"Iron deficiency is incredibly common in women with PCOS, especially those with heavy periods. But most iron supplements cause terrible digestive side effects that lead women to stop taking them. ProbIron solves this with a gentle, absorbable form paired with probiotics for gut support."

You're Not Broken - You're Running on Empty
If you're exhausted no matter how much you sleep, if your brain feels foggy by noon, if you get dizzy when you stand up too fast - you might be iron deficient. And if you've tried iron supplements before and given up because of the stomach pain, constipation, and nausea - you're not alone.
For women with PCOS, heavy or irregular periods can drain iron stores faster than your diet can replace them. Low iron doesn't just make you tired. It impairs thyroid function, reduces exercise tolerance, affects mood, and makes every other PCOS symptom feel harder to manage.
ProbIron was formulated to solve the iron supplement dilemma. Iron bisglycinate is chelated to the amino acid glycine, making it dramatically more absorbable and gentler on your digestive system. Add targeted probiotics that support both iron absorption and gut health, and you have an iron supplement you can actually stick with.
Individual results may vary. These results are not typical and may not reflect the results you will experience.

New Formula
Why We Upgraded to 299v
We rebuilt ProbIron around Lp299v - the specific probiotic strain and dose used in the published human iron-absorption research.

|---|---|---|---|
| Strain | Lp299v - the specific clinically studied strain | Generic L. plantarum | No probiotic |
| Dose | 10 billion CFU | 2 billion CFU | No probiotic |
| Iron absorption evidence | Matches the dose used in the human absorption trials cited below | Not strain-specific | Relies on iron salt alone |
| Studied in | Menstruating women, iron-deficient female athletes, pregnancy | - | - |
| Common GI side effects | Gentler, lower elemental iron load | Possible | Frequently reported (constipation, nausea, cramping) |
The Research Behind Lp299v
Double-isotope crossover study in women of reproductive age
Compared 10^9 vs 10^10 CFU doses of Lp299v added to an iron-fortified drink, measuring iron absorption.
Hoppe et al., British Journal of Nutrition, 2015
Freeze-dried capsule format, 10^10 CFU
Iron absorption was significantly higher with Lp299v vs placebo (p=0.040).
Hoppe et al., PLOS ONE, 2017
Systematic review & meta-analysis
Pooled data across multiple Lp299v human trials on iron absorption and iron status markers.
Systematic review/meta-analysis, Nutrients, 2019
RCT in iron-deficient female athletes
Lp299v taken alongside iron compared with iron alone.
RCT in iron-deficient female athletes, Nutrients, 2020

Human Clinical Evidence
The Most-Studied Probiotic Strain in the World, for Iron
We didn't pick Lp299v because it's trendy. We picked it because it's the only probiotic strain with repeated, peer-reviewed human trials proving it helps women absorb more iron - at the exact 10 billion CFU dose we use inside every ProbIron capsule.
+29%
More iron absorbed
Iron absorption rose from 17.4% to 22.3% when Lp299v was taken with an iron meal vs the same meal without it (p < 0.05).
Hoppe et al., PLOS ONE, 2017 - freeze-dried Lp299v, menstruating women
+66%
Larger ferritin gain vs iron alone
In iron-deficient female athletes, 4 weeks of Lp299v + 20 mg iron raised ferritin +13.6 µg/L vs +8.2 µg/L with 20 mg iron alone.
Axling et al., Nutrients, 2020 - RCT, iron-deficient female athletes
326
Pregnant women studied
A randomized clinical trial in 326 healthy pregnant women showed Lp299v paired with a low dose of iron helped maintain iron status through pregnancy.
Axling et al., Acta Obstet Gynecol Scand, 2021
30+ yrs
Of clinical documentation
Lp299v is the most clinically documented Lactiplantibacillus plantarum strain in the world, with iron-absorption benefits reviewed by EFSA in 2016.
EFSA Journal, 2016; Probi LP299V® scientific dossier
The published dose matters. Every human iron-absorption trial that showed a benefit used 10 billion CFU (10¹⁰) of freeze-dried Lp299v - the same dose in ProbIron v2. The prior formula delivered 2 billion CFU of a generic L. plantarum, which has never been studied for iron absorption.
Six Studies. One Strain. One Dose.
Statistics above describe the published research on Lactiplantibacillus plantarum 299v as a strain. They are not claims about this finished product. This product is not intended to diagnose, treat, cure, or prevent any disease.

What to Expect
Real change happens gradually. Here's what 50,000+ women have experienced.
Week 1-2
The Tolerance Test
You'll notice the difference immediately - no stomach pain, no constipation, no nausea. Your body begins absorbing iron efficiently thanks to the bisglycinate form and vitamin C co-factor.
Week 4-6
The Energy Return
Many women begin noticing improved energy, less brain fog, and fewer episodes of dizziness. Exercise feels less exhausting. Your body is rebuilding its iron stores.
Month 3+
The Full Rebuild
Ferritin levels climb into healthy ranges. Women report sustained energy throughout the day, clearer thinking, better mood, and improved exercise tolerance. The exhaustion that once felt permanent lifts.
Individual results may vary. Timeline based on customer-reported experiences.
Why Consistency Matters
Repleting Iron Takes at Least 3 Months - Here's Why
Feeling better is just the beginning. Your body needs a sustained, daily supply of iron to refill the deep storage (ferritin) it draws from - and that rebuild simply can't be rushed. Stopping early is the #1 reason iron levels rebound.
Stores Begin Refilling
With consistent daily intake, your body shifts from surviving to rebuilding. Ferritin slowly climbs.
True Repletion
Ferritin reaches healthy ranges. This is the point most women stop too early without a steady supply on hand.
Set it and forget it - never miss a day
Iron repletion is a marathon, not a sprint. A subscription ensures you have a steady supply for the full 3+ months it takes to rebuild your stores - delivered automatically, at the lowest price.

From My Journey to Yours
Why I Created This Formula
I created ProbIron because I was tired of being told to "just take iron" when every iron supplement made me feel worse than the deficiency.
After years of heavy periods from PCOS, my ferritin dropped to single digits. I was exhausted, foggy, and dizzy. My doctor prescribed iron, but every form I tried - ferrous sulfate, ferrous fumarate, liquid iron - caused unbearable stomach cramps and constipation. I'd take it for a week, feel miserable, and stop.
It was a vicious cycle: too iron-depleted to function, but unable to tolerate the supplements that were supposed to help. I knew there had to be a better way.
ProbIron uses iron bisglycinate, the most bioavailable and gentle form of iron available. We added targeted probiotics that support both iron absorption and the gut health that traditional iron supplements destroy. And we included vitamin C and methylfolate to maximize absorption and support healthy red blood cell production.
Because you shouldn't have to choose between building your energy and destroying your gut.

Our Commitment To You
30 days. Real Change Takes Time.
Hormonal wellness isn't a two-week fix. We know that — and we think you deserve a supplement company that's honest about it.
This formula is designed for consistent, daily use. Most women describe the most meaningful changes after 6 weeks or more of daily support. That's why we back every first purchase with our 30-Day Nourished Promise.
If you've taken it consistently for 30 days and you're not satisfied — contact us. We'll make it right.
Take it consistently
As a dietary supplement, for optimal absorption take 2 capsules every second day. Take separately to caffeine and alcohol as well as calcium and zinc supplements. For best results continue using for 90-120 days.
Give it time
Most women describe meaningful changes after 6 or more weeks of consistent use. Hormonal shifts don't happen overnight.
We stand behind it
30 days. If you're not satisfied after consistent use, contact our team. We'll make it right.
30-Day Nourished Promise applies to first purchase only. Contact hello@nourishednaturalhealth.com within 30 days of purchase date. Consistent daily use required.
Give It Time To Work
Why 3 Months Minimum Matters When It Comes To Women's Hormones
Real hormonal change is a gradual process, not an overnight fix. A woman's body works in cycles that unfold over months, so the most meaningful benefits of any supplement show up when you give it consistent time. That's why we encourage at least 3 months of daily use before judging the results.
Eggs Develop on a Long Cycle
The egg you release this month started maturing around 90 to 100 days ago. Nutritional support you give your body today is laying the groundwork for cycles you won't see for months.
Hormones Rebalance Gradually
Female hormones move in monthly rhythms, not days. It typically takes three or more complete cycles for the body to find a steadier, more balanced pattern.
Nutrient Stores Rebuild Slowly
Supplementation works by gently replenishing what the body draws on every day. Those reserves are restored steadily with consistent daily use, not in a single dose.
Consistency is the real secret. Taking your supplements every day for three months or more gives your hormones the steady support they need to find their natural rhythm.
Customer Reviews
Overall rating: 4.7 / 5 from 15 reviews.
The ProbIron has been a game changer for me. As someone with chronic anemia, I was feeling intense fatigue, but after taking this supplement for less than a week, I couldn’t believe how energized I felt! I’m a professional ballerina, and I’ve never felt so strong since taking this iron.
This iron has been very gentle on my stomach, and I think I feel a difference in my energy levels after a month of taking it. One thing I don’t like about it is that I have two toddlers that I’m afraid will open it up because there is no childproof lid on it. I have to be so careful about where I put it since overdosing on iron is one of the most common causes of poisoning in children.
Store owner replied: Hey Katie - appreciate you flagging the cap issue. Our current batch (with the 299V updates) includes a child-proof cap as you mention. 100% still recommend keeping out of reach of children. We appreciate you flagging and for your kind review!
The best Iron source I have found! Nourished Natural Health Probiron doesn’t cause constipation like every other brand I have tried!!!
Got these due to being low on iron. I’ve taken multiple iron supplements before that have all in some way gave me digestive issues. These do not. I have been taking them for about a month now and still no gastrointestinal side effects. I will be getting another bottle for sure.
It's working really great
Only a couple left and since taking them my Blood work has looked a little better! Better than what it was when I took the prescribed iron.
I had record low iron after giving birth and this helped regulate my numbers after an iron infusion at the hospital.
Great addition!
It helped with my energy also.
My iron saturation after 2 years has finally went up after consistently taking these every other day. It was a relief to see that.
It’s still the beginning but so far absolutely loving it and can’t wait to continue
ProbIron was super helpful in getting my iron levels up...at 6wks postpartum it was 13.6! Yay!
Taking this because my iron is normally low. Haven’t had bloodwork done to see if it has helped.
Live it
When I got back my lab results from my second trimester appointment, I found out my red blood cell count was super low. I immediately ordered the Probiron because I love the Nourished Natural Mama supplement and I quickly noticed an increase in my energy levels within a few weeks of taking it. And without any of the tummy troubles I usually get with iron supplements! Highly recommend.
