Hi everyone - new member here. I've joined in some desperation to help my elderly Mum whose IBS-D is escalating with great detriment to her quality of life. She is probiotic-naive and has managed her IBS to date by limiting her diet and with judicious use of loperamide for flares, that's it. She has had a number of colonoscopies in recent years, had antibiotics a year ago for whooping cough, and takes lansoprazole among a number of other medications; so she has several risk factors for dysbiosis.
Based on my research so far the probiotic products which seem most likely to be efficacious (ie contain Lactobacillus and Bifidobacterium strains) are Visbiome GI Care (112 billion CFU/capsule) and Seed DS-01 daily synbiotic (37 billion AFU), both refrigerated products. The daily dose of strains for each of these seems quite high though and am a bit concerned about worsening her symptoms and putting her off before she can complete an initial 4-week trial. But I could be overthinking it.
So my questions are: 1) do you have any experience with these products and can you recommend them, 2) are these products appropriate for the elderly or should I be looking at lower-potency products - if so which ones, 3) do you have any other comments or recommendations based on the above.
Thank you so much for any advice you can give.
