    Renew Life has a focus on natural products that are formulated to support digestive and total body wellness. It was founded in 1997 with a motto: A healthy gut is a happy gut. Founders Brenda and Stan Watson's strong focus on digestive supplements began when Brenda developed a chronic illness. They soon came to realize the importance of the human gut in becoming healthy again. To help the healing process,they began formulating their own line of digestive wellness supplements using only pure, raw ingredients found in nature. The company's commitment is to provide supplements with superior quality ingredients and without artificial ingredients, colors and preservatives.
    Fiber (e.g., flaxseed, fennel seed, slippery elm bark) is well-known for its ability to promote the formation of stool as well as increase the frequency of bowel movements, thereby targeting digestive issues [1-4]. L-glutamine is an important amino acid that plays a role in cell health as well as wound healing [5]. Probiotic supplementation, mostly with Lactobacillus strains, is also associated with a reduced incidence of duration of diarrhea that is due to antibiotic use [6]. In addition, probiotic supplementation with Lactobacillus and Bifidobacterium strains in particular, is frequently used in hospital settings to target diarrhea that is caused by antibiotics [7]. Prebiotics (e.g., Fructooligosaccharide-FOS) provide nutrients that enhance the growth and activity of the probiotics [8]. Lactobacillus and Bifidobacterium are the most commonly used probiotics [9].
    Enhanced digestion, improved health [1-10]
    Flaxseed and fennel seed consist mainly of fiber that absorbs very large amounts of water, which causes the fiber to swell and form a soothing gel that supports digestive health [1, 2]. Slippery elm bark (Ulmus rubra) contains a form of soluble fiber called mucilage, which traps and absorbs water, thereby forming a gel-like substance that helps coat mucous membranes. In doing so, it targets digestive pain and discomfort [3, 4]. L-glutamine plays a role in enhancing the activity of proteins and enzymes that promote wound healing, thereby improving the health of the digestive tract for people experiencing discomfort [5]. Probiotics restore and maintain a healthy balance of good bacteria in the gut [10]. Probiotics also release enzymes that promote the digestion of food and enzymes that target bad bacteria as well as other harmful invaders, thereby improving overall digestive function [11]. In addition, they support the proper breakdown and transport of nutrients into the bloodstream and throughout the body [8]. By improving the digestive process, probiotics helps ensure that only low amounts of undigested food remain in the gut as undigested food often leads to stomach discomfort. In doing so, probiotics target bloating, constipation, gas, and diarrhea, especially when antibiotics are being taken [6]. Probiotic supplementation is frequently recommended during and after antibiotic use because it restores healthy levels of good bacteria [7]. Probiotics boost natural antioxidant activity in the body and this takes some of the strain off of the immune system [12]. Therefore, immune system becomes stronger and more readily available to target foreign invaders due to added protection that is provided by probiotics.
