Like everyone has said you need a multi year-round. Just be sure you get a multi that has been tested to dissolve within a time period. Some multis have been tested and they were found to not dissolve for up to an hour, which would place the multi in your intestine where you wouldn't be able to absorb certain nutrients. I trust Universal animal pack and one-a-day. When i am lifting heavy or on certain "supps" i will take 2, one at 6 a.m. with breakfast, then i will break the other one up, half at noon and half at 6 p.m., so i get a steady intake.
