What are the health benefits of sea moss?
Sea moss has been used for centuries and there are many sea moss benefits.
Below is a table listing some of the potential health benefits of sea moss.
Improves gut health
Sea moss is a probiotic that helps improve gut health. It contains beneficial bacteria and also fiber, both of which help to promote gut health.
Promotes heart health
It is also high in magnesium, which can help to lower blood pressure and keep the heart healthy. There have also been studies that reveal it helps lower LDL, or the bad cholesterol in your body.
Helps with weight loss
Sea moss contains fiber which also helps you feel full among its other benefits. This means you can eat less and stay full longer than other foods lower in fiber.
Boosts immunity
Along with the other benefits, sea moss may also boost immune health. It does this by improving the immune modulation and immune response, but it has only been studied in fish to date.
Improves thyroid health
It does this due to it being a great source of iodine which is needed to help your thyroid function properly.
Helps fertility
This is purely anecdotal and has not been studied but some people have been using it to help with their fertility as a potential benefit. Peer-reviewed studies on humans need to be done before this can be stated as a fact.
Helps with blood sugar management
There have been two studies that show sea moss can help with blood sugar management.
The first study showed that fucoxanthin, a substance in sea moss, helped reduce blood sugars.
The other study was done on pigs and showed that a substance called alginate helped to prevent blood sugar spikes.
Although there have been studies, many more need to be done to verify all the benefits. Some of these benefits are anecdotal while others haven’t had enough studies done on humans or have only had animal studies.
Are there any adverse side effects to sea moss?
So far, there are no known adverse side effects to sea moss. Due to its high iodine content which, when consumed in large quantities, can cause hypothyroidism.
This can cause your thyroid to not function properly. Due to sea moss being submerged in ocean waters, you could also be exposing yourself to heavy metals but it would only be toxic in very large doses at high levels.
Lastly, the taste and texture may not be pleasant to some people’s personal preferences. When eaten raw, sea moss has a taste similar to raw clams or oysters which can be offputting for some people.
Its texture can also be similar to a sea moss gel which you may not like. As with any herb or supplement, it is always best to speak with a healthcare professional before starting to take sea moss if you are pregnant, breastfeeding, have a medical condition, or are taking medication.
How do you take sea moss?
There are many ways to take sea moss and it can be eaten raw or dried. When it isn’t raw, it is typically available as a capsule, powder, or gel form.
The most common is to either drink it in a juice or smoothie, add it to food, or take it as a supplement in pill form. You can also find sea moss in tea form but this is not as common.
If you are taking sea moss for the first time, start with a small dose and work your way up as you get used to the taste and texture.
Speak with a healthcare professional before taking sea moss if you are pregnant, breastfeeding, have a medical condition, or are taking medication.
