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

Excellent results
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

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。

Fixed my SEVERE iron deficiency!
I recently started seeing a functional medicine doctor to address some issues I've been having and the first they had me do was a full blood workup. When the results came back one of the most glaring issues was my blood iron (ferritin) level. Ideal levels for a woman my age should be 100-150+ ug/L. My level was 18!! The doctor asked me how I managed to get out of bed in the morning and how I can go up and down stairs without fainting, let alone live my life! It's amazing how you can get used to such a poor quality of life when it creeps up on you and you don't know any different. I immediately started taking iron at triple the recommended dose to make up for my severe deficiency and stop the 'iron leak' I seem to have in my body. After bouncing around between a few different supplements, I have settled on this one and I love it! I take 2 per day (that's what my doctor recommended even though the bottle says 1) and I no longer get dizzy and light headed, I don't bruise as easily as I used to and I just feel so much better over all! If you're deficient in iron, some of the symptoms you might experience are fatigue, dizziness, shortness of breath, difficulty concentrating, difficulty regulating body temperature or often feeling cold, pale skin, heart palpitations, shortness of breath, headaches, hair loss, restless leg syndrome, itchiness, more frequent bouts of illness and ringing, hissing or buzzing in your ears. My doctor says almost EVERYONE is deficient in iron, so this might be something you should take even if you're NOT experiencing these symptoms! One of the reasons I chose this particular brand is because it uses a chelate which is more highly absorbable by the body than cheaper carbonates, oxides, sulfates and phosphates and it doesn't have a bunch of crap additives in it. Additionally, the pills are TINY and super easy to swallow! I use some other Thorne supplements as well and really like them. That being said, not ALL of Thorne's stuff is the best of the best, but when it comes to my iron levels, this has worked wonders and I can definitely recommend! I sincerely hope this review has been helpful to someone else! And yes, I pay full price for this. I get it monthly in my subscribe and save. Feel free to ask any questions!

Gentle on My Sensitive Stomach
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.
