Performance notes
As a powder additive, it's meant to be sprinkled into existing kibble or wet food rather than fed on its own, which works well for households already committed to a base diet who want to add general wellness support. Kelp based formulas like this one are commonly chosen for coat shine alongside digestive and immune support.
