Hydration isn’t one-size-fits-all. Differences in sweat rate and electrolyte concentration mean that what works for one athlete may not work for another.
The Beverage Chart in the Nix Solo app is designed to help you compare hydration products against your individual sweat composition (mg/oz or mg/ml), allowing you to make more informed decisions about hydration during training.
The Beverage Chart is located at the bottom of the Sweat Profile tab within Nix Solo. It displays a range of hydration beverages plotted according to their electrolyte concentration in milligrams per ounce or milligrams per milliliter dependent on your profile preferences.
This allows you to:
Your unique sweat composition is also plotted directly on the chart, providing a clear reference point for comparison.
Sweat composition measures how many milligrams of electrolytes you lose per ounce (or milliliter) of sweat (mg/oz or mg/ml).
This value varies widely between individuals. Some athletes fall below 20 mg/oz (0.7 mg/ml), while others exceed 100 mg/oz (3.4 mg/ml). Because of this range, hydration strategies based on general recommendations often fall short.
With your Nix data, you can:
If your preferred drink isn’t listed, or if you want to add a custom drink, you can calculate its composition using the nutrition label:
This gives you the drink’s composition which can be compared directly to your sweat composition.
At the top of the chart, your sweat composition will be summarized and you see where it falls relative to the beverages displayed.
This serves as your reference point when evaluating different options and identifying drinks that most closely align with your needs.
Sweat composition can change depending on factors like temperature, humidity, and workout intensity.
Use the filter function within the Sweat Profile tab to view how your data changes across conditions and adjust your hydration decisions accordingly.
Each beverage is positioned based on its electrolyte concentration.
Selecting a drink allows you to view its composition based on total electrolytes, and by sodium specifically, to see how closely it aligns with your needs.
Note: Nix Preferred Partners are highlighted on the chart with a green dot and can be accessed directly from the drink card.
If a product you prefer doesn’t match your sweat composition, you can modify it.
The Custom Drink Calculator, available from each drink card, allows you to determine the appropriate product-to-water ratio to better match your individual sweat composition.
The Beverage Chart translates your sweat data into actionable guidance.
By comparing your sweat composition to the electrolyte concentration of different beverages, you can:
Over time, this approach supports a hydration strategy that aligns more closely with your individual physiology rather than relying on generalized recommendations.
