What seaweed can do

At House of Seaweed, we are forever in awe of the versatility and miraculous properties of nature’s best kept secret. Is there anything seaweed can’t do?

Health & Nutrition

Seaweed is the nutritional powerhouse of the ocean, offering an incredible array of health benefits, thanks to its high content of essential vitamins and minerals. Seaweed provides a concentrated source of iodine, which is crucial for thyroid function and metabolism. It's also abundant in calcium, iron, and magnesium - vital for bone health and overall well-being.
It doesn’t stop there. With low calories, low sodium, and high fibre content, seaweed can also support digestive health, aids weight management, and may help regulate blood sugar levels.
Incorporating this superfood into products, dishes, or ingredients can be a transformative step towards an improved, nutrient-dense diet, and an easy pathway to a healthy lifestyle.

Functional Food

Seaweed has lots of functional properties too. It has gelling abilities as an alginate, but also has the highest concentration of naturally occurring umami in any food ingredient on the planet. It lends itself as a salt substitution through low sodium, mineral-based salty flavour, as well as featuring with growing regularity as a protein provider in the plant-based meat substitute market.

Seaweed contains bioactive compounds that lend themselves to numerous pharmaceutical applications. Seaweed extracts are studied for their antimicrobial, antiviral, and anti-inflammatory properties. They may also have potential uses in drug delivery systems.

Cosmetics and Skincare

Thanks to seaweed’s rich mineral content and natural hydrating properties, it’s used in face masks, serums, and lotions to nourish the skin, improve texture, and promote a healthy complexion.


Agriculture and Fertilisers

Seaweed extracts are used as natural fertilisers and soil conditioners. They enrich the soil with essential nutrients, improve plant growth, enhance crop resistance to stress, and contribute to sustainable farming practices.

Bioplastics and Packaging

Seaweed-based biopolymers offer an eco-friendly alternative to conventional plastics. They are biodegradable which means they help reduce plastic pollution and contribute to a more sustainable and ethical packaging industry.

Biofuel Production

Seaweed is a promising feedstock for biofuel production due to its high growth rate and potential for converting its biomass into bioethanol and other renewable energy sources. It can contribute to sustainable and clean energy solutions, and help to restore and rehabilitate polluted aquatic environments.

Animal Nutrition/Feedstock

Seaweed can be used as a sustainable and nutritious feed for livestock. It’s a far greener way to enhances animal health and growth compared to traditional feed sources. Research has proven that the use of red seaweeds in cattle feed can significantly reduce methane emissions.
