NOW® Gr8-Dophilus gets its name from the fact that it contains 8 species of beneficial bacteria, making it much more powerful and effective than an acidophilus, bifidus or acidophilus/bifidus combination. NOW has gotten all of the product details right with Gr8-Dophilus; enteric-coated capsule to protect the bacteria from harsh stomach acids, shelf-stable packaging that requires no refrigeration and even pre-biotic FOS saccharides to feed and accelerate the growth of probiotic bacteria. Use NOW Gr8-Dophilus to help recover from illness or to help maintain your current good health; probiotics are among the safest supplements with virtually no toxicity.
