Taking beta-sitosterol significantly lowers total and bad (LDL)
cholesterol levels, but it does not raise good (HDL) cholesterol levels;
Benign prostatic hyperplasia
Improving the symptoms of BPH, but it does not actually shrink an enlarged prostate;
Immunomodulatory effects
Initial studies have shown that β-sitosterol can increase the
proliferation of peripheral blood lymphocytes and enhance the cytotoxic
effect of natural killer cells.
Anticancer properties
β-sitosterol has demonstrated effects on tumor cell lines in vitro.
Growth is inhibited in human colon, prostate, and breast cancer cell
lines. It has been postulated that cell death (apoptosis) is initiated,
probably by activation of the protein phosphatase A2 pathway.
