People who take excessive amounts of
carotenoid supplements may find the palms of their
hands and soles of their feet take on a yellowish
orange discoloration. This is a temporary effect that
wears off when stopping the supplement allows the
amounts of carotenoids present in the body to
decrease. Taking zeaxanthin with foods that con-
tain some fat increases the amount of zeaxanthin
that enters the bloodstream from the digestive
tract. Taking penicillin-based ANTIBIOTIC MEDICATIONS
may decrease zeaxanthin absorption.
