UltraCruz® Equine Lysine (Pure), 25 lb

This equine lysine supplement has been an absolute standout in our program. Within just a few weeks, I noticed a visible difference—improved topline, better muscle development, and an overall healthier, more balanced look. It's made a huge impact, especially for horses that need a little extra support maintaining condition. One of the best parts is how easy it is to feed. No strong odor, no refusals—my horses eat it right along with their grain without hesitation. It mixes in seamlessly and feels like a simple upgrade to their daily routine with big results. What really impressed me was how much it helped one of my horses after shipping. He tends to have a weaker immune system, especially following flights and long travel, and this supplement made a noticeable difference in how quickly he bounced back. He stayed brighter, kept his appetite, and seemed to recover much faster than usual. I've also seen improvements in coat quality and recovery after work, which tells me it's really supporting them from the inside out. Whether you're bringing along young horses, maintaining performance horses, or helping hard keepers, this supplement truly delivers. Highly recommend—this has become a go-to in our barn and something I won't go without!

[This review was collected as part of a promotion.] Excellent palatability for my 20 yr old gelding. He ties up and loses top line very fast. Our vet recommended I add an amino to aid our efforts to rebuild his muscles. I start everything very slowly, but he is already showing more fullness in his muscles. Always very impressed with Ultra Cruz products.

Our mules are older and metabolic, and we need to watch insulin/sugar in feed, so they are on grass hays exclusively. Because of this they need Lysine added to their diet. This product is easy to feed and they love it.

[This review was collected as part of a promotion.] We use UltraCruz Lysine to supplement our whole nutritional plan for our therapy herd—it allows us to provide the highest quality product for what our horses need, but without bulk of adding more feed. We went through a year when we could not get a nutrient-dense feed in our area due to issues with mills, and UltraCruz Lysine allowed us to make sure our horses got what they needed to maintain their senior health and happiness!

[This review was collected as part of a promotion.] A great product, horses eat it and it helps their immune system.

[This review was collected as part of a promotion.] Affordable and quality product. Easy to feed and very fresh.

[This review was collected as part of a promotion.] Wanted specifically L-Lysine to add a little extra. Very affordable, & none of my picky eaters have refused it.

[This review was collected as part of a promotion.] Horses love it and working great for a weanling. Easy to feed and measure.

[This review was collected as part of a promotion.] Easy to feed, great service from Santa Cruz. I did receive one bag where it had gotten clumpy. It was extremely time consuming because each of hundreds and hundreds of clumps had to be broken up by hand and the product has an awful, chalky, metallic texture that makes you grind your teeth to have to touch… otherwise this has been great.

[This review was collected as part of a promotion.] I personally think the pelleted lysine is better than the powder and they eat it better. I will buy pelleted the next time.
