The human body is comprised of diverse micro-ecosystems of bacteria, each which have unique and varying functions within the body. Most of these bacteria are beneficial – these ‘good’ bacteria are known as probiotics. Probiotics can assist your body to produce vitamins, absorb nutrients from your food, and even help regulate your mood. Probiotic bacteria can also serve as placeholders, taking up room by colonising within your digestive tract so that other bacteria can’t settle in, multiply, and create chaos for your system.
