Doctor Seaweed delivers his seaweed as a natural wholefood, rich in iodine, which 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 plant based source of iodine.

Inadequate iodine intake can lead to:
An underactive thyroid, with symptoms of:
- Tiredness and fatigue
- Weight gain or difficulty losing weight
- Sensitivity to the cold
- Depression
- Brittle hair and nails

Health Benefits of Iodine are:
Having a sufficient natural source of iodine will support your normal:

- Thyroid health
- Cognitive function
- Maintenance of healthy skin
- Growth & development in children

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.
