Bladderwrack is an edible brown seaweed (Fucus vesiculosus) that is extremely rich in health-promoting nutrients. It contains vitamin A, and vitamin C, plus macro minerals and trace minerals. 

Bladderwrack contains a large dose of iodine and was the plant from which iodine was originally discovered. Iodine is a major component of thyroid hormone, the hormone responsible for setting the body's metabolic rate. 

Natural health practitioners recommend kelp for a variety of conditions including hypothyroidism, hair loss, ulcers, constipation, poor mineral status, and some female hormone imbalances.

Iodine Content In Bladderwrack

Due to the depletion of iodine in the soil, it has become extremely difficult to get sufficient amounts from diet alone. To counter this problem, staple foods like table salt are enriched with iodine to help cover the gap. In the case of iodized salt, the inorganic form of iodine is added. Natural, organic sources, such as those derived from bladderwrack are much more absorbable and easier for the thyroid gland to use than the inorganic (mined) sources found in enriched foods.

Top Health Benefits of Bladderwrack

In addition to the vitamins and iodine, bladderwrack also contains mucilage (soothing soluble fibre), and many essential minerals. Bladderwrack's mineral content supports the brain, nerves, blood vessels, hair, skin and nails. It also contains zeaxanthin, which can help to protect the eye from oxidative and light-induced damage.

Iodine Content and Radioactive Iodine

Because of the rich iodine content, bladderwrack has the potential to protect the thyroid from taking up radioactive iodine in the case of a nuclear disaster, as seen in Japan in March 2011. Radioactive iodine is strongly associated with the development of thyroid cancer, especially in infant and child populations. The iodine found in bladderwrack binds with receptors on the thyroid gland, essentially filling the receptors, making it impossible for radioactive iodine to bind and be utilized by the gland in the making of thyroid hormone. This can provide short-term protection against a sudden threat. Excess iodine can cause thyroid dysfunction; therefore, it is not advised long-term, especially in children. Individuals with a hyperthyroid condition are not advised to take bladderwrack or iodine.

Hypothyroidism

Some cases of hypothyroidism can be attributed to a lack of iodine and this causes a swollen thyroid (goitre). When there is insufficient iodine available to the thyroid gland, it is not able to produce sufficient thyroid hormone. Thus, it cannot properly regulate the body's metabolism, a condition known as hypothyroidism. Hypothyroid individuals experience many symptoms due to a lack of thyroid hormone including fatigue, weight gain, hair loss, constipation, and frequent colds and flu.

Menstrual Cycle Regulation

Many women have difficulty with irregular cycles and menstrual-associated diseases. One 2004 study found that taking 700-1400mg/day of bladderwrack helped to increase the menstrual cycle length and decrease the days of menstruation per cycle. Thus bladderwrack can help to regulate the female menstrual cycle.

Heartburn

The soluble fibre found in bladderwrack can help to coat the digestive tract and protect it against damage by refluxed stomach acid. Because of this, bladderwrack is often found in supplements for the treatment of heartburn (acid reflux).

Where Can I Find Bladderwrack?

Bladderwrack can be eaten raw but it is usually found dried, or powdered for use as a salt substitute. Supplemental bladderwrack can be found in tablet form, and also as a tea. 

In supplement form, iodine is usually derived from natural seaweed sources and is available in both liquid and capsule or tablet, forms. The standardized types of these supplements contain a higher level of iodine and a consistent amount in each tablet – usually about 150mcg (0.15mg). This is the preferred form for clinical use in low thyroid conditions, while the unstandardized bladderwrack is suitable for people in need of a daily supplement for health maintenance. 

Women seeking to balance their menstrual cycle can supplement bladderwrack at between 700 and 1400mg daily.

Irish Sea Moss was once only heard of in coastal Ireland, but in recent years, it has made quite a mark in the global natural health industry.

Irish Sea Moss is a red algae that’s also known as Chondrus Crispus. It’s been used for centuries in ancient medicine due to its ability to soothe the respiratory system, support digestion, and boost immunity. Today, Chondrus crispus is gaining popularity as a plant-based superfood rich in over 90 essential minerals, including iodine, magnesium, and potassium. With a nutrient profile that impressive, it’s no wonder Irish Sea Moss is so popular. Let’s explore more about this ancient algae and the key health advantages it has to offer.

What Is Irish Sea Moss?

As mentioned, Irish sea moss is a species of red algae that grows along the rocky Atlantic coasts of Europe and North America, with an affinity for the Irish coastline. It’s often confused with other sea moss varieties like Gracilaria, but what’s distinctive about Chondrus Crispus is its fan-like appearance and dark purple to reddish hues.

Even more so, Irish sea moss contains 92 of the 102 minerals your body needs, including:

• Iodine – a critical nutrient for thyroid function
• Iron – an essential mineral for oxygen transport in blood
• Magnesium – supports nerve and muscle function
• Potassium – responsible for regulating fluid balance and blood pressure
• Zinc – a mineral for immune and skin health

It is also rich in polysaccharides, especially carrageenan, which gives sea moss its signature gel-like texture. These compounds are believed to have antiviral, antimicrobial, and anti-inflammatory properties, making Irish Sea Moss a powerful addition to wellness products.

Top 4 Health Benefits of Irish Sea Moss

This algae is praised for its multi-purpose support from gut health to skin rejuvenation. Here are 4 major health benefits backed by traditional medicine and modern science.

1. Immune System Support

Considering its rich vitamin, antioxidant, and mineral composition, it’s no surprise that Irish Sea Moss is a natural immune booster. It contains immune-boosting nutrients like zinc, selenium, and vitamin C, which strengthen immune defence and protect against pathogens.

Sea moss also contains antiviral and antimicrobial properties, which may help the body fend off infections, reduce inflammation, and promote healing. Beyond that, it possesses the mucilaginous texture of sea moss, which is known to soothe irritated tissues in the lungs and throat, making it a traditional remedy for coughs, sore throats, and respiratory infections.

2. Gut & Digestive Health

Irish sea moss acts as a prebiotic, which helps feed the good bacteria in your gut, helping support a healthy microbiome.Its mucilage content, a type of soluble fibre, helps soothe the digestive tract, regulate bowel movements, and promote gut lining integrity. This makes it beneficial for gut health issues like constipation, leaky gut, and irritable bowel disease.

It can also help detoxify the digestive tract due to the carrageenans found in it. These carrageenans help bind to and remove toxins, further enhancing your gut health.

3. Skin Health & Beauty Benefits

Irish sea moss is quickly becoming a favourite in natural skincare, both as a topical treatment and a supplement. Its high sulfur content provides antimicrobial and anti-inflammatory properties, which can help combat acne, calm redness, and improve overall skin clarity.

When taken internally, the minerals it possesses, like zinc and vitamin A, help support collagen production and skin cell turnover. This can help smooth skin texture, improve skin hydration, and enhance your skin's natural glow.

Much like aloe vera, topical applications of Irish sea moss gel are beneficial to soothe eczema, psoriasis and dry patches thanks to its cooling, moisturizing qualities.

4. Thyroid Function & Hormonal Balance

Sea moss is one of the richest plant sources of iodine, a mineral essential for healthy thyroid function. The thyroid gland regulates hormones that control metabolism, energy levels, temperature, and mood.

An iodine deficiency can lead to conditions like hypothyroidism, causing symptoms such as fatigue, weight gain, and brain fog. By providing natural, bioavailable iodine, Irish sea moss helps support optimal thyroid hormone production and hormonal balance.

Because of its impact on hormones, sea moss is also popular among those managing PMS, fertility issues, or adrenal fatigue.

How To Use Irish Sea Moss Supplements

There are several ways to incorporate Irish Sea Moss into your daily routine, given the many formats it’s available in. You can purchase it in gel, powder, capsule, and dried formats, giving you the flexibility based on your personal preference.Here’s how you can use each format:

• Gel – this is the most popular and traditional form. It’s made by soaking and blending raw dried sea moss, and it can be used by adding to smoothies, teas, soups, or consumed by the spoonful. It has a mild taste and can last up to 3 weeks in the fridge.

Dosing: 1-2 tablespoons daily

Pro Tip: mix with lemon, ginger, or cinnamon for added flavour and health benefits.

Capsules – if you prefer the convenience or don’t like the texture of gel, capsules are also available. Irish sea moss capsules are often blended with bladderwrack or burdock root, two herbs that work synergistically with sea moss for detoxification and thyroid support.

Dosing: typical doses range from 500-1000mg/day, but it’s best to follow brand recommendations on the label or those given by your healthcare provider.

• Powder – powdered formats can be mixed into baked goods, energy bites, or shakes. It’s shelf-stable and a great choice for travel or DIY skincare masks.

• Raw Dried Sea Moss – for purists who want full control, dried formats can be soaked, rinsed and blended into gel for an at-home DIY. Make sure to purchase wildcrafted, sustainably harvested varieties to avoid contaminants.

1. Excess Iodine Intake: Too much iodine may overstimulate the thyroid, potentially causing hyperthyroidism or thyroid inflammation. Sticking to the recommended doses can help avoid this issue.

2. Heavy Metal Contamination: Sea moss grows in the ocean and can absorb heavy metals like mercury or lead. Always purchase these products from reputable brands that offer third-party testing for purity and safety.

3. Digestive Upset: Because of its mucilage content, consuming too much sea moss may cause loose stools, bloating, or gas, especially when first introduced.

4. Allergic Reactions: Though rare, people with sensitivities to seaweed or shellfish should avoid these products.

Pregnant or breastfeeding women, or those with thyroid disorders, should consult a physician before taking these supplements.

What is The Thyroid?

Nestled in the front of your neck, the thyroid is a small, butterfly-shaped gland that plays a crucial role in regulating your body's metabolism. It controls how your body processes sugar, fat, and protein. It also influences key functions, like heart rate, body temperature, digestion, fertility, and skin and bone health. Maintaining the right balance of thyroid hormone is vital, ensuring your body stays energized while also having time to repair and thrive.

Symptoms of Hypothyroidism

Low thyroid function is common in today’s society. This is due in part to stressful lifestyles, lack of nutritious foods and an increase in environmental pollutants. 

Signs your thyroid may be low functioning include: 

• Weight gain
• Frequent infections
• Dry and cold skin
• Poor nail growth and hair loss
• High cholesterol
• Swelling of the hands and feet
• Menstrual irregularities
• Goiter
• Fatigue and an increased need for sleep
• Decreased initiative, lack of concentration, and poor memory
• Bowel changes
• Muscle and joint aches
• Allergies and asthma

Supplements to Improve Thyroid Hormones

If you notice a change in your thyroid hormone levels and are diagnosed with hypothyroidism, Thyroxin is available by prescription in Canada. But, if you'd like a natural product, a supplement called Thyroid or Armour thyroid contains both T4 and the more active T3. This is important for a small percentage of people who can’t convert T4 into T3. 

Most thyroid glandular supplements are certified thyroxin- free to eliminate the risk of sending users into a hyperthyroid state. The best source for glandular extracts is New Zealand, where they are free from pesticides, growth hormones, antibiotics and disease.

Here are several alternatives to enhance your body’s production of thyroxin without taking thyroxin itself:

• Protein intake is important because it contains the amino acid tyrosine, a precursor to thyroxin.
• Vitamins and minerals are needed to produce and convert thyroxin into the more potent T3. These nutrients include iodine, copper, zinc, selenium, vitamin A and vitamin E.
• Thyroid glandular is an extract of the thyroid gland of an animal, usually a sheep or cow. It supports the activity of the thyroid and regulates metabolism. It may provide its users with a mild increase in energy and stamina.

Dietary considerations for optimizing thyroid functioning include:

• Avoiding chlorinated and fluoridated water because they block iodine receptors in the thyroid. 
• Avoiding broccoli, brussel sprouts, cabbage, cauliflower, kale, peaches, pears, rutabagas, soybeans, onions, spinach and turnips because they suppress thyroid hormone function.
