                                Research suggests that many individuals with lactose intolerance can handle up to 12 grams of lactose in a single serving without experiencing significant symptoms, roughly equivalent to one cup of milk. However, the exact amount that triggers a reaction is highly individual and depends on multiple factors, including the body's residual lactase enzyme activity.
