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've been using Pure Encapsulations OptiFerin-C and I'm really impressed with the results! It's gentle on my stomach, and I noticed a boost in my energy levels shortly after starting it. I appreciate that it's enriched with Vitamin C to help with iron absorption, and the fact that it's gluten-free and non-GMO gives me peace of mind. My red blood cell levels have improved, and I feel more energized throughout the day. Highly recommended for anyone looking for a reliable iron supplement. I’d rate this product five stars!

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.

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.

Worth the money!

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

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