My main problem was irritable bowel. I was down to eating next to nothing and still getting diarrhea, pain and discomfort throughout my abdominal area and swelling. I took threelac and oxygen elements max and to be fair I improved on those by themselves, but wasn't cured. I phoned the Finchley clinic for further advice and Mark Lester recommended me to take Marshmallow Formula (I took 1 twice a day) and MSM Max (I took 1 per day) which Mark said often helps with food allergies, and leaky gut etc. Within a few days of starting these products the diarrhea stopped and I found I could start eating foods I previously couldn't tolerate. I have increased energy, improved appetite (it's been years since I experienced hunger) and no longer feel ill. It's been amazing! The only thing is I can't tell whether is the main thing that's working because I am taking MSM and the Marshmallow formula at the same time.
My 9 year old daughter has been taking Marshmallow formula for frequent symptoms of nausea and food intolerances. I put her on 1 tablet twice per day of Marshmallow formula and a tablet of MSM She has been much better since taking these products.
