What is Caffeine?

Before we get into how to add caffeine to smoothies, let’s talk a little bit about what caffeine actually is. Caffeine is a central nervous system stimulant. It is found naturally in coffee beans, tea leaves, and cocoa beans – which is why we often associate it with those beverages. It’s also found in the leaves, seeds and and fruits of other plants.

Caffeine can also be found in a variety of manufactured products, such as most sodas, energy drinks, and even over-the-counter medications. It is added to some foods, like candy bars.

While caffeine is considered safe for most people when consumed in moderation (recommendation is below 400mg per day for healthy adults), it can have some side effects. These may include anxiety, jitters, headaches, and trouble sleeping. If you have any concerns about caffeine, be sure to speak with your doctor before adding it to your diet. (1)


Why Add Caffeine to a Smoothie?

Adding caffeine to a smoothie is a great way to get an extra boost of energy, especially if you are drinking it first thing in the morning or before a workout. It can help you to feel more alert and wake up your body and mind.

Caffeine can also help to improve your focus and concentration, which can be helpful if you are working on a project or need to be productive during the day.

In addition, some research suggests that caffeine may have positive effects on physical performance, including increased endurance and improved muscle contractions. (2)


6 Ways to Add Caffeine to Smoothies

Now that we know a little bit more about caffeine and why you might want to add it to a smoothie, let’s talk about how to do it!

Coffee

The most obvious way to add caffeine to a smoothie is with coffee. If you are a coffee drinker, this is probably the easiest and most convenient way to do it. Simply brew up a cup of coffee, let cool and add it to your smoothie ingredients.

You can also freeze coffee into cubes ahead of time and add those to your coffee smoothies. This is a great way to make sure your coffee smoothie has a really great texture and you won’t have to brew fresh coffee and cool it down every time you want a coffee smoothie.

If you’re a coffee lover it doesn’t really matter what type of coffee you add as long as it’s not hot – you don’t want to ruin your blender. (Plus a hot smoothie isn’t really that great!) So, if you prefer cold brew coffee, drip coffee, etc feel free to use what you like, except decaf because it contains no caffeine!

This smoothie is really delicious with just a small amount of whipped cream on top!

Tips for Using Coffee in Smoothies

If you are using fresh brewed coffee, be sure to let it cool before adding it to your smoothie. This will help to prevent your smoothie from becoming watered down.

You can also freeze coffee into coffee ice cubes ahead of time and add those to your smoothie. This is a great way to make sure your coffee doesn’t water down your smoothie.

If you are using cold brew coffee, you may want to add a little bit of water to thin it out before adding it to your smoothie.

You can use coffee grounds or instant coffee instead of brewed coffee if you prefer, or use leftover coffee.

Flavors that go well with coffee smoothies include nut butter such as peanut butter, cashew butter or almond butter, vanilla and chocolate. Adding in nut butter or protein powder will give you a great coffee protein smoothie.

Tea

Another way to add caffeine to a smoothie is with tea. Both green and black tea are good options. Just like with coffee, you’ll need to brew it first and then let it cool. Green tea is included in several of our weight loss smoothies because it is so good for the body and for metabolism.

Tea has a host of antioxidants and nutrients that can provide health benefits, and many varieties are also anti-inflammatory. So whether you prefer green tea, black tea or white tea, use it in place of any liquid called for in your smoothie recipe – just be sure not to use a decaffeinated blend!

As with coffee, you can also freeze tea into cubes ahead of time and use those to help blend a creamy, thick smoothie.

Another great way to use tea to add caffeine to a smoothie is with matcha powder. If you enjoy the taste of matcha, it’s a great way to add some energy into your smoothie!

Try our banana matcha smoothie recipe for a great way to combine matcha powder and smoothies.

Chocolate Weight Loss Smoothie

Chocolate

If you want to add a little bit of flavor to your smoothie while getting your caffeine fix, chocolate is a great option! You can use cocoa powder (check to ensure your brand contains caffeine) or chop up a chocolate bar and add it to your blender.

Chocolate milk is also a good option – just keep in mind that it will add some extra sugar to your smoothie. We recommend using a dark chocolate with at least 70% cacao for the healthiest option. Many bars will have caffeine content printed on the label, so check and find the best one for you.

Chocolate Smoothie Recipe

Ingredients:

1 cup almond milk

2 Tbsp dark chocolate

1 banana

1 scoop protein powder (optional)

Instructions:

Add all ingredients to a blender and blend until smooth. Enjoy immediately!

Tips for Using Chocolate in Smoothies

We recommend using a dark chocolate with at least 70% cacao for the healthiest option.

Cocoa powder can be a bit tricky to work with and it’s easy to use too much, so we recommend adding it slowly and tasting as you go to get the desired flavor.

You can also top your smoothie with chocolate shavings or chips.

Protein Powder with Caffeine

If you are looking for a way to get more protein and caffeine in your diet, there are several protein powders on the market that contain caffeine. These can be a great way to fuel your body before or after a workout.

Caffeine Powder

If you want to get a concentrated dose of caffeine, you can buy caffeine powder. This is often used by athletes or people who need an extra boost of energy. It is important to be very careful when using caffeine powder because it is very easy to overdose on it.

Start with a very small amount and increase gradually as needed. We recommend starting with no more than ¼ teaspoon and increasing from there as needed, with the best option being a kitchen scale to weigh it.

Ingredients:

¼ tsp caffeine powder

1 cup coconut milk

1 banana

Tips for Using Caffeine Powder in Smoothies

Caffeine powder is very concentrated and it is very easy to overdose, so start with a very small amount and increase gradually as needed.

A kitchen scale is the best way to measure caffeine powder, but if you don’t have one, use a very small spoon and be sure to level it off.

You can also buy caffeine in pill form and dissolve in water to use in your smoothie. This will ensure the amount of caffeine (ex. 100mg in each tablet).
