Overview

Wild kefir cultures, also known as kefir grains, are a symbiotic colony of bacteria and yeasts that are used to ferment milk or sugar water to create kefir, a probiotic-rich beverage. These cultures contain a diverse range of microorganisms that contribute to the unique flavor and health benefits of kefir.

Key Benefits

Promotes a Healthy Gut Microbiome

Kefir is a potent source of probiotics, which can help to increase the diversity and number of beneficial bacteria in the gut.

Supports Immune Function

The probiotics in kefir can help to modulate the immune system and may reduce the risk of infections.

Enhances Nutrient Absorption

The fermentation process in kefir can increase the bioavailability of certain nutrients, making them easier for the body to absorb.

Dosage & How to Take

There is no standard dose for wild kefir cultures. The amount of probiotics consumed will depend on the amount of kefir ingested. A typical serving of kefir is 1 cup (240 mL) per day.
