Psyllium Pellets


Formula 707 Psyllium pellets can help eliminate sand and dirt from the digestive system. Grazing on short pastures can lead to horses ingesting large quantities of sand, sometimes leading to sand colic. Psyllium seed husks expand and become sticky in the digestive system, helping remove built up sand and dirt from the cecum and colon. For monthly maintenance, give horses 2 oz. twice daily for three consecutive days each month to promote healthy digestion.

A Name That's Been Trusted for Over 75 Years

Today, we continue his legacy with a full line of innovative products to support every horse.
