Scientists have discussed the best ways to delay our cells. According to a new result of a large -scale survey, vitamin D supplements can give hands not to damage the cells.
This discovery comes from a wide range of research projects related to the elderly in the United States. It is characterized by Dr. Joann Manson, the best expert. Mass General BrighamMajor research institutes were recognized as dedication to patient treatment and scientific investigation.
What is telomeres and why it is important
Telomer It is the end of the nature protection of the chromosome. They are generally shortened during normal aging and can contribute to later conditions.
Some researchers think that telomeres work like a small counter in cells. If this counter is too short, you can set the stages of various medical problems.
Vitamin D and cell aging
In order to study the effects of vitamin D, the team recruited women over 50 years old, men over 55 and 55 years old. They allowed individuals to take 2,000 IU vitamin D3 or inactive capsules for five years, and tested separate omega -3 supplements in the related arms of the study.
They examined the length of telomeres at the start of the exam, and then reviewed them in the second and fourth grade. All measurements have been collected in a way of relying on certain laboratory technology. Quantitative PCRAnalyze the DNA sample correctly.
Vitamin D has helped to slow down telomeres.
“VITAN is the first large and long -term random test that shows that vitamin D supplements protect telomeres and preserve telomeres, and scientists have reported that vitamin D supplements helped maintain telomeres during the study period.
They found that an individual taking vitamin D has experienced a smaller decrease in telomeres than the group is not taking. According to their reports, this difference can be the same as for almost three years in cell aging.
Omega -3 supplements did not protect cells
Omega -3 fatty acid Since we have been promoted to heart and brain health for a long time, researchers were wondering if it could help to slow cell aging. But in this study, the omega -3 supplement did not make a big difference.
Participants who took 1 grams of marine -based omega -3s daily have no significant change in telomeres than placebo. This suggests that Omega -30,000 may not affect this specific aging process that is less than four years old.
Vitamin D is related to low inflammation
past research Vitamin D suggests that the marker of inflammation can be reduced in a particular population. Reduction of inflammation is associated with a positive impact on the condition associated with aging.
“According to our research, the vitamin D supplementation of the target may be a promising strategy against the biological aging process, but further research is required, but Haidong Zhu, the first author and molecular geneticist of Georgia Medical University, said. Ogger Star University.
Vitamin D can support cell health.
Experts warn that this evidence does not guarantee that vitamin D will spare no individuals in all aging diseases. However, the result is a potential advantage that supports the cell health of some adults who may not be able to get enough nutrients in everyday life.
This study emphasizes the concept that regular intake of vitamin D supplements can preserve part of our cell protection. Scientists hope that future work will be able to clarify the best doses and those standing for the most.
Is vitamin D enough?
The dose used in the study (2,000 IU vitamin D3 daily) is higher than the typical recommended daily intake for adults in the United States, which is from 600 to 800 IU depending on age. But according to the National Institute of Health, the research capacity is still considered safe for most healthy adults. guideline.
In other words, no one needs additional supplements. People who eat regular sunlight exposure or eat vitamin D -rich foods such as fat fish, egg yolks or reinforced dairy products may already be obtained. It is recommended to consult a doctor before starting a high dose supplement.
Next step
The team in this project requires more tests in other groups. They want to see if these results are maintained by young people or existing diseases.
Efforts are being made to investigate factors such as genetic configuration and lifestyle selection. These details can show why vitamin D is not for others and other vitamins that go well with strategies.
