For me, taking a mulitivitamin is very important to my health. I feel that by taking a multivitamin, I helping myself stay healthy.
There was a time when I would spend between $7 for brand name vitimins and not feel like I was getting my monies worth.
One day while at Walmart, I saw Women's One Daily by Equate and decided to try it. They were a reasonable price and looked the same as the other store brand vitamins I was buying. Plus, instead of the standard 60 day supply, I get 100, that is a little over 3 months of vitamins for such a small price. They also have calcium, iron, and zinc.
With these vitamins, you take one when it is convenient for you (I usually take mine in the morning with my toast). Within about 1-2 hours, I feel great. I have been taking these vitamins for about 2 months and I still feel great.
The only complaint that I have with them, is that you need to eat something before or while you take them otherwise they make you feel nausiated.
