THORNE - Iron Bisglycinate - 25 mg Iron Supplement for Enhanced Absorption Without Gastrointestinal Side Effects* - NSF Certified for Sport - Gluten-Free - 60 Servings

I’ve been really happy with this iron supplement so far. 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.

Excellent iron supplement. Thorne Iron Bisglycinate stands out for its high absorption and, most importantly, for being very gentle on the stomach, unlike other forms of iron. It has not caused me nausea or constipation, which is a big plus. The brand’s quality is noticeable: vegetarian capsules, clean ingredients, and an appropriate dosage. Ideal for people with iron deficiency, mild anemia, or anyone looking to maintain healthy iron levels without unpleasant side effects. In addition, the 60-capsule bottle is practical and lasts a good amount of time. I will definitely keep purchasing it and highly recommend it to anyone looking for an effective and well-tolerated iron supplement. 💪✨

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.

I tried other iron supplements but they made me have stomach problems and my ferritin wasn't improving. This supplement has been great, no stomach issues and ferritin is finally going up.

I switched to this specific brand after reading that iron bisglycinate is supposed to be much easier on the digestive system, and honestly, the difference has been night and day compared to the cheap ferrous sulfate tablets I used to buy. These capsules are quite small, making them very easy to swallow, and I haven't experienced any of the dreaded nausea or constipation that usually plagues me with iron supplements. I really appreciate that Thorne is NSF certified, which gives me some peace of mind regarding purity and ingredients. That said, the cost is significantly higher per serving than what you’d find at a standard drugstore, which is the only reason I’m docking a star. However, if you have a sensitive stomach like I do, the extra expense is probably worth it to avoid the discomfort

Got this to help correct some nutrition gaps as I was doing a vegetarian keto diet for a bit. 25mg (139% of the RDA seemed like a good amount; enough to help and no so much I would tix myself. Capsule is small and easy to take, and it works well (labs are now good). I like this brand a lot; nice quality, fair price. Recommend.

I bought this for my grandmother who is doing chemo and has anemia, she has also been having stomach issues along eith everything else. I am extremely happy with it, it doesnt cause her any digestive issues and her iron levels we up withing just a couple of weeks of taking this!! She is still low due to chemo but the iron levels are better and it stopped her from having to get an infusion! My aunt heard I got these for her so she ordered them for my great grandmother who is also anemic and the doctor prescribed her iron, she didnt want to give her the prescription because of the possible side effects so she went with these and her numbers have gone up as well and without digestive issues!!! These are GOLD! So thankful for these!!

This is a great iron source but remember it needs to be taken on an empty stomach and with a vitamin C for proper absorption ,so best 2 hrs before you eat like when you first get up.

My favorite iron 👍🏻👍🏻👍🏻good for stomach. Fast delivery ⭐️good package ⭐️affordable price ⭐️ Thank you Seller

Good product, good price !

I’ve tried so many supplements over the years, and most of them have upset my stomach. This one is a game-changer! I started taking it a few weeks ago, and it’s been nothing but smooth sailing. No discomfort, no bloating, and no queasiness – even when I take it on an empty stomach.

This is the best supplement among the several I tried. I increased my hemoglobin levels from 110 to 130 in one month in the third trimester of pregnancy when doctors prescribed IV which I refused. I was taking 4 pills every second day with vitamin C. No side effects on stomach and no constipation

I’m very satisfied with the experience. The product arrived in good condition, properly packaged, and securely sealed. Everything was exactly as expected.
