I love using the natural power of electrolytes to boost energy, especially while training for new adventures. These natural electrolytes smoothie cubes are a great way to help replenish your body after a workout… and who doesn’t want to try a blue smoothie?!
What's in this post
Have you ever spent an active day outside, and failed to stay hydrated? Chances are your body didn’t receive enough natural electrolytes. That’s why I created a smoothie cube recipe designed to give your body more natural electrolytes. Say goodbye to that electrolyte imbalance, and hello to renewed energy!
What are Natural Electrolytes?
Electrolytes are minerals that are vital for the body to function normally. Lots of fruits and vegetables contain the electrolytes our bodies need… which is why you often read about them in my blog posts. As a runner + adventure seeker, I work hard to make sure I’ve got the nutrients I need to live my best life.
Electrolyte minerals include:
- calcium
- bicarbonate
- potassium
- sodium
- chloride
- phosphate
- magnesium
I love that plants contain these minerals and we can easily get them by adding more plants to our diet! Let’s fuel our bodies with food that works for us, not against us.
Ingredients For Natural Electrolyte Cubes
- Bananas: The natural base that adds potassium, sweetness, and quick energy. You can freeze bananas so they don’t overripe and save them for when you’re ready.
- Coconut water: Provides natural electrolytes and hydration without added sugar.
- Sea salt: Adds sodium to support fluid balance and electrolyte replenishment.
- Trace mineral drops (optional): Boost magnesium and trace minerals lost through sweat.
- Butterfly pea powder (optional): Adds antioxidants and a fun blue color.

Jen’s Free Soup Challenge
I’d love for you to soup it up with me! For 5 days, I’ll send you a daily veggie-packed soup that’s easy enough for a busy weeknight and makes enough to freeze and pull out all winter.
How Can We Boost Our Electrolytes?
During the hotter months of the year, one of our team members, Lindsey, likes to use ConcenTrace® Trace Minerals Drops. They add an extra boost of natural electrolytes on days when she’s doing a lot of work outside or perspiring more.
The liquid contains very concentrated levels of minerals sourced from concentrated seawater in Utah’s inland sea. Some home water filtration systems remove these minerals from the water, so this is an easy way to add them back.
A mere 20 drops will remineralize a gallon of water. Lindsey says she uses these drops to successfully prevent as well as treat muscle cramping in her legs and other extremities.
Workout remedies
While the below natural electrolytes smoothie cube recipe is great to have on hand, sometimes I need to take electrolytes with me on a long run. If I’m running more than 8 miles (especially in the Florida heat!) I’ve got some go-to ways to keep my body balanced as well as energized:
Skratch Labs sports hydration drink mix offers concentrated minerals that you just add to water. So you can rehydrate as well as replenish electrolytes at the same time. hydration
LMNT drink mix also focuses on a concentrated mix of minerals to recharge your body.
Both of these mixes are super small and can fit in a pocket or running pack, then used when needed.
Are sports drinks good for you?
Sports drinks have long been all the rage as ways to hydrate and replenish whether it’s during a sports game or other times of physical exertion. However, if you look closely at the labels you’ll find some unsavory ingredients including artificial flavors and colors.
In an attempt to appeal to a larger audience, there are even organic, dye-free sports drinks available now. Always read the ingredient list before purchase, and try to choose the most natural electrolyte drink you can find!
Natural Electrolytes Replenishers
There are plenty of fruits and vegetables that provide us with the necessary electrolytes through a varied, healthy diet.
But in the case of an imbalance, there are two excellent, 100% natural electrolyte replenishers that are loads better than sports drinks. Plus, they have fewer ingredients than hydration drink mixes. I’m talking about 100% pure coconut water and bananas.
Coconut water is an incredibly good source of potassium, it is also naturally sweet which can help provide natural, simple carbohydrates for energy.
Bananas are also known for their potassium, which is essential for maintaining normal blood pressure levels and heart function.
Here are some other plant based foods that help maintain as well as balance electrolytes naturally:
- Dill pickles
- vegetable juices (particularly tomato)
- lettuce and other leafy green vegetables (spinach is great!)
- olives
- potatoes with skin
- bananas
- nuts and seeds
- melon and cucumber
- citrus fruits
- broccoli
- sweet potatoes
- berries
- other produce with a high water content
In other words, green smoothies and plant-based meals are incredible ways to keep your body balanced + hydrated.

Recipe Card
Natural Electrolytes Smoothie Booster Cubes
Ingredients
- 5 bananas peeled and sliced
- 2 cup coconut water unsweetened, preferably not from concentrate
- 4 tsp Concentrace Trace Minerals optional
- 1-2 tsp butterfly pea powder optional
- pinch sea salt, unrefined
- pinch baking soda optional, to enhance color
Instructions
- Place the bananas, coconut water, sea salt and the trace minerals, butterfly pea powder and baking soda, if using, in a blender. Blend until smooth, adding a little more baking soda for a bluer color if needed.
- Pour into two standard 16-well ice cube trays and rap them on the counter a few times to release any bubbles. Freeze until firm, several hours or overnight.
- Pop the cubes out of the trays and transfer to an airtight, freezer-safe container.
- To use, add the cubes to your favorite smoothie in place of some of the fruit, or blend them on their own with water or coconut water for a quick drink.
Recipe Notes
- Color Tip: Butterfly pea powder gives the cubes their blue color; without it they’ll be light cream. Other fruit or vegetable powders make different colors.
- Baking Soda: Add the baking soda only a tiny pinch at a time, since too much tastes soapy.
- Ripeness Tip: Use ripe bananas with plenty of brown spots for the sweetest, creamiest cubes.
- Freezing: Store the cubes in an airtight, freezer-safe container for up to 3 months and blend them straight from frozen. Tuck a few into frozen smoothie packs so a quick blend is always ready.

I can’t wait to try this recipe out. With summer sports coming up, it will be an ideal replacement for my kids!
This is what I need for the summer! Where do you buy your butterfly pea powder? Thanks!
Great question Erin! We like using an organic butterfly pea powder, like this one on Amazon. Happy summer!
Can’t wait to try these! So many of the store bought electrolyte replacements taste horrible and have yucky chemicals. Thank you for a more natural way of getting my post-workout electrolytes in! 🙂
