What is sea moss?
Sea moss, know scientifically as Chondrus crispus is a type of algae or seaweed, which is found on the Atlantic shores of North America, Europe, and the Caribbean Islands.
It’s known as a red alga, although it often comes in many colours, most popularly yellow or gold and purple – but you can also find rarer colours such as blue and green.
Its low number of calories and a fat means that sea moss is popular for its suggested range of health benefits, which may help to support a healthy lifestyle.2
It contains a small amount of protein, as well as offering a variety of vitamins and minerals. It’s also a great source of iodine and antioxidants.3
Throughout this article, you’ll find out everything you need to know about sea moss, including its benefits to your health and why it’s a popular addition to many supplements.

Often claimed to be a brand-new superfood, there are some possible health benefits to adding sea moss to your diet. Here are the top 10 potential benefits of sea moss:
-
Supporting digestive function
Seaweeds are a good source of live bacteria and fibre, which are known to support gut health.4
-
Supporting thyroid function
Sea moss contains iodine, which is good for your thyroid and potentially providing support for weight loss. However, if you are already taking medication to support your lack of iodine that its probably worth researching this further.5
-

-
Improved immune function
While there is no specific human study, one study into salmon suggested that sea moss can help build the body’s immune response.7

Sea moss has about two times more potassium than an average-sized banana. Potassium is a very important mineral that helps to support mental and emotional health.8
-
Heart health
Some studies suggest that sea moss can lower cholesterol and help thin the blood. However, this is not proven and requires more human research.9
-
Blood sugar management
One study into seaweed found the compound fucoxanthin, which is thought to normalise high blood sugar levels.10
-

Caribbean natives have been using sea moss as a natural aphrodisiac for many years. Its high zinc content is thought to increase sex hormones that play a key role in libido levels.11

There’s a lot we don’t know about eating seaweed and how it interacts with our bodies.
While it is generally thought that sea moss is safe for most of us, it’s still worth exercising a bit of caution. Choose reputable manufacturers and talk to your doctor if you have any worries.
It’s also a good idea to avoid overeating sea moss. It’s thought that this seaweed is a good source of iodine, but taking too much could influence how your thyroid operates.13
Use moderation when adding this superfood to your diet to be on the safe side.
How to include more sea moss in your diet

- Smoothies
- Shakes
- Soups
- Stews

Like with all supplements and superfoods, don’t expect a miracle cure from one ingredient. Try your best to keep to a healthy and balanced lifestyle, adding supplements depending on your unique nutritional needs.
Can you take sea moss every day?
Sea moss is a great source of various vitamins and minerals, as well as antioxidants that may benefit overall health.
However, its nutritional structure can fluctuate, and by consuming it in large amounts, you may ingest high levels of iodine or heavy metals, which can be harmful.14
Overall, scientists need to do more research on the health effects of sea moss in humans to determine its value in consumer health products.15
Still, from what we do know already, some of the benefits appear promising based on seaweed and sea algae studies.16
