Probiotic supplement recommendation?

I tried a few but Keybiotics contains a really good range of strains and ultimately had the biggest positive impact for me personally. Buying one or two is expensive but unlike VSL3, there's the option to bulk buy which makes them really affordable.

VSL#3 has many more billions probiotics in each one (sachets not pills) than any other probiotic and (as stated) it is the only probiotic with research studies showing that it works for UC. I've always ordered mine directly from the company because I know it has not been sitting in a super-hot warehouse and possibly killing the live probiotics.

VSL#3 always arrives with ice packs in a styrofoam cooler.
That said however you need to try VSL#3 out and see if you gut accepts those particular probiotics. Every gut is different. Start with half a sachet for 2 to 3 days and then go up to a full one. Those in a flare use the DS version, which means double strength. This is available as an RX but many insurance companies will not pay for it. The work-around is to pay for the regular VSL#3 and take a double dose until your gut settles down.

I no longer take VSL#3 because I'm in remission. I still take a daily probiotic and have switched back and forth from Reuterii pearls and L. plantarum. These are much less powerful than VSL#3.

Re: yogurt. The chances of the Yogourmet probiotics reaching your gut alive are not proven but it won't hurt to keep taking it since human populations who consume live probiotic yogurt are healthy long-lived. It just doesn't have the billions of probiotics that VSL#3 has.

Good luck.

The capsules have 112.5 billion CFU's, which is still more than just about any probiotic. I personally prefer them to the satchets.
