Catalase

Is there any way to increase the enzyme Catalase? I understand that the lack thereof contributes to greying of hair. I also understand that any "catalase supplement" is largely ineffective b/c when it is ingested it is denatured by stomach acid. As a matter of fact, I read that it becomes denatured by anything acid OR alkaline. Are you aware of any natural method to supply this enzyme or encourage it. What else can be done to combat naturally occurring hydrogen peroxide in our bodies?

I found this claim interesting. While I do not have an issue with grey hair, my dearest friend is quite grey. She asked that I inquire. Tweet
