diatomaceous earth.....how long does it last?

I have bought medical grade diatom from www.diatomx.co.uk The site looked quite nice, has tons of information and does different types of Diatom but I bought the white powdered version as I have read it is good for cutting cholesterol levels, has anyone else experienced this?

ps, from what i have read, it has 90+% silicone which is good for you and less than 3% of this is crystalline silicone so it relatively harmless when inhaled. It is the cheaper stuff that is over 5% crystalline silica that can cause lung silicosis

I only know that I use "food grade" and it says "food grade" here in the USA. A 50 pound bag lasts me about 3 years. I keep about a dozen chickens at any one time.
