Works great and I can take on an empty stomach.

Posted by Reviewer1498973 on Apr 06, 2012

I started taking this after I could not find Slow Fe in pharmacies. I raised my Ferritin from 15 to 112 in 3 months by taking Enzymatic Therapy Ultimate iron 2 pills 1st thing in the morning and nothing but water for the next 2 hours (found this suggestion on iHerb customer review). I also took 2 pills of 21st Century Slow Release. I have also taken this product on an empty stomach with no issues. My doctor was amazed. We struggled for over one year trying to raise my Ferritin levels. Can not beat the price.

Tummy ache

Posted by 5643032578698079236 on May 06, 2012

My daughter is iron deficient and started taking these iron pills. She developed a stomach ache. The doctor told her to take it at night or a half an hour before eating. Works fine now.

They don't bother my digestive track

Posted by Reviewer2062768 on Oct 30, 2012

I don't know why no one seems to carry slow fe anymore, but I haven't been able to find any. I bought these hoping for the best and they delivered.

I am anemic and have horrible responses to iron pills. I have even tried iron water will poor results (it tasted horrible as well), but this product is great! Can't believe I never heard about it till going on iherb! If you need iron in your life, purchase this. You won't regret it.
