The clearest difference is sugar and sweetener composition
Original Lemon Lime lists 11 g sugar per pictured stick, while Sugar-Free Lemon Lime lists 0 g and uses allulose with stevia. Both selected flavor panels list 500 mg sodium and 370 mg potassium. That makes ingredients and carbohydrate composition the main differences in this exact label pair.
The catalog packs also contain different numbers of sticks: 16 Original versus 14 Sugar-Free. Compare one serving first, then the pack count, so a larger pouch is not mistaken for a different serving size.

Pictured one-stick serving: 16 g powder.

Pictured one-stick serving: 13 g powder.
One stick, with the label basis made clear
| Line | Original | Sugar-Free |
|---|---|---|
| Pack / powder serving | 16 sticks; one 16 g stick | 14 sticks; one 13 g stick |
| Calories | 45 | 20 |
| Total carbohydrate | 11 g | 5 g |
| Total sugar / added sugar | 11 g /11 g | 0 g /0 g |
| Sodium / potassium | 500 /370 mg | 500 /370 mg |
| Selected sweetening ingredients | Cane sugar, dextrose and stevia | Allulose and stevia |
The current general Sugar-Free FAQ gives 510 mg sodium and 380 mg potassium, different from the pictured Lemon Lime panel. The table uses the flavor-specific 500/370 mg values. Follow the actual pack for the version being purchased.
Zero sugar does not mean identical ingredients
Allulose appears in the Sugar-Free formula even though total sugar is 0 g on the panel. Its 5 g carbohydrate figure is also different from zero. Read both Nutrition Facts and ingredients when comparing sweetener preferences.
Original’s sugar and dextrose are part of its actual formula, not a feature that can be mentally removed while leaving the rest of the drink unchanged. The right comparison is the finished labeled product against the other finished product.
Mineral similarity in these two panels does not establish identical taste, every vitamin amount or every ingredient. Nor does the word Sugar-Free tell you the complete allergen information. The full current package remains the source for that question.
Use one packet as directed
For a work or travel bottle, record the mixing volume before packing. The Sugar-Free Lemon Lime page directs one stick into 16 fl oz water. Check the Original pack’s directions as well rather than treating the powder gram weight as the water amount.
A bottle with clear volume markings makes the preparation easier to repeat. More water changes concentration, not the total minerals in an intact stick. Adding extra sticks is a different quantity, not simply a flavor adjustment.
Is Sugar-Free necessarily better for everyone?
The label establishes different sugar and sweetener composition. Personal nutrition, fluid or mineral guidance and ingredient preferences can determine which is relevant to a person’s routine.
Can the table be used for another flavor?
Use the exact flavor’s panel. The general FAQ discrepancy is a good example of why family-wide numbers can be less precise.
What if I want a different sodium amount?
Compare the actual one-serving mineral lines across named products. The LMNT/Ultima comparison shows a larger mineral-profile difference than this Original/Sugar-Free pair.
