No effect of a single application of liver support preparations, such as Cholispar, Essentiale, Artichoke, Milk thistle, on the results of laboratory tests, including the result of the so-called liver tests, has been reported. However, regular use of preparations reduces liver parameters due to the effect of, m.in. on liver regeneration. Discontinuation of the preparation may again cause deterioration of the determined liver parameters. I encourage you to inform the doctor interpreting the test results about the preparations used. This will facilitate further supplementation.
