No side effects
I’m feeling stronger after a week. My ferritin levels were pretty low for no apparent reason. Seeing a hematologist next month. In the meantime I’m taking this iron supplement. No stomach pains or constipation. So far, feeling pretty strong and much better!!

Really good!
After trying 4 other irons, I wanna say this one is absolutely worth every penny. The first couple days of reversing out symptoms were rough, my ferritin was decently low and had been for a longggg time. But after that stopped, I started feeling overall better in general, and have seen a great improvement in my labs! I will absolutely spend the money on this iron again and again for the results.

this really works and is easy on the GI system!
Relatively expensive, but the only iron supplement i could tolerate: all the others caused MASSIVE GI upset, nausea, bloating and pain ….and even better, this supplement really works for me, bringing my ferritin from 36 ng/ml to 56 ng/ml in just a few weeks, taking 2-3 capsules per day, usually with food … heme-based [animal-derived] iron is said to be several times more absorbable than non-heme-based iron, and is also said to absorb even better when Vitamin C is taken at the same time … i’ll continue to take this with a goal of ~100 ng/ml

Doubled ferritin in 4 weeks.
Doubled my ferritin in 4 week more than I was able to do in 6 months with ferrous iron. I had sever deficiency and am now feeling a lot better. I also think I’m absorbing other nutrients better since this has zero impact on gut compared to ferrous iron. I’m tracking with monthly tested to know this.

Simple Iron Supplement
This is easy to take and simple to add into a daily supplement routine. I also like that it’s dye-free and made in the USA.

Worked quickly great product but price is to high for quantity
Have been taking these for a week and I feel great can already tell the difference I highly recommend I have tried several Iron pills these are the only ones that have worked me they are easy to swallow and easy on the stomach you can take with or without food and not get sick only negative thing I can say is price is a little high for the quantity you get especially taking them 2 to 3 times a day

So gentle and effective
The only iron I’ve been able to find that doesn’t upset my digestive system or cause gas. This is bovine sourced and not porcine, which I also personally prefer. I do wish the standard formula was also free of dyes, but I appreciate the clear formula choice.

No noticeable side effects.
So far, in about 2 weeks of using this, it’s made a significant difference in my wife’s iron levels per lab reports. She hasn’t had any side effects from it like other supplements, and her saturation and total iron levels have tripled(it was very low before).
