Does Nettle Have a Lot of Iron? A Comparative Look
Stinging nettle (Urtica dioica) has been a staple in traditional medicine and cuisine for centuries, valued for its potent nutritional benefits. For those seeking to boost their iron intake through plant-based sources, nettle often comes up as a promising candidate. The short answer to whether nettle has a lot of iron is a resounding yes; it is exceptionally rich in this mineral. In fact, numerous studies have shown that nettle contains more iron per 100g than spinach, a plant widely known for its iron content. This mineral density, along with a rich profile of other essential vitamins and minerals, firmly establishes nettle as a nutritional powerhouse.
The Rich Nutritional Profile of Nettle
The appeal of nettle goes far beyond just its high iron concentration. It is loaded with a wide array of vitamins and minerals that support overall health.
- Vitamins: Nettle is a fantastic source of vitamins A, C, K, and several B vitamins. The presence of vitamin C is particularly beneficial for iron absorption, as it significantly enhances the body's ability to take in non-heme iron from plant sources.
- Minerals: Beyond iron, nettle leaves are packed with calcium, magnesium, phosphorus, potassium, and sodium. The combination of these minerals provides a comprehensive boost to the body's mineral stores, which is why it has been used traditionally as a "spring tonic".
- Protein: During its peak season, nettle leaves can contain up to 25% protein, making it an excellent plant-based protein source. This high protein content, combined with its minerals, adds to its restorative properties.
- Antioxidants: The plant contains various bioactive compounds, including flavonoids and phenolic acids, which offer strong antioxidant and anti-inflammatory properties.
Comparing Nettle to Other Greens
To put nettle's iron content into perspective, a comparison with other common leafy greens is helpful. While specific iron values can vary based on factors like drying methods and growing conditions, the general consensus is that nettle provides a superior mineral profile.
| Nutrient (per 100g) | Stinging Nettle (Dried) | Spinach | Notes |
|---|---|---|---|
| Iron (mg) | 7.8 mg (or higher) | 4.1 mg | Nettle consistently shows significantly higher iron levels. |
| Calcium (mg) | 630 mg | 126 mg | Nettle is also a much better source of calcium. |
| Protein (g) | ~2.7 g | ~2.9 g | Protein content is comparable, but can vary. |
| Mineral Superiority | High levels of Fe, K, Mg, Mn, Ca, and Zn | Lower concentrations compared to nettle | Research shows nettle surpasses spinach in multiple mineral categories. |
Bioavailability of Nettle's Iron
The iron found in nettle is non-heme iron, the type found in all plant-based foods. While non-heme iron is not as easily absorbed as heme iron from animal sources, nettle's composition is uniquely beneficial. The herb naturally contains high levels of vitamin C, which acts as a powerful enhancer for non-heme iron absorption. This synergy means that the body is better equipped to utilize the iron provided by the plant itself, a clear advantage for those looking to increase their iron levels naturally.
However, it is important to note that the scientific evidence on the bioavailability of nettle's iron in human clinical trials is limited. Most information is based on its nutrient profile and traditional use rather than rigorous clinical validation, though its traditional use for treating anemia is well-documented.
How to Prepare and Consume Nettle Safely
The stinging hairs on nettle leaves are neutralized by heat, making the plant safe for consumption once cooked or dried. There are many ways to incorporate this nutritious herb into your diet:
- Nettle Tea: A simple and popular method involves drying the leaves and steeping them in hot water. A nourishing herbal infusion, which involves simmering the tea for a longer period, can extract even more minerals.
- Soups and Stews: Use nettle leaves as you would spinach. They can be added to soups and stews for an earthy, iron-rich boost.
- Green Smoothies: Add dried nettle powder to your morning smoothie for a convenient and nutrient-dense addition.
- Sautéed: Sauté fresh, young nettle leaves like spinach for a simple side dish.
- Pesto: Substitute basil with nettle to create a unique and mineral-rich pesto sauce.
Important Precautions
While nettle is generally safe for most people, certain precautions should be taken. Individuals with hemochromatosis, a condition causing excess iron in the body, should not consume nettle due to its high iron content. As with any new herbal remedy or dietary supplement, it is always recommended to consult a healthcare provider, especially for pregnant or breastfeeding women, or those on medication.
Conclusion: Nettle's Role in a Healthy Diet
In conclusion, stinging nettle is indeed a potent source of iron, containing significantly more than common alternatives like spinach. Its naturally high vitamin C content aids in the absorption of this non-heme iron, making it an effective food for supporting healthy iron levels and combating anemia. With its rich nutritional profile of vitamins, minerals, and protein, nettle offers a comprehensive range of health benefits beyond its iron content. By preparing it safely through cooking or drying, nettle can be a valuable and versatile addition to a nutrient-dense diet, whether consumed as a tea, in soups, or sautéed as a vegetable. Research on its nutritional properties continues to highlight its powerful health-enhancing effects, confirming its long-standing reputation as a valuable medicinal herb.

Can Dried Nettle Leaves Be Used to Make Tea?
Yes, dried nettle leaves can be steeped in hot water to make tea. This is a very common way to consume nettle, and the drying process effectively neutralizes the stinging hairs, making it safe.
Is Nettle a Better Source of Iron Than Spinach?
Based on comparative studies, nettle leaves often contain a higher concentration of iron per 100g than spinach. Additionally, nettle contains its own vitamin C, which enhances the absorption of its non-heme iron.
Does Nettle Help with Anemia?
Yes, due to its high iron content and the presence of vitamin C, nettle is traditionally used to combat anemia and is considered a blood-building herb. Its nutrients help stimulate red blood cell production.
Can You Eat Fresh Nettle Leaves?
No, you should not eat fresh nettle leaves raw because of the stinging hairs. The hairs must be neutralized by heat, either through cooking or drying, before consumption.
What is the Best Way to Absorb Iron from Nettle?
Consuming nettle along with other vitamin C-rich foods can enhance iron absorption. Since nettle naturally contains vitamin C, its iron is already more bioavailable, but a long-steeped infusion may extract more minerals.
What Other Nutrients are in Nettle?
In addition to iron, nettle is a rich source of vitamins A, C, K, and B vitamins, as well as minerals like calcium, magnesium, and potassium. It is also a good source of plant-based protein.
Are There Any Side Effects of Consuming Nettle?
Nettle is generally safe, but starting with small amounts is recommended. It is contraindicated for individuals with hemochromatosis (iron overload), and those on certain medications should consult a doctor before use.
How Do You Prepare Nettle to Avoid Being Stung?
To avoid being stung, always use gloves when handling fresh nettle. The stinging hairs are destroyed by heat, so cooking methods like boiling, steaming, or drying render the leaves harmless.
