Promotes Digestive Health: Gastrus 30 Probiotic Chewable Tablets contain live and active cultures of the beneficial bacteria, Lactobacillus reuteri, which can help improve the balance of good bacteria in the gut. This can lead to better digestion and alleviate common digestive issues such as bloating, gas, and diarrhea.
2. Supports Immune System: As a major part of our immune system resides in our gut, keeping it healthy is crucial for overall immune function. The probiotics in Gastrus 30 can help strengthen the gut microbiome, leading to a stronger immune system and better defense against illness and infections.
