Memory for MacBook Pro - Early 2011

I have a 2011 MacBook Pro that is running slow. It currently only has 4 GB of RAM installed in two 2GB modules. per Apple the maximum is 8 GB. However looking at the website Everymac.com it says it can handle up to 16 GB in total. I am wondering if anyone can tell me if that is correct. Also, any thoughts on best place to order the memory from. Thanks.
