Customer Reviews
Detailed experience with Custom Premix
My recent order was for a Custom Premix after using their Diet Balancing Services. The process was quite thorough. I uploaded my hay analysis results, and their team provided a detailed report and recommended a custom blend. Ordering the premix was straightforward on the website. It shipped from Canada and arrived in New York in about a week. The packaging was robust, and the supplement clearly labeled. My horse seems to be thriving, and I appreciate the scientific approach. The customer service team was also helpful when I had a question about dosage. It's a bit more involved than just buying an off-the-shelf product, but the personalized approach was worth it for my specific needs.
Good quality, minor shipping hiccup
I ordered the W-3 Oil and some Magnesium Oxide. The product quality seems excellent, and my mare is doing well on them. The packaging was secure. My only minor issue was that it took 5 days to reach Denver, which was a bit longer than I expected, but still acceptable. Overall, good value for the money, and I'd consider ordering again.
Omneity is amazing!
I can't say enough good things about Mad Barn and their Omneity supplement! My horse looks and feels fantastic since starting on it. Shipping was fast to California, and everything arrived perfectly. I'm definitely shopping here again and telling all my barn friends about them!
Probiotics worked well
Decided to try their Probiotics for my horse who sometimes gets a bit gassy. Ordered it last week, and it showed up pretty quick. My horse seems to be doing better, less bubbly in the stomach. The bag is a good size too. Pretty happy with it.
Reliable for Gastric Health
This isn't my first time ordering from Mad Barn. I've consistently bought their Visceral supplement for my sensitive gelding, and it always helps keep him comfortable. This order was just as smooth as previous ones. The website is easy to navigate, and shipping always gets here to Pennsylvania within a week. I keep coming back because I know I can count on the product and the service.
Quick delivery, good product
Got the Biotin for my horse's hooves. Shipping was fast to my farm in Texas. Product arrived quickly. Horse is eating it fine. No complaints.
Mad Barn Community Discussion
Share tips, ask questions & help fellow shoppers save more
Thinking about trying their W-3 oil for my mare. Is it worth the price compared to other brands? Like, how does it stack up against Platinum Performance or SmartPak oils?
Hey guys, planning to order some Omneity. Does Mad Barn ship to California? And how long does it usually take to get here?
Heard about a Black Friday sale for Mad Barn. Is that a real thing, like do they actually do good discounts around then or is it just kinda meh?
What's their return policy like if my horse just refuses to eat the supplement? Can I send it back if it's been opened and she won't touch it?
Does anyone know if you can use like a first-time buyer discount AND free shipping if your order is over a certain amount? Or is it one or the other?
