Get your energy back without upsetting your stomach
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. 💪✨

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.

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.

Great quality
I was afraid to start taking iron supplements orally because of the side effects associated with them. With this one, I’ve tolerated it very well; I haven’t experienced any discomfort. The capsule is small and easy to swallow. I recommend it with prior medical advice.

Gentle on the stomach, though a bit pricey
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

Good and effective!
If you want iron supplements this is probably the best formulation. Doesn’t upset stomach and we did see iron levels improve significantly in a few weeks
Cindy Denton –
Not the same as other brands be careful
Made me very sick vs my usual iron supplement. This has same type and dose of iron but caused a lot of side effects.

Gentle on the stomach and easy to tolerate compared to other iron supplements
In the past, I struggled with iron supplements from other brands, as they consistently caused nausea and discomfort, even when taken after meals. After doing some research, I decided to try this product.I’m very pleased to say that this iron supplement has been completely gentle on my stomach. I have experienced no nausea or urge to vomit, which has been a significant improvement for me.If my next blood test shows an improvement in my iron levels, I would gladly repurchase this product and recommend it to friends or family members who are dealing with iron deficiency. So far, my experience has been very positive.

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.
Hisham Fageeh –
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
Xenia –
Easy to tolerate and doesnt cause side effects.

Some iron supplements constipate. This one does not. It does the job in a gentle way.
