Does MiO Go Bad

In this brief article, we will answer the question “does MiO go bad?” and will tell you what MiO is, what it contains, how to use it, and its possible downsides. 

Does MiO Go Bad?

Yes, MiO must be consumed within 30 days after opening. MiO does not require refrigeration, so it can easily be taken on the go.

Is It Safe to Drink Expired Flavored Water?

Product shelf life is notified to the consumer either as a “use-by” date or as a “best before” indicator. Use-by dates are employed for products where product safety may be compromised if the product is consumed later than the stated date. They will apply mostly to products where there is a significant microbiological risk factor. Therefore, it is not safe to drink expired flavored water (1).

If correctly stored at room temperature, unopened flavored water generally retains its original quality for at least nine months to a year. and remains safe to use even after this time has elapsed. 

However, if the flavored water develops a strange odor, or changes flavor or appearance, it must be discarded.

What is MiO?

MiO is a first-of-its-kind liquid water enhancer made by the Kraft Heinz food company. 

The word ‘mio’ means ‘mine’ in Spanish or Italian, and the company chose it as a symbol of power telling customers that they could make their water whatever they desired.

If you find it difficult to manage and maintain your daily water intake, a flavor enhancer such as MiO can help boost your daily water intake.

A single bottle of MiO contains 1.62 ounces (48 mL) but provides ten to 24 servings (depending on the product).

MiO is kosher and vegetarian-friendly and is available in various flavors featuring four product lines:

  • MiO Original
  • MiO Vitamins
  • MiO Electrolytes
  • MiO Energy

Flavors range from lemonade and black cherry in the Original line to açai berry and iced java in the Energy line.

What Is Inside MiO?

MiO Electrolytes, Vitamins, and Energy provide 10 percent of your daily vitamin B3, B6, and B12 requirements, and contain taurine, guarana, and ginseng, which have stimulanting and anti-stress effects (2). Guarana (Paullinia cupana) is a plant native to the central Amazon. It´s consume is associated to weight loss by increasing metabolism as well as suppressing appetite, energy boosting, improving fitness and sexual performance, and increasing cognitive performance and is used as antidepressant. Ginseng (Panax ginseng) is a highly valued herb, is widely distributed in Northeastern China, Korea, and Japan and has different constituents viz. ginsenosides, polysaccharides, peptides, polyacetylenic alcohols, and fatty acids, which have antineoplastic, anti-stress, and antioxidant properties. Taurine is a sulfur-containing amino acid, is found abundantly in retina, lungs, brain, muscles, and tissues of humans and in animal sources. Taurine is another important ingredient in caffeinated beverages, as it helps increase exercise capacity or physical performance (4).

Most flavors contain the artificial sweeteners sucralose and acesulfame potassium (Ace-K), whereas only two of the five flavors of the MiO Vitamins line are claimed to be naturally sweetened by stevia leaf extracts.

How To Use MiO?

MiO is classified as a low-calorie sport drink, developed towards improving athletic performance by recovering of electrolytes (salts naturally present in body used for regulating muscle contraction) and boosting by ingestion of stimulating compounds, such as guarana, ginseng and taurine, without the ingestion of sugar (2). Here are some important guidelines on how to use MiO:

  • A single serving of MiO is half a teaspoon (2 ml) in eight ounces (237 ml) of water.
  • MiO is a concentrated liquid and must never be drunk directly; always dilute it.
  • DO NOT mix MiO with alcohol; you can mix different flavors as per your liking.
  • Never leave MiO in the car. The excessive heat will compromise its quality. Also, MiO should not be frozen, although you can make MiO-flavored ice cubes.
  • The flavor enhancer features a spill-proof lid that clicks audibly when closed, which makes it very convenient to take on the go. 

How Many Calories Does MiO Have?

MiO is calorie-free, so enjoy drinking it without stressing over weight gain and consuming excess calories.

Can You Drink MiO Regularly?

MiO is safe to drink regularly, given your budget and flavor preferences. There have been no identified negative effects associated with common ingredients (B vitamins, ginseng, guarana, and taurine) in the amounts found within most energy drinks. Many side effects reported are likely due to the high levels of caffeine. Energy drinks are not recommended for children (2).

However, deciding if MiO is good for you and whether you should drink MiO daily depends on your overall health and diet.

Remember that you should always use MiO in the most natural way, mainly to boost your daily water intake.

Are There Any Potential Downsides To Drinking MiO?

There are a few downsides to drinking MiO concerning some of the ingredients used to manufacture it. 

The sweeteners used in MiO – Acesulfame K (Ace-K), sucralose, and stevia leaf extract – are generally recognized as safe by the Food and Drug Administration (FDA). However, due to their intensely sweet flavor and absence of calories, their health and environmental safety remain controversial. Acesulfame K is a crystalline potassium salt, 200-times sweeter than sucrose, from sucralose, only 11 to 27% is absorbed, with the rest remaining in the gastrointestinal tract until expelled in feces, and it is 600-times sweeter than sucrose; and stevia It is a heat-stable sweetener of natural origin and 200 to 400-times sweeter than sucrose (3).

For example, Ace-K was found to increase the weight of male mice and disrupted their healthy gut microbiome. Further research will determine whether Ace-K is also detrimental to humans. Moreover, it remains in the environment for a long time, making it a possible environmental contaminant. 

Contrary to initial belief, artificial sweeteners such as sucralose are not fully digested by humans and animals and can significantly alter blood glucose and insulin levels. Also, a small study concerning mice has shown sucralose to be a weak mutagenic. 

Studies have shown that sucralose and acesulfame-K cause enteroendocrine cell stimulation, which which modify intestinal movement. Acesulfame-K also exerts antimicrobial activity because it belongs to the chemical class of sulfonamides. Thus, acesulfame-K could significan-tly impact the content and microbial diversity of the gut microbiota. (3).

But there is good news as well: the plant-based sweetener stevia is extracted and purified from the Stevia rebaudiana Bertoni plant. Despite being significantly sweeter than regular sugar, stevia isn’t carcinogenic, doesn’t cause tooth decay, does not alter appetite, and does not increase blood sugar levels after taking MiO.

MiO does have caffeine (found in guarana). Caffeine has addictive properties; when habitual consumption abruptly stops, symptoms of withdrawal include headaches, fatigue, irritability, muscle pain, difficulty focusing, mood changes, nausea or vomiting (2).
