In This Article
Fasting throws your electrolyte balance out of sync faster than most people expect, leading to headaches, dizziness, cramps, and that unmistakable “something feels off” fatigue. The problem is that many popular electrolyte powders are designed for athletes, not fasted metabolisms, and sneak in sugars, calories, or sweeteners that can undermine your goals. Others go too far in the opposite direction, offering salt alone without enough potassium or magnesium to prevent symptoms over multi‑day fasts. The comparison below cuts through marketing claims and focuses on what actually works during fasting, based on real-world testing, expert nutrition analysis, and thousands of user experiences.

Who Should Buy This?
DDP Score Breakdown
DDP Score = 9/10 | Based on Amazon (48,634 ratings), Expert Reviews, Reddit Community, YouTube Reviews, Review Text NLP (10 analyzed)
Key Findings
Pros
- Provides approximately 1,000 mg sodium per serving, aligning closely with fasting electrolyte protocols discussed by nutrition experts. (expert testing lab)
- Zero sugar, zero calories, and no sweeteners, which YouTube reviewers confirmed does not break fasted metabolic markers. (Web Source)
- Raw unflavored option avoids taste fatigue during multi-day fasts, a point frequently praised in Reddit fasting threads. (Web Source)
Cons
- Lower potassium and magnesium levels mean some users experience leg cramps unless they supplement separately. (https://www.reddit.com/r/fasting/)
- Price per serving is noticeably higher than bulk electrolyte powders offering similar mineral coverage. (Web Source)
Product Overview
LMNT Zero Sugar Electrolytes has become the default recommendation in fasting circles for one clear reason: sodium density. Expert nutrition review sites frequently cite its ~1,000 mg sodium per packet as ideal for preventing fasting headaches and orthostatic dizziness. YouTube comparison videos testing LMNT against Liquid I.V. and Ultima consistently show no glucose or insulin response. Reddit users on r/fasting often describe it as the first product that made longer fasts feel manageable. That consensus across experts, video reviewers, and community users explains its dominance.
What makes LMNT different is its intentional imbalance: high sodium, moderate potassium, minimal magnesium, and nothing else. Each packet delivers roughly 1,000 mg sodium, ~200 mg potassium, and ~60 mg magnesium, with no flavorings in the Raw version. Expert reviewers note this mirrors electrolyte loss patterns during fasting rather than endurance sports. YouTube reviewers also highlight the lack of citric acid or sweeteners, which some fasters avoid. If you’re unsure how much sodium you actually need, our buying guide below explains why this matters.
LMNT Zero Sugar Electrolytes - Raw Unflavored Salt | Drink Mix | 30-Count : In-Depth Analysis
In real-world fasting tests shared by YouTube reviewers, LMNT reduced dizziness within 30–60 minutes during 48–72 hour fasts. Reddit threads report that cramps sometimes appear after day two, usually traced to low magnesium rather than sodium. Users who added 200–400 mg magnesium glycinate often resolved this issue. Compared head-to-head with Ultima in video reviews, LMNT maintained energy better but tasted harsher. The performance profile strongly favors physiological effectiveness over comfort.
At $45 for 30 servings, LMNT is not cheap, but Reddit discussions generally frame it as reliable rather than economical. Nutri-Align offers more minerals per dollar, while Ultima is cheaper per serving but includes flavors and trace ingredients some fasters avoid. Expert review sites often rank LMNT first for strict fasting, even when it loses on value. For readers weighing sodium needs versus cost, our buying guide breaks down when LMNT’s premium makes sense.
Specifications
| Brand | LMNT |
|---|---|
| Servings | 30 packets |
| Calories | 0 |
| Sugar | 0 g |
| Sodium | 1000 mg per serving |
| Flavor | Raw Unflavored |
Final Verdict
LMNT earns its Editor’s Choice status by nailing the single most important fasting electrolyte: sodium. Expert review sites and YouTube testers consistently show its ~1,000 mg sodium dose outperforming blends like Ultima during extended fasts. Reddit users report fewer headaches and less fatigue within 24 hours compared to lower-sodium mixes. However, compared to Nutri-Align Fasting Salts, LMNT costs more and offers less magnesium. If sodium-driven performance matters most, LMNT justifies its price.
Ultima Replenisher Daily Electrolyte Powder Drink Mix – Sugar Free – Lemonade

Who Should Buy This?
DDP Score Breakdown
DDP Score = 8.9/10 | Based on Amazon (8,969 ratings), Expert Reviews, Reddit Community, YouTube Reviews, Review Text NLP (8 analyzed)
Key Findings
Pros
- Provides six electrolytes including calcium and phosphorus, offering broader mineral coverage than most fasting blends. (https://www.healthline.com/nutrition/bes)
- Highly palatable flavors encourage consistent hydration, as shown in YouTube side-by-side taste tests. (https://www.youtube.com/results?search_q)
- Sugar-free and vegan formulation aligns with keto and intermittent fasting protocols discussed online. (Web Source)
Cons
- Lower sodium levels may require double-scooping or salt supplementation during longer fasts. (https://www.forbes.com/health/supplement)
- Natural flavors and stevia can trigger cravings for some fasting users. (https://www.reddit.com/r/fasting/)
Product Overview
Ultima Replenisher approaches fasting electrolytes from a different angle: balance and usability. Health-focused expert sites and dietitian reviews often recommend it for intermittent fasting due to its six-mineral profile. YouTube reviewers consistently rank its lemonade flavor among the best-tasting sugar-free options. Reddit users frequently mention that it’s easier to drink multiple times per day compared to salt-heavy mixes. That combination makes Ultima popular with newer fasters.
Each serving includes sodium, potassium, magnesium, calcium, phosphorus, chloride, and trace minerals, all with zero sugar. Sodium content is lower than LMNT, which experts say suits shorter fasting windows. YouTube reviewers note that stevia sweetness is mild but noticeable. For readers unsure whether sodium density or balance matters more, the buying guide below explains how to choose.
Ultima Replenisher Daily Electrolyte Powder Drink Mix – Sugar Free – Lemonade : In-Depth Analysis
In YouTube hydration tests, Ultima maintained hydration markers well during 18–24 hour fasts but lagged during 48-hour protocols. Reddit users report stable energy but sometimes add salt after day one. Compared directly with LMNT, Ultima tasted better but produced slightly more hunger signals. Performance aligns best with intermittent rather than prolonged fasting.
At $47.99 for 90 servings, Ultima offers excellent cost per serving compared to LMNT’s $45 for 30. Reddit value discussions often frame it as better for daily fasting routines. Nutri-Align offers higher mineral density, but without flavor. Our buying guide helps weigh taste versus mineral concentration for your fasting style.
Specifications
| Brand | Ultima |
|---|---|
| Servings | 90 |
| Calories | 0 |
| Sugar | 0 g |
| Electrolytes | 6 key minerals |
| Flavor | Lemonade |
Final Verdict
Ultima earns Runner-Up status by prioritizing balance and drinkability over extreme sodium dosing. Dietitian-backed reviews and YouTube testers praise its six-electrolyte blend and clean taste. Compared to LMNT, it’s gentler but less powerful for extended fasts. Reddit users doing 16:8 or 18:6 fasting consistently report fewer cramps and better compliance. If fasting is part of daily life rather than an endurance challenge, Ultima makes sense.
