Our gut bacteria play a huge role in our digestive system – and apparently our total friendly bacteria can weigh around 3 pounds! In fact, these bacteria are so important that they are often referred to as an organ themselves. They help to digest food, preventing problems like constipation, flatulence, bloating, and malnutrition. While some foods naturally contain friendly bacteria, the best way to guarantee your probiotics will work are by buying a supplement version. Solgar’s Probi 20 Billion is a perfect example – it contains 20 billion live cultures, of Lactobacillus plantarum LP299v specifically. This kind of bacteria has been shown to survive the harsh acidic environment of the stomach, so you can rely on them to do their job! These lactobacillus probiotics are also suitable for vegetarians and vegans. To find out more about probiotics, read our article on why probiotics are so important.
