Beetroot juice (also known as beet juice) has been shown in clinical trials to improve aspects of exercise endurance or performance but only in certain situations. The effectiveness of beetroot juice may come from its nitrate content, which, when converted in the body into nitrite and nitric oxide, can improve blood flow to muscles. Sign in to get the details about beetroot juice as well as how beetroot juice supplements from different brands compare on nitrate levels.

I have a patient using SuperBeets I believe that since starting and checking her hormone levels of thyroid (a complete panel) and gonadal hormones and her FT4, FT3, estradiol, progesterone and free and total testosterone levels all came back super high. I don't know if this could be from supplement and represents an interference with the test or an actual physiologic effect of the supplement but it's the only thing she's changed. I repeated the labs to be sure it wasn't a lab error and they came back the same.

Hi Rebecca - We are not aware of reports of beets, beetroot juice, or SuperBeets (which can include additional ingredients) interfering with diagnostic tests. We are just speculating, but the red pigment in beets does make it into the blood (and, eventually, into the urine), so there is a possibility that assays that are colorometric might be affected.
