LOVE SMARTPAKS!! They offer a large variety and reviews on all their stuff as well as the contents of each supplement are there to read. I have used a variety of their products, and probably spend far too much now that Im up to 4 horses but its been worth it. I have a easy keeper so he can't eat alot of grain, and his supplements ensure that he stays healthy. I have my mare on their Smart MSM which really helped her past hock injury which showed stiffness especially in the winter time. Since a recent move and the fact the prior owners at our new place were not big on fly/manure control...I put them all on the smart bugoff, and its wonderful. Between the fly predators I got started at our new place and the bug off my horses are doing so much better, and flies are down by more than half. It will be even better next year since it will take me that long to get everything as I like it. I also had my mare on smart hoof when she foundered 2 years ago, it did amazing things for her hoof growth (along with my vet and farrier) and she has totally recovered. I've also tried the smartomega 3 from smartpak, had my two geldings on that until I switched to the bugoff which already has omegas in it. And smartpaks customer service is exceptional. If a supplement didnt work they were more than happy to refund my money and help me find something else. I would even get phone calls afterwards to see how that paticular horse was doing. I know when my neighbors mare passed (per my recommendation he had her on a smartpak) and he called to cancel, they refunded his last order he received and sent him a sympathy card. Also if you pay attention, they are always sending coupons you can apply towards your smartpaks. I also have started ordering my wormer thru them since shipping is free with my smartpaks, so I just add it to my order every other month. I have found they are just as cheap, if not cheaper as going to my local feed store or TSC.
Unfortunately, the only way our BO will do supplements, other than MSM, is in SmartPaks since she and her workers are the ones that do the feeding. SmartPak is easy for them to just open and add to the feed bucket...so I guess I am paying for convenience as well. If I had Izzy at home, I would definitely find a way to do it cheaper.
A lot of people at my barn create their own "smart paks" in Ziploc baggies. Just mix up the supplements they want and seal the bag. Barn manager just opens the bag and dumps.
I love SmartPak supplements! I use SmartFlex Senior, and it does wonders for my boy. I love the smell of the SmartFlex when I open the bucket. It smells so yummy! And my boy gobbles it up!
Their customer service is awesome too! They call me every few months to see how me and my horse are doing and if I have any questions or concerns. And whenever I've had to call them, I'm not having to wait and wait and wait for a customer service rep to take my call. I'm thinking I might order some SmartVitefor both my horses, since one is on grass hay and the other is on alfalfa. Great company, awesome concept! Wish I could work for them over here on the west coast.
