How long can this product be kept in the fridge for without losing its potential? Can an extra bottle be stored in the fridge for a month?

Michael,This is Colleen from MaryRuth Organics. An unopened bottle is good for 2 years from when it was made. That date is on the bottom of the bottle. An opened bottle must be refrigerated and an opened bottle will last 6 months.Yes, you can keep an extra bottle in the refrigerator. Again, that bottle will last 2 years unopened and 6 months if you have opened it.Please let me know of any other questions you may have.Kind regards,Colleen

Is it a glass bottle?

The bottle is PETE plastic and BPA free! We considered glass, as that would be ideal, but I was informed by Amazon that glass bottles would be broken on route during shipment. So the next best thing is we obtained a bottle that is PETE plastic designated with a recyclable `1', meaning it can be thrown away into any type of recycling bin. What's interesting about PETE is it is globally recognized as a safe, recyclable packaging material. Numerous scientific tests have created a broad scientific consensus that PETE is non-toxic and a safe material for the storage of food, beverages and liquids. Please let me know if there's any other questions you may have.Kind regards, Colleen colleen@maryruthorganics.com

I do not see an k2 in the morning or evening formulas that is supposed to increase calcium absorption as well as vitD&A. Is it in there?

Please offer 2 variants. With vitamin K2 to help absorption of calcium and to prevent calcium buildup on artery walls. Without K2 for those who cannot intake. Thanks

Is the trace mineral blend certifies free of heavy metals like the one in the morning mix? I want to give it to my kids so it needs to be zero metals

C.L.Yes, the nighttime multi-mineral has been "Tested to be free from aluminum, lead, mercury and other heavy metals." and is marked on the bottle. Once on the Amazon page showing the product you will see small boxes with photographs to the left of the product and you can view all sides of the bottles.Please let me know of any other questions that you may have.Kind regards,Colleen
