Probio7 Professionals AB21 is a probiotic that can be taken year round, but is especially important to take during the winter months. The lungs host a community of bacteria that communicate with the gut microbiome, forming a vital connection known as the gut-lung axis. This axis plays a crucial role in protecting against respiratory diseases and infections, making it essential to maintain a healthy balance in the gut microbiome. The carefully studied blend of AB21 strains supports this complex axis with 2 billion live, friendly bacteria in each capsule. Additionally, this supplement includes 400 IU of the superior form vitamin D3, promoting strong bones, teeth, and a robust immune system. These convenient probiotic capsules don't require refrigeration and are gluten-free, vegan, and free of artificial flavours or preservatives.
