Catalase is present in most living organisms.
Its main function is to convert hydrogen peroxide or ‘oxygenated water' into a molecule of water and a molecule of oxygen gas, as in the reaction: H2O2 = 2H2O + O2.
Hydrogen peroxide is a by-product of many metabolic reactions that must be eliminated as soon as it forms. Without the intervention of catalase, accumulation of hydrogen peroxide would be fatal.

¤ Catalase is a globular protein formed of four identical chains of amino acids (each over 500 amino acids long); each chain includes a chemical group called ‘heme', an organic molecule containing an atom of iron.

¤ Catalase is found in all aerobic organisms, particularly in turnips, most plant roots, yeast, and liver.

¤ To date, its use has been typically limited to bacteriology - for identifying particular bacteria. When bacteria are added to hydrogen peroxide, effervescence will occur if catalase is present, as a result of the release of dioxygen.

¤ The last few years have seen the publication of important studies on catalase which have expanded its range of applications.

¤ In particular, is catalase's potent capacity for combatting oxidative reactions - the same process that makes metal rust. Catalase can protect cell membranes and DNA from this damaging oxidation process.

¤ Research at the University of Washington School of Medicine investigated mice that had been genetically modified to produce a surplus of catalase in specifically targeted parts of the body - the cells' cytoplasm, the nucleus where DNA is stored and the mitochondria - the cell's power plant.

¤ Results showed mice that produced more catalase in the mitochondria lived on average 20% longer. Those with more catalase in the nucleus and cytoplasm saw only a slight increase in lifespan. The research also suggested that catalase supplementation may strengthen cardiac muscle and protect against age-related heart problems.

¤ In addition, catalase is used to slow or reverse premature greying of the hair because it neutralises hydrogen peroxide and its oxidative potential. (see Grey Hair Formula).

¤ Other studies will undoubtedly expand its range of applications still further.

¤ Given its polyvalence and lack of toxicity, it makes sense to start including catalase as part of any anti-ageing programme.

Adults. Take 2 capsules a day.
Each vegetarian capsule contains 250mg catalase, ie 6250 units of catalase activity (CatU).
