This will be a short one.
Lay magazines, and sometimes even scientific ones, have a penchant for going for the headlines when reporting on a scientific study. They can leave out important details, blow up the significance of findings, etc.. It’s a real disservice to the reader without a scientific background.
If you don’t already subscribe to this report, I highly recommend it https://equinescienceupdate.blogspot.com/ . It will be the best thing you read all month. The research is reported exactly as it was; no embellishment or sensationalizing. You can read past entries also.

Catherine,
What are you looking for exactly? Inorganic iron is absorbed by the same divalent metal transporter as zinc and copper.

Heme iron is blood, so basically no although there used to be a heme iron supplement. Horses never need supplemental iron after the age of 1 or 2. If they are anemic, there’s another cause for it.

OK thanks but I’ve receive this from a feed company regarding iron content in hay. Does it make sense? Iron in hay would be about 10% absorbable?
er: The shape of the iron determines its absorption. Heme iron (Fe2+ of iron(II) ) is well absorbed.Non-heme iron (Fe3+ of iron(III) ) is very poorly absorbed. Iron is dangerous from certain sources. Well andditch water can contain a lot of heme iron. This can lead to a fatal iron overload after years of daily use ofdrinking water with too high an iron content. Grass and alfalfa can contain a lot of iron. This is mainly non-heme iron. So very poorly absorbed. (usually only 1-10% absorbable)

Dr Kellon, do you have any article about non heme iron absorption in horses? That would be very interesting! Thanks!
