The RnA Drops products are bottled in glass and the ReMag, ReMyte, ReCalcia and ReAline are in PET plastic bottles. PET is a biologically inert material that doesn't react with foods or beverages and is resistant to attack by micro-organisms. It's been thoroughly reviewed and approved as safe for contact with foods and drinks by the FDA, Health Canada, the European Food Safety Authority and other international health-safety agencies. It has also been used by consumers around the world for more than 30 years without any known adverse effects.
Extensive testing of PET and PET packaging has repeatedly shown it to be safe. PET itself is biologically inert if ingested - meaning you could EAT the bottle and nothing would happen to you!!!
We continually review our quality processes and our manufacturing standards so glass bottles have been discussed. At this point they are cost prohibitive for product content that is designed for 30 days use. If it were a product that would be stored for two years or some such thing the cost might justify itself.
In the meantime, just know that so far we haven't had a bottle of ReMag sit in our warehouse for more than 6 weeks before it is shipped to our customer - that is how fast the products fly off the shelves.
Most customers who ask about our bottles are concerned about 'leeching' and in the case of the PET bottles the factors that drive the 'leeching' process are extreme heat and age. In our case, neither one of these is a factor in the 7 weeks the bottle could be waiting to come to your house and hopefully once you get the product you'll use it as directed and the contents will be gone with 48 days :)
