Does Yakult Go Bad If Not Refrigerated?

Yakult, a probiotic beverage is excellent for the gut microbiome because it contains huge amounts of live, useful bacteria. It’s a great way to make sure your digestive system is functioning properly.

Children who drink Yakult every day have a 14% decrease in the incidence of diarrhoea. Yakult drink can help to boost immunity and keep the balance between good bacteria in the intestines!

But how should this drink be stored optimally? Yakult can be left out of the refrigerator for up to 4-8 hours without any issues.

At temperatures between 15°C-40°C, the Yakult microbes will begin to become active. Once they reach that point, they will slowly start to die as they operate out of nutrient content to stay alive.

However, you must consume the drink after you’ve opened the bottle. Bottles are aseptically packaged so they can be consumed without refrigeration.

If your doctor has advised you not to drink cold beverages, you can take Yakult out of the refrigerator and let it sit at room temperature for a few hours before drinking.

How to Keep Yakult Fresh?

The majority of Yakult containers have a 45-day shelf life after the production date. Probiotic drink enthusiasts may want to know how to store Yakult.

The ideal storage temperature for Yakult is between 5-10 °C. Yakult should not be left in a room atmosphere for over a few hours because doing so may harm the live bacteria.

Although brief periods are acceptable, the quality of Yakult suffers if left in the refrigerator for too long.

Yakult at Room Temperature

You can keep probiotics at room temperature but only for a few hours. So, don’t forget to put them in the fridge as quickly as you can.

The real-time bacteria used to make the probiotic drink is good for a healthy gut and can live in this environment. Yakult offers the same advantages when served at room temperature as when chilled.

It’s crucial to keep in mind that serving Yakult at room temperature increases the likelihood of spoilage. It is therefore best to drink the beverage soon after it has been opened.

You can allow Yakult to heat up a little at room temperature right before drinking it if you keep it in the refrigerator. Just don’t expose it to heat for a long time!

Yakult must always be kept in a temperature range below 4°C. The lactic acid bacteria in Yakult are susceptible to deterioration and even death at elevated heat.

Is It Ok to Freeze Yakult for Storage?

You can freeze Yakult, but it isn’t advised sometimes because the bacteria can become dormant and may be harmed by the cold. If Yakult is frozen, it is best to slowly defrost it and consume it in a week.

Long-term exposure to cold temperatures can reduce the effectiveness of bacteria. So, it isn’t good to keep Yakult containers in your freezer to increase their shelf life.

Yakult bottles frequently leak when placed in the freezer because they don’t have much room for expansion. This occurs because as the yogurt freezes, it expands and has nowhere else to go.

Because of these two factors, experts do not advise freezing Yakult; instead, it is much better to keep your containers in the refrigerator.

Does Unrefrigerated Yakult Go Bad?

Yakult probiotic is produced by mixing milk with a unique strain of bacteria, which converts lactose into lactic acid. This is what gives Yakult its distinctively tart flavour.

Since Yakult contains lactic acid bacteria, it is best to eat it as soon as it is taken out of the refrigerator.

If Not Refrigerated, Yakult Will Spoil

Due to the presence of live bacteria, you should keep probiotics to refrigerate. Yakult probiotics can become dangerous if the bacteria are polluted by other bacteria and if the beverage is not kept chilled.

Depending on the time of day, the acid environment can cause cells to die, which can reduce their effectiveness. Additionally, the enzyme from dead cells can make a product acrid.

Yakult has a longer shelf life when kept in a refrigerator with a temperature no higher than 10° C from the date of manufacture. Yakult will begin to spoil if not kept cool.

If kept chilled, Yakult will last for up to 2 weeks after being opened. It should be consumed within a week of opening because after that time the drink will continue to ferment and get sourer.

How Long Can Yakult Be Left Out of the Fridge?

Having a drink of Yakult stay out of the fridge for too long is one of the biggest risks. Yakult’s bacteria may begin to develop and proliferate if it isn’t kept in the fridge.

The bacteria can generate toxins that really can make you sick. This may also result in food poisoning. Yakult food poisoning symptoms include diarrhoea, nausea, and abdominal pain.

In extreme circumstances, it causes dehydration or even death. See a doctor right away if you believe you consumed Yakult which was unnecessarily left out of the refrigerator.

It’s crucial to keep Yakult cold at all times to avoid getting sick from it. However, more than two hours should pass before Yakult is removed from the refrigerator.

Yakult is a fantastic choice if you’re looking for a bifidobacteria dairy beverage that is both tasty and safe. Just ensure that you keep it cold to prevent any possible health risks.


Microorganisms in probiotics are living things that are healthy for your body when consumed. The most prevalent of these live microorganisms are bacteria found in a bottle of Yakult, which is beneficial.

There is no restriction on the number of bottles you can consume each day because Yakult is a functional food rather than a medication. The benefits can be obtained with at least one bottle per day.

If Yakult is not kept cold, its bacteria can produce toxins and can make you ill. After consuming the rotten product, you might encounter symptoms that will lead to seeking a medical emergency.

So, don’t forget to keep your Yakult cold. It is best to store it in the refrigerator to ensure that it remains tasty and fresh.
