The red raspberry Rebus ideas is the natural source, but you would have to eat 90 lbs daily to realize the proposed health benefits you can now get in convenient capsule form through the gift of modern laboratory science. Eating crates and crates of juicy sun-ripened fruit sounds nice if you love the heavenly smell and taste of ripe raspberries (who doesn't?), but the natural sugar content would offset the ketone slimming effect you desire. For the positive effects, minus the sugar, we have designed and produced our Raspberry Ketones diet products here in the USA in FDA inspected and GMP approved facilities.
