Never taken it, but read their website and it looks rather interesting.
I noticed it has only 8 strains of probiotics though, and no yeasts, but those 8 stains are concentrated in extremely high doses.
Vsl#3 can be bought "over the counter" without a prescription, while Vsl#3-DS requires a prescription? Apparently the only difference between the 2 is that the DS version is "double strength." So wouldn't taking 2 pills of the regular strength be exactly the same as the DS version?
Just seems odd to me, unless the purpose of making a prescription version is for insurance coverage--to lower the cost.
The manufacturer claims each vsl#3 packet/tablet contains 450 billion live beneficial bacteria, which is 10-100 times the bacteria of most other tablets, which seems pretty decent.
A cup of kefir on the other hand, can contain as many as 4-5 trillion live bacteria, along with a wide variety of beneficial yeasts, and far more varieties of bacterial strains.

But then again, I have no idea whether all those additional bacterial strains and yeasts are necessarily of any greater benefit to Crohn's/IBS/Colitis, or which survives stomach acids best to make colonize the digestive system. Kefir's probably cheaper though, providing if you ferment your own.
Vsl#3 seems rather expensive for a probiotic, especially considering a pack of 30 costs $88, and the recommended dose is 2-8 per day.
If it works though,it's worth it. Am very interested in learning your results
