Review: Thank you ♥️😍❤️👏🏼🔥💪 - I absolutely love Throne Iron vitamins! I’ve tried other iron supplements before, but they often upset my stomach or had a metallic taste. These are completely different—super gentle, easy to swallow, and no unpleasant aftertaste. Within a couple of weeks, I noticed a real difference in my energy levels and overall well-being. I feel less fatigued and more focused throughout the day. Plus, I appreciate that Throne uses high-quality, clean ingredients without unnecessary fillers. If you’re looking for an effective iron supplement that’s easy on digestion and actually works, this is the one! Highly recommend.
Review: Gentle Iron That Actually Works Without Side Effects Finally Found an Iron Supplement I Can Tolerate - After struggling with iron deficiency for years and experiencing terrible digestive issues with traditional iron supplements, I was hesitant to try yet another product. However, THORNE's Iron Bisglycinate has been a complete game-changer for me. The chelated form truly delivers on the promise of enhanced absorption without the gastrointestinal distress that plagued me with other iron products. What sets this apart is the bisglycinate form - iron bound to the amino acid glycine. This makes it much gentler on the stomach while actually improving bioavailability. I take it on an empty stomach without any nausea, constipation, or stomach upset that I experienced with ferrous sulfate supplements. This alone makes it worth the premium price. The 25mg dosage is perfect for maintenance and gradual improvement. My recent blood work showed steady improvement in iron levels after three months of consistent use, and my doctor was pleased with the progress. I have more energy throughout the day and don't experience the afternoon fatigue that was becoming problematic. THORNE's reputation for quality and third-party testing gives me confidence in what I'm taking. The capsules are easy to swallow, and the bottle is clearly labeled with expiration dates and batch information. No artificial colors, flavors, or unnecessary additives - just pure, effective iron supplementation. While more expensive than drugstore iron supplements, the superior absorption and lack of side effects make this significantly better value in terms of actual results and tolerability. Highly recommend for anyone who needs iron supplementation but has struggled with digestive issues from other products.

## Questions & Answers

**Q: are these large or small like regular iron pills?**
A: The Iron Bisglycinate is a small capsule measuring .709 inches in length.

**Q: does this contain any vitamin c ?**
A: No it does not, it just has the iron by itself, which I like.
I just take my vitamin C separately for maximum  absorption.

**Q: Country of origin**
A: 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.

**Q: 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?**
A: 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.
