How does Kerava work?
Core Balance Nutrition says your body needs these nutrients to build and keep healthy ferritin stores:
- Iron bisglycinate, which Core Balance Nutrition says absorbs up to 4 times better than regular iron, without the usual stomach problems
- Vitamin C to help your body absorb more of the iron
- Vitamin B12, B6 and methylfolate to help your body turn iron into healthy red blood cells and energy
- Lactoferrin to help direct iron into your ferritin stores, so less of it passes straight through
- L-lysine to support absorption and help your body raise ferritin
- Zinc, copper and selenium to support hair, thyroid function and iron transport
When ferritin is low, you may notice heavy shedding, afternoon crashes, brittle nails, brain fog, and feeling cold all the time.
How long until I see a difference?
Most women notice more energy within 3 to 4 weeks, and shedding typically slows around weeks 6 to 8.
This is not an overnight change: you are refilling iron stores that may have taken years to run low. We recommend at least 8 to 12 weeks before you judge your results, and that is why Kerava has a 90-day guarantee.
Each bottle lasts 30 days. We recommend 90 days for best results, because hair follicles need steady ferritin to recover, and most women notice less shedding and new growth around the start of month three.
How do I take Kerava?
Take 2 capsules a day on an empty stomach, either 1 hour before breakfast or 2 hours after a meal. Your body absorbs iron best this way. Check with your doctor before use if you are pregnant, nursing, taking medication or have a medical condition.

I was exhausted all the time and losing hair rapidly. Doctors said I was 'fine' when my ferritin was only 18. After just 6 weeks on Kerava my ferritin is up to 74, my energy is back and I'm no longer seeing a clogged shower drain. This really works.

My doctor said my ferritin at 12 was 'normal.' Meanwhile my hair was falling out in clumps. 10 weeks on Kerava my ferritin hit 64 and the shedding stopped. Finally have baby hairs growing in again.

I tried biotin of course. Rosemary oil and shampoos. Nothing worked. Turns out I had an iron deficiency. Other iron supplements destroyed my stomach, but this one doesn't. Finally seeing hair regrowth and I'm now so much less tired during the day.

Diane M., 38, Phoenix AZ
My hair was falling out in clumps and I was so tired I could barely get through the day. I tried everything — biotin, Nutrafol, collagen, expensive shampoos. Spent probably $500. My hair kept falling out. Then I found out my ferritin was 14. Doctor said 'normal range' but hair needs it above 70 to grow. A friend introduced me to Kerava. 12 weeks in: shedding stopped around week 6. Baby hairs everywhere and my hair's actually getting thicker again. Energy is so much better. Checked my ferritin last week — 86.
Linda K., 44, Dallas TX
I was so exhausted I could barely function. Getting through the workday felt impossible. Brain fog so bad I'd forget words mid-sentence. My doctor tested my thyroid, my B12, my iron. 'Normal.' She never checked my ferritin. I had to ask for it myself. It was 18. I found Kerava through a Facebook group and figured I had nothing to lose. By week 3 my energy started coming back. By week 6 the brain fog lifted and I could actually think clearly again. I feel like myself for the first time in years and have a natural glow. I didn't realize how bad it was until it got better.
Sharon D., 38, Chicago IL
My hair was always thick. Then at 36 it started thinning fast. I was exhausted all the time too so my doctor checked my iron. 'Normal.' Said it was stress or genetics. I got my ferritin tested myself. It was 21 — technically 'normal' but I found out hair needs it above 70. No wonder nothing was working. Tried pharmacy iron pills but they destroyed my stomach. Kerava was my last try before booking an infusion. 11 weeks in: ferritin hit 73. Shedding stopped and I'm finally seeing thickness again. Wish I'd found this a year ago
How Does Ferritin Affect You?
Ferritin is the iron your body keeps in storage. When it drops, your body sends iron to vital organs first and cuts back everywhere else: your hair, your energy, your focus.
We point to a ferritin of 70 or more as the level your body needs to work at its best.
Kerava is built to help refill your ferritin stores over weeks, so your hair, energy and focus have what they need.
The iron built to be absorbed and stored.
Chelated iron plus the cofactors your body uses to store it.

What's Inside Kerava (and Why)
10 researched ingredients in every serving
Iron Bisglycinate (45 mg)
Absorbs up to 4 times better than regular iron. No constipation, no nausea, no bloating for most women, so your ferritin can rise without your stomach paying for it.
Lactoferrin (10 mg)
Helps carry iron into your ferritin stores and calms the inflammation that can block absorption. Without it, more iron can pass through without being stored.
Vitamin C (120 mg) + L-Lysine (400 mg)
L-lysine has been shown in research to raise ferritin in women whose numbers would not move on iron alone. Paired with buffered vitamin C to support absorption without upsetting your stomach.
Selenium (55 mcg)
Supports your thyroid, which affects how your body uses iron, grows hair and makes energy. Low ferritin and low thyroid can feel alike, and this helps support both.
Vitamin B12 (100 mcg) + B6 (10 mg) + Methylfolate (400 mcg)
Active forms that help turn stored iron into energy, red blood cells and clear thinking. Your body can use them right away, with no conversion step.
Copper (1 mg) + Zinc (10 mg)
Copper helps move iron from your gut into your blood. Zinc supports your hair follicles and helps your body use iron properly. Both are chelated, so they absorb well and do not compete with each other.

I have never written a review on any product I've ever bought online. That being said, this product is so amazing, I had to. I was losing my hair mid-shaft (basically had an unwanted mullet) for a year and a half, I stopped dying my hair, I see my hairdresser every 8 weeks, he hadn't cut my hair in over a year, because there wasn't much to cut. I was taking a bunch of other supplements hoping that would help, I tried castor oil, rosemary oil, and scalp massages, to no avail. I am in Perimenopause, my doctor told me it was normal for my age. I had a physical coming up and my doctor was out sick so I saw her PA, she was incredible, she tested my Ferratin, it was a 14! she said although that's technically in the "normal" range, she said women should ideally be 75 or higher. She prescribed me and iron supplement. I took it but did some research on my own. This product kept popping up, and the ingredients matched what my research was saying about the absorption of iron being much better when combined with other vitamins. In two months, my Ferratin more than doubled to 37! My hair almost back to where it has always been. I went to the hairdresser and he said " wow! I can actually cut and blow out your hair"! I am a customer for life now!! Thank you!!!

ok this is gonna be long but I need to help anyone else going through thisI lost about 40% of my hair in 6 weeks. it was absolutely traumatic. my hair used to be SO full and SO thick and suddenly I'm pulling out clumps in the shower and seeing my scalp in photos. I tried everything. biotin, rosemary oil, expensive shampoos, those scalp serums that cost like $100. hundreds of pounds. nothing.finally got my ferritin checked (not just iron — ferritin, theres a difference) and it was 14. FOURTEEN. my doctor said it was "in range" and I wanted to scream. I did my own research and apparently hair follicles need ferritin above 70 to actually grow properly???anyway I'd tried iron tablets before and they destroyed my stomach so I was nervous. but this one has a different type of iron (bisglycinate?). no stomach issues at all. literally none.3 months in. baby hairs everywhere. my hairdresser noticed before I even said anything. I'm not saying my hair is back to what it was but its GROWING again and I actually have hope nowif your hair is falling out and doctors keep saying you're fine — get your ferritin checked.

I'm a pharmacist so I don't buy into wellness nonsense. but I also know that "normal" lab ranges are not the same as "optimal." my ferritin was 16. technically "in range" (lab range starts at 12). my GP said I was fine. but I was exhausted, brain foggy, and my hair was thinning. I knew something was wrong. did my own research. turns out ferritin should be at LEAST 50-70 for energy and hair. the lab ranges are just "you won't die" ranges, not "you'll feel good" ranges. this supplement uses iron bisglycinate which is actually well-absorbed and doesn't cause the GI issues that ferrous sulfate does. 10 weeks in. ferritin up to 38 on my last test. energy genuinely better. hair shedding has slowed way down. still have a way to go but this is actually working.

ok I was VERY skeptical because I've wasted so much money on hair supplements that did nothing. like I have a drawer full of biotin bottles. but this is different because it's actually addressing WHY my hair was falling out, not just throwing random vitamins at it. been 10 weeks and the shedding has definitely slowed. seeing some baby hairs too. not a miracle but something is actually happening. buying another bottle!
