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. 💪✨

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 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.
