The term seaweed refers to more than 10,000 species of marine algae and aqueous plants. Kelp is a specific type of brown seaweed much larger than other seaweed species.
Seaweeds are incredibly nutritious plants and sea kelp is a particularly rich source of iodine, an essential nutrient for thyroid health, and contains many health-promoting phytochemicals.
Let’s take a look at the differences between kelp vs seaweed and learn about kelp’s incredible health benefits.
What’s the difference between seaweed and kelp?
While kelp and seaweed are both highly nutritious marine plants that absorb the nutrients from their surrounding waters, they have some differences.
Seaweed is an umbrella term for a wide range of marine-based species of plants and algae, whereas kelp is a specific type of brown seaweed. This means that all kelp is seaweed, but not all seaweed is kelp.
The main differences between kelp and seaweed are their size and nutritional value.
Kelp is much larger and contains more iodine compared to other seaweeds. However, other types of seaweeds may have higher levels of other essential nutrients depending on their particular characteristics and growth location.
What is seaweed?
Seaweed refers to any aqueous plant or algae that grows in a saltwater marine environment. It grows in various shapes, sizes, and colors and can be found on rocky coastlines in the intertidal zone or deep ocean waters.
Its color has a direct effect on how much light seaweed absorbs and determines how close to the ocean's surface a specific species grows.
There are three broad seaweed categorizations based on their pigmentation:
Green algae
Brown algae
Red algae
Most seaweeds contain high amounts of vitamins and minerals and are popular sea vegetables consumed by many cultures worldwide.
What is sea kelp?
Kelp is a specific type of large brown seaweed that typically grows in cool and nutrient-rich waters.
It’s characterized by long, leaf-like blades and has flexible but sturdy stems. Giant kelp, a large seaweed species found predominantly in the Pacific Ocean, can grow up to 60 meters in length.
Kelp forests are an important habitat for marine life, and many coastal communities consume kelp as a staple ingredient in salads, soups, stews, and sushi rolls.
Health benefits of kelp and seaweed
Kelp and seaweed have been used for centuries as a source of nutrition and a natural remedy to lower inflammation, boost immunity, and support digestion.
Here are seven health benefits of kelp!
1. Nutritional powerhouse
Kelp ranks amongst the most nutritious seaweeds. It’s loaded with vitamins, minerals, and fatty acids.
“Compared to the terrestrial plants and animal-based foods, seaweed is rich in some health-promoting molecules and materials such as dietary fiber, omega-3 fatty acids, essential amino acids, and vitamins A, B, C, and E.” says Niranjan Rajapakse, biochemist and lead author of research published in Advances in Food and Nutrition Research investigating the health benefits of sea kelp.
2. Supports thyroid health
Kelp is an exceptionally concentrated source of iodine, an essential mineral for normal thyroid function.
Without adequate iodine, the thyroid gland can’t produce and convert thyroid hormones, resulting in underactive thyroid function, also called hypothyroidism.
This study published in Hormone Research in Paediatrics suggests that taking iodine-rich seaweed supplements improves thyroid function in people with hypothyroidism and goiter.
3. May help to lower inflammation
Seaweed species, including kelp, contain specific antioxidants such as laminarin and fucoxanthin that have potent anti-inflammatory properties.
Research published in Marine Drugs suggests that these seaweed-derived phytochemicals block the production of pro-inflammatory compounds and, at the same time, stimulate the release of anti-inflammatory molecules.
Kelp’s impressive anti-inflammatory effects may explain why kelp can benefit a wide range of chronic inflammatory conditions, including rheumatoid arthritis, psoriasis, and asthma.
4. Promotes healthy weight
Using kelp may help with weight loss. Iodine has been found to have potential fat-burning effects by promoting metabolic health.
Iodine deficiency can decrease your basal metabolic rate, which promotes fat storage and leads to weight gain and difficulty losing weight.
5. Supports reproductive health
Iodine in kelp supports thyroid health which is crucial for healthy hormone balance and reproductive health.
In addition, kelp contains several antioxidants that protect both egg and sperm cells from inflammation and cellular damage, which supports fertility and reproduction.
6. May lower cancer risk
There is evidence that regular seaweed consumption may lower the risk of cancer.
Although more research is needed to confirm kelp’s anti-cancer effects, several bioactive kelp compounds, including polysaccharides, fucoidans, and phlorotannins, protect cell structures and DNA from oxidative damage, which may lower the risk of cancer.
7. Natural diuretic
Kelp has mild diuretic effects and stimulates urine production, which helps flush excess fluids and toxins from the body.
Increased urine output also promotes healthy blood pressure and prevents water retention and bloating.
Who should use kelp
Kelp is a rich source of nutrients and dietary fiber, and most people benefit from regularly consuming kelp.
Because kelp boats incredible amounts of iodine, it's particularly beneficial for people with thyroid disorders and those at risk of low iodine intake and malabsorption.
A recent study published in Nutrients found that vegans and vegetarians are at increased risk of iodine deficiency.
In addition, industrialized farming has depleted iodine in a significant percentage of soils, and obtaining adequate amounts of this essential mineral from dietary sources alone is becoming increasingly more challenging.
Due to its wide range of health benefits, kelp use has been found beneficial for these conditions:
Hypothyroidism and goiter
High blood pressure
Heart disease
Inflammatory conditions
Weak immune defenses
Rheumatoid arthritis
Obesity
Eczema and psoriasis
Edema
Who shouldn’t use kelp
Kelp is generally safe and well-tolerated by most people.
However, due to its high iodine content, kelp can interfere with thyroid function, and people with hyperthyroidism and autoimmune thyroiditis shouldn’t use kelp products.
Kelp is rich in vitamin K, which impacts blood clotting. If you are taking blood thinning medication such as warfarin, it’s essential that you discuss the use of kelp with your healthcare provider to avoid excessive bleeding or other blood conditions.
How do you know if you’re low in iodine?
Iodine is essential for thyroid function, which regulates your metabolism, muscle function, hormone balance, digestion, and cognitive health.
Unsurprisingly, iodine deficiency can impact your whole body and manifest in a wide range of symptoms.
Here are common signs and symptoms of iodine deficiency:
Swelling in neck
Unexplained weight gain
Dry skin and brittle nails
Fatigue
Muscle weakness
Sluggish digestion
Constipation
Brain fog
While these symptoms may indicate low iodine levels, they can also be caused by other health problems, and it’s important to consult with a healthcare provider if you experience any of these symptoms to address potential medical issues and formulate an appropriate treatment plan.
Could sea kelp benefit you?
The human body can’t produce iodine and relies on dietary sources to obtain this essential nutrient. Unfortunately, mineral-depleted soils can make it hard to get all the iodine your body needs.
And, what’s more, environmental pollutants and toxins, including fluoride, chlorine, bromine, and even soy, can inhibit the absorption of iodine, leaving you at risk of deficiency.
Kelp and seaweed products have become increasingly popular in recent years—and for a good reason!
“Sea kelp is one of the world’s most concentrated sources of iodine, and taking a high-quality kelp supplement is an effective way to promote healthy iodine levels and support metabolic health,” says Dr. Berg.
Using sea kelp may help you to:
Support normal thyroid function
Feel rejuvenated and energized
Improve focus and mental clarity
Lose weight
Support digestive function
Enhance reproductive health
Combat inflammation
Lower the risk of cancer
Support healthy skin and nails
However, it’s important to understand that not all sea kelp supplements are the same. Like all seaweeds, kelp doesn’t just absorb nutrients from its surrounding waters. It also accumulates toxins!
Unfortunately, many low-quality kelp products are made from kelp grown in polluted waters.
Using these supplements can expose you to harmful heavy metals, which can cause gastrointestinal issues, inflammation, hormone imbalances, and immune reactions.
That’s why we searched wide and far to identify the highest-quality marine iodine sources available.
All ingredients in Dr. Berg Sea Kelp Enhanced Iodine are sourced from world-leading suppliers and harvested from pristine underwater forests.
