Vitamin C Booster Smoothie


This vitamin C booster smoothie provides more than the daily RDA of vitamin C. And the flavor combo of grapefruit with pineapple and banana makes for a delicious, energizing drink!

Vitamin C makes most people think of oranges because they are known for their vitamin C content, however, there are other produce items like red bell peppers and strawberries that contain more vitamin C than an orange! Turns out, when comparing 1 cup of kale to 1 fresh orange, there’s more vitamin C in the kale. Fresh pineapple, grapefruit and bananas all have vitamin C as well.

So this smoothie combo contains no oranges, but still has well over the RDA for vitamin C. This is a good thing considering RDA is just the average daily dietary intake level that is sufficient to meet the nutrient requirement of most healthy individuals, not the optimal level. While research isn’t clear on whether vitamin C helps with the common cold,  scientific evidence does indicate that increased vitamin C intake is associated with reduced risk of chronic diseases.

In addition to having a high level of vitamin C, this smoothie also packs high levels of vitamin A and a good amount of calcium and iron. You also get a little healthy fat (9 grams), protein (8 grams) and fiber (8 grams). These components make the smoothie more filling and the healthy fat content helps your body absorb the fat soluble vitamins. Drink up!

I like having smoothies like this first thing in the morning for breakfast or as a mid-afternoon snack around 3 or 4PM when I start to get tired. It gives me an energy boost and helps me power through the rest of my day.Vitamin C Booster Green Smoothie served in a tall clear class with slice of pineapple, bunch of bananas in background.

Ingredients Needed

  • grapefruit – if you’re not using grapefruit juice make sure you’re using grapefruit segments! Segmenting the grapefruit removes the bitter pith and makes for a sweet and juicy smoothie without any bitter aftertaste.
  • frozen banana – frozen banana is the key to making smoothies with a creamy, thick texture. Just be sure to freeze your banana (unpeeled) before you want to make this smoothie.
  • pineapple – is packed with nutrients and an important enzyme called bromelain, which metabolizes protein, eases inflammation and decreases bloating. <— Yes please!
  • kale – I really like using Dole Power up Greens baby kale for this smoothie.
  • coconut oil – for the medium chain fatty acids, which are easily digested, burned for energy and promote blood sugar stabilization.
  • hemp seeds – for some fiber!

      This was my first time using grapefruit in a smoothie. It was good for something different and I always like to add greens to my smoothie. Thanks for another great recipe.

      My hubby and I just started making smoothies for breakfast. The key ingredient is always frozen banana.

        Totally agree! Frozen mango is also a good substitute if you happen to run out of frozen bananas one day. It adds the same sweetness and texture as the frozen banana, with mango flavor of course. 🙂

      Not a day goes by that I don’t eat a Dole banana with my breakfast!
