CHristine said they aren't large, so I should be ok, but the side effects are scaring me! Maybe I'll try eating more red meat and spinach for now!
For what it's worth, I took ONE Feosol and it didn't bother my stomach.
The Flintstone's also doesn't bother my stomach.
I would like to recommend two products:
Spatone Iron+. I purchase this on-line from a company call Sea-Bands International (they are out of Rhode Island). There has been a good study done that this iron is very absorbable. It comes from an iron-rich spring in Wales. It is put into packets. You just mix it in some juice and drink it. Absolutely no side effects. A one month supply is $18.99 to include the shipping costs (they FEDEX right to your door). Sometimes I take two packets a day if I can get it in.
Floradix - Can be bought a most health food stores and on-line. This is another liquid iron supplement that has herbs added for better absorption. You take two tsp. per day. It also is gentle but more pricey, IMO, then using Spatone coupled with a daily multivitamin. But, it's fairly easy to get.
High does iron supplements are very harsh. That's why I've gone the route of taking lower dose and just increasing slowly.
Some things to keep in mind: spinach doesn't really work but other greens do. You probably can't eat enough meat to give you what you need once you become deficient. Also, take your supplements away from tea, coffee, or dairy products as they can severely inhibit iron absorption.
If you don't have a celiac issue, try some Total Raisin Bran also. Look for ways to put iron in your diet so you don't have to take those huge doses.
