AMH levels reflect a woman’s ovarian reserve (egg supply), which decreases with age. This means a low AMH level is reflective of low ovarian reserve.
Some studies suggest that vitamin D and dehydroepiandrosterone (DHEA) supplementation may increase AMH levels. However, there is not enough evidence to show that these are effective at increasing chances of conceiving, as ovarian reserve will still naturally decrease with age regardless of whether a woman has a high AMH level. It is important to note that while a high ovarian reserve may indicate a higher chance of pregnancy, a low AMH level does not always mean that a woman will not be able to conceive naturally.
Women should discuss with their doctor before taking any supplementation to address any fertility issues.
