I was doing more research on threelac one of the main ingredients is listed here:
http://www.cfsan.fda.gov/~mow/chap21.html
It is actually listed by the FDA as being pathogenic. Listen to some of these things about it.
1. Name of the Organism:
Streptococcus spp. The genus Streptococcus is comprised of Gram-positive, microaerophilic cocci (round), which are not motile and occur in chains or pairs. The genus is defined by a combination of antigenic, hemolytic, and physiological characteristics into Groups A, B, C, D, F, and G. Groups A and D can be transmitted to humans via food.
Group A: one species with 40 antigenic types (S. pyogenes).
Group D: five species (S. faecalis, S. faecium, S. durans, S. avium, and S. bovis).
2. Nature of Acute Disease: Group D: May produce a clinical syndrome similar to staphylococcal intoxication.
3. Nature of Disease: Group D: Diarrhea, abdominal cramps, nausea, vomiting, fever, chills, dizziness in 2-36 hours. Following ingestion of suspect food, the infectious dose is probably high (greater than 107 organisms).
5. Associated Foods: Group D: Food sources include sausage, evaporated milk, cheese, meat croquettes, meat pie, pudding, raw milk, and pasteurized milk. Entrance into the food chain is due to underprocessing and/or poor and unsanitary food preparation.
I'm no expert and don't know everything but it would seem as though that strain of bacteria may not be the best choice.
the main ingredient: Lactobacillus Sporogenes is recognized by others as being good for candida. It is also included in floral balance.
The last main ingredient: Bacillus Subtills also seems to be known for help in candida but only for animals. This is the only reference I could find to it besides it's use in threelac.

Again I'm no expert here but just doing my research.
