Frequently Asked Questions

Using the system is incredibly easy:

1 - Remove the Stage cartridge from package

2 - Shake the cartridge well

3 - Thread onto the Cirkul cap

4 - Fill bottle with water and thread on the cap

5 - Use the dial to adjust the flavor and electrolyte consumption

6 - Enjoy and make sure to recycle when done!

TIPS FOR BEST PERFORMANCE - Shaking the cartridge in between fill ups helps our electrolyte packed formula flow best. Also make sure that the small silicone valve under the cap has a fully cut "X" in it, high quality silicone has a knack for healing itself!

Once opened, you can leave a cartridge right on the bottle. It is not recommended to store below 40°F or above 90°F for extended periods of time.
At an average dial setting, 1 cartridge = 4 bottles of flavor, which equates to ~250mg of sodium/electrolytes per bottle.

Since consumption varies by user, the easiest way to measure your electrolyte intake is to divide the amount of electrolytes in one cartridge by the average number of bottles you are getting from a single cartridge.

Example, if you use a setting around 8-10 and get two bottles from one cartridge then you are consuming half the electrolytes in a cartridge per full bottle of water. 

The "Dial Your Performance" chart can be used as a reference to help you get started.

We engineered the cap to be functional and added some simple instructions to the "bridge" that connects it to the mouth piece.

1 - From the closed position, you can press this bridge to pop the cap open, allowing for one handed operation.

2 - This bridge also has a slit down the center, which allows it to be clipped over the fin on the dial to hold it out of the way.

If the cap is too cumbersome, you can simply cut it off with a pair of sharp scissors. 

If you are experiencing a vacuum in the bottle after taking a sip it means the small air valve is stuck closed.

1 - Remove the lid and flip it over.

2 - On the underside you will see a small rubber valve, simply manipulate this with your fingers a bit to pop it open.

3- Reinstall your lid and this valve should allow air to flow into the bottle while drinking and prevent any vacuum from occurring.

Nope - our blends have no artificial colorings (or flavors for that matter). We know that sometimes it’s hard to tell the difference between your Stage water and regular water, that’s why we recommend always having your branded bottle in hand.
Stevia Leaf Extract
Lemon Lime, Strawberry Watermelon, & Blackberry Twist have 5 calories per serving while Orange has 0.
  • 1000mg of Sodium
  • 250mg of Potassium
  • 140mg of Calcium

The amount of electrolytes is adjustable and personalized to what you need. Turn the dial to 0 for plain water and up to 10 for the most concentrated number of electrolytes. During a workout or race, your taste, we know that your needs for electrolytes vary and the Stage Hydration technology can provide exactly what you need.

You will notice a significant drop off in flavor immediately. Pro-tip: give the dial a quick turn to 10 to test if there's any left, if not - time to move onto the next flavor cartridge.
Since 1 flavor cartridge lasts you about 4 bottles, it comes down to about $1/bottle which is a highly cost effective way to stay hydrated and replenish your electrolytes.
Yes. Our Sips are well under the 3 oz limit, so you can bring them with you to stay hydrated and save money wherever your activity & travel takes you.
It can’t hurt to fill up on electrolytes throughout the day, but we also recommend checking out our other Cirkul flavors ( to consider trying if you’re looking for other benefits beyond added electrolytes.
Currently, we are just selling the bottles in the starter kits and then the replacement cartridges. If you would like a bottle please email for more information.
Shipping is free on all Stage Hydration orders.
Not currently, but we do have our eyes set on expansion into other countries in the future.
