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. Read more

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.

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. Read more

I don’t ever write reviews, but I had to for these OptiFerin-C pills because just on Day 1 I have dramatically noticed results. I was struggling with energy immensely especially in the mornings when I woke up, and felt like I had been hit by a truck energy wise no matter how much I slept, sometimes 10+ hours and I still felt horrible and getting out of bed felt really tough. So when I took this after some research and saw the vitamin C enhanced absorption I took the chance & purchased—results were day & night difference. My sleep quality is improved and I can sleep 6 hours and feel rested when I wake up. And it is much easier to wake up & get out of bed may I add. I’m no longer dependent on coffee or energy drinks to get my day going. The price doesn’t hurt the bank either. They are small pills and can take on an empty stomach that won’t give you nausea Read more

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. Read more
Everyday Honest Reviews 17—August 27, 2025
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.

I'm not super anemic so I don't notice taking this normally, but the week leading up to my period and during the bioavailability of this becomes very apparent. I have so much more energy during my period compared to not taking it. Great stuff. Read more
