Explanation:
A provitamin is a substance that the body can transform into an active vitamin through metabolic processes. If compared with vitamins, provitamins have no biological activity or are much lower. In other words, provitamins are vitamin precursors.

Running Is a very important physical activity. It is needed in everyday life, and it should be practiced to keep your body healthy. Younger children should run a lot, that's why sports are so encouraged in school.
Running can significantly improve physical and mental health. As a form of aerobic exercise, running can reduce stress, improve heart health, and even help alleviate symptoms of depression. Some researchers think running may be so good for us because it's something we evolved to do.
