Three situations, the same fatigue
Pick the one that sounds like you, and we'll explain what changes for you.
"I took iron for months and felt nothing, except in my stomach. So I went looking for why."
- After giving birth, I was exhausted. My iron was low.
- The prescribed iron didn't boost my energy, and my gut couldn't take it.
- So, as a biologist, I created the iron I couldn't find.

Designed to maximise iron absorption
Ferro Fatigue REDUX combines microbiotic strains with iron bisglycinate, folic acid, vitamin C and calcium.
What if your fatigue came down to iron?
Iron carries oxygen throughout your body. When your stores run low, your energy follows. It's one of the most overlooked causes when you feel drained.
And for your first iron, you may as well start with a formula designed to be well absorbed and gentle on your gut, rather than discovering the discomfort of classic iron.
Blood iron varies from day to day. Ferritin reflects your iron stores. It's the value to ask your doctor about if you feel tired.
If in doubt or if you're on medication, talk to your doctor or pharmacist.
It's not you. It's iron that hasn't evolved.
Iron sulphate, then bisglycinate: for decades, innovation has stopped at the form of iron. As a result, many women go through the same thing:
- No real difference in energy
- Constipation, bloating, nausea
- Blood test results that barely move
Ferro Fatigue REDUX tackles the two real causes: the timing of your intake and what happens in your gut.
Plenty of iron on your plate, but does it get through?
Lentils, spinach, tofu: plant foods contain iron, but in a form (non-heme iron) that the body absorbs much less easily than the iron from meat. That's why vegetarians and vegans often need to pay extra attention to their iron.
So when you supplement, absorption is everything. Ferro Fatigue REDUX is 100% suitable for vegetarians and vegans, and built entirely around getting more iron through.
- Pair iron-rich foods with vitamin C (citrus, peppers, kiwi)
- Keep tea and coffee away from iron-rich meals
- Check your ferritin regularly with your doctor
3 innovations, one simple routine
The right form of iron, the right rhythm and the right strains, spread over 2 capsules that you alternate: one a day.
Ferrochel®
A patented iron bisglycinate, more bioavailable than classic iron salts and associated with less digestive discomfort, backed by over 100 studies[6,7].
Every other day
An iron capsule one day, a microbiotic capsule the next. Hepcidin gets time to come back down before the next dose of iron[1,2].
"Transforming" strains
L. fermentum IQB 2411 produces lactic acid, which lowers pH and helps make iron soluble, so it's easier to absorb[8].
Light capsule: strains
Iron better absorbed
Day 1, 3, 5...Dark capsule: iron
- Ferrochel® iron bisglycinate
- Vitamin C, which increases iron absorption2
- Folic acid
- Nettle leaf extract
Day 2, 4, 6...Light capsule: microbiota
- L. rhamnosus IQB 2911 and L. fermentum IQB 2411
- 3 billion CFU
- Calcium, which contributes to the normal function of digestive enzymes4
Iron, 100% science
Tested with a university team
In the lab, we compared Ferro Fatigue REDUX with iron sulphate and with bisglycinate alone, together with Dr Zorita Diaconeasa's team (University of Cluj-Napoca). The combination of iron and microbiotic strains came out clearly ahead.
Pairing the best form of iron with strains chosen to boost its absorption made a clear difference in our study.Dr Zorita Diaconeasa, lead researcher of the study, University of Cluj-Napoca
Why unabsorbed iron upsets the gut
Part of the iron you swallow is never absorbed and ends up in the colon. There, it favours some bacteria over others (known as dysbiosis) and generates free radicals and oxidative stress that weaken the gut lining[4]. This is one explanation for the digestive discomfort often reported with classic iron[5].
Hence our approach: first make sure the iron is better absorbed, then support the gut with selected strains.
Not all forms of iron are equal
Ferrochel® iron bisglycinate is a "chelated" iron: bound to an amino acid, glycine, which protects it in the stomach. It is more bioavailable than iron salts such as sulphate[6] and has been associated with fewer digestive issues[7]. Over 100 studies have been carried out on this form.
Hepcidin, the hormone that decides whether your iron gets through
Every dose of iron raises hepcidin, a hormone produced by the liver. For around 24 hours, it "closes the door" on the absorption of the next dose[1-3].
Published studies show that taking iron every other day lets you absorb a greater share of it, up to 40% more than daily intake[1,2]. Ferro Fatigue REDUX builds this rhythm in from the start: the iron-free day becomes a microbiota day.
How microbiotic strains help iron
Iron is absorbed in the gut in its "ferrous" form (Fe2+), through a transporter called DMT1. L. fermentum IQB 2411 produces lactic acid, which lowers local pH and creates a better environment for absorption, and produces a molecule that helps turn insoluble iron into soluble iron[8].
Our lab study
In vitro study carried out with the University of Cluj-Napoca (Romania), comparing iron absorption from Ferro Fatigue REDUX with iron sulphate and with iron bisglycinate alone. Results: +85% and +54% absorption. This is a laboratory model, not a clinical study in humans[9].
What really changes
Three approaches to iron, side by side.
| Classic iron (sulphate) | Bisglycinate alone | Ferro Fatigue REDUX | |
|---|---|---|---|
| Form of iron | Iron salt | Chelated | Chelated Ferrochel® |
| Rhythm that respects hepcidin | ✕ | ✕ | ✓ every other day |
| Microbiotic strains | ✕ | ✕ | ✓ 2 strains, 3 bn CFU |
| Vitamin C + folic acid | Variable | Variable | ✓ |
| Absorption tested by the brand (in vitro) | ✕ | ✕ | ✓ +85% vs sulphate |
Why 4 months?
Rebuilding iron stores takes time: red blood cells renew roughly every 120 days. Four months covers one full cycle.
Get your ferritin tested with your doctor. That's your starting point.
The rhythm settles in: dark capsule one day, light capsule the next, at breakfast.
Iron contributes to the reduction of tiredness and fatigue1. Keep going, without skipping days.
A full red blood cell cycle. The right time for a new blood test to check your stores.
They rethought their iron
"I had been tired and constantly exhausted for a long time. After just 2 weeks I noticed real improvements: more energy, and not a single side effect, unlike the iron pills my doctor prescribed. Not the cheapest option, but worth the investment."
"I've tried several iron products and always had stomach and gut problems, so I stopped taking them. With this one, no issues at all. I had my blood tested again and my iron values had clearly gone up!"
"First time I took an iron supplement. After 2-3 weeks I could really feel a boost of energy. I'm taking it as described, one day iron, the next day microbiotics, and have no problems at all."
"During and after my period I always felt so tired. I now take it from the start of my period until a few days after, and I really feel the difference: much less tired. And none of the nasty stomach and gut side effects I had with other products. A bit pricier, but really worth it."
"This is the second time I've reordered. My stomach and gut tolerate this iron much better than the usual preparations prescribed by the doctor. I can only recommend it!"
"As a long-time vegan I've tested several iron supplements, but they often upset my stomach. After 3 weeks I feel more energetic and have no stomach or digestive issues. I've already reordered."
"Felt much more energy after just 1 week! And no constipation, which I always had with other iron supplements. Top product!"
"I often have low iron and need to top up regularly. Other products were hard on my stomach and gut, but not anymore! I'm a fan and will keep using it."
"I donate blood regularly and my doctor advises iron afterwards. Unlike most other iron supplements, this one causes no stomach pain and no nausea. After a week I clearly had more energy."
Personal experiences. Results may vary from person to person.
Your questions
How do I take Ferro Fatigue REDUX?
One capsule a day, ideally at breakfast, alternating: one day a dark capsule (iron), the next day a light capsule (microbiotic strains). One box of 30 capsules lasts one month.
Why every other day?
Because after each dose of iron, hepcidin slows down the absorption of the next one for around 24 hours. Leaving a day between doses lets you absorb a greater share of the iron[1,2]. On iron-free days, your microbiotic strains take over.
Why 4 months?
Red blood cells live for around 120 days. A 4-month programme covers one full renewal cycle, which is why we recommend it to rebuild your stores, followed by a blood test with your doctor.
Why is calcium in the light capsule?
Calcium can interfere with iron absorption when taken at the same time. By placing it in the microbiota-day capsule, we avoid this competition. Calcium contributes to the normal function of digestive enzymes4.
I already take prescribed iron. Can I switch to Ferro Fatigue REDUX?
Talk to your doctor or pharmacist before changing a prescribed treatment. Don't combine several iron supplements without medical advice.
Should I get a blood test first?
It's recommended: a ferritin test shows the state of your iron stores. Re-testing after 4 months lets you track progress with your doctor.
Can I take it during pregnancy or breastfeeding?
Iron needs increase during pregnancy. Ferro Fatigue REDUX can be taken, but always ask your doctor, midwife or pharmacist first, both during pregnancy and while breastfeeding.
Is it suitable for vegetarians and vegans?
Yes. Ferro Fatigue REDUX is suitable for vegetarians and vegans, with plant-based capsules. It's actually a great fit: iron from plants is absorbed less easily than iron from meat, so absorption matters even more.
How should I store it?
At room temperature, in a dry place. No need to refrigerate, even for the microbiotic strains. Shelf life: 24 months.
