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

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.

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'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.

Have been taking this supplement for years, notice a clear difference in how i feel when I don't take it for a while, and can see the improvement on my labs. Also, only iron supplement that I have tried that does not bother my stomach.Clean, high quality ingredients.

No upset stomach or constipation. Absolutely loved this as a postpartum iron supplement. Great formulation!

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.

If you’ve crashed your Ferritin and are looking for a way to increase your levels, this is a great product. TRT friendly.

My psychiatrist’s office offers functional psychiatry in addition to med management, and this was recommended to me by the pharmacist in the office who manages supplements. My ferritin levels are naturally low, and I was struggling to stay consistent with other products I’ve tried. This product has been easy for me to take on the daily and I’ve already noticed an improvement with my brain fog even though I’ve only been on this product for about 2 weeks.
