I recently put my horse on Smartbreathe for a seasonal cough he seems to develop this time of year. Other years I tried other cough products which did nothing for him but so far this one seems to be working. I noticed the main difference in ingredients is Quercetin. So, I did some research on this ingredient and find that many feel it is very effective in relieving respiratory inflammation/irritation.
I started looking for other products which contain this ingredient and did find several. I want to switch because the Smartbreathe contains curcumin which can cause GI upset (which my horse is prone to).
I just ordered an immune booster called U Balance from Uckele and it contains a slightly higher amount of the Quercetin than Smartbreathe has and does not have the curcumin so I am hoping it will be as effective but without the GI concern.
I just wanted to share this info with others since I know there are lots of horses who deal with COPD/Heaves and seasonal allergies.
