Synergy, not quantity or amounts, is one of the keys to effective nutrition. (Synergy is the interaction among the hundreds of nutrients contained in vitamins and minerals, all working together.)
Functional nutrition research shows extremely small amounts of a wide array of natural nutrients is usually more beneficial, than large amounts of isolated nutrients. The body more easily uses them.
There is also a cooperation between certain vitamins and minerals, promoting absorption. Correcting a deficiency in one vitamin or mineral requires the addition of others, not simply replacement of the deficient one.
(This is why the 18 fruits and vegetables in BarleyLife Xtra were chosen, because they work even better together.)
Synergy, not necessarily quantity, is one of the keys to effective nutrition.
