Bladderwrack Health Benefits
1. Improves Gastrointestinal Function
Bladderwrack contains high levels of dietary fiber, which promotes gastrointestinal health. Dietary fiber helps regulate the intestinal flow and also stimulates the growth of gut-friendly microbiota.
2. Helps Manage Diabetes
Bladderwrack contains fucoidans, bioactive compounds with potent anti-diabetic properties. They can reduce glucose absorption into the bloodstream, increase serum insulin levels, and help manage diabetes. Animal studies found that oral intake of bladderwrack reduced fasting blood glucose levels.
3. Has Anticoagulant Properties
The fucoidans in bladderwrack make it an excellent anticoagulant. Animal studies found that fucoidans could mimic the action of heparin, a potent anticoagulant. This may reduce the risk of ischemic stroke by minimizing blood clotting tendency in people with a history of hypertension and diabetes. However, the exact mechanism of how it works is not yet clear and needs further research.
4. Has Antitumor Properties
Fucoidans have antitumor properties and are effective against breast cancer, colon cancer, and lung carcinoma cells.
5. Antiviral Properties
The fucoidans in bladderwrack can effectively inhibit poliovirus III, adenovirus III, ECHO6 virus, herpes simplex virus (HSV), cytomegalovirus (CMV), dengue virus. However, the exact mechanism remains unclear.

How To Take Bladderwrack And Recommended Dosage
Seaweeds, in general, have a fishy smell, which can be unpleasant for a few when consumed as they are or in powdered form. That is why bladderwrack and other seaweed supplements are available in capsules.
It is best to consult a doctor to determine the ideal dosage (usually, it does not exceed three capsules), depending on your health condition and nutritional requirements, as unregulated intake may cause side effects.
Side Effects Of Bladderwrack
Bladderwrack is possibly safe when taken in small amounts. But anecdotal evidence suggests that excess intake may cause a few side effects like:
- Nausea And Vomiting: Its unpleasant taste and odor may make you nauseous and cause vomiting.
- Diarrhea: A few people reported experiencing diarrhea and sticky stools after taking bladderwrack supplements. This might be due to bladderwrack’s nutrient-dense nature. You may also experience dehydration due to diarrhea. Hence, consume adequate amounts of fluids to combat this.
- Bloating: Excess consumption of bladderwrack may cause bloating and gastric pain, which may be due to the high fiber content. Stay hydrated to minimize this side effect.
- Tingling Sensation In The Throat: If you are allergic to bladderwrack, it may cause itching and tingling sensation in the throat.
- May Aggravate Acne: Excess consumption of bladderwrack may worsen acne due to its high iodine content. However, there is no research to prove the exact mechanism.
If you experience any of the symptoms, stop consuming bladderwrack supplements. If the effects persist for over three days, consult a doctor immediately.
Bladderwrack supplements are rich in nutrients and a great way to improve your overall health. They are especially beneficial if you have iodine deficiency, thyroid dysfunction, and diabetes. However, do not consume the supplements without consulting your doctor, as excess intake may cause adverse effects.
