I hadn't heard that. I did a google search and saw a comment on the "Whitney Blog" but couldn't find anything more. They did have a redesign of all their bottles but I wasn't aware it coincided with any change in formulas? Although, you do get slightly less for the same price. I've been using it for 7ish years and have referred a lot of people to their products who tend to love them. The kits are a steal to try the stuff.
