Your horse tested positive for P5, P6, or both -- now what? This 6-page starter diet template was created by Stephanie Carter, FNTP, IHP, author of Managing Muscle Mayhem and Equine Functional Nutrition, to help you take the first step toward supporting your P5/P6 horse through species-appropriate, functional nutrition.
 
P5 and P6 are the most enigmatic of the MIM variants. Scientists can detect them through genetic testing, but the specific gene and protein involved have not yet been identified. Unlike the dominant variants, P5 and P6 are recessive, meaning a horse typically needs two damaged copies before symptoms appear. A horse carrying one copy can appear completely normal, making these variants particularly challenging to identify without testing. This template takes a broad-spectrum nutritional approach designed to cover all possible pathways while research continues.
 
What's included:
Plain-language explanation of what is currently known about P5 and P6, including their recessive nature and compound heterozygote considerations
Key dietary principles for managing variants with unknown mechanisms
Twice-daily feeding chart with serving ranges based on an 1,100 lb horse (scalable by body weight)
Region-specific product recommendations for the US, Canada, UK/Ireland, EU, and Australia/NZ
4-week transition schedule for safe diet changeover
Label-reading quick reference to identify ingredients to avoid
Important transition notes including detox expectations and guidance on staying current as research evolves
 
This template is designed for P5/P6 horses. If your horse carries additional variants, has metabolic challenges, or is not responding after 8-12 weeks, a personalized nutrition consultation is recommended at stephaniecarterntp.com.
