5 Reasons Women With Low Ferritin Are Switching to Kerava for Hair Shedding and Low Energy
3 STORAGE COFACTORS

1. It Targets a Cause of Hair Shedding That Most Doctors Never Test For
Your hair follicles rely on ferritin, the iron your body keeps in storage, to grow. When ferritin drops too low, your body sends iron to vital organs first, and hair growth is one of the first things it cuts back.
Kerava is built to help raise your ferritin toward 70 or more, the level Core Balance Nutrition points to for healthy hair growth.
Core Balance Nutrition says shedding typically slows between weeks 6 and 8, baby hairs can appear around week 8, and new growth often shows around the start of month three. The thin spots along your part are where most women look first.
2. Their Energy Comes Back
Low-ferritin exhaustion is not ordinary tiredness. Your arms and legs feel heavy. Climbing stairs leaves you out of breath. Getting through the afternoon takes everything you have.
If you have started to think you are lazy, you are not. Your iron stores may simply be low.
Core Balance Nutrition says most women notice more energy within 3 to 4 weeks, with fewer afternoon crashes and clearer thinking by week 4. Feeling like yourself again is the goal.
3. It Is Gentle on Their Stomach
You know what low-cost iron can do to your stomach: constipation, nausea, cramping.
Kerava uses iron bisglycinate, a chelated form of iron that Core Balance Nutrition says is gentle on your stomach. Take 2 capsules a day on an empty stomach.
Ferrous sulfate absorbs poorly, and Core Balance Nutrition says the rest can sit in your gut and cause problems. Core Balance Nutrition says iron bisglycinate absorbs up to 4 times better, with no constipation, nausea or bloating for most women.
4. It Is Built to Raise Ferritin in Weeks, Not Years
Picture taking iron every day for months, then seeing almost no change on your lab report.
Core Balance Nutrition recommends 8 to 12 weeks before you judge your results, and suggests retesting your ferritin with your doctor at week 12.
The reason: Kerava includes the cofactors your body uses to absorb and store iron, including vitamin C, B6, B12, folate, copper, lactoferrin and L-lysine, so more of the iron you take can end up stored as ferritin.

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!

If I could give it 10 stars I would. I normally don't give reviews, even if I like the products so this clearly has impressed me with the results. This product does EVERYTHING listed. I have so much more energy, my hair is fuller with less shedding, and so much more color in my face. Whoever created Kerava, may you live long and prosper. 😂 I will forever be a customer.
