When to drink kefir: advanced analysis based on your gut microbiota

To delve deeper, understanding when to drink kefir requires taking into account an often-overlooked element: the gut microbiota. Each person has a different microbiota, which explains why some tolerate kefir very well on an empty stomach, while others immediately experience bloating.

Kefir contains microorganisms produced by fermentation. These live cultures can interact with your existing gut flora. If your gut microbiota is already diverse and stable, introducing kefir is generally well tolerated, regardless of when you consume it.

However, if your gut microbiota is unbalanced (due to stress, a poor diet, or recent antibiotic use), choosing the right time to drink kefir becomes crucial. In this case, taking it with meals often helps to minimize adverse reactions.

In practical terms, this means that the best time is not universal, but depends on your digestive system.
