Water kefir is a fermented, carbonated beverage that is produced using water kefir grains.
Also known as tibicos, California bees, Japanese water crystals and other names, water kefir is thought to have originated in the late 1800s.
Unlike regular kefir, which is made from cow, sheep or goat milk, water kefir is made by combining sugar water with water kefir grains — a type of grain-like culture of bacteria and yeast.
The mixture is then typically fermented for 24–48 hours, producing a probiotic beverage rich in beneficial bacteria.
Water kefir is not only delicious and easy to enjoy but also packed with health benefits and can be an excellent addition to a well-rounded, nutritious diet.

While current research is limited to test-tube studies, some research suggests that water kefir could help decrease the growth of certain types of cancer.
One study found that kefir extract was effective at blocking the growth of breast cancer cells (
However, more research is needed to evaluate how water kefir may impact the growth and development of cancer cells in humans.

Studies show that certain strains of probiotics could help reduce your risk of intestinal infections, prevent the recurrence of urinary tract infections in women and even keep respiratory infections at bay (
In animal studies, kefir has also been shown to help suppress inflammatory responses triggered by issues like asthma (
Plus, one small six-week study in 18 people found that consuming kefir daily was able to control inflammation and optimize levels of immune cells in the body (
Water kefir may help reduce inflammation and alter levels of immune cells to enhance immune function. Due to its probiotic content, it may aid in reducing your risk of certain infections as well.
Traditionally, kefir is made using cow’s or goat’s milk combined with kefir grains to produce a thick, probiotic-rich beverage.
However, since water kefir is made using sugar water, it’s a good option for those who choose to avoid dairy, either due to health concerns, dietary restrictions or personal reasons.
Particularly for those following a dairy-free or vegan diet, it’s perfect for bumping up probiotic consumption and boosting gut health while minimizing consumption of animal products.

Though studies generally show that probiotics are safe for these individuals, some case reports suggest that probiotics may be associated with a higher risk of infection (
Water kefir may cause digestive issues in some people. Concerns have also been raised about probiotic use in people with weakened immune function, though evidence is mixed.
Water kefir is incredibly flavorful, making it easy to take advantage of the multitude of health benefits this beverage provides.
The taste can vary based on many factors but is often described as slightly sweet with a bit of a flat aftertaste.
To make it yourself, combine 1/2 cup (118 ml) of hot water with 1/4 cup (50 grams) of sugar in a jar and swirl the mixture together to dissolve.
Next, add about 3 cups (710 ml) of room-temperature water to the jar, along with your water kefir grains.
Cover and place the jar in a warm area with a temperature around 68–85°F (20–30°C) and let it ferment for 24–48 hours.
The water kefir grains can then be separated from the mixture and added to a new batch of sugar water, while the completed product is ready for you to enjoy.
You can drink water kefir as is or experiment with different flavorings like vanilla extract, fruit juice, frozen fruit or mint leaves for a refreshing and tasty treat.
