Generally, mixing lower counts of probiotics works well, but not for an extended length of time as you can be obtaining much more of one type than you are the others. You would have to study the labels to see this imbalance, but as I said, for a month or so would be fine.
When you purchase your next probiotic, try to find one that contains Lactobacillus acidophilus DDS-1 instead of just regular Lactobacillus acidophilus. This is much more beneficial in the Candida treatment specifically. MegaFlora made by MegaFoods is one brand that contains this.
