Bladderwrack (Fucus vesiculosus<\/i>) is a type of brown seaweed that\u2019s tied to traditional medicine. It\u2019s also known as rockweed, red fucus, dyers fucus, rock wrack, black tang, and bladder fucus (1<\/a>).<\/strong><\/p><\/blockquote>\n

Growing up to 35 inches (90 cm) tall, bladderwrack grows along the coastlines of the Atlantic and Pacific Oceans, the North and Baltic Seas, and various waters in Canada and the United States (<\/span>1<\/span><\/a>). <\/span>Traditional medicinal practices have used it for centuries to treat an array of conditions, such as iodine deficiency, obesity, joint pain, aging skin, digestive issues, urinary tract infection, and thyroid dysfunction, including hyperthyroidism, hypothyroidism, and goiter development. <\/span>Rich in vitamins, minerals, and antioxidants, many people believe that bladderwrack\u2019s impressive nutrient profile can provide health benefits, though critics argue the claims are ahead of the research (<\/span>1<\/span><\/a>).<\/span><\/p>\n

This article tells you all you need to know about bladderwrack, including its benefits, uses, and side effects.<\/span><\/p>\n

Bladderwrack Nutrition<\/b><\/h2>\n

For centuries, many cultures have consumed seaweed as part of their regular diet due to its impressive nutrient profile.<\/span><\/p>\n

Bladderwrack is a type of seaweed that\u2019s rich in vitamins and minerals, such as calcium, iodine, magnesium,\u00a0<\/span>potassium<\/span>, sodium, zinc, and vitamins A and C (<\/span>1<\/span><\/a>,\u00a0<\/span>2<\/span><\/a>). <\/span>It\u2019s also high in phytochemicals. These health-promoting plant compounds, which include phlorotannins and fucoxanthin, may help lower oxidative stress \u2014 an imbalance between free radical and antioxidant levels in your body (<\/span>3<\/span><\/a>,<\/span>4)<\/span><\/a><\/p>\n

Bladderwrack is high in\u00a0<\/span>fiber<\/span>, which can support a healthy gut. In particular, it\u2019s high in alginic acid and fucoidans, which have both been shown to have health-promoting properties (<\/span>1<\/span><\/a>,<\/span>\u00a0<\/span>2,<\/span><\/a>\u00a0<\/span>5<\/span><\/a>).<\/span><\/p>\n

Health Claims<\/b><\/h2>\n

Despite many bladderwrack-related health claims, limited evidence supports the use of bladderwrack for weight loss, arthritis, joint pain, fertility, and urinary tract infections. <\/span>Most bladderwrack research involves its effects on thyroid and skin health, as well as its anti-inflammatory properties.<\/span><\/p>\n

Thyroid Function<\/b><\/h2>\n

Bladderwrack contains\u00a0<\/span>high levels of iodine<\/span>, a trace element that supports thyroid health by producing the thyroid hormones triiodothyronine (T3) and thyroxine (T4). These hormones help regulate your metabolism and support proper growth and neurological development (<\/span>6,<\/span><\/a>\u00a0<\/span>7,<\/span><\/a>\u00a0<\/span>8<\/span><\/a>).<\/span><\/p>\n

Iodine deficiency can lead to low T3 and T4 levels and may ultimately cause health complications, such as a goiter and hypothyroidism \u2014 a condition characterized by symptoms like weight gain, fatigue, dry skin, and increased sensitivity to the cold (<\/span>9<\/span><\/a>,<\/span>10)<\/span><\/a>. <\/span>Though it\u2019s common in developing countries,<\/span>\u00a0<\/span>hypothyroidism<\/span>\u00a0<\/span>from iodine deficiency is rare in the United States and other industrialized nations. Rather, hypothyroidism is mostly related to an autoimmune disease known as Hashimoto\u2019s thyroiditis (<\/span>10,<\/span><\/a>\u00a0<\/span>11<\/span><\/a>).\u00a0 <\/span>Despite being a good dietary source of iodine \u2014 a mineral that can support thyroid health \u2014 taking bladderwrack supplements or eating large amounts of it may provide excessive amounts of iodine (<\/span>12<\/span><\/a>).\u00a0<\/span><\/p>\n

Most healthy individuals can safely tolerate excess iodine. However, those with thyroid disorders, such <\/span>as\u00a0<\/span>hyperthyroidism<\/span>\u00a0<\/span>or hypothyroidism, should exert caution, as it can lead to worsened symptoms, especially if iodine deficiency was not the root cause of the disorder (<\/span>10<\/span><\/a>,\u00a0<\/span>11<\/span><\/a>,\u00a0<\/span>12<\/span><\/a>). <\/span>To be safe, it\u2019s best to speak with your healthcare provider before taking bladderwrack supplements.<\/span><\/p>\n

Anti-inflammatory Effects<\/b><\/h2>\n

Bladderwrack is rich in\u00a0<\/span>antioxidants<\/span>, such as phlorotannins, fucoxanthin, alginic acid, fucoidans, and vitamins A and C (<\/span>4<\/span><\/a>,\u00a0<\/span>13<\/span><\/a>,\u00a0<\/span>14<\/span><\/a>).<\/span><\/p>\n

In particular, phlorotannins and fucoxanthin are known for their high antioxidant activity and ability to scavenge free radicals. Free radicals are harmful compounds that can damage cells and lead to chronic disease and premature aging (<\/span>15<\/span><\/a>,\u00a0<\/span>16<\/span><\/a>,\u00a0<\/span>17<\/span><\/a>,\u00a0<\/span>18<\/span><\/a>).<\/span><\/p>\n

Some test-tube and rat studies have shown that brown algae like bladderwrack offer promising\u00a0<\/span>anti-inflammatory<\/span>\u00a0<\/span>and may help reduce tumor growth, blood sugar levels, and the risk of heart disease (<\/span>19<\/span><\/a>,\u00a0<\/span>20<\/span><\/a>,\u00a0<\/span>21<\/span><\/a>,\u00a0<\/span>22<\/span><\/a>,\u00a0<\/span>23<\/span><\/a>). <\/span>Additionally, one large study in 40,707 men and 45,406 women found a 12% decreased risk of heart disease with the daily consumption of seaweed, which contains compounds that are similar to those in bladderwrack (<\/span>24<\/span><\/a>).<\/span><\/p>\n

Beyond this study and another one showing minor improvements in blood sugar control, few human trials exist. Though, in theory, bladderwrack may provide anti-inflammatory benefits, more research is needed (<\/span>25<\/span><\/a>).<\/span><\/p>\n

Skin Health<\/b><\/h2>\n

Bladderwrack has been used as a topical treatment for skin issues, such as\u00a0<\/span>cellulite<\/span>, skin aging, and burns. <\/span>Early research has shown that the antioxidants in bladderwrack, namely fucoidan, promote collagen synthesis in the skin, which may help improve the look of cellulite, increase skin healing, and delay premature skin aging.<\/span><\/p>\n

In the first phase of a two-phase study, applying bladderwrack extract to skin samples led to a 228% increase in collagen production, compared with no improvements in the control group (<\/span>26<\/span><\/a>).\u00a0<\/span><\/p>\n

In the second phase, a mixture of bladderwrack extract and other algae extracts was tested on human upper leg skin for 12 weeks. Compared with the placebo product, the algae mixture led to a significant decrease in cellulite appearance and fat thickness (<\/span>26<\/span><\/a>). <\/span>Other older studies using topical gels containing 1% bladderwrack extract were associated with an\u00a0<\/span>increase in collagen<\/span>\u00a0<\/span>production (<\/span>27<\/span><\/a>,<\/span>\u00a0<\/span>28<\/span><\/a>).\u00a0 <\/span>Also, bladderwrack\u2019s high antioxidant content has been linked to less collagen and elastin breakdown when applied to human skin samples. Preventing the breakdown of collagen and elastin is important for the appearance of youthful skin (<\/span>29<\/span><\/a>,<\/span>30<\/span><\/a>).<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
