I say 30s but to be real, the earlier in adulthood you start taking these supplements, the better. Keep in mind that a varied and balanced diet consisting primarily of whole foods is usually good enough to give you the vitamins, minerals etc. that you need. For those of us who find it harder to be perfect in our consumption habits however, and those who have chosen to follow exclusive diets, supplements are a good way to ensure you're not missing out on your micros.
