I keep answering this on seperate posts so I decided to make this to try and let folks know that VSL#3 is not expensive...in fact, from the all the probiotics I've looked at (and it's far from all inclusive), VSL#3 is the best value for your money...here's why I say that:
VSL#3 contains 450 billion bacteria per packet and each packet costs (at most) $3. So it costs $0.07 for 10 billion bacteria in packet form.
Culturelle (sold at Target--I just picked this as an example because it has a lot of bacteria compared to most) contains 10 billion bacteria per capsule; 30 capsules cost $18.59. So it costs $0.62 for 10 billion Culturelle bacteria in pill form.
VSL#3 pills (to compare pills to pills) have 225 billion bacteria per pill. 60 pills cost $48.50. So it costs $0.36 for 10 billion of VSL#3 bacteria in pill form.
The thing I like best about VSL#3 is the bacteria are freeze dried, come from 8 strains, and they are shipped and stored cold to assure the bacteria remain alive.
I get VSL#3DS mail order. With my copay I end up paying $0.008 for 10 billion VSL bacteria (packets)
There's no need to buy pills. If you want to go the least expensive way and don't need 450 billion bacteria per dose then buy the VSL#3 packets and split the powder up in to different doses.
