Supplement for a bolshy mare

Which is the best supplement for a highly seasonal mare?

Kizzy is alpha mare in a mixed field (TBH in any field she is boss). She is obliging enough most of the time but totally opinionated when her hormones kick in. She epitomises ask a mare. Saying that she has been so sweet over this winter and has had no signs of being in season. Apart from mud/ice/wind/dark nights/freezing weather I wish it could continue!

Never been so far as to look for a feed balancer but am now very interested.

Many thanks for input!
 
Oestress, FriskyMare (Global Herbs), MoodyMare are three options that have good opinions - I think its dependant on the horse what they respond better to
