Although Chondrus Crispus is the most well-known sea moss type, it is not the only one. There are various forms of seaweed, each with its unique features and benefits. It would not be wrong to say that thousands of seaweed types grow in the ocean.

But, for now, we are sticking to the top five types of sea moss and their distinct characteristics. So, without further ado, let’s check out the details of different types of sea moss:

  • Irish Moss

    Scientifically known as Chondrus Crispus, Irish moss is the most popular sea moss and is used widely due to its health benefits. It is a species of red algae most commonly found along the Atlantic Ocean coasts. Irish moss contains over 18 essential minerals and nutrients, including iodine, iron, calcium, etc.

    For centuries, people have used Irish moss for its healing properties. Also, it is commonly used in cuisines as a thickening agent. It is because Irish moss contains carrageenan, a polysaccharide that provides thickening properties to when added to anything.

    Besides, Irish moss helps support the immune system, the digestive tract, and various body organs. It also promises multiple skin and hair benefits if applied regularly.


    • Red Gracilaria

      Scientifically known as Gracilaria chilensis, this sea moss type is found in the Pacific Ocean, especially around South America. Red Gracilaria also contains essential nutrients, including high fibre, protein, and minerals like calcium and magnesium.

      Red Gracilaria offers benefits similar to Irish moss and is excellent for overall health and wellness. The anti-inflammatory and antioxidant properties of Red Gracilaria make it a good health supplement.

      Furthermore, it offers skin and hair benefits like hydration, wrinkle prevention, scalp soothing, etc. It is consumed in various forms, like gel or capsules.


      • Cottonii Sea Moss

        Cottonii sea moss or Eucheum cottonii is another red algae growing in tropical regions like Southeast Asia. This sea moss is high in fibre, protein, and minerals like calcium and potassium.

        It is long, thin, translucent, and has reddish-brown fronds. 

        Again, Cottonii sea moss also offers various hair, skin, and health benefits. Moreover, it is an excellent source of carrageenan and is therefore used as a thickening agent in different foods.


        • Gigartina Sea Moss

          Gigartina sea moss is another red algae derivative that shares characteristics similar to Chondrus crispus.

          The main difference between both is Giartina grows in rocky areas in the North Atlantic, while Chondrus crispus is typically found in more sheltered areas. Also, both red algae variants contain carrageenan, but the quantity and nutritional value differ. 

          Gigartina sea moss is usually reddish-brown and can get as long as 20cm. Due to its high nutritional value and presence of carrageenan, Gigartina, like other red algae, is used in beauty products and food preparations and consumed in gel/capsule form. 


          • Eucheuma Seaweed

            Eucheuma Seaweed is scientifically known as Euchema spp. Eucheuma typically ranges in color from shades of green to red to brown, depending on its growing conditions and the species. 

            The main areas where this sea moss grows are shallow tropical waters. Additionally, its branches can go as long as 1 meter in length.

            Like most other types of red algae, Eucheuma also contains carrageenan and other essential nutrients, making it a healthy food option. The best thing about Eucheuma seaweed is it is easy to cultivate and can grow all year round. Additionally, it grows fast and requires no special fertilizers for growing conditions.  


            Differences Between Gold and Purple Sea Moss 

            The different types of sea moss have different colors. 

            The purple sea moss is Chondrus crispus since it is purple in colour. The sea moss may show reddish hues as well.

            The golden sea moss is, Genus gracilaria, which is gold in colour. However, it can vary in shades, with some being yellowish. 

            Now that you know the gold and purple sea moss, let’s explore their top differences. 

            • Growing Environment

            The main difference between gold and purple sea moss is their growing environment. Chondrus crispus mainly grows in shallow waters. On the other hand, Genus gracilaria can be found in both shallow and deep waters. 

            • Shade Ranges

            Although Irish moss is called purple sea moss, its shade can range from reddish brown to brown and purple, depending on where it's grown. Gold sea moss is usually gold, but its shade varies from light golden to yellow.

            • Nutritional Value

            Gold and purple sea moss have high nutritional value and many health benefits. But, due to slight differences, they have different nutritional values. Purple sea moss is a good source of iodine, iron, magnesium, calcium, and other vitamins.

            It also has a higher carrageenan content than gold sea moss. However, vitamin A, E, and K levels are found in higher amounts in purple moss as compared to golden one.

            • Taste

            The taste and texture of golden and purple sea moss vary slightly. Here’s what they are:

            • Gold sea moss has a more neutral texture with an earthy and salty taste.
            • Purple sea moss has a more dense and more robust taste. It tastes more like the ocean and is high in saltiness. But it’s more tender and delicate than gold sea moss.

            Advantages and Disadvantages of Sea moss 

            Although sea moss offers plenty of benefits, there might be a few side effects if it is over-consumed than the usage limit of 4 grams a day.

            Here are the advantages and disadvantages to keep in mind before incorporating sea moss into your routine.


            • Rich in Minerals

            Sea moss contains a long list of minerals and vitamins. This help to improve the functioning of the lungs and heart and improve immunity. According to a study, sea moss’s iodine content helps the thyroid function. 2

            •  Thickening properties

            Sea moss contains a thickening agent called carrageenan. This compound has thickening properties and is used in different sorts of foods like soups and stews to improve their texture and stability. 

            • Best for Skin Health

            Sea moss’s Omega-3 content helps protect your skin from harmful UV rays and delays the signs of aging. 3

            It also has anti-bacterial and anti-microbial properties, which help prevent acne, pimples, and other skin conditions. Besides, its antioxidant content and carrageenan compounds help keep skin problems at bay.

            • Helps the Digestive Tract

            Sea moss contains fibre which helps soothe the digestive tract and aid in bowel movements. Fibres are also amazing for constipation and may help alleviate symptoms of other digestive disorders.


            If you consume sea moss in a safe amount, it's less likely to harm you. However, sea moss is not suitable for everyone, so it's better to look at its side effects before starting to use it.

            Here are some of its prominent side effects.

            • Hyperthyroidism

            Sea moss contains a high quantity of iodine. Therefore, if you go over the prescribed dose, it can cause hyperthyroidism and other related issues. 4 The recommended sea moss dose is 4 grams per day.

            • Metal Poisoning

            Sea moss mainly grows in oceans and rocky waters. So, it absorbs some of the metal content in those waters, including mercury, arsenic, etc. 

            If you take more than the recommended quantity of sea moss gel, you can risk metal poisoning and other diseases due to the high levels of mercury. 5

            • Skin Allergies

            Lastly, sea moss is not for everyone. Although it offers extensive skin benefits, seaweed can cause worse allergies and reactions in some users. So, always do a patch test to see whether your skin reacts to the seaweed.

            Difference Between Pool Farmed and Ocean Farmed Seamoss

            Now that you know the major sea moss types, let’s have a look at sea moss grown in a pool vs. an ocean. 

            Sea moss that grows naturally differs from artificial pools and shallow waters. Due to its lack of nutrients, some people might consider pool-grown sea moss as 'fake sea moss.'

            But what exactly is different between both of them? Here’s a rundown.

            • Physical Appearance

            Both kinds of sea moss vary in colour and appearance. For example, pool-grown sea moss has a more uniform shape and usually is lighter in colour. It is because the sea moss is grown in a regulated environment with controlled exposure to sun, light, water, and temperature. 

            On the other hand, ocean-grown sea moss shows variations in physical appearance. That’s because of the varying degrees of temperature, sunlight exposure, waves, currents, etc. The result? The sea moss is sometimes darker, denser, or lighter and has no uniform appearance.

            • Nutrients Content

            The ocean-grown sea moss has a broader quantity of nutrient content, while the pool water only contains the nutrients added to the set-up. Hence, there’s a big difference between the nutritional value of sea moss grown in both situations.  

            According to a study, the nutrients found in ocean-grown sea moss are comparatively higher than those grown in artificial ponds. It is because the ocean contains a wide range of minerals, nutrients, and vitamins absorbed by the sea moss. 6 

            • Contamination Risk

            The contamination risk of pool-grown sea moss is higher because of the man-made surroundings. For example, the pools or artificial environment may contain dirt, bacteria, or harmful chemicals if improperly cleaned. 

            On the other hand, the ocean is a bit safer as it's the natural habitat of sea moss. However, polluted water and contaminated litter in the ocean can increase the risk of sea moss contamination. 

            • Sustainability

            Sustaining a man-made environment is pretty hard and requires a lot of effort. That’s because you need to mimic the ocean and consistently add clean water, nutrients, etc., into the water.

            Therefore, it’s harder, more time-consuming, and more expensive to sustain pool-grown sea moss. On the contrary, the ocean is an autonomous body that requires no extra effort to grow sea moss.  

            • Harvesting Time

            Sea moss grown in the ocean is usually ready in one year. However, pool-grown sea moss may take up to 2 years to fully grow and be ready for consumption. 

            The Takeaway

            Finally, we’ve reached the end of the article on sea moss types. 

            Please note that although there are wide sea moss varieties, they all have a high nutritional value and contain carrageenan content. And even though the Irish moss is the most well-known sea moss currently used, the other types also offer users the same (if not more) benefits and perks.
