The Importance of Iodine, Vitamin B12 and Vitamin D


    Iodine is an essential nutrient you have to get in your diet.  The primary sources are white fish and dairy, with seaweed being the only natural and good plant based source of this essential nutrient. 

    Without sufficient iodine, your thyroid may not work as it should, as iodine is required in the production of thyroid hormones which have many impacts on your health and wellness.  A diet insufficient in iodine can result in numerous health conditions, including an underactive thyroid (hypothyroidism), with symptoms including weight gain/difficulty losing weight, tiredness, sensitivity to cold, depression, brittle hair and nails, dry skin and more (see the NHS website here for more info).

    One of the main benefits of a natural source of iodine like seaweed is the fact it can be released into the body more slowly, and has longer retention compared to artificial sources such as potassium iodide for example. This was demonstrated in an independent research trial which demonstrated that the artificial iodine was excreted more quickly than that from our seaweed. For more information about the study, check out this article.

    There are over 10,000 different types of seaweed, and we stick to just the one, knowing the iodine level of each batch and ensuring sustainable harvesting.  The seaweed is carefully produced into a powder using proprietary technologies, and every batch is tested to for other aspects of nutrition and safety, along with unique traceability and DNA Authentication so you know exactly what it is you are getting

    Vitamin B12:

    B12 is an essential vitamin, and which can be lacking particularly in a vegan diet, as the main sources are animal based.  Before it was discovered in the mid-20th century, scientists were unsure what was causing a wide range of health problems, and which turned out to be deficiencies in B12.  This essential vitamin does not often occur naturally in plants, and when it does the sources are said to be inactive.  However, the natural extracts used for Doctor Seaweed’s Weed & Wonderful Immunity+ supplements are from mushrooms and provide an active form of B12 that is organic and plant-based.

    Vitamin D3:

    Vitamin D is obtained from two sources: diet and from the action of sunlight on your skin.  An abundance of sunlight means you will get much of what is needed.  However, you do also need sources from your diet.  This is especially the case during winter months, if you are inside a lot of the time, have darker skin, and as you age due to a decline in your ability to produce vitamin D.  The organic and plant-based source used in Doctor Seaweed’s Weed & wonderful Immunity+ supplements is extracted from lichens, which are an amazing symbiotic relationship between fungi and algae or cyanobacteria.  The form extracted is vitamin D3, which is more commonly found from animal sources.  Research shows that D3 can be more effective than D2 (normally found in plants) at being absorbed by the body.

    Why Seaweed?

    A Forgotten Food

    Around 2.5 million years ago there was a transition from primitive to modern Homo sapiens. Research shows that at this time 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. Seaweed is a natural rich iodine source which is essential for brain development, and forms a crucial part of this story.

    Harvested in Pristine Scottish Sea Lochs

    Our Organic Hebridean Ascophyllum Seaweed is sustainably wild harvested around the remote islands of the Scottish Outer Hebrides. These pristine waters are carefully monitored and managed with exclusive harvesting rights from the Crown Estate. Our seaweed is carefully dried and milled using our Patent Pending technologies which ensures high quality, nutrient rich, and fully traceable products from sea to store.

    Doctor Seaweed (aka Dr Craig Rose)

    Doctor Seaweed (aka Dr Craig Rose) is a marine biologist who is passionate about bringing all the wonderful benefits of seaweed into your everyday life, and in ways that you’ll love. Craig’s vision is to see everyone able to enjoy and benefit from sustainable seaweed and to ensure it is not seen as being weird, but wonderful.

    Iron. As a blood donor years ago was looking for a natural source of iron to top up my levels & seaweed seemed the perfect answer. Now moved on to the ones with added natural vitamins as iv had a stroke & need help to repair cognitive skills , what better than seaweed.

    Great Product and Service

    I saw a positive difference in my energy after taking these capsules for a few weeks. I really like the natural ingredients and that the seaweed is sourced in Scotland. I like the product/ethos so much that I’ve now taken out a subscription.

    Seaweed lover

    I definitely feel more energised and mussels and joints seem not so creaky. Will continue to use the tablets. All thanks to Lucy

    Seems a good idea to me. A bit soon to judge benefits but will continue taking caps. I had a jelly desert made from carrageen seaweed as a child!

    Both oil and capsules are presents for 2 different Vegan friends so I can't comment further.
