Subject: antioxidants
Had some problem with first post, here's a repeat.
=20
Have recently attended a presentation on the above by a
Prof Halliwell. I would like to run it and related queries,=20
by the list for opinions. Superoxide anion damage to DNA
was tracked by tracing 8OH deoxy Guanine, in urine.
=20
1 Subjects were given a commercially available antioxidant,
8OH dG was found in increased levels and study terminated
at 2 weeks.
=20
2 Same set of subjects were given 500gm of raw tomatoes,
{once a day} 8OH dG levels decreased and leveled off. Study =
terminated.
=20
3 When asked, he said that persons exposed to hyperbaric
oxygen showed an initial increase in degradative products, but levels
gradually decreased to pre-exposure levels. Time line not
mentioned.
=20
Aside, my questions are:-
=20
Commercially available preparations of SOD, Catalase and
Glutathione Peroxidase don't make it the cellular level because
of protease action and stomach pH, and are therefore not worth
crap?
=20
If I'm planning preventive anti-ox therapy of vit E, C, Selenium etc
do I plan according to Ox Tox % per dive day or cumulative ox tox
per dive mission, or should I just go mega dose or saturation?
=20
Any feedback on pine bark extract?
