A Detailed Look at the Vitamins in 100g of Spinach
Spinach is widely celebrated for its dense nutritional profile, offering a low-calorie solution to boosting your daily vitamin intake. A standard 100-gram serving, which is roughly two-thirds of a cup of raw spinach, provides a remarkable array of essential vitamins. This section will break down the specific vitamins found in this quantity, based on data from reliable nutritional databases.
Vitamin K
Perhaps the most notable vitamin in 100g of spinach is Vitamin K. This leafy green is an exceptional source, providing over 400% of the recommended daily value in a single 100g serving. Vitamin K is crucial for several bodily functions, most famously its role in blood clotting. It is also essential for maintaining bone health and density. The concentration of Vitamin K in spinach makes it a key food for anyone needing to manage their intake of this nutrient, such as individuals on blood-thinning medication.
Vitamin A
Spinach is also a significant source of Vitamin A, delivered primarily through its high concentration of carotenoids, such as beta-carotene. When you consume spinach, your body converts these carotenoids into Vitamin A. A 100g serving typically provides over 50% of the daily value for Vitamin A. This fat-soluble vitamin plays a vital role in maintaining good vision, supporting immune function, and promoting healthy skin and hair.
Folate (Vitamin B9)
Another key vitamin found in 100g of spinach is folate, also known as Vitamin B9. A single serving can deliver close to 50% of your daily folate needs. This B-vitamin is critically important for cell growth, normal tissue function, and DNA formation. Folate is especially vital for pregnant women to help prevent neural tube defects in infants. The amount of folate in spinach is highest when consumed raw, as it can be sensitive to heat during cooking.
Vitamin C
Raw spinach is an excellent source of Vitamin C, with 100g providing about 30% of the daily value. As a powerful antioxidant, Vitamin C helps protect the body against damage from free radicals and is essential for a healthy immune system. It also plays a key role in the production of collagen, a protein that supports skin, hair, and nail health. The Vitamin C content is higher in raw spinach, as this vitamin is sensitive to heat.
Other B-Vitamins and Vitamin E
In addition to folate, spinach also contains a good amount of other B-vitamins, including riboflavin (B2) and Vitamin B6. These B-vitamins are important for energy metabolism and overall cellular function. A 100g serving also provides some Vitamin E, another potent antioxidant that helps protect cells from oxidative damage.
Comparison of Raw vs. Cooked Spinach Vitamins
The method of preparation significantly affects the vitamin content of spinach. While cooking can reduce levels of water-soluble vitamins like Vitamin C and folate, it can increase the bioavailability of fat-soluble vitamins and certain minerals.
| Nutrient | Raw Spinach (100g) | Cooked Spinach (100g) |
|---|---|---|
| Vitamin K | Very High (~402% DV) | Very High (Higher concentration) |
| Vitamin A (Carotenoids) | High (~52% DV) | High (Improved absorption) |
| Folate (B9) | High (~49% DV) | Moderate (Reduced by heat) |
| Vitamin C | High (~31% DV) | Low (Reduced by heat) |
This comparison highlights the benefits of consuming spinach in different forms. Raw spinach is superior for maximizing Vitamin C and folate, while cooked spinach makes fat-soluble nutrients like Vitamin A more readily available for the body to absorb.
Maximizing Your Spinach Nutrition
To get the most nutritional value from your spinach, consider these tips:
- Combine with healthy fats: Since vitamins A, E, and K are fat-soluble, pairing spinach with a healthy fat, like olive oil, avocado, or nuts, can significantly enhance absorption.
- Add a Vitamin C source: To boost the absorption of non-heme iron, include a source of Vitamin C with your spinach. A splash of lemon juice on a spinach salad or mixing spinach with berries in a smoothie are effective strategies.
- Mix it up: Incorporating both raw and cooked spinach into your diet ensures you get a wider spectrum of its vitamin content. Enjoy raw spinach in salads or sandwiches and cooked spinach in stir-fries, soups, or omelets.
Conclusion
In summary, 100g of spinach is a nutrient-dense food that offers a powerful punch of essential vitamins, particularly Vitamin K, Vitamin A (from carotenoids), folate (B9), and Vitamin C. The specific vitamin levels and bioavailability can be influenced by preparation, with raw spinach providing more Vitamin C and folate, while cooked spinach allows for better absorption of fat-soluble vitamins. By understanding and leveraging this nutritional information, you can easily incorporate spinach into a balanced diet to support overall health, from immune function and blood clotting to bone density and eye health. This simple leafy green truly earns its place as a nutritional superfood.

Important Considerations
While spinach is highly nutritious, it is also high in oxalates, which can inhibit the absorption of minerals like calcium and iron. People with a history of kidney stones may need to moderate their intake. Additionally, the high Vitamin K content can interfere with blood-thinning medications, so individuals on these drugs should consult a healthcare professional. For most people, however, the benefits of regularly consuming spinach far outweigh these minor considerations.
