We built three package sizes because different people are at different points in deciding whether FlexGuard fits their routine.
If you're trying FlexGuard for the first time and want the lowest upfront commitment, this is the option. It's also the smallest window to judge gradual results in — most people need more than a month to notice a meaningful change.
A middle ground that gives the formula roughly three months of consistent use — closer to the timeline our own honest expectations section describes, and it includes free US shipping.
The lowest per-bottle price, free US shipping, and the longest runway for consistent, gradual use. If you're already fairly confident joint support is something you want to commit to, this is the most economical way to do it.
Since results build gradually and vary from person to person, a multi-bottle package simply gives your body more time with consistent use. We'd rather you go in with realistic expectations about the timeline than feel like month one somehow didn't "work."
