It’s easy to take and hasn’t upset my stomach like other iron supplements I’ve tried, which was a big concern for me. I’ve been using it consistently and have noticed an improvement in my energy levels. It feels like a good quality product, and I like that it’s gentle but still effective. The only downside is the price is a little higher than some other options, but for me it’s been worth it. 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. ## Features - Well-Absorbed Iron: Provides 25 mg of elemental iron per capsule in a non-constipating, well-absorbed form as iron bisglycinate - Symptoms of Low Iron: Nearly 1 in 3 adults in the U.S. may have low iron levels, which can manifest as weakness, fatigue, shortness of breath, dizziness, drowsiness, irritability, infrequent menstruation, and more - Blood Support: Dietary iron is essential for the formation of new red blood cells, especially important for women of childbearing age, after blood loss from surgery/injury, or for those who follow vegan/vegetarian diets* - NSF Certified for Sport: Tested for compliance with label claims and to ensure the absence of nearly 300 substances banned by many major athletic organizations - Trusted: Thorne is chosen by champions and trusted by 100+ professional sports teams, a proud partner of U.S. National Teams, and the #1 recommended clinical brand by health-care practitioners (2023 Health-Care Practitioner Seller Survey) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0797GZDZL | | Age Range Description | Adult | | Allergen Information | Dairy Free, Gluten Free, Soy Free | | Best Sellers Rank | #384 in Health & Household ( See Top 100 in Health & Household ) #2 in Iron Mineral Supplements | | Brand | THORNE | | Brand Name | THORNE | | Customer Reviews | 4.7 out of 5 stars 8,109 Reviews | | Diet Type | Vegetarian | | Flavor | Unflavored | | Item Form | capsules | | Item Weight | 0.02 Pounds | | Manufacturer | Thorne Research | | Manufacturer Part Number | M226-R | | Material Type Free | no artificial flavors,soy free,gluten free,dairy free | | Model Number | M226 | | Number of Items | 1 | | Primary Supplement Type | Iron | | Product Benefits | Sports Performance | | Supplement Formulation | Individual Supplement | | UPC | 693749003458 | | Unit Count | 60 Count | ## Product Details - **Brand:** THORNE - **Flavor:** Unflavored - **Item Form:** capsules - **Primary Supplement Type:** Iron - **Unit Count:** 60 Count ## Images ![THORNE - Iron Bisglycinate - 25 mg Iron Supplement for Enhanced Absorption Without Gastrointestinal Side Effects* - NSF Certified for Sport - Gluten-Free - 60 Servings - Image 1](https://m.media-amazon.com/images/I/61WJbpcBTkL.jpg) ![THORNE - Iron Bisglycinate - 25 mg Iron Supplement for Enhanced Absorption Without Gastrointestinal Side Effects* - NSF Certified for Sport - Gluten-Free - 60 Servings - Image 2](https://m.media-amazon.com/images/I/71BUgn81DFL.jpg) ![THORNE - Iron Bisglycinate - 25 mg Iron Supplement for Enhanced Absorption Without Gastrointestinal Side Effects* - NSF Certified for Sport - Gluten-Free - 60 Servings - Image 3](https://m.media-amazon.com/images/I/71zNUal9cDL.jpg) ![THORNE - Iron Bisglycinate - 25 mg Iron Supplement for Enhanced Absorption Without Gastrointestinal Side Effects* - NSF Certified for Sport - Gluten-Free - 60 Servings - Image 4](https://m.media-amazon.com/images/I/81g6Kmv5lvL.jpg) ![THORNE - Iron Bisglycinate - 25 mg Iron Supplement for Enhanced Absorption Without Gastrointestinal Side Effects* - NSF Certified for Sport - Gluten-Free - 60 Servings - Image 5](https://m.media-amazon.com/images/I/81NY5Dt6i1L.jpg) ## 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Finally an Iron Supplement I Can Tolerate *by R***H on April 10, 2026* I’ve been really happy with this iron supplement so far.
