Ultra-Sel Selenium & Vitamin E Formula
SPECTRA 41139 Ultra-Sel is a 64 oz liquid supplement designed for horses in low selenium areas or those needing performance-level blood selenium. It combines selenium with high-bioavailability vitamin E and MULTI-PLEX magnesium to support muscle metabolism and help prevent tying-up syndrome.
Daily Feed Integration
The supplement mixes directly into feed at a rate of 1 oz (30 ml) per 500 lbs (225 kg) body weight for maintenance. For horses in intense work, the serving doubles to twice daily, delivering sustained magnesium absorption that resists potassium interference without requiring separate magnesium sources.
14-Day Response Window
A 64 oz bottle provides approximately 64 maintenance servings for an average horse, with results expected within 14 days of consistent use. The formula targets selenium deficiency and muscle soreness but does not address caloric needs, joint support, or electrolyte replacement for heavily sweating horses.

Questions about this item
How long before the horse shows improvement from the selenium and vitamin E blend?
Expect results within 14 days when following the daily feeding directions.
What happens if the horse sweats out potassium while on this supplement all day?
The chelated organic magnesium in the Multi-Plex blend protects against potassium interference that depletes other products.
Does the 64 oz bottle include a measuring tool for the 1 oz daily dose?
The directions specify mixing 1 oz or 30 ml per 500 lbs animal weight, so a separate measuring device is required.
