Review: Highly Effective Iron Supplement – Huge Difference for My Wife - My wife has mild anemia, and these have helped her tremendously. They’ve made a noticeable difference in her energy levels, and she can tell right away when she stops taking them. She’s been using them for close to 3 months now, and unlike other iron supplements, she’s never had any stomach issues or discomfort with these. If you’re looking for an iron supplement that’s gentle on the stomach but truly effective, this is definitely worth trying.
Review: Increases ferritin. Zero side effects. Take 3 daily, cut pills to facilitate disintegration. - 23 days of proferrin, and my ferritin has gone from 18 to 32. No side effects to speak of, except that I can run with energy again. It is such a gift to feel my strength again, like youth. I'm continuing with this. I was taking iron bis-glycinate, but while effective when taken on an empty stomach, I felt like I had swallowed a balloon. When I took iron bis-glycinate with meals (away from calcium), it was not effective after 4 months of use. I take proferrin with meat stock first thing in the morning; apparently it absorbs better in the presence of amino acids: "free amino acids as cysteine, lysine and histidine enhanced heme and ionic Fe absorption in experimental models". Also iron absorption is apparently not sensitive to calcium in doses of less than 800 mg at a time. "Calcium does not inhibit the absorption of 5 milligrams of nonheme or heme iron at doses less than 800 milligrams". Where other forms of iron are inhibited by phytates and polyphenols, heme iron is not. Lastly, I understand (hopefully correctly) that heme iron may cause less oxidative stress than other forms. I hope that as a result, it lowers the risk of Alzheimer's disease associated with iron supplementation. Update: I was taking 1 pill per day at the time of this review. Since then my ferritin levels dropped to 20, so I began taking 2 per day. Fortunately I did this without any gastrointestinal upset, but unfortunately, 2/day only brought my ferritin up to 21 (I got this blood test result back today). Iron repletion is obviously extraordinarily complex. I'm baffled by it. Update July 2018: My ferritin dropped to 20, then to 17, 13, and finally to 10 while taking approximately 7 proferrin per week. During that time I tried alternating schedules, taking it with broth, lactoferrin, pepsin. Nothing worked. Once my ferritin had dropped to 10, I decided to take 30 mg per day, which is apparently the max you can take without causing expression of Hepcidin (prevents the uptake of iron). Also, I had been inspecting my stool (I know, gross...) and found pockets of dry black powder from undissolved proferrin pills. These pills look like black charcoal on the inside, which is probably why the coat is colored (green). Obviously absorption won't happen if they haven't dissolved. I started taking 3 pills (30 mgs) each morning, all at once, on an empty stomach, away from calcium. Most importantly, I cut each pill in half before taking, which seemed to help disintegration because I found no more black powder in stools. As a result, my ferritin climbed back up to 17 after 1 month of this routine. I'll continue checking ferritin levels each month until it has reached a steady state. Hopefully no more downturns. Update November 2018: My monthly ferritin levels have continued to rise on the schedule of three pills per day, cut, on an empty stomach, and away from calcium. Here are my ferritin results (ng/ml): August (16), September (21), October (25), and November (40). Awesome. Feeling so much better.

## Questions & Answers

**Q: Why are there such bad ingredients?? Colors?!!**
A: Hi There! Thank you for the question! Currently, we also make Proferrin Clear which is free from all colors/dyes and is also available on Amazon. Proferrin Clear and Proferrin ES have the exact same amount of Heme Iron.
Best,
Team Proferrin

**Q: Is it vegetarian?**
A: No, it is not vegetarian. It is derived from the hemoglobin of cows. It has been amazing for improving my hemoglobin.

**Q: Can you please tell me what the expiration date is on this bottle?**
A: Its on the side of the bottle

**Q: Anyone know why this product contains so many unhealthy inactive ingredients (artificial colors, talc, titanium dioxide, polyvinyl...)?**
A: Hi there! Thank you for the question! We do have a product called Proferrin Clear that comes in a gel capsule. The gel capsule does not have the coating on it that the ES tablet does, so it has a smaller ingredient list with only 4 ingredients. Both the Proferrin Clear and the Proferrin ES have the same amount of Heme Iron.
Thanks,
Team Proferrin
