Concentration ™  is a great tasting, natural fruit-flavored citrus cooler containing choline and essential nutrient cofactors. This Designer Food® dietary supplement is designed by Life Extension scientists Durk Pearson & Sandy Shaw® for their own daily use.

Some of the choline in your diet is used by your brain and motor nerves to make the neurotransmitter acetylcholine, which is critical for proper memory function and muscle tone.* Use Concentration ™ for Creative Energy. You'll love the taste - you'll love the feeling!
