Welcome to TCX Supplements!

Dr. Steven Smith - TCX Supplements

Welcome to TCX Supplements!  2025 was a huge year for us, culminating with the launch of our website and online store.  It has been an enormous amount of work to get this far, but we are incredibly excited for our great products to finally be available to horse owners all across Canada.  Our flagship product TCX Performance can now be purchased directly from our website (as well as from Veterinarians across the country), and additional products will soon follow, including our elite, highly absorbable electrolyte concentrate TCX lyte. 

TCX Performance was available to a small amount of clients for the summer months to allow us to test the product in a real world setting.  10 horses with various jobs were put on TCX Performance for 30 days, with a complete blood drawn on day 1/15/30.  Muscle enzyme counts in 9 of the 10 test subjects decreased from day 1 to day 30.  A survey was conducted with the owners of the test subjects responding that all horses ate the product with no issue.  8 of 10 owners reported a decrease in back sensitivity in their horses as well as 7 out of 10 reporting an improvement in their horses performance. Two of our test subjects at the racetrack were highly successful in their racing season; Attack won the Manitoba Derby after 2 weeks on TCX Performance and Hiway Fortynine was a two time 50k stakes winner. 

TCX Performance is an all natural drug free tart cherry/BCAA supplement designed to support muscle performance and recovery, reduce muscle and joint pain, and enhance athletic performance.  Tart cherry has numerous other health benefits which can help your horse reach it’s highest level of performance.  It is available as a highly palatable powder in a 600gram jar (30-60 day supply) which can be top dressed on your horses feed. 

TCX Supplements is a family owned Canadian company that researches, develops, manufactures and brings to market premium, all natural performance horse supplements, founded by Dr Steven D Smith DVM in Edmonton Alberta.

We are looking forward to helping your equine athlete reach their highest level!
