More and more pet owners are realising that this humble single-celled plant can make a tremendous difference to their dog’s wellbeing, and especially when battling certain serious health conditions.

Interestingly, dog owners have been the pioneers in some ways, contacting us more frequently in the early days than humans about the possibilities of this miraculous green powder.

We believe this simple marine organism is the healthiest broad-spectrum green supplement for any pet, and we have seen it working on profound levels with our own animals.

Mix in a gram or two with their food, and you’ll see immense benefits to their skin and fur, their eyes’ shine, and even their breath’s freshness.

We’ve heard promising reports, too, from people whose dogs are battling some tricky healthy conditions, so we’re entirely confident that this is something which is highly beneficial to pets.

This article will explore the benefits of marine phytoplankton for dogs and how to use it safely and effectively. Whether you’re looking to support your dog’s joint health, boost their immune system, or improve their skin and coat, marine phytoplankton may be the natural solution you’ve been searching for.


Marine Phytoplankton offers certain distinct benefits to other health supplements for dogs, principally its

  • breadth of nutrients

10 Reasons Your Dog Needs Phytoplankton

#1 Great for Your Dogs Joint Health

The high levels of long-chain EPA make this a winning supplement for joint health, and many people with ageing dogs have noted heartening results. Marine phytoplankton also contains glucosamine and chondroitin, which help to support joint health and reduce inflammation, making it an excellent supplement for senior dogs.

#2 Cardiovascular Health

With the poor quality of many commercial foods and lack of exercise, many people find their dogs have heart issues of various sorts. Again, phytoplankton is a brilliant addition here, offering easily absorbable micronutrients which, combined with the power of EPA, appear to strengthen cardiovascular function within a matter of days.

#3 Improves Eyesight

Phytoplankton has a superb effect on eyesight, sharpening and clarifying vision, especially in cases where vision is being effected by an overburdened liver.

#4 Improves digestion

Marine phytoplankton is also rich in enzymes and probiotics, which can improve digestion and alleviate digestive issues such as bloating, gas, and diarrhoea.

#5 Great for Soft Tissue Inflammation

We have to be careful about making any claims for the ability of phytoplankton to help dogs with cancer. All we can say is that we have heard that people have found the powder has been highly beneficial as a supporting element in their dog’s health journey. It is highly absorbable in a way which crosses the blood brain barrier. It contains more superoxide dismutase (SOD) than any other supplement, and since this is a primary antioxidant generally killed by stomach acid, it is ground-breaking. SOD has already been used successfully for soft tissue inflammation in both canine and equine veterinary situations so there’s mounting evidence that it has beneficial properties.

#6 Helps Maintain a Shiny Coat

The high bioavailable oil and nutrients in phytoplankton make it a superb addition to any dietary regime for your dog, and we’re confident you’ll notice a real shine to their coats soon after doing this. The high levels of omega-3 fatty acids found in marine phytoplankton also help reduce the risk of skin allergies and irritations.

#7 Benefits Dogs with Diabetes

More and more pet owners report that marine phytoplankton has helped their dog’s canine diabetes. In fact this is one of the fastest-growing areas of the business since this is a notoriously difficult condition to treat without pharmaceuticals. It may be doing this because of its general immune-boosting properties because it helps detoxify the pancreas, or because the phytoplankton has blood-sugar balancing properties. In both Type 1 and Type 2 diabetes, there is evidence of liver inflammation, and here plankton really shines. With its powerful antioxidant and anti-inflammatory properties, plankton helps takes dogs back to a state of balanced health, offering broad-spectrum minerals and helping restore normal glucose levels over time. There’s a lot of evidence that essential fatty acids play a role in alleviating diabetes, too so, in our view, plankton should be a part of any canine health regime. Please write and tell us of your experiences with this!

#8 Supports Pet Allergies

Perhaps because of its immune-modulating effects, plankton seems to aid dogs facing allergic reactions in boosting overall health, reducing inflammation and restoring the system to integrity and wellness.

#9 Supports Dogs with Cancer

One of the most common reasons we’re contacted about canine uses regards cancer. The web is full of extremely strong claims about how phytoplankton can help with cancer, with little scientific evidence backing this up as yet. Our suggestion is that you simply try it and see how it works for your pet – it’ll certainly offer broad-spectrum vitamins and minerals which can be easily absorbed, as well as a powerful energy booster. There is evidence to suggest the antioxidants in phytoplankton are powerfully anti-carcinogenic – hopefully, as more studies are conducted, we’ll be able to publish some of them here.

#10 Supports Immune System Function

Packed with superoxide dismutase, minerals, vitamins, carotenoids and EFA’s, this green powder offers phenomenal broad-spectrum immune system benefits.

How to Use Marine Phytoplankton for Dogs

Here are some tips on how to use marine phytoplankton for dogs:

  1. Choose Phytality: Phytality is a very different supplement than most competitors. From algal strain choices through to growing conditions and sustainability, every effort is made to ensure it’s the purest, most potent phytoplankton on the market.
  2. Follow dosage instructions: Dosage instructions may vary depending on the size of your dog. (see more below)
  3. Mix with food or water: Marine phytoplankton can be easily mixed with your dog’s food or water. If using a powder or liquid form, mix it in with their food or water as directed.
  4. Start with a small dose: When introducing marine phytoplankton to your dog, start with a small dose and gradually increase it over time to avoid any digestive upset.
  5. Be consistent: Using marine phytoplankton consistently and as directed is important for best results. Regular use can provide maximum benefits to your dog’s health and well-being.
  6. Monitor for side effects: While marine phytoplankton is generally safe for dogs, some dogs may experience mild side effects such as diarrhoea, vomiting, or lethargy. If your dog experiences these symptoms, stop using the supplement and consult your veterinarian.

How Much Marine Phytoplankton To Give Dogs

It’s unlikely there’s any more nutritious substance you can give your dog. As such, you don’t need to feed them much, and it’s by no means an exact science.

We’ve listed some guidelines below based on how we feed our dogs. Feel free to adjust based on your dogs taste buds, health condition, and enthusiasm for the product.

  • Small Dog = 1 Gram ( 1/2 teaspoon) per day
  • Medium Dog = 2 Grams per day
  • Large Dog = 3 Grams per day

Is it Better Than Fish Oil?

While phytoplankton is the richest plant source of Omega 3 oil, the comparisons to fish oil are not necessarily appropriate.

It would be impractical to ingest enough phytoplankton to match a spoonful of pure fish oil’s quantity of EPA, so if you’re giving your dog fish oil for joint health or some other highly specific reason, we don’t suggest changing it.

Phytoplankton offers benefits that are different. What’s most notable about how it seems to affect animals is that it somehow delivers nutrients while others fail. Somehow, because of its tiny cell size and extraordinary diversity of micronutrients, it seems to make it through the digestive systems of even pets with tremendously compromised digestive tracts.

This may be why we get testimonial after testimonial recounting dogs who have responded near miraculously from adding phytoplankton to their diets. It seems to deliver vitality and health in almost every case.

Are there Side Effects to Giving Marine Phytoplankton to Your Dog?

In some cases, animals with an overburdened immune system may feel a bit under the weather for a few days as the body is suddenly flooded with nutrition and a healing reaction occurs.

In rare cases, their bowel movements become slightly looser (or even green if you’re giving a good amount), but this passes.

Overall, we can say this natural wholefood product really has minimal side effects and, in thousands of sales, we’ve had wonderful reviews and positive responses.
