Why we chose Seagreens for Australian Families

Back in 2019, we at Seaperia were doing what we had always done — providing premium seaweed nutrition for animals and plants. Our customers saw that their dogs, horses and livestock were thriving on Seaperia Meal, and they started asking us the question...
"Can I take this myself?"

We couldn't say yes — Seaperia Meal is a veterinary-grade product, formulated for animals.
But, as Australia's Seaweed Specialists, we knew what the right seaweed could do for our own health.

So we embarked on a global search. For twelve months, we researched and spoke with seaweed brands from around the world. We were looking for something rare: a product we could stand behind with the same confidence we have in our own.

Seagreens stood apart from everything else we found.

Their knowledge was extraordinary. Their quality standards were unlike anything else in the market. Their research — built over more than 20 years — was the most comprehensive we had found anywhere.

And they were a family company, with the same values and ethics that have always driven us at Seaperia.

Simon Ranger, the founder of Seagreens, flew out from the UK and stayed with us here in Far North Queensland... and a partnership was born.


That was the beginning of Seagreens in Australia.

Today, when a customer tells us their dog looks incredible and asks what seaweed could do for them... we smile, because we have the answer.

Seaweed is extraordinary nutrition for every living thing. Seagreens takes that further with 20 years of human nutrition research, the world's only nutritional seaweed certification, and a purity standard that goes beyond organic.

Seaweed - Nature’s Best Source of Iodine for Thyroid and Whole-Body Health

Seaweed is one of nature’s richest sources of iodine — a mineral essential for good health and sustained energy.

Iodine deficiency can lead to extreme tiredness, feeling cold, trouble concentrating, hair loss, and in some cases, an enlarged thyroid gland (goitre). Iodine is essential for expectant mothers and for healthy growth and brain development in children. Our bodies need iodine for strong bones, nerve function, and overall vitality.

But in Australia, we’re dealing with what we call an iodine Double Deficit which has the potential to cause iodine deficiency...

First - our ancient soils, and thus our food crops, lack iodine.
Second - chlorine used in tap water can block iodine absorption in the body.
These two factors combined mean that many Australians aren’t getting the iodine they need. [Read more here…]

For most Australians, Seagreens Food Capsules are the perfect daily supplement — carefully blended to provide the exact amount of natural iodine your body needs.

If you do have a thyroid condition or think you might be sensitive to iodine, it’s best to talk to your health professional about which Seagreens product would be best for you. Some people benefit from Seagreens Iodine Lite, while others need Iodine Plus.

You can feel confident that Seagreens proprietary blend provides organic iodine in a naturally balanced wholefood.

Supermarket Seaweed Snacks - good or bad?

Supermarket seaweed snacks are made for taste, not daily nutrition. They are rarely batch-tested for iodine, heavy metals or other contaminants such as micro-plastics, and iodine levels are often not measured or disclosed.

Add in extra salt and artificial flavours, and seaweed snacks are definitely a "sometimes" food and are best not eaten daily or even weekly.

For a real seaweed snack try our Dulse - kids and adults love the taste straight out of the pack, and because it's supplied by Seagreens it is guaranteed high quality.
