Acidophilus is a certain type of bacteria which is often referred to as a probiotic. Probiotic comes from the meaning “ pro-life”. In the human digestive system , we have naturally occurring bacteria which keep the immune system , digestive system & genital area clear from infections and diseases. The purpose of having our own bacteria is to prevent other unhelpful bacteria from taking over the body causing it harm. Acidophilus capsules normally contain other forms of beneficial bacteria , which when combined can help with the prevention of vaginal infections (in women); diarrhea; irritable bowel syndrome; eczema; colitis. Beneficial bacteria have also been shown in some research to improve immune health and control cholesterol levels.
