Effective and Great Value
The 21st Century Slow Release Iron Tablets have been really helpful. They helped improve my anemia, and I’ve noticed a real difference in my energy levels. The price is great compared to other brands, and the slow-release formula is gentle on the stomach. Definitely a solid choice if you need iron supplements that actually work.

Gentle and Effective Iron Support
I’ve been taking the 21st Century Slow Release Iron Tablets (60 count, pack of 2) daily for about six weeks, and they’ve been a steady addition to my wellness routine. The low-dose, slow-release formula is easy on my stomach—no nausea or digestive upset like I’ve experienced with other iron supplements. I just take one with breakfast, and it seems to help keep my energy steady, especially on busy afternoons. What really stands out is the value and convenience. Between the two bottles, I’ve got a good three months’ supply, so I don’t have to reorder constantly. The tablets are easy to swallow and the packaging is straightforward. If you’re looking for a budget-friendly iron supplement that delivers gentle, sustained support without stomach issues, this one is a solid pick.

Great product and great price
Love this brand and product! My iron level was on the lower side- 14.7- and ever since I started taking these my energy level has risen as well as my iron level each time I have bloodwork done. I'll defintely be reordering.

Never feel sick!
This is a really good iron supplement! Most others make my stomach hurt, even the ones that say “gentle,” but this one is fantastic. I never feel sick. TMI: However, I do get pretty constipated 😞 so I have to start increasing my fiber intake or take a stool softener with it. I’ve been using it for a month now and I’ve seen and felt the benefits already. I no longer feel like I’m freezing all the time, my nails are actually getting stronger instead of breaking and being brittle, I’ve stopped getting dizzy spells when I stand up, and it has helped with my menstrual cycle issues. Highly recommend these! But if you’re prone to constipation when taking iron, you’ll need fiber or a stool softener for sure.

Iron supplement without the GI impact
These are great because they didn't cause gastrointestinal issues like the other iron supplements I tried, and they are significantly cheaper. They did raise my ferritin and hemoglobin levels after a few months of use.

Amazing
Amazing. I am a Swiffer user mostly because I'm too old to get down on the floor. I absolutely love these new mop heads. I've actually just ordered another set for a family member. I'm pretty sure I will never buy another Swiffer pad again. The only thing I would say is before moping, make sure you do a good sweep/vacuum because the mop head is not great at picking up dust bunnies and/or hair etc. I was able to not only mop the bathroom floor but first I was able to give the toilet bottom a quick cleaning and this mop head got into all the crevices WAY better than a pad does. I used a bucket of water so I was able to do multiple quick refreshes and just cannot do that with the pad as well. Easy to get on/off, fits well and overall well made. Thank you for a good product.

Works well and much less expensive than name brand!
This was my 2nd purchase of this item after my doctor had told me to start taking slow release iron. This is much less expensive than the name brand, and it works just as well.

I love these pills. Gentle on the tummy and such great value for money. I get them for my parents as well. Used to get them on an Amazon subscription in the US. And was pretty miffed that I couldn't get them in Australia. But nowwww. I can. Yaaaaayyyy.
