Smoothies and juices are both popular ways to increase fruit and vegetable intake. While both provide important vitamins and minerals, there are some key differences that make juicing a healthier choice overall.
Juices are more nutrient dense than smoothies. When you juice fruits and vegetables, the process removes the fiber content, condensing all the nutrients into a smaller volume of liquid. This allows you to consume a larger amount of micronutrients in a single serving. For example, an 8 oz glass of juice may contain nutrients from 1-2 pounds of produce. Smoothies retain all the fiber from the whole fruits and veggies, so you don’t end up with the same concentrated nutrient profile.

As you can see from the table, juices contain a much higher percentage of your daily recommended intake of key vitamins and minerals per serving compared to smoothies.
Smoothies retain all of the fiber from the whole fruits and vegetables used in them. This is beneficial, as fiber is important for digestive health, heart health, stabilizing blood sugar levels, and maintaining a healthy weight. Juices contain little to no fiber since it is removed in the juicing process.

Smoothies provide a significant source of fiber, ranging from 4-5 grams per serving, while juices lack fiber almost completely. So if you are choosing between juice or smoothie, pick the smoothie if you are looking to increase fiber intake.
The lack of fiber in juices makes their nutrients easier to absorb. Fiber can bind to some minerals like zinc, calcium, and iron in the digestive tract, preventing full absorption. So while smoothies contain beneficial fiber, the trade-off is slightly reduced nutrient absorption capabilities.
Juices allow you to absorb more of their nutrient content. Without fiber present, the vitamins, minerals and phytonutrients can be completely assimilated by the body. This allows juices to provide more immediate nutritional benefits.
Smoothies often contain added sugars from fruit juices, syrups, honey, etc. While the sugar comes from natural sources, it can still quickly spike blood sugar when consumed in liquid form. All that sugar gets absorbed very fast without the fiber to slow it down.
Juices also contain natural fruit sugars, but they tend to use low sugar vegetables like cucumber, celery, spinach and kale. This balances out the glycemic load. For diabetics or those looking to maintain steady energy, juicing may be a better choice because it won’t dramatically impact blood sugar.

Compare a fruit smoothie with added juices or sweeteners to vegetable-based juices – the juices have about half the amount of sugar per serving.
Juices are primarily water, so they provide superior hydration compared to thick, creamy smoothies. After juicing, the pulp is discarded leaving only purified water and nutrients. Smoothies still contain all the fiber, which is beneficial but results in a thicker, less hydrating drink.
If you are exercising or outside in the heat for a prolonged period, juice is the better option to replenish fluids and electrolytes. The nutrients will be quickly absorbed as well.
Time and Convenience
Preparing smoothies is relatively fast and simple, especially if you use ready-made frozen fruit packs and leafy greens. Just throw everything in the blender. Juicing takes more time since you have to properly wash produce, chop it up to fit through the juicer, and then clean the machine afterwards.
In terms of convenience, smoothies win out. You can purchase pre-portioned smoothie packs to streamline the process even further. Juicing requires a bit more of a time investment on your part.
Juicers that extract a high yield of nutrients and juice from produce can be quite expensive. A good beginner’s juicer will set you back at least $100. High-end models designed for daily use can cost over $400.
Blenders are significantly cheaper across the board. You can find a quality blender suitable for smoothies starting around $40. Therefore smoothies may be the more budget friendly option.
You’ll have to factor in the price difference when deciding between juicing or blending at home.
Smoothies have a richer, thicker texture from the blended whole fruits and veggies. They taste sweeter as well. Juices have a lighter, more watery consistency. They also have a more potent vegetable flavor because that’s the primary ingredient.
If you enjoy both the texture and sweetness of smoothies packed with fruit, they may suit your palate better. Juices require a bit more of an acquired taste.
Weight Loss Benefits
Both juices and smoothies can help promote weight loss because they boost intake of healthy fruits and vegetables. However, replacing just one meal per day with a low-calorie green juice may have greater fat burning effects.
The body needs to work harder to metabolize the nutrients in juice without all the fiber. This slight stress on the system revs up your metabolism. Juices also provide pure hydration which improves liver and kidney function, facilitating better toxin removal.
For a quick shot of nutrients to energize you without a lot of calories, juice is the superior choice over smoothies when aiming to shed pounds.
In summary, juicing packs more nutrients per serving, absorbs better in the body, contains less sugar, and provides superior hydration compared to smoothies. However, smoothies retain fiber, which is also extremely important for health. The ideal combination is consuming fresh juices along with fiber-rich smoothies as part of a balanced diet. Choose juices when you want a quick nutrient boost or are looking to cleanse, and opt for smoothies when you want a fiber-filled meal replacement.
