Frequently Asked Questions

Krumble™ has an 18 month shelf life when unopened. Once the package has been opened please use it within one year. Store in a cool dry place (or refrigerate) with the lid tightly closed and snapped into places after each use.

PhytoSmart™ previously offered a DHA Paste as a fresh, cold‑shipped format, but it is not currently being produced while a new, easier‑to‑serve packaging option is developed. The PhytoSmart™ DHA Paste is expected to be available again sometime in the summer of 2026, while PhytoSmart Krumble™ remains the convenient, shelf‑stable whole‑cell algae in a dry flake format for daily use.

Krumble™ is shelf stable and should be stored in a cool, dry place with the lid closed tightly and excess air gently pressed out of the pouch or bottle after each use. Keep it away from heat, moisture, and direct sunlight to help preserve the natural oils and antioxidants in the whole‑cell algae and broccoli sprouts.

Yes, both PhytoSmart™ Omega and Krumble™ are grown, harvested and packaged at our facility in Brunswick, Maine.

Marine microalgae are the original source of DHA and EPA in the marine food chain, delivering these fatty acids without relying on fish. Algae‑based omega‑3s avoid common marine contaminants, reduce oxidation and fishy odor, and offer a more sustainable, direct source of DHA/EPA for pets.

PhytoSmart uses unextracted, unaltered whole‑cell algae, preserving naturally occurring omega‑3s, enzymes, and cofactors, and it is grown in a controlled, heat‑free system in Maine to maintain enzyme activity and limit oxidation. The addition of freeze‑dried broccoli sprouts supplies sulforaphane and its precursor glucoraphanin, compounds studied for their roles in detoxification, cellular protection, and potential cancer‑risk modulation.

Omega‑3s from algae help regulate inflammation and support joint comfort, cardiovascular health, skin and coat quality, and brain function. Sulforaphane from broccoli sprouts activates cellular antioxidant and detox pathways that support gut barrier function, immune resilience, and cellular defense. Many pet parents notice softer coats and better comfort within a few weeks, while deeper benefits such as joint mobility, cognitive support, or allergy and gut changes may take 6–12 weeks of daily use.

DHA and EPA are precursors to resolvins and protectins, molecules that actively help switch off inflammation and support pets with skin allergies, arthritis, and inflammatory gut problems. Sulforaphane‑rich broccoli sprouts further support the gut microbiome, barrier integrity, liver detox pathways, and antioxidant defenses, making “Cell‑abrate Health” especially relevant for chronic conditions, allergic and sensitive pets, alongside appropriate veterinary care.

Many pets enjoy the mild, non‑fishy flavor of the algae flakes, especially when introduced gradually. For sensitive eaters, start with a very small amount, offer some PhytoSmart from your hand or on an empty dish, then build up over several days; we offer the DHA formula & the “Cell-abrate Health” formula, in a 20-gram trial size option. If you are unsure of how your pet will respond to PhytoSmart we, recommend starting with either of the 2 products in the 20-gram trial size option before purchasing the full size products.

Krumble™ is a lightweight, shelf‑stable flake you simply sprinkle on your pet’s food or offer alone as a topper or treat. Since PhytoSmart Krumble™ is a whole food, you can safely use the full amount within your pet’s weight range once they are accustomed to it, and you may split the daily serving between meals.

For most pets, start with about half the suggested daily amount for 3–5 days, then increase to the full serving so their taste and digestion can adjust gradually.

Standard daily servings (by weight, using a measuring teaspoon):

• Pets up to 20 lbs.: ¼ teaspoon per day
• Pets 20–50 lbs.: ½ teaspoon per day
• Pets 50–90 lbs.: ¾ teaspoon per day
• Pets 90+ lbs.: 1 teaspoon per day

Depending on how you shake it use the following guidelines when dosing your pet using the shaker top option:

• Pets up to 20 lbs.: 2–8 shakes per day
• Pets 20–40 lbs.: 4–12 shakes per day
• Pets 40–80 lbs.: 8–16 shakes per day
• Pets 80+ lbs.: 12–20 shakes per day

You can adjust slightly up or down based on your pet’s body weight and response over time and always follow your veterinarian’s guidance if your pet has a medical condition or is on medications.

Krumble™ DHA focuses on brain, eye, skin, coat, and senior cognitive support, and is a fishfree alternative for pets needing targeted DHA; We have found that cats often prefer our original DHA formula, which is a great in helping reduce or eliminate hairballs. Krumble™ DHA & EPA provides broader omega3 support for joints, heart, skin, coat, kidney health, allergy relief and immune balance. PhytoSmart “Cellabrate Health” combines wholecell DHA algae with broccoli sprouts for antioxidant, cellular, liver, immune, and detox support – excellent option for pets diagnosed with cancer .

For general health maintenance, rotating or alternating among the three formulas over time is an excellent strategy.

For skin and coat health, brain and vision support, and senior mental sharpness, choose Krumble™ DHA (ideal starting point for picky cats). For stiff joints, heart health, skin issues, or general inflammation, choose Krumble™ DHA & EPA. For allergies, toxin exposure, chronic inflammation, liver support, or overall resilience, add or choose “Cellabrate Health” for sulforaphanedriven antioxidant and gut/immune support.

An enzyme is a protein that causes a chemical reaction to occur in the body.

When enzymes are exposed to high temperatures, as they are during the manufacturing of omega-3 extracted oils, they become denatured (destroyed). This leaves extracted oils highly prone to damaging oxidation, often turning them rancid and toxic to pets.

PhytoSmart™ Paste and Krumble™ are produced in a strict temperature controlled environment designed to maintain enzyme function. PhytoSmart™ products preserve the omega-3 producing enzymes and the enzymes that protect omega-3s from toxic oxidation.

Omega-3 fatty acids are essential for good health, to support circulation, mobility, skin and coat health as well as help reduce inflammation caused by allergies, intolerances and stressors. Omega-3 DHA in particular, is a building block for brain development and critical for optimal cognitive function.

Animals and humans rely largely on their diets to ensure these important nutrients are present in their bodies. Unfortunately, these nutrients are often lacking in modern diets.

PhytoSmart Krumble™ products use food‑grade, whole‑cell marine microalgae and freeze‑dried broccoli sprouts. All ingredients are human grade and non‑GMO. They are appropriate for dogs, cats, birds, and many small animals when used as directed because they provide naturally occurring DHA (and EPA in the DHA & EPA formula) at physiologic, not megadose, levels.

Extracted omega-3 oils, such as fish, krill, and algae are highly prone to oxidation, when oxidized these extracted essential fatty acids (EFA) become toxic. Once your pet consumes oxidized extracted oils, whether in liquid, powder or dried form, harmful free radicals enter their body and can penetrate and damage a variety of cell membranes. Although omega-3 oil producers add tocopherols (synthetic Vitamin E that provides little added protection) as a preservative antioxidant, once the tocopherol molecules become oxidized, they cease to protect the EFAs.

The expiration date on extracted omega-3 oils offers protection from oxidation only as long as the package seal remains unbroken. Once the contents of the package are exposed to air, the clock starts ticking for the damaging oxidation chain reaction to begin.

PhytoSmart’s comprehensive microalgal omega-3 nutrition is derived from whole algae cells. Our patented sterile production process preserves the algaes natural protective enzymes that are critical in mitigating oxidation by catalyzing specific chemical reactions which either directly neutralize reactive oxygen species or indirectly hinder the formation and progression of oxidative chain reactions. Coupled with oxygen barrier packaging, PhytoSmart™ provides safe, superior, bioavailable, vegan essential fatty acid nutrition for pets.

Yes. DHA is crucial for developing brains and eyes in puppies and kittens, and it also helps support memory and cognitive function in aging pets. The “Cell‑abrate” blend adds sulforaphane‑rich broccoli sprouts, which help protect cells and support detox and immune function at every life stage.

Your vet is right! Omega-3s are essential for heart, joint, and brain health. Most people turn to fish oil, but that can come with heavy metals, rancidity, and often digestive issues. PhytoSmart provides those “imperative” fatty acids directly from the source (algae), offering a clean and sustainable whole-food option that is easier to absorb and not aggravating to your pet’s digestive system.

We call this “supplement fatigue,” and we get it! PhytoSmart is an essential and foundational nutrient and not just another “add-on”. Think of it as a primary building block rather than a specialized “add on”. Because our Omega-3s are unextracted (unprocessed), whole-food algae it makes them highly bioavailable, they often work more efficiently than concentrated fish oils, potentially allowing you to simplify your pet’s routine.

If your pet is dealing with itchy skin, stiff joints, or confusion and anxiety as they age, they likely need a high-quality Omega-3. While many kibbles claim to have Omega-3s, the heat-processing of pet food often destroys their benefits. PhytoSmart fills that nutritional gap with a fresh, active boost of these necessary nutrients that you’ll see reflected in their coat, energy level, eyes, cognitive health and overall functionality.

Absolutely. While we provide these resources for quick answers, we pride ourselves on being a “human-first” brand. If you’re unsure how PhytoSmart fits into your pet’s specific health plan, reach out to us. We’re here to help you navigate the confusion – no AI bots, just pet lovers and pet experts.
