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.
