SynOsteon and SynOsteon Maintenance

Every stride a horse takes in training puts real load on its skeleton, and the skeleton answers by remodeling itself, laying down and resorbing bone in response to work. When that conditioning outpaces the bone's ability to keep up, the result can be sore, bucked shins or a stress fracture that pulls a promising horse off the track. SynOsteon and SynOsteon Maintenance from SynNutra Equine are built around that biology: a pair of all-natural, drug-free feed supplements made to support healthy bone development, mineral balance and the remodeling process in horses asked to perform.

SynOsteon is a powdered, all-natural feed supplement formulated to help support bone development and remodeling, with particular attention to the cannon bones and shins that take the brunt of early conditioning. Rather than treating bone as a static mineral block, the formula supports the living framework underneath it. Silicon helps support the collagen matrix that gives bone its flexibility, while menaquinone (vitamin K2) and beta-glucans are included to support the deposition of calcium into bone. Vitamin D supports the absorption of dietary calcium, and icariins from Herba epimedii are included to support balanced bone-building activity. The label pairs these with meaningful levels of calcium and magnesium so the raw minerals are present alongside the cofactors that help put them to work.

How is SynOsteon Maintenance different from the loading formula?

Think of the Syn Osteon line as covering two phases of a horse's working life. The first phase is intensive support, when a young horse is just starting under saddle, when a horse is coming back after more than a month out of training, or when a vet is managing bucked shins or a stress fracture and wants nutritional support during the healing window. SynOsteon Maintenance addresses the second phase: routine, ongoing support for the bones, tendons and ligaments of an active horse that is already conditioned and racing. It is intended as part of a daily wellness program, keeping a steady baseline of bone-supporting nutrients in the ration once the heavy lifting of early bone building is behind you. Both products work through the same drug-free ingredient profile; the difference is when and how long you reach for each one.

How do you feed SynOsteon to your horse?

SynOsteon is built for the feed room. It comes as a convenient powder that you mix into your horse's daily feed, following the serving guidance on the packaging. For a young horse in early training, the maker's guidance is to supplement daily through the conditioning period, continuing until the horse is fit enough to race at full distance. For horses returning from an extended layoff, or those a veterinarian is managing for bucked shins or stress fractures, SynOsteon is fed during the period of bone development or fracture healing, with the dose and duration discussed alongside your vet. Because it is all-natural with no drugs or banned substances, there are no withdrawal times to plan around, though as with any supplement it is intended for equine use only and not for pregnant or lactating mares.

Who is behind SynNutra Equine?

SynOsteon comes out of SynNutra Equine, a company founded by practicing equine veterinarian Dr. Edwin Simpson, DVM, whose career spans decades in thoroughbred racing. SynNutra's approach blends Western scientific rigor with holistic, integrative thinking, leaning on guidance from scientists, pharmacologists and herbologists to build supplements around specific performance-related problems rather than generic wellness claims. Every product is veterinarian-formulated and tested, made in the USA, and carries the NASC Quality Seal, with the company drawing on outside laboratory testing for consistency. The throughline is a drug-free philosophy: support the horse's own biology with natural, field-tested ingredients instead of pharmaceuticals.
