Difference between antioxidant capacity (ORAC) and antioxidant bioavailability?
Antioxidant capacity (ORAC ranking) and antioxidant bioavailability sound similar but they are two very different things!
In simple terms, one is measured outside the human body, and the second one is measured inside the human body.
ORAC can tell you which plant foods are high in antioxidants. But it cannot tell you how much of those antioxidants your body will effectively absorb!
Antioxidant bioavailability is your body’s capacity to assimilate and absorb the antioxidant compounds of a plant food into your system.
