Bursting with pure sea health
Seaweed is the only natural plant-based source of iodine which helps support:


Immunity & Wider Wellness
Why seaweed & natural nutrients help
Seaweed offers a wider range of nutrients, and particularly iodine which supports thyroid health that impacts so many aspects of your health and wellness.
In addition, Doctor Seaweed has added natural and plant based sources of vitamins B12 and D3 that specifically support immune health, and other aspects of wellness.
B12 is an essential vitamin, and which can be lacking particularly in a vegan diet, as the main sources are animal based. This essential vitamin contributes to the production of cells responsible for immune response.
The sources in our Immunity+ capsules are from mushrooms and provide an active form of B12 that is organic and plant-based, with 100% of your daily needs in each capsule.
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 our capsules 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.
Each capsule has 200% of your daily needs, which is the amount recommended by Public Health England.
Essential iodine for thyroid health
Having a sufficient natural source of iodine will support your normal:
- Energy yielding metabolism
- Thyroid health
- Cognitive function
- Maintenance of healthy skin
- Growth & development in children
- Functioning nervous system
Independent research from the medical school at the University of Glasgow has shown that our seaweed releases iodine more slowly, with longer retention in the body as compared to synthetic sources used in other iodine supplements.

Seaweed, of the right type and source, offers a huge amount of nutritional benefits, and a source of essential iodine and wider health and wellness benefits to help you feel wonderful.
With broader nutrition than land plants, seaweed contains a huge range of minerals, trace elements, vitamins, amino acids and essential fatty acids, and can be a great addition to a varied diet and healthy lifestyle.
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 essential 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.
Cultures around the world have all used seaweeds as a source of nutrients for the land, animals and our own food due to its incredible properties, availability and sustainability.
It is only recently that we are re-discovering the huge potential of this wonderful food for our health and wellness, which is delivered to you in the convenient and easy to use supplements from Doctor Seaweed’s Weed & Wonderful.
