Sea Moss for PCOS: Natural Solution or Just a Fad?

If you’ve seen “sea moss for PCOS” trending on social media, you might be wondering whether it actually works or if it’s just another wellness fad.

As a registered dietitian who also has PCOS, I’m always interested in these new types of trends. In this blog post, I’m going to break down what sea moss really offers for PCOS, the potential drawbacks, and whether it’s worth adding to your routine.

What is Sea Moss? 

Sea moss is a type of seaweed or red algae that is found in oceans around the world. It’s traditionally used for its mineral content and as a natural thickener in foods. It contains small amounts of essential nutrients such as iodine, potassium, magnesium, and antioxidants. 

There are many different types of seaweed species but Chondrus crispus, or Irish sea moss, are the most commonly sold varieties. Sea moss is usually sold in different forms such as gels, powders, capsules, or drinks. 

Benefits of Sea Moss for PCOS

Like many things, there’s currently no research on sea moss specifically for PCOS. Some of the nutrients in sea moss may support common PCOS symptoms or concerns. Let’s dive into some of these potential benefits.

May Support Thyroid Health

Sea moss naturally contains iodine, a mineral needed for thyroid hormone production. Since thyroid disorders, such as Hashimoto’s hypothyroidism, occur at a higher rate in those with PCOS, getting enough iodine is important. Here’s the catch though: too much iodine can actually harm thyroid function. Iodine supplements should be used cautiously by those with PCOS, and especially those with thyroid disease.

Provides Antioxidants

Antioxidants help combat inflammation and oxidative stress, both of which are concerns for most people with PCOS. While sea moss does contain antioxidants, it isn’t uniquely potent compared to fruits, vegetables, herbs, or spices.

May Support Gut Health + Blood Sugar Levels

Sea moss contains fiber, which has numerous health benefits. Fiber can support digestion, gut health, and balanced blood sugar levels. A healthier gut can improve insulin sensitivity, inflammation, and androgen levels. It also plays an important role in your metabolism and may aid in weight loss. While this may sound great, the amount of fiber you get from sea moss is negligible compared to whole food sources such as fruits, vegetables, whole grains and legumes.

Mineral Support

The minerals in sea moss, such as magnesium, iron, and zinc, play roles in regulating insulin levels, testosterone levels, ovulation and menstrual regularity. Similar to the fiber content though, the amount of these minerals in a typical serving of sea moss is negligible. While it may be beneficial, you can easily obtain these nutrients from whole foods or a general multivitamin instead.

Downsides of Sea Moss for PCOS

Before spending your money and adding sea moss to your routine, it’s important to understand its limitations and risks.

Inconsistent Iodine Levels

The iodine content of sea moss can vary depending on where it’s harvested from. Too much iodine may cause thyroid dysfunction, which may actually worsen symptoms of PCOS like fatigue, weight gain, or irregular cycles.

I’ve reached out to one company in the past regarding the iodine content in their sea moss. This was their response: “Sea moss is renowned for its high iodine content, which is essential for thyroid function. However, the exact amount of iodine in a serving of sea moss gel can vary due to factors like the sea moss’s source and preparation methods. Therefore, it’s challenging to provide a precise iodine measurement per serving.”

I’d imagine this kind of answer is true across the board for companies that sell sea moss.  

Heavy Metal Contamination

Sea moss may naturally absorb heavy metals from the water it grows in. Without third-party testing, it’s hard to know if a product is truly safe.

Not a Proven PCOS Treatment

Despite online claims, there currently isn’t any research showing sea moss improves menstrual regularity, fertility, insulin resistance, androgen levels, or other PCOS symptoms..

Digestive Upset

The most common side effect of taking sea moss is digestive issues such as nausea, bloating, abdominal pain or diarrhea. 

Should You Try Taking Sea Moss for PCOS?

Whether or not sea moss is a good choice for you will come down to you as an individual. Sea moss isn’t harmful for most people when taken in small, sensible amounts. It may even add some minerals or fiber to your diet, albeit, a relatively small amount (aside from iodine). 

But it’s not a magic fix for PCOS, and it shouldn’t replace evidence-based strategies like balanced meals and lifestyle changes such as regular exercise, quality sleep, and dietary supplements with actual scientific evidence behind them (like inositol).

If you have a history of thyroid disease, it’s probably a good idea to avoid sea moss entirely since the iodine content can be so inconsistent. 

What’s The Best Sea Moss for PCOS?

After speaking with your healthcare provider, if you do choose to try sea moss, look for products from reputable companies that undergo third-party testing.

For sea moss gels, this one and this one are typically good options. 

For sea moss capsules, I like this one.

While I don’t love gummy supplements, this is one of the better sea moss gummies supplements. Gummies tend to have more added sugar, so that’s something to be aware of.

The Bottom Line

Sea moss can offer some general health benefits, but it’s not a proven supplement for PCOS. It can provide a variety of minerals, antioxidants, and fiber in small amounts (aside from iodine). While iodine is necessary for thyroid health, too much iodine can actually harm thyroid health. 

If you enjoy sea moss and tolerate it well, it could potentially fit into a balanced routine. Sea moss isn’t necessary though and many of its benefits can be provided by just eating more whole foods.
