I supplement with antioxidants. It has been a game changer in all aspects. The kind I use is NRF2. Let me know if you would like more information.
For my horse I love putting together carrots, apples, bananas (put the veggies your horse loves) and add some honey! I don't give him that too often as there's a lot of sugar but of course he loves it.
For me it's quite the same aha, I love have a greek yogurt with honey and fruits.
I also often make these kind of cookies but in a healthy way by mixing a banana with oat and chocolate chips, I put the cookies in the oven for like 15min and it's ready!
