I’m currently trying this one as recommended by Dr. Carolyn Dean as part of her Yeast Reset Protocol. You can get a bottle of 90 for $69, which isn’t bad when you only need 1-2 per day. There is definitely a difference in type of probiotic and soil based organisms aren’t in most of the products on the shelf, except some in Garden of Life Primal Defense. You’ll find lactobacillus in fermented foods and you might be right on that you can’t beat fermented foods for that type, but SBOs won’t be covered and some people just don’t respond to what’s in most.
So far, I’ve noticed a couple days of feeling noticeably better, even with some horrible sleep. I’m doing this because I have a couple symptoms that fit Dr. Dean’s questionnaire - I predictably feel bad on rainy and overcast days, I’m extremely sensitive to alcohol and I have rash that won’t go away and I often have sleep issues. I’ve eaten keto for over 2 years now and these issues still haven’t gotten better.
Anyway, hope that helps. I can follow up when I’ve been taking it longer and know if it’s made a difference.
