Fibrolytic

Phytase

A myo-inositol hexakisphosphate phosphohydrolase that sequentially removes phosphate groups from phytic acid, a common storage form of phosphorus in plants. This enzymatic action releases bound minerals such as calcium, magnesium, iron, and zinc, improving their bioavailability from plant-based foods and reducing the anti-nutrient effect of phytates.*

BIOCHEMICAL ROLE IN DIGESTION

Phytase hydrolyzes phytic acid (myo-inositol hexakisphosphate), a natural storage form of phosphorus in plant seeds that also binds essential minerals. By cleaving phosphate groups, phytase reduces phytate’s chelating capacity, thereby liberating phosphorus and improving the bioavailability of minerals such as calcium, iron, zinc, and magnesium. This enzymatic process addresses the nutritional limitations of phytate-rich plant-based diets.*

NUTRITIONAL RELEVANCE IN SUPPLEMENTATION

Supplemental phytase enhances mineral utilization in individuals consuming diets high in legumes, grains, and seeds. By degrading phytate, it improves absorption of key micronutrients often limited in plant-heavy diets. This can support bone health, energy metabolism, and red blood cell formation. Phytase supplementation is also relevant in vegetarian and vegan nutrition, where reliance on phytate-rich foods can otherwise reduce mineral bioavailability.*
