The extract contains 12% Ca.sup.2+, 1% Mg.sup.2+, and detectable amounts of 72 trace elements, but essentially no organic material. The red algae extract was as effective as inorganic Ca.sup.2+ alone in suppressing growth and inducing differentiation of colon carcinoma cells that are responsive to a physiological level of extracellular Ca.sup.2+ (1.4mM). However, with cells that are resistant to Ca.sup.2+ alone, the extract was still able to reduce proliferation and stimulate differentiation.
