Some doctors might suggest taking a supplement, but guess what they suggest taking? a cheap once a day multivitamin. There are some good supplements that can benefit people, but mostly older people: https://www.medicalnewstoday.com/art...ntial-benefits Some people have iron deficiencies need to take iron pills, but only under doctors care because you can OD on iron; certain older people need vitamin B12, but again a doctor will test to see if you are deficient in that area.
