On the Red Cross website they had a blurb that considered 3 or more donations for a male considered "frequent". They recommended frequent donors take iron supplements.
It's smart that you monitor your own bloods.
Got to, i don't have a doctor and i blast and cruise. I get lipids and everything else a couple times a year and then just standard bloods a couple times a year. The full iron count was only like $50 extra. Definitely worth a look if you donate often. Best to go about this lifestyle as safely as possible.
