Lit-stop phytate source by Biowise is a food supplement based on rice bran extract, oat fiber and wheat germ, enriched with phytin, vitamin A and zinc that complements a diet unbalanced in phytate. Phytate is an inhibitor of the formation of calcium oxalate and calcium phosphate crystals. The dietary sources of phytate are whole grains, legumes, and nuts. A healthy diet rich in phytin, vitamin A, and zinc improves urine quality. Consumption of foods rich in phytate helps reduce the risk of calcium lithiasis.
