Phytase

What is Phytase?

Phytase is a naturally occurring digestive enzyme that breaks down phytic acid, also known as phytate, that is found in many plant foods such as whole grains, seeds, nuts, legumes, and pulses. Small amounts of phytase are naturally produced in the human gastrointestinal tract; however, these levels are typically low, leading many individuals to benefit from supplementation.

Health Benefits:

Enhances Digestive Health

Reducing phytate content may improve overall digestive efficiency and reduce the inhibitory effects of phytic acid on protein and starch digestion. Phytic acid can bind to essential minerals, forming complexes that reduce their absorption in the human digestive tract. Phytase hydrolyses phytic acid, helping to release these bound minerals so they can be more effectively absorbed and utilised by the body. One study found that birds showed heightened levels of calcium, phosphorus, iron and zinc following phytase supplementation, and further research showed that phytase enhanced iron and zinc absorption from phytate-rich foods for humans.

Bone Health Support

By supporting the availability of the essential minerals, phytase may contribute to the maintenance of healthy bones and teeth. One study found that being fed phytase-supplemented diets had beneficial effects on bone mineral content, bone area and bone mineral density for rats. Another study found that phytase supplementation led to increased mineral levels (including calcium, iron and zinc), reduced bone porosity and higher levels of bone mineralisation in birds.

Typical Use:

Phytase is commonly used as an ingredient within dietary supplements to provide digestive health benefits, and is often combined with mineral formulations to promote mineral absorption. Supplements containing phytase are especially well suited to those following a vegetarian or vegan diet, which tend to be higher in phytate containing foods and may be more susceptible to reduced mineral bioavailability. This enzyme is also regularly used within functional foods such as within breads, dairy alternatives and plant-based drinks.
