Hemoglobin requires iron to develop and function. Iron helps to support amino acid metabolism and synthesis, all of which help support muscle and cognitive function. Iron deficiency is one of the most common nutrient deficiencies worldwide. It most often affects pregnant women, infants and young children, women with heavy menstrual bleeding, and frequent blood donors. Although iron is abundant in red meat, beans, and dark green leafy vegetables, significant parts of the population do not consume enough of these foods to help maintain normal iron levels. This is especially true for vegetarians. Therefore, a daily supplement of iron may be essential to maintaining a normal, healthy life, but not all iron supplements are created equal. Because of its higher solubility, a form of iron called “ferrous iron” is generally known to be more bioavailable and therefore more effective.

No stomach upset
Typically iron supplements upset my stomach. These are great and do not cause stomach upset. I always take them with vitamin C. Best brand if you need iron.

My new regular!
I was taking Slo Fe because they work without giving me extremely smelly gas all day. However, the packaging itself was enough to make me find another brand. These are easy to get to and great for prefilling my weekly meds box. They work great with no side effects whatsoever and for a cheaper cost! I will be ordering them from now on!UPDATE: They work TOO well! LOL I’ve been taking these for 2 years now and my iron levels are great despite having a ferritin deficiency, but my red blood cells count is too high now. No worries, I just half these pills with a pill cutter.

Easy on the stomach.
I have trouble with regular iron, but no problem with this slow-release product. I’ve been diagnosed anemic and taken these for several years now with no stomach issues,

YEA!
I am required to take a slow-release iron because anemia runs in my family and without it, I become anemic quickly. After being price gouged by Wal-Mart and having success finding the antihistamines on Amazon, I decided to search for a good slow-release iron and voila. So far, they work great and I still feel like my old perky self.

I really couldn’t say what flavor these have.
I was asked but I would have to say they don’t have any flavor. I swallow them whole. I have a problem with iron. I take it twice daily. It can really bother my stomach so I was taking another brand for years but they are packed so you have to remove each one from a plastic bubble and it really got to be annoying. So I looked around and decided to try these. I am more than pleased. They work as well as the other kind I was taking and I don’t have to remove them from some uncooperative plastic bubble thingy and no upset tummy either. Great product.

Personally I like these pills
Personally I like these pills, at least the quantity to cost since I was buying the CVS generic brand that cost $20 for 30 tablets and these have more milligrams. The downside for me is the metallic taste I have in my mouth, it’s awful. I’m sure it’s a chemistry thing, they just don’t mix well with me, but otherwise I’d recommend them.
