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

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.

i found out i was possibly iron deficient by telling a nutritionist about my tomato cravings and she said that's a classic sign in women, esp menstruating or pregnant. all i can say is, one week i'm drinking bloody maries like they're water, then if i take these the cravings disappear, so i know they're working. that wasn't the case when i took vitamin C alone. they don't upset my stomach at all and actually make me a bit sleepy so i take them at night.

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.

This iron supplement was recommended to me by a healthcare professional, and I’ve now purchased it twice. My lab tests show that my iron levels are improving, so I feel confident it’s doing what it’s supposed to. The capsules are small, easy to swallow, and have no aftertaste. I usually take them on their own and try to pair with a food source of vitamin C for best absorption. The price feels fair for the quality, and I plan to continue repurchasing when I need to.

If you’ve crashed your Ferritin by donating blood, and are looking for a way to increase your levels, this is a great product. TRT friendly. I was at 31, and within one bottle at 3 pills a day, combined with orange juice for vitamin C absorption, I was able to increase my ferritin to 151. I no longer have brain fog, have a hard time remembering things, or having a hard time getting words out.

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.

No upset stomach and my iron levels are improving since I’ve begun taking it.

Delivered very quickly and no issues with the product. Great health benefits!
