thank you henni, i hope that your helpful post doesn’t shut down this thread and i am not being sarcastic.
i take a vitamin/mineral supplement that contains 100% rda.
my brother is a board-certified eye surgeon and years ago developed a supplement that addresses early onset of pre-surgery cataracts, which he has since morphed into supplements in general. he explains it in true bitog-fashion: imagine that your body is a car engine and your daily intake of vitamins/minerals is your engine oil. your car runs progressively less well if your dipstick is low. for optimum performance simply keep your oil level at the dipstick full mark as it was designed, do same with vitamins/minerals. with the recent virus he does recommend upping c, d and zinc intake, but at the very least maintain a 100% rda supplement intake. it’s important to read the back label of the supplement bottle and pay a little extra to get a full 100% rda appropriate to your age and gender.
also lutein for eyes, a joint supplement (i painlessly jog with 2x6lb handweights 4mi daily), krill oil, low dose aspirin.
and try to avoid going down the big pharma, silly-named, pill path.
a few years ago i needed a cardiac evaluation. the cardiologist, after extensive testing found nothing life-threatening, but wanted to start me out on some daily silly-named pill and come back for a followup evaluation. my brother told me to throw out the written prescription, start exercising more regularly, eat/drink a little more sensibly and don’t return. it all worked, ymmv. my brother, a solo practitioner with 40 years of medicine and 25,000+ surgeries under his belt, is not a huge fan of corporate/government american medicine as it practiced today, needless to say.
