Vitamin D is essential for the health of the human body. This important compound helps grow and maintain bones and teeth, the immune system, brain health, and regulate inflammation.
As we age, our muscles and bones tend to weaken, and vitamin D can play a vital role in muscle and bone development. Some studies have found that not getting enough vitamin D can increase age-related muscle loss and the risk of falls. So, does this mean that taking vitamin D supplements can slow down aging?
A new review by Italian researchers has highlighted an important aspect of this association.

For decades, doctors have recommended vitamin D supplements for people with osteoporosis and to prevent bone fractures, because vitamin D deficiency is associated with symptoms of osteoporosis.
It’s worth noting that although vitamin D is found in certain foods, it can be difficult to get enough vitamin D if you don’t get enough through diet alone or if you don’t get enough sunlight. To do.
However, recent research suggests that vitamin D supplements do not necessarily help prevent age-related bone loss and fractures in healthy people.
In a recent review, Ruggiero et al. summarized observational studies and clinical trials examining the potential effects of vitamin D on the biological hallmarks of aging and found a lack of evidence. [animal] model. ”
On the other hand, some research suggests that vitamin D may slow epigenetic aging, as people with low levels of vitamin D are biologically older than those with sufficient levels.
The authors point out that vitamin D supplementation may also help reduce DNA damage, saying, “While some studies support a protective role of vitamin D on telomerase activity in obese people, telomere length It doesn’t seem to be having an impact,” he added.
Also, because there are so few human studies, there is little evidence about what doses and at what ages vitamin D supplements are effective, and results are mixed.
Some studies suggest that taking certain doses of vitamin D is safe for the average person, but it varies from person to person. Research shows that taking large amounts of vitamin D can be harmful. It’s also important to stress that vitamin D supplements can interact with prescription medications such as cholesterol-lowering statins.
Experts also claim that taking more vitamins in supplement form is not necessarily better for your health. They say it’s important to prioritize activities you can do to improve your health and live longer, such as eating a balanced diet and getting outdoors.
“Despite the interest in vitamin D supplementation as a strategy to support human longevity and some evidence about vitamin D’s potential to modulate the hallmarks of aging, we have not reached the bench-to-bed tipping point. “We are still a long way off,” Ruggiero and colleagues concluded.
The results of the review were published in Nutrients magazine.
