Your gut microbiota influences everything from digestion and immunity to metabolism and mood. The Zinzino Gut Health Test reveals your gut’s functional output — what your gut bacteria are actually producing — and how that activity is affecting your overall health. This easy at-home test analyses key markers of gut, immune, and metabolic balance, giving you a clear insight into how well your body and gut bacteria are working together.
