The Only Product That Worked!
I have to say that this probiotic has worked great! I had consumed too many antimicrobial teas, plus echinacea, grapefruit seed extract, etc., because I thought was coming down with something. I stripped my gut of what was probably ALL beneficial bacteria and cause a severe case of dysbiosis! I struggled with loose and watery stool for about three months, with nothing else, including Florastor, getting me back on track. After about two weeks, this product has me regular again, with a proper consistency. Since I had SIBO about six years ago, which makes my gut more susceptible to issues, I plan to continue with this product!

Hard to ascertain with items like this, but it appears to be fine; albeit rather expensive.

One of my MUST haves
I have used these for years and are my must haves! They don’t need to be refrigerated, which I love! They are a great value, compared to most probiotics. They keep me regular without over doing. I highly recommend these to everyone!

Dosage
I will be updating this every few months. Both my spouse and I have begun taking a Spore Probiotic. I have two brands we are using. I am on the Youtheory. My spouse is on Microbiome Labs MegaSporeBiotic. We are both within normal weight range with 10 lbs to lose each, to put us at Ideal weight within that same normal BMI. 1: One of us is SIBO gut challenged. I had been on PPI on and off, and finally became compliant, to the point that small intestine bacterial overgrowth occurred. What my doctor viewed as successful dosing, in turn served me up a horrid gut imbalance. That, in under a year of Compliance, so watch out if you are on PPI, the signs are bloating and often a flip flop between constipation and diarrhea. It only seems mild until it crosses the line to intolerable. 2: The other of us is pre-diabetic, cholesterol, early kidney challenged. There are studies that note that B Subtilis may influence glucose transporters to benefit those who have challenges, as well as other spores which Influence cholesterol positively. Spore probiotic have a long lifecycle and slowly colonize the GI tract. They have a span of 3-4 weeks, compared to the 4-7 days of traditional probiotics. A traditional probiotic has a low survival rate in arriving, thus, more billions upon billions are required in dosage. Thus the smaller dosage of Spore Probiotics which are 3 billion per capsule, is actually superior to the many more billions of the traditional probiotics. That said, smaller doses over time are the approach I am taking. There are so many studies and for a great reason, all the evidence is pointing to Spore Probiotics being beneficial. Spore probiotics, being hardier and able to survive the voyage through your gut, require a more watchful approach. As many manufactures of Spore Probiotics state, start out slow and work your way up to a larger dose. This makes perfect sense. That of course does not factor in age related issues, health challenges, SIBO, IBS etc. The last thing you want is to experience something (nausea, diarrhea, fatigue, un-wellness) if indeed a different approach could have been taken. So while die-off symptoms can be severe when they hit, working up slowly in dose can negate much of that hardship! That said, I forgot that rule of thumb and did the first week starting out a touch quicker than I should have, before switching over to an every other day regimen halfway through the week. What hit was a touch of not feeling quite well, and taking a break from activities to recover. The other person I simply started at 1 capsule, every third day, as I did not want that person to experience any challenge. That person in turn, did well with the first week. Thus I kept to an every third day schedule for the first two weeks, prior to graduating to every other day for the next two weeks. At this dosage, the first month will not present the outcome of regular use, but it will serve to ease us into this new probiotic without much of the side effects of die off. I will update this in a couple of months.
