Even though the HMF neuro has a low count, I feel it is very effective for what it is. You can also purchase the powder which you could potentially use to increase the potency or cfu amount you ingest.
If I were to go back to the renew life stuff, I would look at the high count probiotics they have such as the 80, 100, or 150 billion cfu stuff. This is one thing that seperates them from the other brands is the high count products. Another plus is that their products are stable without refrigeration if you travel.
Dvjorge mentioned a few other strains earlier in the week that sound effective as well. I might try those in time.
