are these large or small like regular iron pills?

The Iron Bisglycinate is a small capsule measuring .709 inches in length.

does this contain any vitamin c ?

No it does not, it just has the iron by itself, which I like. I just take my vitamin C separately for maximum absorption.

Because it is proprietary and confidential business information, Thorne does not disclose the country of origin of its raw materials. Thorne tells us: "Thorne Research sources its ingredients from around the world. However, what is much more important than the country of origin of an ingredient is the testing that is done on that ingredient when it is received by the manufacturer. Thorne Research does not rely on the Certificate of Origin from an ingredient supplier. Instead, Thorne Research tests every single ingredient in our own in-house laboratory, regardless of the ingredient's country of origin, to verify the ingredient's identification, purity, and quality." If you would like more information, we suggest you contact Thorne Customer Service directly at 800-228-1966.

If this has 139% of your daily value for Iron, isn't that a bad since it exceeds the daily value, and there's iron in some foods?

The nutrient content in Thorne’s nutritional supplements is higher than the FDA’s Recommended Daily Allowance (RDA) because the RDA guidelines are designed to prevent a deficiency rather than providing you the amount you need to correct a deficiency or support optimal health. Often, individuals who require iron supplementation are already in a deficient state, and a correction of a deficiency requires a higher amount of iron than what would be required to prevent the deficiency as is provided by the RDA.
