phy·tic acid

An antioxidant compound, C6H18O24P6, found abundantly in seeds and the bran of grain, that is the principal storage form of phosphorus in plants. Phytic acid is a strong chelator of calcium, zinc, and other minerals, and diets based on foods high in phytic acid, such as unrefined flour, can cause mineral deficiencies unless it is broken down by the sprouting of the seeds or by fermentation. Also called inositol hexakisphosphate.

[phyt(in), salt of phytic acid (from German Phytin : phyto-, phyto- + -in, -in) + -ic.]

The Buzz: "The natural product of the decade." That's what Enzymatic Therapy is saying of its new dietary supplement, Cell Forte with IP-6. Ads claim it boosts immunity by increasing natural killer cell activity.
The Basics: Cell Forte contains inositol and inositol hexaphosphate (IP-6) derived from rice bran.
The Bonus: Some scientists believe the lower cancer rates seen in populations that eat a lot of cereal grains may be due to IP-6, rather than the grains' fiber content.
