Evidence check: AMH in the context of Darmgesundheit

The query asks for evidence on AMH (anti-Müllerian hormone) in the context of gut health. The provided knowledge context contains no studies or statements linking AMH to the gut microbiome or intestinal health. AMH is a well-established marker of ovarian reserve used in fertility medicine. The concept of a gut–AMH axis is speculative and unsupported by the sources here. Even if some mechanistic hypotheses exist (e.g., via inflammation or hormonal crosstalk), no robust human trials are cited. Consumers should be cautious of tests that market AMH for gut health without solid evidence. The evidence grade is therefore 'unclear' or 'marketing'. Safety note: AMH measurements alone are not appropriate for assessing gut health; clinical interpretation is necessary.
