Skip the Fish.
It's Time to Look at Algae.

PhytoSmart Krumble™ delivers whole omega-3 nutrition from algae - the original source of DHA and EPA - in a clean, sprinkle-on food topper made for daily pet wellness.

The original source of Omega-3's DHA and EPA is marine micro-algae and NOT fish or fish oil.

Looking for Fish oil for your pets? Start where the fish start - with micro-algae!

For years, fish oil has been the default omega-3 supplement for dogs and cats. Pet parents hear about it for skin, coat, joint, heart, immune, and cognitive support — and they naturally search for what they know.

But fish oil is only one way to deliver omega-3s.

The nutrients people are really looking for are DHA and EPA, two important omega-3 fatty acids that support healthy function throughout the body. Fish accumulate these omega-3s through the food chain. Algae is where they begin.

Whole algae. Nothing extracted. Nothing unnecessary.

PhytoSmart Krumble is not a fish oil, capsule, or concentrated oil. It is a functional food topper made from whole-cell algae grown and preserved with care.

Instead of extracting oils and isolating nutrients, PhytoSmart keeps the algae intact — preserving omega-3s within their natural food matrix. That means your pet gets DHA and EPA in a simple daily format that fits right into mealtime.

For cats with medical conditions, allergies, pancreatitis history, kidney disease, or prescription diets, consult your veterinarian before adding new supplements.

Fish oil is processed, concentrated, and stripped of the whole-food nutrition that makes omega-3s actually work in the body. At PhytoSmart, we grow and harvest marine microalgae the original source of the essential omega-3s all mammals require and deliver them with an intact phospholipid structure that your pet’s body absorbs and uses far more effectively than fish oil ever can.

Fish oil was always a cheap un-sustainable shortcut-we went back to where omega-3s originate from, what the fish eat to get the omega-3’s. Now your pet gets what every mammal was meant to have – whole food DHA and EPA without ocean contaminants, without destructive fishing practices, without synthetic preservatives. Clean whole food nutrition.

Support skin, coat, mobility, brain, and everyday wellness.

Omega-3s are essential nutrients involved in many normal body functions. Pet parents often explore omega-3s when they want to support:
