Probiotics are the "good" bacteria that may play an essential part in maintaining intestinal health. FiveLac contains five potent micro-flora replenishing your system with over 2 billion live bacteria which help keep your digestive tract healthy. Designed to provide selected beneficial microflora to the intestinal tract for the purpose of replenishing needed friendly flora to promote intestinal health. The prevalence of intestinal imbalance makes a focus on probiotics essential. Prevention of overgrowth before it occurs is clearly the better alternative. Probiotics may be a safe, cost-effective, "natural" approach that may help act as a barrier against microbial infection such as yeast overgrowth. Friendly flora perform a number of constructive functions in the intestinal tract. One main function is to help prevent occasional good/bad flora imbalance. The "good" flora do this by crowding out the "bad" in the intestinal tract. Some common indicators of flora imbalance may be: Melancholy Anxiety Irritability Heartburn Indigestion Extreme food and environmental allergies Lactose intolerance Acne Dry skin Itching Jock itch Vaginal health FiveLac Active Ingredients Bacillus coagulans: A probiotic organism that may help control occasional digestion and stomach problems. Bacillus subtilis: A probiotic organism that may help crowd out "bad" flora in the intestines. Enterococcus faecalis: Enterococci constitute a major genus within the lactic acid bacteria group that exists naturally in the human digestive tract. This effective probiotic bacteria is the result of formulation under strict laboratory conditions. Lactobacillus acidophilus: These friendly bacteria inhabit the intestinal tract. The breakdown of nutrients by L. acidophilus produces lactic acid, hydrogen peroxide, and other by-products to enhance optimal intestinal flora. Bifidobacterium longum: B. longum may help keep the digestive system running smoothly.
