Soil Association certified organic seaweed, with the iodine content actually stated — which is rarer in this category than it should be.
What the iodine does
- Iodine contributes to the normal production of thyroid hormones and to normal thyroid function.
- Iodine contributes to normal cognitive function and to the normal functioning of the nervous system.
- Iodine contributes to normal energy-yielding metabolism and to the maintenance of normal skin.
192µg of iodine per capsule — 128% NRV. Note that this is per capsule, not per day. Please read the dosing note below.
⚠️ Iodine — worth doing the arithmetic
Our label allows 1 to 3 capsules a day. At one capsule that's 192µg. At three it's 576µg, which is above the 500µg daily figure UK guidance sets for iodine from supplements. We'd suggest one capsule a day unless a healthcare professional has told you otherwise, and bearing in mind that seaweed, dairy and fish all contribute iodine from your diet too.
What's in the capsule
300mg of organic seaweed — Ascophyllum nodosum and Fucus vesiculosus — with 290mg of organic spirulina, artichoke, chlorella, green tea, alfalfa and cayenne pepper. Those six are supplied as a proprietary blend, so the individual weights aren't declared; we'd rather say so than let you assume otherwise.
Certified organic
Soil Association certified organic (GB-ORG-05) — which matters for seaweed, since it takes up what's in the water around it.
Allergen advice: contains naturally occurring sulphites from the spirulina and chlorella.
Suitable for vegans. Halal and Kosher certified. Made in the United Kingdom to GMP standards. 100 capsules, covered by our 60-day money-back guarantee.

- Other ingredients — 290mg: organic spirulina, organic artichoke, organic chlorella, organic green tea, organic alfalfa and organic cayenne pepper
Those six are supplied as a proprietary blend, so the individual weights aren't declared on the label. We'd rather tell you that plainly than let you assume otherwise. NRV = Nutrient Reference Value.

How to take it
⚠️ Read the iodine note first
One capsule provides 192µg of iodine — 128% of the daily Nutrient Reference Value. Our label permits 1 to 3 capsules a day, which at three capsules comes to 576µg. UK guidance sets 500µg a day as the figure to stay below for iodine from supplements, so three capsules puts you above it.
We'd suggest one capsule a day unless a healthcare professional has advised otherwise.
Also worth knowing
- Iodine is one of the few nutrients where more is genuinely not better. Too much can affect thyroid function just as too little can.
- Dairy, fish, eggs and seaweed all supply iodine from your diet, and several other supplements contain seaweed or kelp. Those add up.
- If you have a thyroid condition, take thyroid medication, or are pregnant or breastfeeding, speak to your GP before taking this product.
- Not suitable for children — a single capsule exceeds the daily upper intake recommended for young children.
- Contains naturally occurring sulphites.
Take with water. Do not exceed the recommended daily intake. Food supplements should not be used as a substitute for a varied diet and healthy lifestyle.

Your Wellness Journey
From where you are now, to where you want to be — with consistent support.
Where you are now
You're looking at a seaweed supplement and want to know exactly how much iodine is in it — a question a surprising number of labels don't answer.
Start with one a day
One capsule provides 192µg of iodine, 128% NRV — already more than a day's reference intake. Read the dosing note before taking more.
Count your other sources
Dairy, fish and seaweed all supply iodine, and so do some other supplements. It's one of the few nutrients where more is genuinely not better.
Stay stocked
100 capsules — over three months at one a day. Reorder before you run out.
Before you Buy
The questions we hear most — answered straight.
Is this product Soil Association Certified?
Yes. All the botanical ingredients in this complex are certified organic by the Soil Association, guaranteeing they are grown without synthetic pesticides, heavy metals, or artificial fertilisers.
What are Seagreens®?
Seagreens® are a premium, sustainable source of wild-harvested seaweed. They provide a pure, food-form source of iodine and trace minerals that are often low in modern UK diets — particularly for people who eat little fish or dairy.
Will this make me run to the bathroom?
No. This is a gentle daily capsule, not a laxative — it contains no harsh laxative ingredients and won't send you running to the bathroom.
Can I take this instead of a greens powder?
Yes. We packed these organic superfoods into an easy-to-swallow capsule, so you get the nutrition of a greens blend — including a controlled dose of natural iodine — without the grassy taste or the hassle of mixing powders.
Does this contain caffeine?
It contains a very small, naturally occurring amount from the Organic Green Tea Leaf, but it is not a high-stimulant product and will not cause jitters.
