Wakame (Undaria pinnatifida) is a brown seaweed native to Asian waters and a culinary staple in Japan and Korea for centuries.
Found in miso soup, salads, and side dishes, wakame is prized for both its flavor and its dense nutritional value.
Wakame is harvested from the wild or cultivated, then typically blanched and sold dried or fresh.
Its subtle briny-sweet taste, tender texture, and high mineral content make it an increasingly popular superfood worldwide.

13 Impressive Health Benefits of Wakame
Including wakame in your diet can offer myriad advantages. Below, discover the scientific benefits of this ocean vegetable.
1. Low-Calorie, Nutrient-Dense Superfood
Wakame is low in calories but high in essential nutrients such as iodine, manganese, magnesium, calcium, and folate, making it ideal for nutrient-boosting without excessive calorie intake.
- Supports healthy metabolism and energy levels.
- Aids in meeting daily vitamin and mineral requirements with minimal calories.
2. Supports Proper Thyroid Function
Iodine is critical for healthy thyroid hormone production, affecting growth, metabolism, and cellular repair. Wakame is one of nature’s richest iodine sources, with 280% of the RDI per 10g serving.
- May help prevent hypothyroidism and related symptoms like fatigue or weight gain.
- Can partially address global iodine deficiencies when consumed moderately.
3. May Reduce Blood Pressure and Improve Heart Health
Animal and human studies suggest wakame can help lower blood pressure and cholesterol, supporting cardiovascular health.
- Contains heart-healthy omega-3s (EPA) that lower inflammation.
- Studies show wakame intake may reduce systolic blood pressure, especially in children and animals, though more research on adults is required.
4. Strengthens Bones and Teeth
Wakame provides calcium and magnesium, essential for bone density and dental health. 100g gives roughly 15% of our calcium RDI and 25% of magnesium RDI.
- Calcium fortifies bones and prevents osteoporosis.
- Magnesium enables calcium absorption and supports nerve function.

5. Promotes Healthy Skin and Hair
The high mineral and antioxidant content in wakame can improve skin elasticity, hydration, and hair growth by supporting collagen formation and cellular repair.
- Vitamins A, C, E combat oxidative damage and fight skin aging.
- Omega-3s and magnesium reduce inflammation and dryness.
6. Balances Hormones Naturally
Iodine, manganese, calcium, and iron in wakame help regulate hormones, especially those involved in menstrual cycles and thyroid health.
- Manganese and calcium ease PMS symptoms and hormonal imbalances.
- May support a smoother menstrual cycle for women.
7. May Aid in Weight Management
Some research indicates that compounds in wakame suppress fat accumulation and boost metabolism.
- Fucoxanthin, a pigment in brown seaweed, may help burn fat.
- Low-calorie, high-fiber content increases satiety and regulates appetite.
8. Boosts Immunity and Cellular Health
Wakame contains immune-strengthening minerals like zinc, selenium, copper, and vitamins that power white blood cell production and repair bodily tissues.
- Supports body’s defense against infections and diseases.
- Promotes effective wound healing and cell regeneration.
9. May Reduce the Risk of Some Cancers
Populations that regularly consume wakame (such as in Japan) have comparatively lower rates of certain cancers, including breast cancer. Iodine and unique seaweed phytochemicals (like fucoidan) may play a role.
- Iodine potentially inhibits or reverses tumor growth, as some studies have shown.
- Antioxidant-rich profile protects cells from DNA damage.
10. Supports Mental Health and Cognitive Function
Omega-3 fatty acids (like EPA) found in wakame are vital for brain function, mood regulation, and may help alleviate symptoms of depression, anxiety, and age-related cognitive decline.
- Feeds brain cells to support memory and clarity.
- Alleviates inflammation associated with mood swings and cognitive disorders.
11. Excellent For Vegan and Vegetarian Diets
Wakame offers plant-based iron, folate, and even small amounts of vitamin B12, which is rare in vegan diets.
- Folate is essential for fetal development and cell synthesis.
- B12 supports nerve and immune function.
12. May Improve Circulation and Lower Risk of Diabetes
Regular intake may promote better blood circulation by supplying iron and supporting blood vessel health, potentially reducing risk factors for diabetes.
- Helps oxygenate body tissues via iron-rich content.
- Magnesium aids in blood vessel relaxation and healthy blood flow.
13. Provides Antioxidant Protection
Antioxidants in wakame (vitamin A, C, E, carotenoids) protect cells from oxidative stress, aging, and environmental damage.
- Prevents premature skin aging and inflammation.
- Helps fight free radicals that may lead to chronic diseases.
How To Use Wakame
Wakame’s mild salty flavor and tender texture make it versatile in a variety of dishes.
