the end of each time when a cell makes a copy of itself, it becomes small. When they become very small, Cells Can no longer divide and eventually die.
Scientists have linked small telomers with some of our most dangerous diseases. AgeingInvolved cancer, Heart disease And Osteoarthritis,
SmokingLong -term Tension And Depression It seems that all are increasing the speed of shortening the telomere Inflammatory processes They also affect the body.
Beyond strong bones
It is well known for whom Vitamin D is required for bone healthHelps our body absorb calcium. People, teenagers and dark colored skin or sunlight require especially adequate levels Strong bones manufacture and maintenance,
But Vitamin D also gives us strength Immune systemA review of evidence found that vitamin D supplements can reduce respiratory infections, especially in people who have vitamin D deficiency.
Quick Research It has even suggested that it may help prevent autoimmune diseases Rheumatoid arthritis, A type of tree And multiple sclerosisHowever, more tests are required.

since Inflammation causes damage to telomerAnti -inflammatory effects of vitamin D can explain its protective role.
In this recent study of Augusta University in the US, researchers monitored 1,031 people with an average age of 65 for five years, initially, two years later and four years later, measured their Telomer. Half of the people took 2,000 IU vitamin D per day, while the other half got placebo.
The results showed that telomeres were preserved by a 140 base pairs in the vitamin D group compared to the placebo. To keep it in reference, previous research It was found that telomeres become small in a decade naturally about 460 base pairs become smaller, showing that the protective effect of vitamin D can be really meaningful.
This is not the first promising discovery. previous study Equal benefits are reported, whereas Mediterranean diet – rich in Anti -inflammatory nutrient – It has also been connected to long telomeres.
Hunt
But there are some important points to note. Some researchers warn it Extremely long telomeres Can actually grow Risk of diseaseSuggesting that there is a sweet place that we have not yet understood.
There is no consensus on the correct dosage. Augusta researchers used 2,000 IU per day – much more than current recommended intake 600 IU 800 IU for those under 70 and older adults. Still other research suggests 400 IU Winter can help protect.
Experts say Optimal dose Probably depends on individual factors, in which the existing vitamin D level, overall nutrition and how vitamin contacts other nutrients.
Although these conclusions are exciting, it is too early to start taking high doses of vitamin D in the hope of slowing down aging speed. The strongest evidence of healthy aging still indicates the basics: balanced diet, regular exercise, quality sleep, not smoking and stress management, all naturally support telomere health.
However, if you are deficient in vitamin D or there is a risk of poor health of bones, the supplement supported by decades research is a sensible option. As scientists are solving the mysteries of aging, the role of vitamin D in keeping our cellular watches running can prove to be just one piece of a very large puzzle.
