Can Fifteen Plus be used every day for an older horse?
Absolutely. The product is designed to be fed continuously to support the older horse.
Can Fifteen Plus be used instead of Gut Balancer?
Fifteen Plus has less probiotic than Gut Balancer but is enough for most seniors. Horses needing more can get half a dose of Gut Balancer. Both contain the same Preplex prebiotics.
Can Fifteen Plus be used instead of Acid Ease for my older horse?
Acid Ease has ingredients to calm excess acid not in Fifteen Plus. For extra stomach support, use Acid Ease alongside Fifteen Plus.
Fifteen Plus supports joints. Can it be used instead of Cosequin Equine or other joint support products?
Fifteen Plus supports joints with glucosamine, curcumin, and omega-3s, enough for most seniors. Hard-working horses may benefit from Cosequin Equine, a stronger formula with high levels of Glucosamine HCl and Chondroitin Sulphate.
Can Fifteen Plus be given to horses prone to laminitis?
Yes, Fifteen Plus is suitable for horses with laminitis.
