Question about probiotics

I've been taking Culturelle for a while now. I take one a day. Should I be increasing it to 2 a day or is that too much? Can you take too much probiotics?

I read a lot of posts about VSL#3. Is that a probiotic? If so, what's the difference between that and Culturelle?

My son takes 2 Align when he's having looser stools.... it helps.

Culturelle claims to have 10 billion per dose - that's pretty good! A lot of the ones we see on the shelves have less.
Culturelle's big thing is the lactobacteria.... I've had two GIs tell me that we with UC need more stains, especially bifido bacterium.

VSL#3 is a probiotic with a number of different strains. It has 450 billion per dose, VSL#3DS (Double Strength) has 900 billion per dose. In the last few weeks I've been fighting off some inflammation and I've been taking 4 doses of VSL#3DS a day as an experiment. (Right.... 3,600 billion.) So far so good. I have had an increase in gas the past week, and I can't know if that's the flare of the VSL! LOL! So I'll tinker with the dose and report back in.

(The only way I can afford to take all this is that the DS is prescription, and my insurance kicks in on the cost.)

There are a lot of other probiotics out there..... Ultimate Flora, Primadophilus... you can see them in many of our signatures.

FYI Ive read it helps to take our probiotics on an empty stomach.
