Is Yakult Good for You?

Yakult is made by fermenting milk which contains 6.5 billion good bacteria–Lactobacillus casei shirota, which reach the gut alive, and hence is referred to as a probiotic drink. These bacteria were discovered by Dr. Minoru Sirota. The word Yakult comes from the word “jahurto” which means yogurt in Esperanto.

Is Yakult Good for You?

Yes, it is good for health. It does contain high amount of sugar and artificial flavorings and sweeteners, but the benefits outweigh the presence of these additives. Besides the probiotic organisms, the ingredients in Yakult are water, skimmed milk powder and sugar. Yakult is available in 2 types:

  • Yakult Regular–containing 11 grams of sugar and 50 calories per bottle.
  • Yakult Light–containing 4 grams of sugar and 30 calories per bottle.

Regular Yakult has a serving size of 65 ml i.e. quantity per bottle and the sugar content is 18 grams per 100 grams. According to the UK Food Standards Agency, concentration of 15 grams per 100 grams is labelled as HIGH, hence the sugar concentration of Yakult is very high. For comparison, consider orange juice or Coca-Cola which contains around 10 g per 100 g of sugar, however, the serving size is 250 to 300ml. Although the sugar content is higher in Yakult, the serving is quite small.

Sucrose is used to sweeten regular Yakult, and Reb A–an extract of Stevia leaf, is used for sweetening Yakult Light. There is a lot of debate on the use of artificial sweeteners, as it is believed to be linked to cancer, according to some people. However, some people consider it to be safe.

Rebaudioside A is a sweetener derived from Stevia leaves and is considered as GRAS to be used in food and beverages, but not in meat and poultry. According to, it is 250-300 times sweeter than sucrose. This sweetener has zero calories, thus lowering the total caloric content of foods. They do not contribute to carbs or calories in the diet, thus do not cause any surge in blood glucose or insulin response. This helps diabetic people in eating a variety of foods and stick to healthy eating.

6.5 Billion Lactobacillus Casei Strain Shirota

The bacteria Lactobacillus casei Shirota was named after the Japanese microbiologist – Dr. Minoru Shirota, who was the first person to culture these bacteria. Yakult is considered to be the only probiotic drink to contain these bacteria. These bacteria have shown the following benefits:

  • Aid in digestion and improving bowel movement
  • Maintain balance of gut bacteria – good and bad
  • Help in reducing the toxins in the body
  • Reduce risk of infection by building the immune system

What Are Probiotics? How Do Drinks Like Yakult Benefit Us? 

Probiotics or good bacteria are lactic acid bacteria or bifidobacteria or group of bacteria. Lactic acid bacteria are naturally present in foods like yogurt and cheese which have been fermented. Probiotics or opposite of antibiotics are used for treatments. These bacteria are also referred to as gut friendly bacteria and they grow in the gut, where they would naturally be present. The normal bacteria in the body are responsible for breakdown of foods, absorption of nutrients and suppressing the bad bacteria in the gut. Bifidobacteria are used in treatment of disease, when the normal gut flora is killed. This can happen when antibiotics are prescribed, which can destroy good and bad bacteria, in the gut and urinary tract. When antibiotics are taken, probiotics should be taken along with it, so that the death of good bacteria is minimized.
