Do probiotics and prebiotics boost immunity?

Anthony L. Komaroff, MD
Internal Medicine
The jury is still out on whether consuming probiotics or prebiotics can confer health benefits, including any effect on the immune response. The direct connection between taking these products and improving immune function has not yet been made scientifically. In fact, changing the balance of bacteria already long established in the human gut may not be possible. That's very different from working with mice made germ-free in the lab, where it's relatively easy to establish new colonies of bacteria.

Food or supplements that contain prebiotic fiber such as larch arabinogalactan, promote digestive health. Larch arabinogalactan is also clinically proven to naturally activate your immune system.
