Gentle, Effective, and Easy
I've tried several iron supplements over the years, and this one has been by far the easiest to tolerate. THORNE Iron Bisglycinate provides a well-absorbed form of iron that doesn't leave me dealing with the stomach discomfort or constipation I've experienced with other brands. The capsules are easy to take, and I've noticed a positive difference in my energy levels and overall well-being. The quality is exactly what I've come to expect from Thorne, and I appreciate that it's NSF Certified for Sport and gluten-free. If you're looking for a reliable iron supplement that's gentle on your digestive system, this is an excellent choice!

Gentle Iron Supplement That’s Easy on the Stomach
I’ve had a great experience with this iron supplement. The capsules are easy to swallow, and unlike many other iron supplements I’ve tried, this one is very gentle on my stomach. I didn’t experience the usual digestive discomfort or constipation. I appreciate the high-quality ingredients and trust the Thorne brand. After taking it consistently, I noticed an improvement in my energy levels, and it has become part of my daily routine. The bottle lasts a good amount of time, and the quality makes it well worth the price. If you’re looking for a well-tolerated, high-quality iron supplement, I would definitely recommend giving this one a try.

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 product.
I’ve been taking it for about a week. Seems to be helping my RLS. And I have no side effects. I will continue purchasing this product in the future.

Only iron supplements my GI has been able to handle
I had severe anemia. Doctors told me take FE 65mg elemental iron. I could not tolerate those, even the "slow FE" type. I did my own research on brands, types of iron, bind agents, and helpers to potentate the iron. My symptoms were dizziness, fatigue, vertigo, nausea, neuropathy in my hands, constant stomach ache, and inability to eat much. I told the doctors my stomach didn't do well on the 65mg typical supplement. Based on the information I read (some from Thorne's own marketing team admittedly) I chose this product. So far, so good. Well tolerated and many of the above symptoms disappeared or abated. Why only 4 stars you ask, because with 25mg elemental iron this isn't meeting the dose I need to increase my blood iron levels a much a needed. To be fair, that my bodies fault for not tolerating 65 mg of elemental iron. My doc told me this wasn't good enough if it didn't have 50-65 elemental due to my need. It is obviously improving my anemia due to the rapid relief from symptoms I had for years. The doctor showed me a graph of the last 10 year iron levels from lab work. The wise in iron indeed is not dramatic yet. After reading reviews here I asked the nurse practitioner if I could try taking two of these a day before going to the harsher formulations. She said she didn't know and couldn't immediately find any reference on this formulation that met the office's standards for peer reviewed, published data. We know we often won't find that for supplements since there are no obscene profits or patents on vitamins and supplements (it's a crime they don't tell us the true requirements for vitamin D3 when 10,000IU a day could significantly boost immune in northern states in the winter). The NP said "I advise you to take one with 65mg. I can't say for sure if you should go off label with this formulation." I told her: "I'm going to try it because this has been a game changer in how I feel and has nearly no bad side effects. Just a couple days in to 2 a day. It bothers my stomach a bit more. In fact, about twice as much as one pill (go figure). I'm going to stick with because I think this 2 pills of Thorne Research - Iron Bisglycinate will bring 50 mg Iron Supplement in an effective formula. I just hope it isn't too much. I've bought several Thorne products and I am growing fond and trusting of the brand. I recommend you try these but please get clear info from doctors on severity of your need. The NP suggested I do more research on Iron Bisglycinate and other improved absorption and we will monitor the blood iron levels. FWIW I started this treatment (with one pill) at the same time as Vitamin B12 Cyanocobalamin injections. There was some magic one/two punch with the two treatments that seemed to wipe away years of pain and discomfort. Check you B12, Iron, D and other critical vitamins/minerals. Sometimes the answer is a relative affordable over-the-counter readily available supplement.

Wonderful alternative - little to no nausea
Was anemic and not doing well taking my prescribed iron pills until I read how the bisglycinate form is gentler on the stomach. Even taking them just before bed was making me so nauseous with the ferrous sulfate I had been using. I can now take these daily even in the morning and with or without food. That's helpful because you shouldn't take too soon before or after a meal or supplement with a lot of calcium.

Oxidize quickly
These are gentle on the stomach but beware of oxidation. I had them for around a year and by the end and after comparing to the new pack, these were completely oxidized (brown) and probably completely ineffective. Best to use them up quickly.

飲みやすく続けやすい鉄分サプリ。毎日の栄養補給に
毎日の食生活だけでは鉄分が不足しがちだと感じ、継続しやすいサプリメントを探して購入しました。ビスグリシネート鉄を使用しているためか、一般的な鉄分サプリよりも飲みやすく感じ、毎日無理なく続けられています。カプセルも大きすぎず、水と一緒にスムーズに飲めました。 1日1カプセルで必要な鉄分を手軽に補えるので、忙しい日でも習慣にしやすい点が気に入っています。60粒入りで約2か月分あるため、コストパフォーマンスも悪くありません。 一方で、海外製サプリということもあり、価格は国産製品と比べるとやや高めに感じました。また、サプリメントは即効性を期待するものではなく、継続して取り入れることが大切なので、数日で変化を求める方には向かないと思います。 品質や飲みやすさを重視したい方には選択肢の一つになるサプリメントだと感じました。

Iron Without the Tummy Troubles—Finally!
Thorne Iron Bisglycinate is a total game-changer for anyone who needs an iron boost but dreads the usual stomach drama. It’s gentle on digestion—no cramps, no nausea, and no awkward rush to the bathroom (you know what I mean). I’ve been taking it daily, and my energy levels have noticeably improved, especially during workouts and long days. The capsules are small and easy to swallow, and it’s NSF Certified for Sport, which gives me peace of mind that it’s clean and free from junk. Plus, it’s gluten-free, so no worries for those with sensitivities. The only downside? It’s on the pricier side for an iron supplement, but the lack of side effects makes it worth every penny. Also, you’ll need to pair it with vitamin C-rich foods or drinks to maximize absorption, but that’s an easy fix (hello, orange juice!). If you’re tired of iron supplements that make you feel worse than being anemic, this one’s a must-try. It delivers results without any of the hassle. 4.8/5
