Seagreens® Food Capsules

Enhance your daily nutritional intake with these easy to take vegan capsules.

Take two capsules per day to maintain and build the foundation of your health, or more to tackle specific health conditions or undertake a detoxification programme.

This unique blend of three sustainably-harvested shallow water seaweeds (Ascophyllum nodosum, Pelvetia canaliculata, and Fucus spiralis) has been specifically combined to provide an exceptionally broad nutritional profile.

Seagreens® Food Capsules contain all the micronutrients which we need even in tiny amounts, to feed the foundation of health on a permanent daily basis.

They provide a rich nutrient source of vitamins, minerals, essential fatty acids and trace elements in a natural, synergistic combination which your body recognises as food and can therefore absorb completely.

Seagreens® adds missing nutrients to your diet, helps you absorb more nutrients from other foods you eat and have a gentle detoxifying action helping you expel toxins, including heavy metals from the body.

Seagreens® Food Capsules can be taken by everybody, including during pregnancy.  They are suitable for babies, children and elderly people and do not interfere with any other medicines or supplements taken.

What's in it

Food Capsules contain a unique wholefood blend of finely milled Seagreens® native wild Wrack seaweeds Ascophyllum, Fucus and Pelvetia whose composition and health benefits Seagreens has studied and documented for over two decades. Vegetable capsules. Nothing added or extracted. Non-allergenic.

What it does

Widely used for comprehensive dietary completeness every day, and at higher levels in nutritional therapy. Contributes to healthy digestion, metabolism, circulation and cognition subject to research since 2008 with many published scientific papers.

How to use

2 capsules (1 gram) each morning, preferably with first food or drink, contributes a balance of micronutrients to a normal daily diet. In older age and to address health conditions and nutrition deficiencies, professional advice may be helpful before using higher daily amounts.

For children use half the amount, or Seagreens Iodine Lite+ are rcommended. Safe in permanent daily use for any age and health condition.


British Isles and Nordic region. The best seaweed species are found in different locations. Seagreens® has developed 5 food certified remote harvesting locations and production facilities in England, Iceland, Ireland, Norway and Scotland.

How do Seagreens® Compare with Nutritional Supplements?

Seagreens® Food Capsules and Seagreens® Food Granules have a more balanced and complete nutritional profile than fresh water algæ (spirulina, chlorella and blue-green algæ) and other seaweeds, whilst common kelp has too much iodine for long term daily use.

Where a conventional supplement might provide larger amounts of a particular vitamin or mineral to compensate for a known, specific deficiency, Seagreens® are a natural whole food which contributes directly to the broader and more complex nutritional balance on which our long term health depends.

Seagreens® nutrients and compounds are not found in conventional supplements because they cannot be replicated artificially, even in so-called 'food state' products. Seagreens are entirely compatible with supplements and medicines.

"Modern science confirms seaweed as one of Nature's all-round pharmaceutical miracles that can accomplish everything from warding off and treating several types of cancer, lowering blood cholesterol and blood pressure, thinning the blood, preventing ulcers, killing bacteria, even curing constipation"
J. Carter, The Food Pharmacy, Simon & Schuster, 1989.

Recommended Daily Intake

Normally 2 x 500mg capsules; less for children, more in pregnancy, physical training or recuperation. Take under professional guidance in detoxing, chronic health conditions and during treatment. Best taken early every day with food.

For balanced nutritional input in the general population, recommended daily intake is 2 Food Capsules each morning or split morning and midday or evening with food, on a permanent basis, except where the subject has regular physical exertion, is pregnant or breastfeeding, recuperating from illness, or where health or immunity is exceptionally compromised, or where specific treatment is being given, when up to 4 Food Capsules or 2 grams (half teaspoon) Food Granules may be deemed appropriate for relatively short periods (eg. the duration of pregnancy).

For heavy metals and radiation detoxification up to 6 Food Capsules or 3 grams (three quarter teaspoon) Food Granules daily (e.g. Preferably split over 2 or 3 meals) for at least 8 weeks, and thereafter 2 Food Capsules or 1 gram (quarter teaspoon) Food Granules daily for up to 24 months. The dosage in pre-and post-operative dental amalgam extraction was agreed with Dr J. Levenson of the British Society for Mercury-Free Dentistry.

Where the diet is varied, contains other good quality vegetables, and the general health of the subject is good, 2 Food Capsules or 1 gram (quarter teaspoon) Food Granules daily is an adequate maintenance intake especially with the occasional use in food of Seagreens® CulinaryIngredient. In all cases, experience shows that although debility may be addressed within weeks, genuine change and improvement accrues from long term use, and usually becomes very apparent to the subject from between 6 and 12 months. Prolonged daily use rather than higher intake is the key to efficacy.

Nutritional Profile/Ingredients - Seagreens® Food Capsules

Such a comprehensive balance of nutrients is found in no other natural food but seaweed.

From the primordial ocean to the vegetation and animals which remain our food today, our own bodily composition has its origins in the earliest organisms and the chemistry of life itself.

As life forms became increasingly diverse, they adapted to more specific diets. To survive on a narrower range of nutrients and protect themselves against toxicity, each evolved different mechanisms of selectivity and defence.

That is why we need a wide variety of land based foods, since each has a little of what we need. But nutrient loss in agricultural soils and manufactured and denatured food makes nutritional balance, especially of all the micronutrients, harder to achieve.

Almost as old as the ocean, seaweed is an outstanding whole food which complements and fills the gaps in all land food and special diets.

Food Capsules per gram (2 x 500mg capsules) provides:

Amino acids:

Alanine 0.85 mg, Arginine 0.44 mg, Asparagine 0.5 mg, Aspartic acid 1.73 mg, Cystine and Cysteine* 0.2 mg, Cystathionine 0.5 mg, Glutamic acid 1.72 mg,, Glutamine 0.5 mg, Glycine 0.78 mg, Histidine 0.25 mg, Homocysteine 0.5 mg, Hydroxyproline 0.5 mg, Isoleucine 0.57 mg, Leucine 0.97 mg, Lysine 0.71 mg, Methionine 0.2 mg, 1- Methylhistidine 0.5 mg, 3-Methylhistidine 0.5mg, Ornithine 0.5 mg, Phenylalanine 0.78 mg, Phosphoserene 0.66 mg, Proline 0.21 mg, Sarcosine 0.5 mg, Serine 0.71 mg, Taurine 0.5 mg, Threonine 0.8 mg, Tryptophan 0.17 mg, Tyrosine 0.6mg, Valine 0.74 mg. *Cysteine is a non-essential methionine amino acid derivative formed in collaboration with vitamins B6 and B12 whereas cystine, a compound formed when two amino acids form a disulfide bond, is a more stable semi-essential amino acid. Both are important in protein synthesis, detoxification and metabolism and cystine is a substrate for the cystine-glutamate cell transport by which it is readily broken down to cysteine in the cell.

Customer Reviews of Seagreens® Food Capsules

My doctor thought he was seeing another patient!

I've always bought the seaweed capsules and they have been a godsend. I have a slightly swollen thyroid goiter, which the NHS will not treat as the levels aren't low enough. These capsules, after taking them for just a week, made my hair and skin feel so much better and I had energy. My consultant at the time new I was taking these, as when I went back for a follow up, 6 months later, he thought he was seeing another patient. Thank you.

I have been taking sea greens for a few months now and this is the first winter in many years that I have managed to get through without suffering constant colds, coughs, and flu. I cannot believe how good they are and natural too. I give them to my husband as well. Wished I had discovered them years ago.

Sea greens food capsules

One word really WONDERFUL a great product I have always liked seaweed but it is not always available to buy fresh these great capsules make up for that so I can have seaweed everyday in a much more convenient way. I have been taking these capsule for quite a long time now and now approaching my 69th year , and I hope to be taking them still when I am 90 and beyond I feel they could be the Fountain of Youth. Everyone should try them and see the difference.

A hundred times better

I must say how good these capsules are as my wife and I feel a hundred times better at the age of 72, we have taken vitamins and minerals all our life but with these you can really feel the difference in your wellbeing.

From:  M. F. Johnson of Hornsea on 12/12/2011 11:28:58

The Holy Grail

I have been taking Seagreens Food Capsules and I cannot tell you how happy I am, they really do work.

They make me feel so content with myself, whereas before I had been taking vitamins and minerals for over 45 years and never felt the happy contented feeling I have with yours.

It as if I have finally, in my old age of 73, found the Holy Grail.

So could I thank you from the bottom of my heart for making a pill that really does work.

From:  M. F. Johnson of Yorkshire on 28/10/2011 11:35:00

Best possible supplements for my growing baby

In my first trimester of pregnancy I wanted to take the best possible supplements for my growing baby, a friend recommended me to Oceans of Goodness.

I had been feeling sick and tired pretty much the whole of the first 10 weeks, I have been taking the Seaweed for a couple of weeks now and am amazed at how different I feel, the sickness has greatly reduced, my skin looks better and I am less tired. I don't know if it is down the the seaweed but either way I am glad I swapped over to this natural alternative!

Pregnant & Happy from Sussex.

Seagreens have been very beneficial to my health

Seagreens have been very beneficial to my health. My dentist was very interested in the reduction of amalgum toxiity. Together with an alteration to my diet due to food intloerances and the use of Seagreens my gums are in excellent condition now. He is most impressed. My nutritional therapist has recommended that I continue taking Seagreens. I have recommended Seagreens to my friends and family.

From: Mrs P. O. of Newcastle Upon Tyne on 07/04/2008 09:41:10

Seagreens are fantastic...

Seagreens are fantastic as they give you just the right amount of nutrients that we lack in our daily meals. From feeling lazy and sleepy all day and suffering from insomnia for over 3 months, I recuperated over a very short period of time and was soon back to my slighty hyper active self. Combined with a healthy and balanced diet and exercise, 2 capsules a day will keep the doctor away.
