It’s 2pm and you’re nodding off. Time to get the next pot of coffee goin’, right? NO! Instead, give my energy smoothie a try. It’s part of my arsenal of natural energy boosters, full of whole food ingredients meant to give the body energy. And that’s energy without the jitters or the crash. In fact, I’m giving you a whole list of great natural energy drinks to help you feel your best and chase your passions all day long.

Natural energy boosters

While plants natural provide our bodies what they need to thrive, specific plants are super charged to boost our energy.

*These foods naturally contain caffeine or other naturally occurring stimulants. Be sure to use them in moderation

So what’s the criteria for a naturally energizing food? The foods on this list often contain lots of fiber, which helps the body break down food slowly as well as use more of it for energy. The energy smoothie below has 3 grams of fiber along with 16 grams of natural sugar.

Many of the above foods are also loaded with vitamins + nutrients, like B vitamins and amino acids. These help the body stay awake and alert as well as focused. Toss one of these delicious foods (maybe not the fish) into your next green smoothie and turn it into a natural energy drink.

Smoothie boosters

If you’ve already started drinking green smoothies, and you’re looking to supercharge the energy they give you, then I’ve got some tips.

First, I boost all my smoothies (including this energy smoothie) with plant based protein powder. Because I couldn’t find a clean + delicious one on the market, I made my own. Protein Smoothie Boost adds 10 grams of pure, clean protein as well as 4 grams of healthy fat and 7 grams of fiber.

Then I open up my freezer. Depending on what my body needs (energy, immunity, help with inflammation), I also have a freezer full of smoothie cubes on hand to help. Just toss a few of these cubes into your next smoothie for an instant boost.

Natural energy drinks

Along with green smoothies, I also have a few fav drinks to keep my energy up in a way that works for my body and not against it.

Chia Fresca– This is my go-to drink after a long run or hard workout. Because it’s full of natural electrolytes, this refreshing beverage helps me recover quickly. I recommend this to any athlete I know; it’s got some serious energy boosting power! Drink the energy smoothie below before a workout, then use this chia fresca for recovery.

Healthy coffee– When I’m not on a seasonal cleanse, I do enjoy a daily cup of coffee. What used to be a whole pot of coffee has turned into an intentional 1 cup per day. I buy quality coffee beans then use grass-fed butter + collagen powder. This is as much of an energy boost as it is a ritual. This cup of coffee lets my body know it’s time to wake up, then conquer the day.

If you want a bigger energy boost, then swap in 1/2 cup green tea or coconut water for the 1/2 cup water. Green tea is naturally caffeinated, while coconut water is nature’s gatorade.

    This may be my new go-to! Soooo good after a killer workout w/ protein powder added in. Next time I may also add some fresh ginger, too.

    The grapefruit flavor came through too much for me so I added frozen fruit cubes. Much better!

  12. Jeff says:

    Hi great recipes but a lot of them you are using far too much fruit , as a rule of thumb it should be 80% veg 20% fruit due to the sugar content of fruit.

    • SGS Rawkstar Amanda says:

      Hi Jeff

      Thanks for reaching out. Most of our recipes follow our Simple Green Smoothie Formula which is 3 cups fruit, 3 cups liquid base + 2 cups leafy greens for 2 servings. Too much sugar? Try turning our formula on its head + boost up those greens. Instead blend 2 cups fruit, 3 cups liquid base + 3 cups leafy greens. We’ve found that the more you blend, the more you crave those greens and end up moving towards lower fruit ratios.
