Probiotics are living microorganisms that have beneficial effects on the human body. Certain probiotics have shown to have an impact on maintaining kidney function in people with impaired or damaged kidneys. The 3 types of bacteria have been specially selected for use in Renadyl^TM - Streptococcus thermophilus, Lactobacillus acidophilus, & Bifidobacterium longum.

Prebiotics are naturally occurring fiber materials that may be digested by probiotics to help them grow. Renadyl^TM contains a prebiotic called psyllium husk (naturally occurring plant material).

Synbiotics are supplements that contain both a prebiotic and a probiotic. The majority of probiotics on the market today, including Renadyl^TM, are considered "synbiotic." The main reason for using a synbiotic is that a true probiotic, without its prebiotic food, does not survive well in the digestive system.

There is an amazing amount of bacterial cells associated with the human body. Most are not harmful, and many contribute to normal human growth and development. It is believed that good gut bacteria make up about 70% to 80% of the body's total immune system. However, some can have a negative influence and cause various diseases. That is why it's important that the balance of microbes be maintained to favor the beneficial bacteria over the potentially harmful ones. The ratio of beneficial to potentially harmful bacteria in the gut should be 80/20. Probiotics help maintain a proper balance of good bacteria and bad bacteria in the body.
