2THIRTY vs Liquid I.V.: side-by-side on sugar, sodium, calories, and what each does beyond hydration. The clean comparison most reviews skip.
Both promise better hydration. One ships as a sugary stick pack; 2THIRTY ships as a 30-serving tub you scoop into any glass. From there they part ways fast — one is a sugar-loaded sports-drink replacement, the other is a zero-sugar functional mixer built for the morning after. Here's the side-by-side.
Liquid I.V. is built around CTT — sugar, sodium, potassium — to push fluid into your cells the same way pediatric oral rehydration salts do. 2THIRTY skips the 11g of sugar, keeps the sodium, and adds B12, amino acids, L-Theanine, and liver-support ingredients you won't find in Liquid I.V.

| Potassium | 150 mg | 380 mg |
| B-vitamins | B6 + B12 | B3, B5, B6, B12 |
| Amino acids | BCAAs + L-Theanine | None |
| Liver / pre-covery support | NAC, Milk Thistle, L-Glutathione | None |
| Sweetener | Stevia + monk fruit | Cane sugar + stevia |
| Day & Night modes | Yes | No |
| Format | 30-serving tub — one scoop per glass | Single-use stick packs |
| Price per serving (Club) | $1.33 | $1.50 |
Liquid I.V. still makes sense if you specifically want the higher sodium dose for endurance training, you don't mind 11g of sugar, and you want the widest possible store availability.
2THIRTY makes sense if you want hydration without the sugar crash, you also want energy / focus / liver support built in, and you want a mixer that fits a fasting, keto, or low-carb routine.
Pure salt replacement after a long ride or hot workout — Liquid I.V. has more sodium and potassium per serving. Daily hydration, fasted mornings, or the night before a big day — 2THIRTY does more in one scoop without the sugar.
It depends on the goal. For sugar-free daily hydration plus pre-covery and energy support, 2THIRTY does more in one scoop. For pure sodium replacement during heavy endurance training, Liquid I.V. has more sodium per serving but adds 11g of sugar to do it.
Liquid I.V. uses the Cellular Transport Technology (CTT) ratio of sodium, potassium, and glucose, which is the same principle as a pediatric oral rehydration salt. The sugar is functional — it helps drive fluid absorption — but it also means 11g of added sugar per serving.
Yes. 2THIRTY provides 300 mg of sodium plus BCAAs and B12 per serving, which covers most general training. For 90+ minute endurance sessions in the heat, you may want to add a second scoop or pair it with a salty snack.
2THIRTY Night Mode was designed specifically for this with NAC, Milk Thistle, and L-Glutathione for liver support. Liquid I.V. helps with rehydration but doesn't include any liver-support ingredients.
