Yogurt or curd is no longer the only source of supplementing probiotics. Probiotics are available in various formulations to cater to the needs of infants, children, adults and elderly people. These include infant foods, reuteri drops, capsules, powders, juices, probiotic curds and ice creams. Food products such as cheese, cereals and unfermented milk also serve as probiotic carriers. Additionally, probiotics are available as over-the-counter drugs and prescription drugs, etc. These products often contain dried, concentrated microbes packaged into sachets, capsules, or tablets.
