It’s the best-kept secret in the health and beauty industry: seaweed is a saviour.

We’re talking expert levels of superfood sway. From boosting our energy to improving our immunity, giving our skin a natural glow and speeding up our metabolism to saving us from menopause symptoms, seaweed is a proven health hero.

And in this age of synthetics, isn’t it refreshing to know that an all-natural remedy is out there for so many of our wellness goals?



Because seaweed naturally supports our bodies’ production of thyroid hormones – which, basically, help almost every important function going on inside of us.

Around 2.5 million years ago, there was a transition from primitive to modern Homo sapiens. Research shows that our ancestors moved to coastal environments and started eating seaweed. The nutrients that were (and still are) in seaweed allowed for the evolution of the human brain.

So, in a nutshell, we owe the intelligence of our whole species to this little clump of algae.


Seaweed is a naturally rich source of iodine, which is essential for brain development.

Our bodies need iodine to make thyroid hormones which (as part of the endocrine system), control our metabolism. This, in turn, regulates our heart, muscle and digestive function, as well as our bone maintenance. We also need thyroid hormones for the brain development of babies during pregnancy and infancy.

The problem? Statistically, we’re not getting enough iodine in our diets.

Research shows the UK is one of just two high-income countries with iodine deficiency issues and has a worse rate than some developing countries. This is largely linked to poor intake of iodine-rich foods, such as white fish, dairy and the right kinds of seaweed.

Whitley Bay local Dr Craig Rose is a marine biologist and seaweed enthusiast.

After working with seaweed for years on various commercial and research projects – from biofuels to food and nutrition – Craig identified the urgent need for seaweed in our diets and began the clinical trials and development process that led to Doctor Seaweed’s first Weed & Wonderful supplement in 2015.

‘Seaweed is the most incredible natural resource’ Craig tells us. ‘It can meet all the needs we have across food, energy, health and wellbeing. My vision is to see people discover how seaweed can and will benefit their lives and offer a hopeful and sustainable future.’

As well as knowing his stuff – Craig has a degree, masters, and a PhD in Marine Science – Doctor Seaweed also lives and breathes aquatics. You can usually find Craig on his boat, scuba diving whenever he gets the chance.

He’s also a regular volunteer at Tynemouth Aquarium, often diving into shark and seal tanks to clean them. So, next time you visit, make sure to say hello!


The key to Doctor Seaweed’s whole ethos is natural goodness.

See, independent research shows that naturally sourced seaweed releases iodine slower and with longer retention in the body than artificial sources, (such as potassium iodide), which are often used in other supplements.

But while all seaweed is good, some types are just… better.

Why? Well, because the nutritional properties of seaweed change depending on its type, where it’s harvested from and how it’s processed.

The Organic Hebridean Ascophyllum seaweed that is core to Doctor Seaweed’s Weed & Wonderful range is wild harvested sustainably from the pristine waters of the Scottish Outer Hebrides. These waters are monitored by the Crown Estate to ensure they are of the highest quality. The seaweed itself is harvested to promote regrowth, meaning only the top layers are trimmed.

Nothing is added. Nothing is taken away. So, you can be sure of the highest natural quality of British supplements from sea to store.



Iodine regulates our metabolism: the process of converting the food we eat into energy to help cells function and grow.

If we’re not getting enough iodine in our diets, as studies suggest, our normal metabolic functions – like the regulation of our heart rate, body temperature and weight – can be disrupted, leaving us feeling tired and run down.

Doctor Seaweed recommends: Pure Organic Seaweed  

One tablet (500g) gives you the same amount of iodine as you’d get from 1 litre of cow’s milk, three portions of mackerel, almost two whole blocks of cheese or 9kg of fruit and vegetables – all for just 37p a day.



Besides being inherently antiseptic, iodine – and, therefore, the thyroid hormones it helps to produce – provides constant surveillance against abnormal cell development.

By supporting B-cell (or antibody) development, iodine protects against unusual bacterial growth in the stomach and can coat and neutralise both biological and chemical toxins. Iodine also seems to increase immune cell function – meaning our bodies’ natural defences are fortified.

Doctor Seaweed recommends: Immunity+

As well as pure Scottish seaweed, these supplements contain plant-based sources of vitamins D3 and B12, both of which specifically support immune health naturally. Every capsule contains your daily requirements for all three core ingredients.



Hormonal imbalance, hot flushes, memory loss, digestive issues, fatigue, hair loss, weight gain, disrupted sleep, loss of libido… the symptoms of menopause are varied and plentiful.

But they also overlap with symptoms of thyroid conditions.

Data suggest the decrease of oestrogen during menopause affects how our thyroid receptors allow hormones to enter cells, affecting both our cellular and thyroid function.

So, by bolstering our thyroid hormones with iodine, we can also limit the severity of our menopausal symptoms.

Doctor Seaweed recommends: Menopause+    

Alongside essential iodine, Doctor Seaweed’s Menopause+ supplements contain plant-based vitamins C, D3, B-complex and Red Clover, all of which naturally support various symptoms associated with all stages of the menopause.


Nails, Hair & Skincare

A lack of iodine in our diets can really do a number on our beauty regime.

Thyroid hormones help control the growth of hair follicles, so when their levels are low our hair may stop regenerating; brittle or splitting nails are other common symptoms of iodine deficiency; and thyroid hormones also help skin cells regenerate, leading to 77% of people with low thyroid hormones – as a result of iodine deficiency – experiencing dry, flaky skin.

Doctor Seaweed recommends: Beauty+  

A natural glow starts with the right nutrition. As well as essential iodine, these Beauty+ supplements contain plant-based sources of vitamins A, B2, B3, C, E biotin, selenium, and zinc – all of which naturally support hair, skin and nail growth.


Focus, eyesight & cognitive function

Iodine deficiency is the leading cause of intellectual disability around the world and is the greatest single cause of preventable brain damage.

It’s a crucial nutrient throughout life, but especially during pregnancy and infancy, where thyroid hormones regulate growth in a child’s developing brain.

Not that the cognitive benefits of iodine can only be seen in children; a study of more than 1,000 adults found that those with higher thyroid hormone levels performed better on learning and memory tests.

Iodine has also been known to improve eyesight, especially in cases of age-related deterioration and colour perception.

Doctor Seaweed recommends: Focus+    

Each of the key nutrients in Doctor Seaweed’s Focus+ supplement – among which are, alongside iodine, vitamins B1, B5, B6 and B12, omega 3, zinc and biotin – are essential in supporting brain health, focus, energy and vision.



The natural iodine within the seaweed is placed into capsules for ease of taking and is absorbed much in the same way as it would be from eating other whole food sources, such as white fish or dairy. To put the iodine content into context, one 500mg Pure Seaweed Capsule contains the same iodine levels as a portion of haddock, which is within safe limits.

Although all products in the range are natural and contain no synthetic ingredients, it is still important to consider your wider diet, supplement regime and existing iodine intake when introducing any new supplements into your diet. It’s always wise to consult your GP first if you have any questions or concerns.
