اشکالات گرامری متن زیر رو میشه بگید

صحیح:
 "We may not be able to get all the vitamins our bodies need from food, so it is better to take a daily multivitamin with a doctor's prescription."

Missing article: The phrase "our bodies need" is missing an article. It should be "our bodies' need" to indicate possession.

Subject-verb agreement: The subject of the sentence is "it," which is singular. Therefore, the verb should also be singular. The correct verb form is "is," not "are."
