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

Good product, it doesn't cause constipation and I like the fact that it's free of unnecessary fillers. I've been taking it since my second trimester of pregnancy and have tolerated it very well. The size of the pill is small and easy to swallow, no aftertaste and I’ve read this form of iron is easier to absorb

WORTH IT!! I was taking this for a month I started doing one day off one day off and it's working well. I'm also taking vitamin c and have really increased eating more iron rich foods. Within that month I went from 8.4-10! I have PCOS and very heavy periods so I'm very anemic and this has been helping tremendously. I haven't reached a point where I feel the energy coming back but I don't look nearly as dead as I did before lol.. No issues at all with my stomach/constipation which is really nice! I'm even able to take it first thing in the morning on an empty stomach and no issues. GIVE IT A TRY!

This iron supplement is fantastic and raised my severely low iron levels to normal in just three months of taking daily. I have a very sensitive stomach, as well as IBS-C and this doesn't bug my stomach at all. I take it every morning either on an empty stomach or with a bit of apple sauce and wait an hour before any caffeine and it works amazing. Very satisfied and worth the price.

I have been taking these for about 2 weeks, and I'm very happy it didn't upset my stomach or cause any bowel movement issues. I am 7 months pregnant and needed to supplement iron but my current vitamins were really hard to take, and get me very nauseated. I changed for some isolated forms, and this iron supplement has been great, small pills, easy to swallow, and no bad effects.

My girlfriend's iron is really low and she's been suing THORNE Iron Supplement for a while now. They seem to be working, but you have to be consistent with taking it or your iron levels will still be low. There a lot of supplements out there but we learned that bisglycinate form of iron is more absorbable and much gentler on the stomach compared to traditional iron supplements.The capsule is small and easy to swallow, with no unpleasant aftertaste. After consistent use, I’ve noticed an increase in my energy levels, which is a clear sign that it’s helping boost my iron levels. Plus, there are no unnecessary fillers, making it a clean supplement option for those who are health-conscious.Pros:Enhanced absorption: Bisglycinate form is gentler on the stomach.No digestive discomfort: Doesn't cause nausea or constipation.Small, easy-to-swallow.No fillers or artificial ingredients: Clean formulation from a trusted brand.Cons:Price: It’s more expensive than some other iron supplements on the market.Lower dosage frequency: May not be suitable for those who need a higher dose of iron per day.

My iron & ferritin levels were extremely low. In the past, iron supplements gave me bad constipation, so was not looking forward to taking supplements. I need to take these twice a day & to my surprise, they not only don’t cause constipation, but have actually regulated my bowel movements - shocker !!!! It’s only been a month, so don’t know if it’s raised my levels yet. It’s better to take them in an empty stomach, but that does bother my stomach, so I take them with food. I’ve also added Vitamin C. Very pleased with these supplements.Edit: after a couple more weeks I had to quit taking them. I had bad diarrhea! I waited 2 weeks & tried taking 1. I got diarrhea about 2 hrs after. It did bring my iron & ferritin up to normal.

This product works well for me, with no negative side effects. It has brought my hemoglobin back up within normal range.Unfortunately, I had left a negative review in error, meant for a different item and seller, but can't figure out how to retract it.

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!
