Although there is not a large amount of evidence currently, the evidence in humans has noted that 500 mg of bladderwrack (basic extract of the seaweed, not concentrated) appears to be bioactive. This is a lower dose than the 4,000 mg used in studies on Ascophyllum nodosum, and due to their similar composition the ideal range may be somewhere in between these two doses (or above 4,000 mg). *
Bladderwrack is available in many forms.
You can purchase dried, powdered, or encapsulated bladderwrack online or at some health food stores. It’s also available as a tea.
Due to limited research, there are no standard dosage recommendations for bladderwrack. However, most bladderwrack supplements come in 500-mg doses.
To make bladderwrack tea, steep one tea bag for 4–5 minutes in 8 ounces (236 mL) of hot water. Alternatively, add 1 teaspoon (5 mL) of dried bladderwrack to boiling water and allow it to simmer for 10–15 minutes.
Until more safety research is available, it’s best to limit your intake to no more than 2 cups (500 mL) per day to avoid consuming too much iodine and other active ingredients in bladderwrack. *
