I have given myself a headache from researching this, so I'm going to pose this as a short question for you guys and then go to bed lol. I somehow came across a website called gravelproofhoof and started looking through it. They kept mentioning how adding magnesium can help hooves, so I looked at the magnesium page (link here) and the list of symptoms of deficiency surprised me!!
The ones that I think most apply to Chrome are short stride with toe first landing, standing with his front feet under him (I've noticed this in the past, but never could figure out what caused it so I assumed it was a conformation thing, but apparently it is a posture thing...), stifle catching and sweet itch. Could magnesium really help these things??? It's enough to make me want to try it. The problem is they say that magnesium chloride is the best source and I can't find a single supplement using it!! I would like to try a hoof supplement since it will have copper, zinc, biotin, etc. in it too, but if there isn't one does anyone have any idea how to find just magnesium chloride by itself? Also on the hoof supplements do they normally have calcium in them? This website says too much calcium can inhibit absorption of magnesium. Also according to them grass hay provides all of the calcium they need. So anyway this is getting longer than I intended. I can't process coherent thought anymore because I've had my nose buried in this too long, so I'm going to take a break. :) Thanks for any help!!!
P.S. Here is the page with the case study on a horse who has always been barefoot but landed toe first like Chrome and how magnesium helped him (LINK).
