What Research Shows
May Not Be Effective
Editorial process and description of evidence categories can be found at EBSCO NAT Editorial Process.
It is likely safe to progesterone in small doses for a short time, but problems such as stomach upset, skin reactions, weight gain, and other side effects may happen. Not enough studies have been done to say whether it is safe to use for a long period or by women who are breastfeeding.
