Understanding the Core: The Unique Lacticaseibacillus paracasei Shirota (LcS) Strain
All Yakult varieties share a key component: the exclusive Lacticaseibacillus paracasei Shirota (LcS) strain. Developed by Dr. Minoru Shirota, this probiotic is scientifically proven to survive digestion and reach the intestines. It contributes to balancing gut microbiota, reducing harmful bacteria, and supporting digestive and immune health across all Yakult products.
Key Differences Between Yakult Varieties
While the core probiotic is the same, Yakult products differ in sugar and nutritional content to suit various preferences.
Yakult Original (Red Cap)
This is the classic fermented milk drink.
- Sugar and Calories: Higher in sugar and calories; a 2.7-ounce bottle in the US contains 50 calories and 10 grams of sugar. Ingredients include water, sugar, nonfat milk, glucose, natural flavors, and the LcS strain.
- Taste Profile: Known for its sweet and tangy citrus flavor.
- Who is it for? Those who prefer the traditional taste and don't need to restrict sugar or calorie intake.
Yakult Light or Balance (Blue Cap)
This version offers probiotic benefits with reduced sugar and calories.
- Sugar and Calories: Contains less sugar and fewer calories; in the US, it has 25 calories and 3 grams of sugar, sweetened with stevia extract and sugar. Sugar reduction varies by region.
- Added Nutrients: Often includes added vitamins D and E in some regions, which have antioxidant and immune benefits.
- Taste Profile: Less sweet than the Original but maintains the tangy citrus flavor.
- Who is it for? Individuals managing weight, sugar intake (including diabetics with doctor consultation), or those wanting extra vitamins.
Yakult Plus (Peach or Green Cap)
Available in certain markets, this variant adds fiber and other nutrients.
- Sugar and Calories: Lower in sugar and calories, similar to the Light version.
- Added Nutrients: Contains added dietary fiber to support gut health and feed beneficial bacteria. Also includes Vitamin C.
- Who is it for? Those seeking enhanced digestive benefits through added fiber and vitamins, particularly for bowel regularity.
Other Regional Variants (e.g., Ace Light, Gold)
Regional availability includes other Yakult products. For example, in Singapore, Yakult Ace Light has a higher concentration of LcS (30 billion per bottle) with fewer calories. Yakult Gold in Singapore also offers more probiotics with less sugar. These variants address specific market needs, like a higher probiotic dose.
