Some days you might not feel like mixing or blending shakes. Ready To Drink (bottled) shakes are very convenient for when you’re on the go or just feeling a little lazy. The convenience comes at a price, however, as they cost a lot more per serving than the powder mix. Also, you can’t customize ready to drink shakes like you can with powder shakes (for example, blending with ice for a thicker shake, etc.). Still, it’s good to have the ready to drink shakes handy so that you never have an excuse to fall off your plan. Check out the selection of popular ready-to-drink meal replacement shakes below.
