Forget "an apple a day keeps the doctor away." What you really want to reach for are oranges, papayas, mangos, pineapple, and other tropical fruits high in vitamin C! This essential vitamin boosts your immune response when it’s most important.[1] Plus, it’s a powerful antioxidant — and not just on its own. It helps regenerate other antioxidants in your body.[1]

Many people eat oranges to get a vitamin C boost; did you know that one orange contains 78 percent of your recommended daily value?[1] Yet you might be surprised that a lot of foods have even more vitamin C than oranges. We’re looking at you, kale and mango.

One of the easiest ways to get all that nutritious vitamin C power is to pack it all into a smoothie. We’ve created a "taste of the tropics" smoothie, full of banana, mango, orange, and lemon, with fresh raspberries to round it out, and a handful of kale for even more nutrition. There’s even a bonus boost from Global Healing’s new Vitamin C supplement.

A healthy diet is key to having a healthy immune system. Ideally, that diet is mostly or exclusively plant-based, gluten-free, and free of animal products. It’s also a delicious way to eat! Make all-natural raw fruit smoothies a regular part of your health regime.

Best Vitamin C Smoothie Recipe

This smoothie recipe is packed with vitamin C — it has 287.5 mg per serving! To get the highest level of the vitamin as well as antioxidants, use fresh fruits, because they're rich in fiber and nutrients.[2] Plus, they’re natural rather than processed, which is better for your body. The fruits in this smoothie aren’t just high in vitamin C, they also contain potent antioxidants. That means the smoothie is an excellent immune system booster. Your body will thank you.

You should find all of the fruits in this tropical-inspired smoothie in the produce section. However, if they’re out of season or unavailable, you can replace fresh with frozen for some or all of them. If you use frozen fruit, go easy on the ice, so it doesn’t get too thick. The kale adds C plus extra vitamins and minerals — namely, A, K, and B complex.

Why Vitamin C Is So Good for Your Health

There’s a reason so many people reach for a vitamin C supplement or eat high-vitamin C foods when they feel a bit under the weather. It’s an essential vitamin for your immune system — it will help you feel better in no time. That’s because vitamin C is a powerful antioxidant — and builds up other antioxidants in our systems, too, particularly vitamins A and E.[3]

Taking vitamin C supplements regularly can help keep you healthy. If you do feel under the weather, some experts have found it shortens the length of time you are down and out.[4] Vitamin C protects your cells from harmful free radicals by attaching to healthy white blood cells and helping them multiply.[5]

Vitamin C also boosts collagen formation — a protein building block of your entire body, forming and repairing connective tissues, including the cartilage in your joints.[6] Collagen is not only important for wound healing but also for an effective immune response.

Vitamin C supports lung function, too. A regular supplement may help you breathe easier. If you’ve got a respiratory bug or have overworked yourself, it helps you get more air with each breath.[7, 8]

Vitamin C works well with zinc to fight oxidative stress, not only helping respiratory symptoms, which zinc is known for,[9] but also keeping you looking and feeling younger longer.[10] and

Points to Remember

Vitamin C is a powerhouse vitamin for your health. Although most people associate oranges with this vitamin, mango, papaya, pineapple, and other tropical fruits are also high in C. Blend them into a delicious tropical smoothie full of healthy nutrients. Our vitamin C smoothie recipe brings a powerful punch of health, with mango, banana, raspberries, lemon juice, orange, and a bit of kale.

Fresh fruit is real food, rich in fiber and nutrients that your body wants. A plant-based diet is the best way to optimal health. You will get more vitamins and nutrients from your food if you choose organic options, and avoid meat and processed foods.

Vitamin C offers numerous health benefits! In addition to boosting your immune system and improving antioxidant levels in your blood, vitamin C can help you get sick less often, recover more quickly, and give your collagen levels a healthy boost. It also helps you be proactive against signs of aging. Vitamin C works together in your body with vitamins A and E, and zinc.

Get an even bigger boost from vitamin C with Global Healing’s new Organic Plant-Based Vitamin C liquid extract. One dropperful of the supplement (either in the smoothie or on its own) will help you feel even better than you already do.
