Every ingredient in Firmline has been intentionally selected as part of our ongoing product development. As we complete formulation and manufacturing, we'll publish the final Supplement Facts panel, serving information, and complete product specifications before launch.
Electrolyte support
| Ingredient | Why we're testing it |
|---|---|
| Sodium Citrate | Provides sodium and helps build the electrolyte profile while keeping the flavor smoother than a heavily salted drink. |
| Potassium Citrate | Adds potassium as part of the electrolyte blend being tested for the Lemon Lime formula. |
| Magnesium Citrate | Adds magnesium to the developing electrolyte blend. |
Performance support
| Ingredient | Why we're testing it |
|---|---|
| Taurine | Included in the current prototype as part of Firmline's broader muscle-performance formula. |
Lemon Lime flavor system
| Ingredient | Why we're testing it |
|---|---|
| True Lemon | Adds real lemon character to the current prototype while we refine the final beverage-grade flavor system. |
| True Lime | Adds a crisp lime note and helps balance the lemon profile. |
| Citric Acid | Creates bright citrus tartness and helps sharpen the Lemon Lime flavor. |
| Malic Acid | Adds a smoother, longer-lasting tartness to round out the citrus profile. |
| Allulose + Stevia + Monk Fruit Sweetener | The sweetener blend currently being tested to balance tartness without making the drink overly sweet. |
Current prototype ingredients are still being tested and may change before launch. Final ingredient amounts, Supplement Facts, serving information, and product specifications will be published once the formula is finalized.
