Calcium and vitamin D
This article was originally published in The Tan Sheet
Executive Summary
Vitamin D serum levels and calcium supplementation "appear to act largely together," a study in the Dec. 3 Journal of the National Cancer Institute finds. Maria Grau, MD, Dartmouth Medical School, Lebanon, N.H., et al. analyzed data from a previous trial on calcium for prevention of recurrent colorectal adenoma (1"The Tan Sheet" Jan. 18, 1999, p. 17). Vitamin D status "strongly modified the effect of calcium supplementation on adenoma recurrence," the authors report, adding that further study is needed on both the mechanism of interaction and "to clarify the amount of intake of each nutrient required for optimum protective effects"...
