While some observational studies have found associations between low chromium levels and increased rates of dyslipidemia, high blood pressure, and cardiovascular disease,[1][2] these results have not been consistent[3][4] and many of these studies failed to control for dietary chromium intake.
A 2023 umbrella review of 8 meta-analyses failed to find significant effects of chromium on various lipid markers, including triglycerides, total cholesterol, low-density lipoprotein (LDL), or high-density lipoprotein (HDL).[5] Similarly, chromium doesn’t seem to affect the level of apolipoproteins A or B.[6] The reported effects of chromium on blood pressure have been mixed,[7][8] but a 2022 meta-analysis did not find any effect of chromium supplementation on systolic or diastolic blood pressure.[8] Overall, current evidence does not support the use of chromium for dyslipidemia or high blood pressure.
