Omega-3 DHA + EPA
algae omega-3 supplement for Cats & Dogs
PhytoSmart DHA + EPA is a fish-free algae omega-3 supplement for dogs and cats. Made from whole-cell marine microalgae, it provides DHA and EPA in a shelf-stable, sprinkle-on food topper designed to support everyday nutrition and overall wellness.




Our whole-cell marine microalgae is grown and harvested in Maine, USA, using a patented, heat-free cultivation system designed to preserve its natural nutrient profile. The omega-3s remain within the algae’s natural food matrix rather than being extracted into an oil.
The shelf-stable, sprinkle-on format requires no refrigeration and stores easily in a cool, dry place. Simply add the recommended serving to your pet’s regular meal or offer a small amount on its own.
Compared with traditional liquid omega-3 oils, PhytoSmart is easy to measure and serve without pumps, spills, or oily residue.
