I would recommend 365 Complete from Equine Answers. It is fantastic and is more concentrate than many others better known brands on the market. Well worth a look
Pink Powder is fab, and 2nd choice is always Equivite, but the Pink Powder is good as it has probiotics in which is also good for a stressy type of horse!
Thank you for all your recommendations, will have a look at the equivite as my boy doesn't need anymore condition, we are trying to lose it as with the recent rain and my bad back he has ballooned again and is on a serious diet and exercise program!!!
I use feedmarks Benevit and all mine have never looked better, their coats look amazing as well, they are also really good at sending things next day and having offers on so you can buy a massive tub half price sometimes and its lasts quite a long time
Benevit is good &, as already mentioned, you can get some good deals on it. However not all horses find it palatable which may be tricky if you're only giving a token feed. I'm another one who uses Equivite.
Another long term Feedmark Benevit user here. A really good spec and excellent value for money when bought on the half price offer (which I always take advantage of). I've never had a horse turn it's nose up at eating it, but mine do get nice big feeds !!
