A green smoothie packed with spinach and fruit can provide some serious health benefits. Smoothies are a convenient, delicious, and versatile way to pack in essential nutrients, and adding spinach to your smoothie is one of the easiest ways to supercharge its health benefits. Green smoothies are one of the best nutrient-dense drinks around - especially for those with a busy, on-the-go lifestyle.
Why Spinach in Smoothies?
It’s not always easy to get the daily 2 1/2 cups of fruits and vegetables that the American Cancer Society recommends to prevent cancer and disease. Thanks to blenders, you can boost your fruit and veggie intake by drinking them in a smoothie. Unlike juices, smoothies contain all that good fiber.
Smoothies that contain greens like spinach (or other vegetables) in addition to fruits are the best choice, as they tend to be lower in sugar and higher in fiber - while still tasting sweet.
Spinach is one of the most nutritionally-dense vegetables out there. It’s low in calories, but high in fiber, folate, calcium, and vitamins A, C, and K. It’s also rich in cancer-fighting antioxidants and plant compounds. It’s a great source of lutein and zeaxanthin, which are antioxidants that protect the eyes from damaging UV light and promote overall eye health.
Spinach is often hailed as a superfood-and for good reason. This leafy green is low in calories but incredibly rich in nutrients that support nearly every system in your body. Whether you enjoy it raw in salads, sautéed as a side, or blended into smoothies, spinach is a versatile and powerful addition to your daily meals.

As suggested in the 2010 Dietary Guidelines, fruits and vegetables need to be increased in our diets. While smoothies are a great source of fruit, they rarely include vegetables. Therefore, this would be a great opportunity to create delicious smoothies that use both fruits and vegetables.
The Nutritional Profile of Spinach
Spinach is loaded with vitamins and minerals that are essential for optimal health. Spinach is a low-calorie, nutrient-dense food that delivers a broad spectrum of vitamins and minerals. One of its standout nutrients is vitamin K, which plays a critical role in blood clotting and bone health. It’s also an excellent source of vitamin A (in the form of beta-carotene), which supports eye health, immune function, and skin integrity. Spinach is rich in folate, a B-vitamin crucial for DNA synthesis and cell growth, making it especially important during pregnancy. Spinach is a good source of dietary fiber, which aids digestion, helps maintain stable blood sugar levels, and promotes a feeling of fullness-making it a great food for weight management. Spinach contains a variety of antioxidants, including lutein, zeaxanthin, and quercetin. Lutein and zeaxanthin are particularly beneficial for eye health, helping to protect against age-related macular degeneration and cataracts. Some people worry about the iron in spinach being less bioavailable due to its oxalate content. While it’s true that oxalates can inhibit iron absorption, pairing spinach with vitamin C-rich foods (like strawberries, citrus, or bell peppers) can significantly enhance iron uptake. Spinach is one of the most nutrient-dense foods you can eat. It supports bone health, boosts immunity, protects your eyes, and helps keep your digestive system running smoothly.
Here are some of the key nutrients found in spinach:
- Vitamin A: Promotes healthy vision, skin, and immune function.
- Vitamin C: Acts as a powerful antioxidant and supports collagen production.
- Vitamin K: Essential for blood clotting and bone health.
- Folate: Crucial for cell growth and repair, especially during pregnancy.
- Iron: Supports the production of red blood cells and prevents anemia.
- Calcium: Strengthens bones and supports nerve and muscle function.
- Magnesium: Plays a role in energy production and muscle relaxation.
- Fiber: Aids digestion and promotes a healthy gut.
- Antioxidants: Compounds like lutein and zeaxanthin protect against oxidative stress and inflammation.
What makes spinach stand out is its versatility and ability to deliver these nutrients in a compact, easy-to-consume form.
Health Benefits of Adding Spinach to Smoothies

Boosts Energy Levels Naturally:
Spinach is rich in iron, a mineral that plays a critical role in the production of hemoglobin, which carries oxygen throughout your body. Adding spinach to your smoothie can help combat fatigue and improve energy levels, especially for those who experience low energy due to iron deficiency. Pair spinach with a vitamin C-rich fruit like oranges or strawberries to enhance iron absorption.
Promotes Healthy Digestion:
Thanks to its high fiber content, spinach supports digestive health by promoting regular bowel movements and preventing constipation. Fiber also feeds the good bacteria in your gut, contributing to a balanced microbiome. Including spinach in your smoothies is a simple way to sneak in extra fiber without altering the texture significantly.
Supports Bone Health:

Spinach is an excellent source of vitamin K, which is essential for maintaining strong bones. Vitamin K helps the body absorb calcium more effectively and supports bone mineral density. Pairing spinach with calcium-rich ingredients like almond milk or yogurt in your smoothies makes for a bone-strengthening beverage.
Enhances Skin Health:
Spinach is packed with antioxidants, including vitamins A and C, which promote healthy, glowing skin. Vitamin A supports cell turnover and helps maintain a clear complexion, while vitamin C boosts collagen production to keep skin firm and youthful. Regularly consuming spinach in smoothies can contribute to a natural, radiant glow.
Strengthens the Immune System:
The combination of vitamins A and C in spinach makes it a potent immune-boosting ingredient. Vitamin C supports the production of white blood cells, which are vital for fighting off infections, while vitamin A helps maintain the integrity of your skin and mucous membranes, which serve as the body’s first line of defense against pathogens.
Aids in Weight Management:
Low in calories and high in fiber, spinach is a great addition to smoothies for those looking to manage their weight. Fiber helps you feel full longer, reducing the likelihood of overeating. The high water content in spinach also contributes to hydration and a feeling of satiety.
Supports Heart Health:
Spinach contains potassium and nitrates, which can help regulate blood pressure and improve overall cardiovascular health. Potassium helps counteract the effects of sodium, while nitrates promote better blood flow by relaxing blood vessels. Regularly incorporating spinach into your diet can support a healthy heart. Spinach is rich in dietary nitrates which helps to dilate the arteries, allowing for better blood flow and lower blood pressure.
Improves Vision:
Spinach is rich in lutein and zeaxanthin, two antioxidants that are known to protect eye health. These compounds help filter harmful blue light and reduce the risk of age-related macular degeneration and cataracts. Adding spinach to your smoothie is an easy way to support long-term eye health. Research has demonstrated that sufficient amounts of lutein can prevent or improve age-related macular degeneration. This is the leading cause of age-related blindness and otherwise poor vision. In addition to a broad assortment of nutrients, spinach delivers important plant compounds such as the antioxidant lutein. Lutein supports eye health and heart health due to its anti-inflammatory properties.
Optimizing Lutein Absorption
To maximize the heart-healthy antioxidant lutein in a green spinach smoothie, try adding coconut milk or cow’s milk, a new study suggests. To get the best out of the antioxidants in spinach in a green smoothie use coconut milk, or medium- or high-fat milk in the drink, a new study suggests.
A new study compared 14 liquids commonly used in smoothies to determine which ones would be best at liberating lutein from spinach for absorption by the human intestine. It revealed that not all spinach-based green smoothies are equal. The findings show that spinach smoothies containing coconut milk with or without additives, and high-fat and medium-fat cow’s milk are best for liberating lutein. Coconut milk without additives increased lutein liberation by 42%, and with additives by 25%. High-fat cow milk increased lutein availability by 36%, while medium-fat cow milk did so by 30%. Soy milk surprisingly had the opposite effect, reducing lutein liberation by 61%. For smoothies with soy milk plus additives, the result was better at 40%. Almond milk and oat milk had no significant effect on lutein liberation. The study was recently published in MDPI.
To be absorbed efficiently by our digestive system, lutein requires a minimal amount of fat.
“While plant-based milks were found in this study to be lutein reducers, it is important to note that lutein is a fat-soluble antioxidant. This means it needs fat to be absorbed, so you may be able to enjoy these plant-based milks as long as you are adding in a heart-healthy fat to help with lutein absorption,” she said.
In addition, and beyond lutein liberation, fruits also deliver helpful nutrients in a smoothie. “Whole fruits that are rich in vitamin C like kiwi, mangoes, and strawberries can increase the absorption of plant-based iron found in spinach. It is best to use whole foods versus a fruit juice to avoid excess sugar intake that can increase inflammation in the body.”
Tips for Adding Spinach to Smoothies
If you’re new to adding spinach to smoothies, here are some tips to get started:
Start Small:
If you’re worried about the taste, start by adding a small handful of spinach to your smoothie. Gradually increase the amount as you get used to it. Spinach has a mild flavor that’s easily masked by fruits like bananas, mangoes, or berries.
Use Fresh or Frozen Spinach:
Both fresh and frozen spinach work well in smoothies. Frozen spinach can give your smoothie a creamier texture while extending the shelf life of your greens. If you opt for fresh spinach, be sure to wash it thoroughly before use. Cooking spinach can reduce its nutritional value, as can freezing, so raw, uncooked spinach in a smoothie offers the greatest health benefit.
Pair It with Complementary Ingredients:
Combine spinach with ingredients that enhance its benefits, such as:
- Citrus fruits (e.g., oranges, lemons) for added vitamin C.
- Healthy fats (e.g., avocado, chia seeds) to boost nutrient absorption.
- Protein sources (e.g., Greek yogurt, protein powder) for a balanced meal.
Blend It Well:
To avoid a gritty texture, blend spinach thoroughly with liquid and softer ingredients before adding frozen fruits or other dense items. A high-speed blender is ideal for achieving a smooth consistency.
