Fasting changes what matters in an electrolyte powder. A product can have zero sugar and still be sweetened and flavored; another can be unflavored yet deliver far more potassium than a reader should add casually. Start with the ingredient list, then compare sodium, potassium, magnesium, and serving size.
LMNT Raw Unflavored is the simplest single-serve choice here: three mineral ingredients, no sweetener, and a clearly stated 1,000 milligrams of sodium per stick. Saltivate Raw Unflavored gives a different balance in a 90-serving jar. Neither is a universal daily prescription. The right amount depends on the length of the fast, the rest of your diet, activity, health conditions, and medical advice.
Short on time? For an unsweetened mineral-only stick, start with LMNT Raw Unflavored. For a scoopable jar with less sodium per serving, compare Saltivate Raw Unflavored. Read the current label before combining either with salt substitutes or another electrolyte product.
Quick Comparison
| Product | Format | Defining label detail | Best fit |
|---|---|---|---|
| LMNT Raw Unflavored | 30 sticks | 1,000 mg sodium; three mineral ingredients | Unsweetened, high-sodium single servings |
| Saltivate Raw Unflavored | 90-serving jar | 800 mg sodium; no sweetener or flavor | Unsweetened daily jar |
| Nutri-Align Fasting Salts Original | 400 g pouch | Sodium, potassium, magnesium salts only | Plain, scoopable fasting salts |
| Carnivore Electrolytes Unflavored | Powder tub | Unflavored, zero-sugar mineral mix | Minimal-flavor routines |
| Keto Vitals RAW Unflavored | 60-serving tub | Unflavored, sugar-free powder | Readers wanting a larger tub |
| Hi-Lyte K1000 Unflavored | 50-serving tub | 1,000 mg potassium; low-sodium design | Potassium-specific plans, with medical clearance where needed |
| Redmond Re-Lyte Unflavored | 30 sticks | 1,000 mg sodium; no sweetener or flavor | Unsweetened travel sticks |
| Venture Pal High Sodium | 16-stick variety pack | 1,000 mg sodium; flavored, stevia-sweetened | Zero-sugar flavored travel sticks |
| Keppi Raspberry Lemonade | 50-serving tub | Zero-sugar flavored mix | Readers prioritizing a flavored powder |
| Key Nutrients Lemonade | 90-serving tub | Electrolytes plus vitamins | Flavored general hydration rather than a minimalist fast |
The first seven are unflavored or unsweetened choices; the last three belong in a separate flavored, zero-sugar lane. Zero sugar does not make every powder suitable for every definition of fasting. Check the exact ingredients and decide what your particular fast permits.
The 10 Electrolyte Powders for Fasting
1. LMNT Raw Unflavored – Best Unsweetened Stick
LMNT Raw Unflavored, 30 Sticks
Best Unsweetened StickA straightforward sodium-forward stick without flavoring or sweetener; check your total sodium intake before making it a daily habit.
Pros
- Three mineral ingredients
- 1,000 mg sodium per stick
- Single-serve travel format
Cons
- High sodium is not appropriate for every reader
- Compare its per-serving cost with jars
LMNT lists salt, magnesium malate, and potassium chloride for Raw Unflavored. Its published amounts are 1,000 milligrams sodium, 200 milligrams potassium, and 60 milligrams magnesium per stick. That is an unusually easy label to compare with a food-and-drink plan: no proprietary electrolyte-blend weight to decode.
Choose it when single-serving portions and an unsweetened ingredient list matter more than the lowest cost per drink. Skip it if a clinician has asked you to limit sodium, or if you only wanted a light mineral addition for a short fast. Saltivate is the closest jar-format alternative in this list; it lists 800 milligrams sodium per serving rather than LMNT’s 1,000.
2. Saltivate Raw Unflavored – Best Unsweetened Jar
Saltivate Raw Unflavored, 90 Servings
Best Unsweetened JarAn unsweetened three-mineral powder with explicit amounts and a larger jar for regular users.
Pros
- 800 mg sodium, 240 mg potassium, and 60 mg magnesium per serving
- No sweetener or flavor
- 90-serving jar
Cons
- Jar is less convenient for travel than sticks
- Still a substantial sodium serving
Saltivate states 800 milligrams sodium, 240 milligrams potassium, and 60 milligrams magnesium per serving for its Raw Unflavored jar. The brand says this version has no sugar, flavoring, stevia, or maltodextrin. Its 90-serving container is the practical difference from LMNT’s 30 individual sticks.
It is a better fit for someone who prepares drinks at home and wants each mineral on the label. It is not an automatic low-sodium alternative: 800 milligrams still requires a place in your total intake. Compare the current serving cost and panel with LMNT before buying, especially if portability is worth paying for.
3. Nutri-Align Fasting Salts Original – Best Plain Mineral Pouch
Nutri-Align Fasting Salts Original, 400 g
Best Plain Mineral PouchA plain fasting-salts pouch for readers who prefer measuring their own portions instead of buying flavored sticks.
Pros
- Sodium, potassium, and magnesium mineral salts
- No flavor or sweetener
- 400 g pouch
Cons
- Requires measuring each portion
- Check current US seller and shipping terms
Nutri-Align’s Original powder uses sodium chloride, potassium chloride, and magnesium citrate. It is unflavored, sugar-free, and filler-free according to the manufacturer. The 400-gram pouch is a different buying proposition from fixed-dose sticks: you measure what you use and must follow its own serving directions.
This is the most direct choice for someone who wants three mineral salts without a drink flavor. Skip it if preportioned servings matter or if you need a familiar US domestic fulfillment option; check the current seller and shipping terms on the exact Amazon page. Do not estimate the mineral amount from a spoonful: use the current Supplement Facts panel and an accurate measure.
4. Carnivore Electrolytes Unflavored – Best Carnivore-Friendly Tub
Carnivore Electrolytes Unflavored Powder
Best Carnivore-Friendly TubAn unflavored mineral tub aimed at zero-sugar routines, with the current label controlling dose decisions.
Pros
- Unflavored powder
- Zero-sugar positioning
- Sodium, potassium, and magnesium blend
Cons
- The current panel needs a serving-by-serving mineral comparison
- Not a substitute for a clinician-directed electrolyte plan
The selected Amazon listing describes this Carnivore Electrolytes powder as an unflavored, zero-sugar blend of sodium, potassium, and magnesium. That makes it relevant to readers who do not want a sweet drink during their eating window or fast. It does not establish that its mineral proportions suit every fast.
Check the Supplement Facts panel for the current tub before choosing it over Nutri-Align or Saltivate. A changed serving size can make a seemingly cheaper container less economical per useful mineral dose. Skip this product if you need a precisely documented sodium target that the current listing does not show clearly.
5. Keto Vitals RAW Unflavored – Best Larger Unflavored Tub
Keto Vitals RAW Unflavored, 60 Servings
Best Larger Unflavored TubA 60-serving unflavored tub for buyers who prefer a scoopable powder to individual packets.
Pros
- Unflavored powder format
- Sugar-free positioning
- 60 servings stated for the selected tub
Cons
- Current mineral amounts need label confirmation
- Not a convenient preportioned stick
The selected RAW Unflavored listing is a 60-serving Keto Vitals powder, not a flavored Keto Vitals stick pack. That exact distinction matters when comparing ingredients: the brand sells many flavored and functional variants under similar names. The unflavored tub is the one to inspect for a simple fasting routine.
Do not assume that the mineral amounts or supporting ingredients from a flavored Keto Vitals product apply here. Read the RAW panel and compare its sodium and potassium with Saltivate before ordering. Skip it if you need a single stick you can take to work or if the current listing does not show a clear Supplement Facts image.
6. Hi-Lyte K1000 Unflavored – Best Potassium-Focused Mix
Hi-Lyte K1000 Unflavored, 50 Servings
Best Potassium-Focused MixA potassium-led powder for a specifically planned mineral intake, not a default substitute for sodium-forward mixes.
Pros
- 1,000 mg potassium stated per serving
- Unflavored and unsweetened variant
- 50 servings
Cons
- Not a high-sodium formula
- High potassium warrants extra care with reduced kidney function or certain medicines
Hi-Lyte K1000 is deliberately potassium-forward. The brand states 1,000 milligrams potassium per serving and describes this unflavored variant as low in sodium, with no sugar or stevia. That differs sharply from LMNT or Venture Pal, which lead with 1,000 milligrams sodium.
Choose K1000 only when its potassium-to-sodium balance fits your plan. If you have reduced kidney function or take medicines that affect potassium handling, consult your clinician before using a high-potassium supplement. If sodium is the mineral you intended to add, this product may be the wrong tool even though the container says “electrolytes.”
7. Redmond Re-Lyte Unflavored – Best Mineral-Only Travel Pouch
Redmond Re-Lyte Unflavored, 30 Sticks
Mineral-Only Travel PouchAn unsweetened stick with more potassium than LMNT Raw for readers who want a portable mineral-only option.
Pros
- No flavor or sweetener
- 1,000 mg sodium and 500 mg potassium per serving
- 30 individually packed sticks
Cons
- Higher potassium than LMNT Raw
- Check total mineral intake before combining products
Redmond’s Unflavored Re-Lyte stick pack contains 30 portions. The maker lists 1,000 milligrams sodium, 500 milligrams potassium, and 60 milligrams magnesium per serving. It omits the flavorings and sweeteners used in other Re-Lyte varieties, making the exact Unflavored pack the one to compare for a mineral-only fast.
Its sodium matches LMNT Raw, but the stated potassium is 300 milligrams higher. That difference matters more than which package is easier to carry. Skip Re-Lyte if you are restricting potassium, and check your diet, medicines, and other supplements before adding another mineral product.
8. Venture Pal High Sodium – Best Flavored Travel Variety
Venture Pal High Sodium Electrolyte Packets, 16 Sticks
Best Flavored Travel VarietyA high-sodium flavored variety pack for readers whose fasting approach permits sweetened zero-sugar drinks.
Pros
- 1,000 mg sodium per stick
- 16 individually packed servings
- Zero sugar
Cons
- Contains flavoring and stevia
- High sodium is not for every diet
Venture Pal’s 16-stick high-sodium variety states 1,000 milligrams sodium, 200 milligrams potassium, and 60 milligrams magnesium per packet. The manufacturer lists zero sugar and zero calories, along with natural flavor, citric acid, stevia, and vitamin C. That is a very different ingredient profile from LMNT Raw even though the sodium numbers match.
Pick it for portable flavored drinks, not for an unsweetened mineral-only fast. Skip it if flavoring or stevia is outside your fasting rules, or if you are limiting sodium. Confirm the 16-stick variety and its flavors on the Amazon detail page before checkout because Venture Pal sells several similarly named packs.
9. Keppi Raspberry Lemonade – Best Flavored Tub
Keppi Electrolytes Raspberry Lemonade, 50 Servings
Best Flavored TubA zero-sugar raspberry-lemonade tub for readers who prefer flavor and scoopable servings.
Pros
- 50-serving tub
- Zero-sugar label
- Sodium, potassium, magnesium, and calcium listed
Cons
- Flavored mix does not fit every strict fast
- Verify the current panel before comparing mineral doses
Keppi’s Raspberry Lemonade tub lists 50 servings and a blend that includes sodium, potassium, magnesium, and calcium. The official product page says it contains zero sugar. It is a flavored hydration powder, not a stand-in for a three-ingredient fasting salt.
Choose it when your fasting approach permits a flavored zero-sugar drink and you prefer a tub to packets. Skip it if you want no flavoring at all. Compare the actual Supplement Facts panel with the unflavored options here; a broad list of minerals does not tell you how much sodium or potassium a scoop delivers.
10. Key Nutrients Lemonade – Best Vitamin-Added Alternative
Key Nutrients Electrolyte Recovery Plus Lemonade, 90 Servings
Vitamin-Added AlternativeA flavored general-hydration powder with vitamins; use it only if the full ingredient list fits your fasting rules.
Pros
- 90-serving tub
- Zero-sugar positioning
- Electrolytes plus vitamins
Cons
- More ingredients than a plain mineral mix
- Stevia-sweetened flavor does not fit every fast
Key Nutrients’ Lemonade Electrolyte Recovery Plus is a 90-serving, flavored powder with electrolytes and added vitamins. That broader formula may suit everyday hydration, but the extras do not make it a better strict-fasting choice than a mineral-only powder.
The exact Lemonade listing was in stock on Amazon at our latest check, though stock and sellers can change. Skip it if you are intentionally keeping your fasting drink to water and mineral salts. Keppi is the simpler flavored-tub comparison; Nutri-Align is the plain-powder alternative.
How to Choose an Electrolyte Powder While Fasting
Decide what your fast permits
An unsweetened mineral mix and a flavored zero-sugar powder are not interchangeable for every fasting goal. If your rules allow only water and minerals, compare LMNT Raw, Saltivate, Nutri-Align, Carnivore, Keto Vitals RAW, Hi-Lyte K1000, and Redmond Re-Lyte Unflavored by their current ingredient panels. Venture Pal, Keppi, and Key Nutrients fit a more permissive zero-sugar-drink approach. Neither category is a license to assume the product is necessary for every fast.
Read sodium and potassium separately
LMNT Raw, Redmond Re-Lyte Unflavored, and Venture Pal each state 1,000 milligrams sodium per serving, while Hi-Lyte K1000 emphasizes 1,000 milligrams potassium. Redmond’s unsweetened stick also states 500 milligrams potassium, more than LMNT Raw’s 200. These are different formulations for different circumstances. The NIH Office of Dietary Supplements warns that reduced kidney function and some medicines can impair potassium excretion. If either applies to you, get individual medical advice before using high-potassium products or potassium-based salt substitutes.
Compare the serving you will actually use
Check the current serving size before comparing tubs with sticks. A 90-serving jar is only better value when its useful mineral amounts and your measuring habits fit. A single stick prevents on-the-go scooping, but may cost more per serving. Do not double a powder just to chase one mineral without adding up the others. The FitnessVolt Fasting Electrolyte Calculator is a separate planning tool, not a reason to ignore a product label or a clinician’s guidance.
FAQ
Do electrolyte powders break a fast?
Plain sodium, potassium, and magnesium salts add no meaningful calories. Flavored zero-sugar powders may contain sweeteners, acids, vitamins, or other ingredients that fall outside a stricter fasting rule even when the Nutrition Facts panel says zero sugar. Read the complete ingredient list and follow the rules of the fast you chose.
Do I need an electrolyte powder for a short fast?
Not automatically. A routine overnight or time-restricted fast is different from a prolonged fast, heavy sweating, illness, or a medically supervised protocol. A product page cannot determine your personal mineral needs. Consider your normal food, fluid, activity, and health context before adding a concentrated powder.
Which powder has no sweetener?
LMNT Raw Unflavored, Saltivate Raw Unflavored, and Nutri-Align Fasting Salts Original have the clearest plain-mineral ingredient lists in this group. Verify the exact flavor or variant on the listing: several brands sell flavored products under nearly identical names.
Is more potassium always better during fasting?
No. Hi-Lyte K1000 is a potassium-heavy formula, not an upgrade over sodium-forward products for everyone. Redmond Re-Lyte Unflavored also carries more potassium per stick than LMNT Raw. The NIH cautions that reduced kidney function and medicines such as ACE inhibitors and potassium-sparing diuretics can increase the risk from high potassium intake. Seek individual medical advice when those factors apply.
Bottom Line
LMNT Raw Unflavored is the clearest unsweetened stick choice. Saltivate Raw is a strong jar-format comparison, and Nutri-Align offers a plain three-salt pouch. Hi-Lyte K1000 calls for particular attention to potassium; Redmond Re-Lyte offers an unsweetened travel alternative with more potassium than LMNT. Venture Pal, Keppi, and Key Nutrients belong in a flavored zero-sugar lane, not a strict mineral-only one. Read the current package, account for every other electrolyte source, and choose the format and dose that match your actual circumstances.
