HIGH POTENCY To receive 70 Billion CFU per day you would need to take 14 capsules or pearls of most probiotics that contain only 5 CFU per capsule. When choosing a probiotic supplement, strength really does matter! More CFU means more good bacteria. The number of strains also matters - Island's Miracle ULTRA-70 contains 15 beneficial strains. 20 TIMES MORE EFFECTIVE THAN OTHER PROBIOTICS. Even if the capsule has many CFUs, the main challenge for the Probiotics is to be able to get through the stomach acids. Most die in the process and never make it to the small intestine. This is why many of the Probiotics on the market are very inefficient. Our Probiotics feature DRCaps that increases the survivability 20x on average compared to other Probiotics. DRCaps ensures the beneficial probiotics are not destroyed by stomach acids so they can safely reach the small intestine where they are needed most. SURVIVE STOMACH ACIDS AND GET WHERE THEY ARE NEEDED - Our Best Probiotic features the most innovative delivery system (stomach acid protection) that ensures strains can survive the stomach acids and reach deep into the small intestine alive. Our best rated probiotics will even reach your large intestine, making it more than 20 times more effective than other top probiotics. POTENCY UNTIL EXPIRATION DATE. With our supplement you will receive at least 70 billion CFU all the way to the expiration date. If you buy a probiotic supplement that doesn’t ensure potency until expiration date, all the strains could be dead by the time they reach the market. With Islands Miracle Probiotics, you can be certain that the strains will be alive and ready to work until the expiration date. SHELF STABLE - NO REFRIGERATION REQUIRED. Our probiotics supplements are shelf stable and don't require refrigeration. However, if you don't live in a cool, dry place or keep your home below 78 degrees, it is best to store your bottle in the fridge, when and if you can.
