Stomach upset caused by saw palmetto may be reduced by
taking it
with food. Some men using saw palmetto report difficulty
with erections, testicular discomfort, breast tenderness or enlargement, and changes in sexual desire. Saw palmetto may have effects on the body's response to the sex hormones estrogen and testosterone, but no specific effect has been well demonstrated in humans. It would be best to discuss this with your doctor for proper evaluation and for alternative supplements.
