YAKULT and yogurt are both fermented dairy products made from milk fermented with live bacteria. YAKULT is unique because it is made using Lactobacillus casei Shirota strain with live bacteria, not the strain of bacteria used in yogurts.
This strain of beneficial bacteria reach intestines alive, which is scientifically proven. YAKULT has been produced for the sole purpose of maintaining a balance of beneficial bacteria in the digestive system.
Yogurt is not a substitute for YAKULT and vice versa. They complement each other as part of a well-balance diet.
