A vitamin has been found that can prolong life

According to scientists, human lifespan is the result of a complex interaction between genetics and the influence of the environment. Although life expectancy has increased over the past two centuries, scientific knowledge about the factors that influence longevity is still insufficient. Researchers are sure that the environment plays a key role in the aging process.

It has been proven that oxidative stress has a negative effect on longevity. Antioxidants can mitigate the effects of free radicals on the body. For example, a new study showed that a higher concentration of vitamin A is associated with a longer life.

In a scientific paper, scientists looked at a number of different antioxidants (ascorbate, lycopene, selenium, beta-carotene, retinol) and metabolites (ascorbate, alpha-tocopherol, gamma-tocopherol and retinol), comparing their presence in the body with information about the life expectancy of the participants.

As a result, the researchers did not find any connection between vitamins C, E and other factors and life expectancy, but they found that the higher the concentration of vitamin a over a longer period of time, the more likely people were to live longer. “Long-term increased exposure to the retinol metabolite is causally related to the life expectancy of the population as a whole,” the scientists said.

The experts noted that the obtained results can be confirmed by future studies using additional genetic factors and data from large-scale GWASs ( genome-wide association search).
