Incorporating probiotics, the "good bacteria" that can improve digestive health, can now be done while drinking iced tea.

Products like juices and ice creams have recently been introduced to provide alternative ways of increasing the level of helpful bactaria in the gut, and one company says that it’s new line of probiotic-based iced teas offer a summertime drink that can help.

The designers of the teas say that the new strain is more stable than older lactobacillus variants, which could improve benefits as it travels through acidic portions of the mouth and stomach.

Researchers at University Hospital in Lund, Sweden say that probiotics have also shown promise in reducing the likelihood of developing diseases in congested areas like hospitals.

They gave patients on ventilators a probiotic supplement swabbed inside of their mouth instead of using antiseptics commonly administered in hospitals.

The probiotic swabbing was as effective as the antiseptic in reducing cases of pneumonia, and the scientists say it came without the side effects of allergic reactions and tooth discoloration often found in current hospital practices.
