How old is my bottle?

The stamp/code on the back of the bottle will help determine the date it was manufactured.

For example: 16264-87649-2233. This bottle based on the code was made on the 264th day of the year 2016. In the first five numbers, the first two numbers determine the year (in this case 16) and the last three numbers (264) tell you what day in the year based on the JULIAN Date Calendar.
