Add the coconut water, filtered water, strawberries, honey, and sea salt to a blender.
Blend until completely smooth.
Taste and add a little more honey if desired.
Pour over ice and enjoy immediately.
Notes
Consistency: For a thinner drink, add an additional 2–4 ounces of cold water. Strain through a fine-mesh sieve if you prefer a smoother texture. Frozen strawberries can be used for a colder, slushier drink.
Sweetness: This drink is lightly sweetened. Add up to 2 teaspoons of honey for a sweeter, more sports-drink-like flavor.
Storage: Double it up and store covered in the refrigerator for up to 24 hours. Shake or stir before drinking.
