Antioxidants are needed to balance the
oxidants produced by and present in the body
Antioxidants sacrifice themselves to preserve our body parts
from damage by
Antioxidantsare water-soluble and/or fat soluble:
– Fat soluble –E.gVitamin A, Vitamin D,Vitamin E,Vitamin K and CoEnzyme Q-10; protect cellular plasma and nucleic
membranes (housing DNA) from lipid peroxidation. Canfield LM et al.
Anti-oxidant/pro-oxidant reactions of vitamin K. 1985
Fat soluble vitamins can be stored in the body (except
K storage is minimal).
– Water SolubleE.g. Vitamin C,
alpha-lipoic acid -provide oxidant damage control in the
blood and cell plasma. Water soluble vitamins
can NOT be stored in the body.
Where do they come from?
– Produced “In-House”by the body – E.g.
Superoxide Dismutase (SOD),
Catalase (CAT), Glutathione Peroxidase (GPx), Glutathione (GSH),CoQ10 (production
decreases with age)
Antioxidantsneed optimal amounts of
certain dietary, MINERALS to function properly
