As more and more people shift towards a vegetarian or vegan lifestyle, the search for high-quality, plant-based protein grows. While some people struggle to think up exciting new recipes focused on kale, spinach or sprouts, the more savvy plant lovers have turned their attention to an often overlooked option – seaweed.
Going way beyond the traditional sushi wrap, roasted seaweed thins are a great source of protein and definitely deserve a spot at your table.
Is seaweed a good source of plant-based protein?
Seaweed is a rich source of protein and therefore a valuable addition to a veggie-based diet, without compromising on flavour. The savoury taste and satisfying crunch works to reduce those hunger pangs while supporting your daily protein intake.
Dried seaweed sheets can actually provide anywhere between 20g-30g of protein per 100g, and they have a whole range of other health benefits, too! Seaweed provides other essential nutrients like vitamin B12 (cobalamin), iodine, omega-3, iron, potassium and calcium, contributing to good thyroid function, strong teeth and bones and a boosted immune response.

Sustainable plant-based protein
Sustainability is a key concern for conscious eaters and one of the biggest advantages of seaweed – seaweed is actually good for our planet, unlike other protein sources. Seaweed grows quickly in salt water without fertilizer or harmful chemicals, making it one of the most sustainable proteins available.
Seaweed farming helps to improve ocean eco-systems by absorbing excess carbon dioxide and nitrogen. This means you could actually contribute to reducing your carbon footprint while you’re working on your high-protein diet.

How roasted seaweed thins complement a vegan diet
Whether you’re an expert at plant-based recipes or you’re considering switching to a vegan diet for your health, dried seaweed thins tick all the boxes to give you variety, convenience and a whole new menu of potential protein-rich meals.
The salty, umami goodness is also low in calories, making it the ideal snack for anyone monitoring their intake or shopping for a gym-friendly taster. And the amino acids build up your protein to support muscle strength and development.
Simply crumble a sheet over your salad, blend into a fruit smoothie or create colourful, mouth-watering sushi wraps with a mix of crunchy veg topped with a spicy dipping sauce.
Crispy seaweed sheets: the top plant-based protein
Roasted seaweed thins are one of the most underrated sources of plant-based protein. But dried seaweed is actually (in our admittedly biased opinion 😎) the most impressively versatile and tasty protein out there.
The unmatched energy boost makes them a powerful alternative to traditional animal-based proteins, helping to support muscle development and overall health.
Unlike many proteins that require heavy processing, seaweed is naturally full of nutrients and comes straight from the most natural source – the ocean.
MORiSH seaweed thins offer convenient, clean protein and essential amino acids, providing a nutritious snack you can feel good about.
