Advice on Calming products?

[One & a Million & 2]

Hi All,
I'm looking to buy a calmer to help relax my mare and help her concentrate and not find the world as spooky, but there are so many on the market, I would like to ask your advice on what brands, ingredients you think would help the best and what you have found to be the better product on experience?
Many Thanks in advance.

You would do better asking this in the horse care section of the forum more people will see it there. I have never needed to use a calmer but I use Feedmark products for arthritis and I am happy with those, they make a calmer too. My friend had a stressy horse and used magnesium I have no idea where she bought it from though.
