Your intestinal tract contains trillions of bacteria that perform a wide variety of functions including digestion and assimilation of foods and nutrients, and proper elimination of waste products and toxins. This colony of good bacteria is called the Microbiome and it is crucial to your overall health. Studies have shown that the healthy bacteria in your intestinal tract play an essential role in your immune system and are a first line of defense against unhealthy bacteria that can cause illness.
However, the healthy bacteria can become depleted due to illness, poor diet and antibiotic and other drug use leading to an unhealthy Microbiome. Single strain probiotic supplements contain healthy bacteria that are designed to replenish the bacteria in your intestinal track. Probiotic supplements come in either single strain or multi-strain varieties.
Single strain probiotics can be used when there is a specific kind of bacteria that is lacking in your system. They can also be used if the particular strain has been proven to have a specific health benefit such as helping to control a kind of unhealthy bacteria, promote skin health, and benefit vaginal health to list a few examples.
Some health issues that have been shown to improve with probiotic use are constipation or diarrhea, vaginal yeast infections, skin conditions such as psoriasis, eczema and acne as well as digestive issues.
Probiotics are generally kept in a cool, dark environment or refrigerated although they are stable enough for shipping purposes. They do not spoil like a dairy product such as yogurt, kefir or other dairy products which contain probiotics.
