Incredible Health Benefits of Mussels: Nutrition, Uses, and More
Incorporate these eco-friendly shellfish for a flavorful boost of protein and omega-3s.
Mussels are often overlooked in comparison to flashier seafood options, but they are nutritional powerhouses and offer a diverse range of health benefits. From boosting cardiovascular health to supporting brain function and sustainable living, mussels belong at the center of any healthy diet. In this comprehensive guide, we’ll explore the amazing health benefits of mussels, their nutritional composition, how to incorporate them into your diet, and answer your top questions about these nutrient-rich shellfish.
What Are Mussels?
Mussels are edible bivalve mollusks found both in freshwater and marine environments. Known for their tender flesh and subtly sweet flavor, they are commonly eaten around the world, particularly in Mediterranean, Asian, and coastal cuisines. Mussels are typically cooked by steaming, boiling, or baking and often served with flavorful sauces or in stews and pasta dishes.
Nutritional Profile of Mussels
Mussels are celebrated for their impressive nutritional value, delivering a potent combination of protein, essential fatty acids, vitamins, and minerals while being low in calories and fat.
- Protein: Mussels are rich in high-quality, complete protein containing all nine essential amino acids needed for muscle repair, immune function, and metabolic health. A standard 120g serving provides about 29 grams of protein.
- Omega-3 Fatty Acids: Especially EPA and DHA, crucial for brain and heart health. A 120g serving typically offers up to 1100mg of omega-3s.
- Vitamins: Mussels are high in vitamin B12 (nearly 980% of the daily requirement per serving), vitamin A, and vitamin C. They also offer small amounts of vitamins E and D.
- Minerals: Key minerals include iron, zinc, selenium, calcium, and iodine, all critical for healthy body function.
- Calories & Fat: Mussels are low in calories (about 103 in 120g) and fat, most of which is heart-healthy monounsaturated fat.
Key Health Benefits of Mussels
1. Superior Source of Lean Protein
Mussels deliver more protein per calorie than many other animal proteins, including beef. Their protein is not only abundant but highly digestible, supporting muscle growth, repair, and immune defense. This is an excellent food option for athletes, active individuals, or anyone looking to build or maintain muscle mass while managing caloric intake.
2. Supports Heart Health
The omega-3 fatty acids (EPA and DHA) in mussels help lower blood pressure, regulate heart rhythms, and reduce harmful triglycerides, collectively reducing the risk of cardiovascular disease. Regular consumption can help support blood vessel health and circulation, protecting against atherosclerosis, strokes, and heart attacks.
3. Fights Anemia and Boosts Energy
Mussels are an exceptional source of iron—vital for the production of red blood cells and oxygen transport throughout the body. Consuming mussels can help prevent iron-deficiency anemia, particularly in women, adolescents, and anyone at risk of low iron levels. They also provide vitamin B12, essential for energy metabolism and neurological function. One serving supplies hundreds of times the daily recommended B12 intake.
4. Promotes Brain and Nervous System Health
DHA and vitamin B12 are critical to brain health, aiding concentration, memory, and mood regulation. Regular intake of mussels may help preserve cognitive function during aging. Some studies suggest components in mussels may even help reduce the risk of neurodegenerative diseases.

5. Natural Anti-Inflammatory Effects
Green-lipped mussels, in particular, are noted for their anti-inflammatory properties. Omega-3s and other unique nutrients in mussels may help relieve symptoms of inflammatory conditions such as arthritis, asthma, and related disorders by reducing joint, airway, and tissue inflammation.
6. Supports Immune System Function
- Zinc: Essential for developing immune cells and fighting off infections.
- Vitamin A: Crucial for skin and mucous membrane integrity—our body’s first line of defense.
- Selenium: Supports antioxidant defenses and overall immune response.
These nutrients collectively help your body resist illness and recover faster from infections.
7. Promotes Healthy Skin, Eyes, and Thyroid
- Vitamin A: Supports vision and skin health.
- Selenium: Promotes healthy, glowing skin through its antioxidant action.
- Iodine: Regulates thyroid hormones for metabolism and energy balance.
8. Helps Maintain Healthy Weight
Mussels are nutrient-dense but low in calories and fat, making them suitable for weight management diets. Their high protein content also promotes satiety and reduces overall calorie intake at meals.
Environmental and Sustainability Benefits of Mussels
Beyond nutrition, mussels are a sustainable seafood choice:
- Low Carbon Footprint: Mussel farming produces significantly fewer greenhouse gases than terrestrial livestock.
- Water Quality Improvement: As filter feeders, mussels clean the water by removing excess nutrients and algae.
- Minimal Feed Required: Mussels feed naturally on plankton and require no additional wild fish or feed, making them eco-friendly.
Fresh vs. Canned Mussels: Which is Better?
Both fresh and canned mussels provide similar health benefits and nutrient content. Canning preserves mussels at peak freshness, maintaining their high levels of protein, omega-3s, and minerals. Choose varieties packed in extra-virgin olive oil for added heart health benefits. Note that canned mussels may be higher in sodium, so check labels if you are on a sodium-restricted diet.
How to Enjoy Mussels in Your Diet
- Steam fresh mussels with garlic, herbs, and white wine for a classic preparation.
- Add mussels to seafood stews, chowders, and pasta.
- Top salads and grain bowls with chilled, cooked mussels for protein.
- Use canned mussels as a quick snack or on crackers.
Mussels cook quickly and blend well with a variety of global cuisines, allowing endless creativity in the kitchen.
Potential Risks and Precautions
- Allergies: Those allergic to shellfish should avoid mussels.
- Sodium: Canned mussels may contain added salt; check nutrition information if limiting sodium.
- Sourcing: Always buy mussels from reputable sources to avoid contamination or foodborne illness.
