Typically L. bulgaricus bacteria are 2-3 times bigger than acidophilus bacteria so direct, numerically quantitive comparisons are not appropriate. Different Lactobacilli strains have different characteristics and very different survival/reproductive capabilities when in the hostile environment of the human GI system.

The Plantbiotic product is a patented probiotic blend of natural ingredient containing Lactobacillus bulgaricus, Lac. Acidofilus and Streptococcus thermophilus. This patented blend also includes Inulin, which has been included to aid in the survival and reproduction of these friendly bacterial when they are reactivated in the gastrointestinal system.
