I recently learnt that I have above range prolactin levels. I think the range is around 0-400~. A few months ago I had a reading of around 900 which raised alarms for my GP who sent me to have an MRI scan done. The MRI report suggested that it was possible I had a prolactinoma (benign tumor of the pituitary gland) but since seeing a specialist he does not think I have one. I have had two follow up blood tests which were much lower, but still around 500~. He does not think I need to worry any more about it even if it is a little over the typical range, but after doing some more research I've found plenty of studies that suggest Arginine raises prolactin.
I've regularly used pre-workout NO products over the last 4-5 years but more so, I take regular protein shakes which seem to also include arginine. Optimum Nutrition gold standard whey has 480mg arginine per serve.
I'm not experiencing any sides such as lactating or libido loss at all, however I'm wondering if higher levels of prolactin can make me feel fatigued, etc? Has anyone got any studies/blood test that have shown prolactin to raise as much as it has in my case from arginine?
I don't want to go taking anything crazy to drop it (I'm not sure if I will have any positive effects by dropping it?) but would something like mucuna or another natural herb drop this to a lower level? Is there anything I could hope to gain out of dropping it?
Thanks for any input you have.
