Coriander: Nutrition Facts and Health Benefits

Coriander (Coriandrum sativum L.) is a versatile herb celebrated for its vibrant flavor and rich nutritional profile. Both its fresh leaves (often called cilantro) and dried seeds are staples in global cuisines, but beyond taste, coriander offers a treasure trove of nutrients and health-promoting bioactives. Understanding the nutritional facts and health benefits of coriander can help you harness its full potential for culinary and wellness purposes.

Coriander Nutrition Facts

Coriander is more than just a kitchen staple—it's a storehouse of nutrients. Its leaves, seeds, and even roots each provide unique nutritional benefits, from essential vitamins and minerals to potent antioxidants and healthy fats. Whether sprinkled fresh over dishes or ground into spice blends, coriander brings both flavor and nourishment to the table.

Nutritional Overview of Coriander Parts

Coriander’s nutritional value differs depending on which part of the plant you use:

• Leaves: These are particularly rich in vitamins A, C, and K, and provide significant amounts of calcium (689 mg/100g) and magnesium (412 mg/100g). They also contain high levels of total phenolic and flavonoid compounds, which contribute to their antioxidant activity. The leaves are low in calories and fat, making them a nutrient-dense choice for garnishing and salads 1 3.

• Seeds: Coriander seeds stand out for their fiber, protein (13.1%), and mineral content, notably iron (15.46 mg/100g), zinc, and manganese. Seeds are also a primary source of coriander’s essential oils, especially linalool, which imparts their characteristic aroma and flavor 1 3 6.

• Whole Plant: Coriander overall is low in saturated fat but contains linoleic acid, a beneficial polyunsaturated fat. It is also a source of α-tocopherol (Vitamin E), which plays a role in antioxidant defense 1 6.

Vitamin and Mineral Content

• Vitamins: Coriander leaves are especially high in vitamin K, which is essential for blood clotting and bone health. They also provide vitamin C for immune function and vitamin A for vision and skin health 1 3.
• Minerals: Calcium and magnesium are abundant in the leaves, while seeds provide notable amounts of iron, zinc, and manganese. These minerals are vital for bone health, metabolic processes, and immune support 3.

Bioactive Compounds

• Essential Oils: Linalool is the dominant compound in coriander essential oil, especially in the seeds, and is responsible for many of its health benefits and its distinctive aroma 2 6.
• Phenolics and Flavonoids: Both leaves and seeds contain antioxidant compounds such as phenolics and flavonoids, which protect cells from oxidative damage 1 3.
• Other Phytochemicals: Coriander also boasts coumarins, terpenes, and other secondary metabolites that contribute to its health-promoting properties 2 4 6.

Coriander Health Benefits

Coriander’s value extends far beyond the kitchen. Thanks to its unique blend of nutrients and bioactive compounds, coriander has been traditionally used in herbal medicine and is now supported by scientific research for a variety of health benefits.

Antioxidant and Anti-inflammatory Effects

Coriander is rich in antioxidants, including phenolic compounds, flavonoids, and vitamin E. These compounds neutralize harmful free radicals, reducing cellular damage and inflammation. Regular intake of coriander may help lower the risk of chronic diseases linked to oxidative stress, such as heart disease and certain cancers 1 3 4 8.

• How it Works: The antioxidants in coriander scavenge free radicals, while its essential oils exhibit anti-inflammatory effects by modulating key pathways in the body 4 6 8.

Digestive Health

Coriander has a long history as a remedy for digestive complaints. Its essential oils act as carminatives (relieving flatulence) and spasmolytics (relieving muscle spasms), supporting healthy digestion and alleviating symptoms like bloating, indigestion, and abdominal pain 2 5.

• Traditional Uses: Coriander is used to treat stomach disorders, nausea, and even infections of the gut 2 5 8.
• Scientific Evidence: Animal studies confirm coriander’s ability to modulate gut motility and tone, supporting its traditional use for colic and diarrhea 5.

Blood Sugar and Metabolic Health

Emerging research shows coriander’s potential for managing blood sugar levels. The polyphenols and essential oils in coriander seeds and leaves have anti-diabetic effects, improving glucose metabolism and insulin sensitivity 1 6.

• Mechanisms: By enhancing insulin activity and inhibiting enzymes involved in carbohydrate breakdown, coriander may help control blood glucose levels 1 6.
• Practical Use: Incorporating coriander into the diet may be particularly useful for people at risk of, or managing, type 2 diabetes.

Heart Health

Coriander supports cardiovascular wellness in several ways:

• Blood Pressure: Seed extracts have demonstrated a blood pressure-lowering effect in animal models, likely due to vasodilation and diuretic properties 5 6.
• Cholesterol and Lipids: Coriander may help reduce total cholesterol and triglyceride levels, partly thanks to its fiber content and bioactive compounds 6.

Antimicrobial Properties

The essential oils in coriander, especially linalool, exhibit strong antimicrobial effects against a range of bacteria and fungi. This not only explains coriander’s traditional use as a food preservative, but also its potential in fighting infections 3 4 6.

• Culinary Benefit: Adding coriander can help extend the shelf life of foods and reduce the risk of foodborne illnesses 1 3.

Anxiety and Mood Support

Linalool, the dominant compound in coriander essential oil, has been shown to exert anxiolytic (anxiety-reducing) effects in animal studies. Traditionally, coriander has been used to promote calm and relieve stress 2 4 6.

Skin Health and Anti-Aging

Recent studies have highlighted coriander essential oil’s ability to inhibit enzymes that break down skin structure proteins. By increasing collagen content and reducing inflammation, coriander oil can help protect against skin aging and promote a youthful appearance 7.

Detoxification

Coriander contains compounds that can help facilitate the removal of heavy metals from the body—a process known as chelation. This detoxifying potential is especially valuable in environments with high heavy metal exposure 1 6.

Other Potential Benefits

• Pain Relief: Coriander has mild analgesic effects, making it useful for managing mild pain and discomfort 4.
• Neuroprotection: Some studies suggest coriander may protect brain cells and support cognitive health, potentially offering benefits in conditions like Alzheimer’s disease 4 6.
• Diuretic Effect: Coriander promotes urine production, which can aid in managing high blood pressure and fluid retention 5 6.

Conclusion

Coriander is far more than just a flavorful addition to your favorite dishes. Its leaves and seeds pack a nutritional punch, brimming with vitamins, minerals, antioxidants, and unique phytochemicals that support a variety of health benefits. From protecting your heart and supporting digestion to promoting healthy skin and helping detoxify the body, coriander earns its reputation as a culinary and medicinal powerhouse.
