Sona Acidophilus Complete capsules consist of ‘friendly’ bacteria that help to re-establish and maintain a favorable intestinal flora- especially during and after a course of antibiotics. Beneficial bacteria- such as Lactobacillus acidophilus and Bifidobac-terium bifidum- are called probiotics. Probiotic bacteria favourably alter the intestinal microflora balance- inhibit the growth of harmful bacteria- promote good digestion- boost immune function- and increase resistance to infection. Acidophilus and bifido bacteria maintain a healthy balance of intestinal flora by producing organic compounds—such as lactic acid- hydrogen peroxide- and acetic acid—that increase the acidity of the intestine and inhibit the reproduction of many harmful bacteria. Probiotic bacteria also produce substances called bacteriocin- which act as natural antibiotics to kill undesirable microorganisms. Sona Acidophilus Complete capsules are made of the highest quality and provide 2 billion viable organisms per capsule.
