Other emerging small studies have explored the potential benefits of sea moss for heart health, mood, immune health and more. However, the research had not yet found anything conclusive, and studies have mostly been done on animals, in the lab or in extremely small sample sizes, so whether sea moss has these benefits is unclear and more robust research in humans is needed.

It’s also worth remembering that there isn’t a lot of research around the benefits of sea moss, and it can’t provide all the nutrients you need. Stick to a healthy and balanced diet first and foremost and consider adding sea moss to your diet if you want to once you’ve checked with your doctor.

Possible sea moss side effects

There’s a lot we don’t know about eating sea moss and how it interacts with our bodies. While it’s 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 important to avoid overeating sea moss. Sea moss is a source of iodine and other heavy metals, and while not bad for you in small amounts, taking too much could lead to iodine poisoning and leave you feeling unwell.¹⁰

Stick to the acceptable serving size and use in moderation when adding this alga to your diet – just to be on the safe side.

How to include sea moss in your diet 

Sea moss comes in many forms, from powder to whole, which means you have lots of ways to take it – and one of the most popular forms is sea moss gel. Sea moss gel is derived from sea moss and is sometimes used as a thickening or stabilising agent in food, medicine, and cosmetics. It benefits from all the same properties as sea moss, as it also contains minerals like iodine and potassium.¹¹

Sea moss gel has a mild flavour, which makes it a versatile ingredient in your cupboard. You could try adding sea moss to smoothies, shakes, soups, stews, jams, spreads, cakes, baked goods or even ice cream.

As with all supplements and foods, don’t expect a miracle 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 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.¹²

The British Dietetic Association recommends seaweed is not eaten more than once a week, as too much can cause digestive upset or even hyperthyroidism due to the high iodine content. ¹⁰¹

Overall, scientists need to do more research on the health effects of sea moss on humans to determine its value in consumer health products. Still, from what we do know already, some of the benefits appear promising based on emerging research in seaweed and sea algae studies.⁹

The final say 

Sea moss is a source of a variety of vitamins and minerals, as well as antioxidants that may benefit overall health. 

However, it has varying nutritional properties and when using it in significant amounts, you may consume high levels of iodine or heavy metals. Generally, more research is needed into the claimed health benefits of sea moss in humans, but early studies are promising in similar types of seaweed and algae.
