Amazing stuff. Even works for SOD for me,

My better half has used this successfully to treat severe IBS.
When I later developed SIBO and Sphincter of Oddi disfunction I found it exceptionally helpful in combination with evening primrose oil for bile flow. I’ve been able to come off almost all treatment for SOD. Amazing stuff. Would highly recommend trying it if you have IBS or biliary / sphincter problems.

I suffer IBS and always looking for new products to help. Only took for 2 days when the terrible stomach pains and trips to the toilet started. 2 days without taking and I’m still suffering. I know things take time to work but it’s hard to continue when you feel awful

Holidat Gut Blues OVER!

For years every time I go on holiday abroad I suffer from severe bloating, loss of appetite, sickness and indigestion. I put it down to the change in water and food. So holidays are usually as much of a trial by my gut than a relaxing experience. I have just returned from a week in Greece where I took Ferrocalm for the 4 days before I went and religiously through the week and I felt amazing. The best holiday in years. Zero gut issues and I had the most relaxing time, not lying on a sunbed in pain with bloating, and feeling hungry but not being able to eat. It was amazing and I will definitely stick with Ferrocalm now, it will be life changing.

Great product

Fast delivery of the product, interesting and helpful regular emails, I have been taking this for 6 weeks now and have noticed quite an improvement. Thanks Ferrocalm I will be continuing to use this with the hope of further improvement.

So far so good

So far so good. I have definitely noticed a difference and in quite a short time. After around 9 or 10 days things started to feel a little different. I had less gas, which in turn meant less burning/stinging in my stomach. I am not 100% , yet , but certainly improving , slowly but surely. After nearly a month , 27 days to be precise , I am very hopeful and will continue with Ferrocalm to see how much better I get. I'll update in 3 months!

Still early days but after being recommended by a family member to try Ferrocalm after only using for a month my bowel habits have improved. Being a long distance runner I suffered terribly with shall we say an urgency to use the toilet on my runs. This has improved considerably so fingers crossed it continues.

Has not met the expectations linked to its acclaim

It has been a year for me since I started to take Ferrocalm. I replaced my previous probiotic with this after reading its claims on LinkedIn. Having suffered with IBS for many years and acute stomach issues combined with weight loss in 2021, I had managed to find a supplement which assisted some of these problems, but was best taken alongside a probiotic. I cannot say that this probiotic has achieved anything different for me than the previous. It did not/could not calm my gut, when in pain; it could not help with constipation as the Mag 07 does and it certainly did not temper the issues after having gluten or lactose/dairy. So, as I now look for my next supply of probiotic, I wonder if it is worth my while buying another year's supply or I go back to my previous probiotic?

Game changer

Ive been desperate to find a way of settling my IBD, Ive tried fodmap and various diets but nothing helped. I've been taking Ferrocalm for a month now and I've noticed it's already improving. I've gone from awful bouts of diarrhoea and cramps that lasted hours a few times a week to nothing apart from one episode which was way less dramatic than normal and I was able to get on with my day quickly. Literally the only difference is the Ferrocalm. Hoping this continues as so far its been a game changer.

Was told about this cause I suffer from IBS. Have been taking it for a month. Have had only one flare up in that time but without the terrible pains I got before taking it. It appears to be working so will continue to take this and hopefully things will get even better

What a difference in my health …

What a difference in my health the last few weeks. Have tried literally hundreds of different things to help my IBS & Ferroclam is by far the best. Less bloating & more frequent toilet visits. Will be keeping up my subscription 🥰

I started taking Ferrocalm three months…

I started taking Ferrocalm three months ago. At that time I couldn’t tolerate any wheat and wouldn’t even dare to go out for a meal in public due to the severity of my IBS-D. As time has gone on I’m now able to tolerate a small amount of coffee, dairy and gluten/wheat. Don’t get me wrong I still have some off days but nowhere near how horrendous it used to be. Ferrocalm really is changing my life for the better plus they arrive super quick and whoever is behind it is an absolute genius! Also I’ve come off the amyltriptaline that was prescribed to me over the past year and I only take Ferrocalm now. GAME CHANGER!

So far…so good

So far…so good. I’ve been taking Ferrocalm for just under a month and I am beginning to believe that it is helping me. Of course it’s still early days, but my bloating and IBS has certainly given me far less problem this last month and I will definitely continue to take it. The company supplying it have been most helpful and efficient, so no complaints there…a good experience so far.
