thanks,
@Hip ...and touche, re the marketing ploys
It's good to bear in mind that there can be marketing ploys, but on the other hand, with IBS, you do need to make observations about what may worsen your condition.
I think it is a bit irresponsible of manufacturers to be fabricating these marketing ploys when they don't appear to exist. It means when there is a genuine issue, nobody may listen. Like crying wolf.
If you put "supplements fillers" in Google, you find a whole raft or articles suggesting that various supplement binder, filler and flow agent ingredients are hazardous to health — but with little or no science to back it up.
The first time I heard someone say they got ill effects from carrageenan, I assumed it was just another marketing fabrication that they had been taken in by. But when I did a bit more reading into carrageenan, I learnt that it has potent effects on the body, so I realized that carrageenan may well affect sensitive people.
I have both ME/CFS and IBS-D myself, and I know I have to be careful about what I eat, as some things worsen my IBS (hot spices, or more than 1 unit of alcohol).
By the way, I am not sure which IBS you have, but for my IBS-D, I found the following very helpful.
Treatments for IBS-D:
Triphala herb 1500 mg
Imodium (loperamide) 2 mg
Chyawanprash (Indian herbal formula) 1 heaped teaspoon
Prebiotics (like inulin, 2 heaped teaspoon)
Sesame seed oil 1 tablespoon (15 ml)
Peppermint oil 200 mg
Turmeric level teaspoon
Manuka honey
The above IBS-D treatments are given in order of effectiveness, so triphala I found to be the best.
