Product Details
Plant Bladderwrack (Fucus vesiculosus) Origin Wild harvesting, Atlantic coast Extract type Hydroalcoholic liquid extract 1:1 Alcohol content 30% Vol. Available sizes 30 ml / 100 ml Dosage 1β2 times daily, 5-10 drops with a little water Bioavailability Hydroalcoholic extraction helps obtain a concentrated liquid extract.
Packaging Amber glass bottle with dropper β airtight & light-protected Storage Cool, dry, away from light. Refrigerate after opening. About the Plant

Fucus vesiculosus, the Bladderwrack, is a brown seaweed that calls the rocky coastlines of the world's oceans home. It owes its name to the characteristic air-filled bladders on its fronds, which help it float upright in the water and reach towards the sunlight.
For as long as humans have lived on coastlines, Bladderwrack has been an important part of their culture. It was valued not only as food ("sea vegetable"), but also in traditional herbal practice. People recognised its nourishing power early on and used it to support metabolism, long before they knew that its secret lay in its high content of iodine and other sea minerals.
Bioavailability
Our hydroalcoholic liquid extract (30% Vol.) ensures that the naturally occurring iodine and other active compounds can be effectively absorbed by the body.
The alcohol serves as a pure, natural "key": it gently dissolves the full spectrum of valuable compounds from the plant β both water-soluble and fat-soluble β making them optimally available to your body. At the same time, it provides natural preservation, allowing us to completely avoid artificial additives.
What We Focus On
Quality is not just a buzzword for us. In practice, this means:
- High-quality wild harvesting on the Atlantic coast
- Fucus vesiculosus β the species with a long tradition
- Extraction ratio 1:1 β maximum plant power
- No artificial colours or preservatives
- 100% vegan and plant-based
- Light-protected amber glass bottle with dropper
Frequently Asked Questions
How do I take the Bladderwrack Extract?
1β2 times daily, 5-10 drops with a little water. It can be taken independently of meals.
How long should I take the extract?
Bladderwrack can be taken in cycles over several weeks or long-term at a low dosage for iodine support. It is advisable to take breaks and listen to your body's needs.
Can I take the extract if I have thyroid conditions?
Due to the high iodine content, it is essential to consult a doctor before taking this extract if you have existing thyroid conditions (particularly hyperthyroidism or Hashimoto's thyroiditis).
Are there alternatives to Bladderwrack Extract?
If your focus is on general metabolic support, Fenugreek Extract is also an interesting, warming alternative from the plant world.
Is the extract suitable for children?
Our formula contains alcohol and is designed for adult needs. For this reason and as a general precaution, we advise against use by children, pregnant women, and nursing mothers.
Can I combine the extract with medication?
Due to the effect on thyroid function, it is essential to consult a doctor before taking this extract alongside thyroid medication. This is the only way to ensure a safe and optimal combination.
What does "Hydroalcoholic liquid extract 1:1" mean?
The 1:1 ratio means: 1 kg of fresh plant material is used to produce 1 kg of extract. Cheaper extracts (e.g. 1:5 or 1:10) use significantly less plant material. The lower the second number, the more concentrated and higher quality the extract.
Why does the extract contain alcohol?
High-quality alcohol serves as a pure, natural "key". It gently dissolves the full spectrum of valuable compounds from the plant and makes them optimally available to your body. It also provides natural preservation, allowing us to avoid artificial additives entirely.
Which size should I choose?
The 30 ml bottle is ideal for trying the product or as a travel companion. The 100 ml bottle is the best choice for regular use and courses β you save over 15%.
Important Notices
- Food supplements are not a substitute for a balanced diet.
- Do not exceed the recommended daily dose.
- Keep out of reach of children.
- If you have thyroid conditions (particularly hyperthyroidism or Hashimoto's), consult a doctor before use.
- If pregnant, breastfeeding, or taking medication, consult a doctor before use.
