my dd (17) dose not eat red meat and is heavy on the fruits and vegs. she is pretty healthy and fit. she donated blood a couple times but the last 2 times she went her iron was low and was unable to give blood. both times I had her eatting spinach and beans thinking i was keeping her iron good. what is the best way to keep her iron up?
she dose take a teen vitamin but nothing else. should she be taking an iron supplement...or is there food besides red meat that is really good for iron intake????? our gp said just a teen vitamin should work but it isn't. so any info would be appreciated and very helpful to mom and dd. Thanks a bunch .Ill check back later.
Peace
