No other product on the market delivers more live organisms into the digestive system than Ultimate Probiotic 4-Billion. Nature's Secret has once again set a new standard in digestive care with their new Ultimate Probiotic 4-Billion. This powerful shelf-stable blend contains 19 crucial strains of friendly bacteria. But the key breakthrough is in its patented delivery system, which gets morelive probiotic bacteria into the upper GI tract than any other product on the market. Probiotics on store shelves today fail to disclose that up to 95% of their organisms die when they are burned by the harsh acids in our stomach. For example, a product that claims to have 30 billion live cells per capsule, may actually only deliver 1.5 billion live cells into the intestines where they're needed. Each high tech tablet of Ultimate Probiotic 4-Billion forms a patented gel barrier around the capsule as soon as it comes in contact with the fluids in your stomach. This one millimeter thick protective gel barrier ensures that the delicate probiotic organisms inside are safely delivered into the low acid environment of your upper intestines. The result? Better digestion, enhanced energy and immune support. No other product on the market delivers more live organisms into the digestive system than Ultimate Probiotic 4-Billion.
