A really good probiotic I use which even claims it aids vaginal health, high cholesterol and lactose intolerance is the Primadophilus Reuteri made by Natures Way, the only downfall to this probiotic is it must be kept inthe fridge, so look for it in the stores fridge. However, for me it works great I don't even have to take lactaid pills anymore and my cholesterol levels are now normal instead of too high...In Canada I pay 28.00 for a bottle of 90 caps and only one/day is needed (not like the many kinds where you have to take 4/day) so 28.00 lasts me 3 months.
Good luck and let me know if you get this particular probiotic and how things go.
Just bought it today. Will let you know how it works out.
