Great Iron Supplement at a Great Price

My doctor discovered I have an iron deficiency and instructed me to start taking daily iron supplements. After a bit of research, I decided to purchase the 21st Century 4-pack from Walmart. I go back for more bloodwork in three months and feel sure my iron will show an improvement, after using this supplement. The product is packaged in very large bottles, especially for only 60 pills each. This works out at about a 2 month supply per bottle and that works great for me. Only time will tell, but I am very happy with my purchase and recommend this supplement to others.
