I've read the same for older men. Copper too. And I've read that iron interferes with the absorption of...a B vitamin?
I recall the conversation with a research physician. He described that the lower rate of cardiovascular morbidity/mortality in women of child-bearing age may actually be due to monthly blood loss during menstruation, which results in the concurrent loss of iron. His argument was compelling enough that I’ve been taking “Silver” multi-vitamins for more than 25 years. Senior vitamins don’t have iron supplement.
I eat a fair amount of wild-caught fish .... Gotta have my mercury.
Yellow-fin tuna tonight.....Mmmmmmmmmmmmmmmmmmmmmmmmm-e-r-c-u-r-y!!!
Iron has a tendency to accumulate in your body in the liver and too much of that will poison you to death.
There is anecdotal evidence to this. Arctic & Antarctic explorers have died from eating sled dog’s livers from iron poisoning. As we all know liver is the best source of iron.
I have noticed my multi-vites do not contain any iron, lately. And I do not take those more than once or twice a week.
The single most important thing to enhance longevity is exercise & activity. After that comes good nutrition via food and drink. After that is a one shot of gin/brandy/whiskey/vodka in a day. Last is artificial supplements.
