Pure Encapsulations OptiFerin-C - for Red Blood Cells & Energy - Iron Absorption Support - Energy Supplement* - Vitamin C Enriched - Gluten Free & Non-GMO - 60 Capsules

The gentlest iron supplement I have found. And I have tried a lot.Finding something that did not constipate and could still be taken regularly has been a search.I found this product a couple of years ago and have been using it steadily since.It’s not a real high dose, but seems to be very sufficient from my body. I can take one capsule daily and still function with regular bowel movements.The real great news is after steadily using for two years my doctor just ran my blood and my iron level is Good!After failing so many other combinations and brands, it’s great to have something easy to take, small capsule, minimal complications if any. Highly recommend if you need an iron supplement.

I've been using Pure Encapsulations OptiFerin-C for 5 years now and it's been a great iron supplement. It's gentle on the stomach, has vitamin C to help with absorption, and it's clean — no gluten, GMOs, or unnecessary fillers. If you're vegan or can't tolerate animal-based products, this is one of the best options out there.That said, if you can take animal-based supplements, I personally think beef liver supplements are even better. They don’t just have iron — they also naturally come with a ton of other nutrients your body needs, like vitamin A, B12, B-complex, zinc, copper, selenium, and etc. All of it is in a whole-food, highly absorbable form.Still, OptiFerin-C is a solid pick if you're looking for a vegan or non-heme iron option that works. It’s helped me keep my iron levels up without side effects, and I’ll keep using it.

If you are tired of vitamin supplements which taste and smell of plastics and not at all of vitamins, here's a true one. I am so grateful for a supplement that works, and works well. After a lifetime of excellent iron levels, I now require iron and D3 just to keep me up and out of bed. The vitamin C is to help the iron work. I had only seen iron and C together previously as a prescription.

Great! doesn't constipate me during pregnancy.

These capsules are easy to swallow and do not cause any GI issues. My iron levels have increased significantly since taking this product daily.

I ordered these because my iron was a little low. I have been feeling more energetic since I’ve started taking them, but I hoped that they wouldn’t be unpleasant to take. I’ve had iron supplements that didn’t cause issues before, but these aren’t it. I take them right before bed, but I still wake in the middle of the night burping iron taste. That’s pretty typical, so know these aren’t buffered in any way.

This is the best brand I've found for any supplement

My doctor recommended these. This brand has always been a go to for supplements. These were a little too harsh on my stomach though.
