Last updated: April 2026 | Research by Evident Health
The electrolyte market is on track to hit $82 billion by 2034, nearly doubling from its current $40 billion valuation. That kind of growth attracts everyone: pharmaceutical giants, Silicon Valley startups, Instagram influencers, and multi-level marketing companies. The result is a category overflowing with products that look similar on the shelf but differ dramatically under the label.
We spent four months evaluating 57 electrolyte powders, concentrates, and drink mixes. We pulled apart ingredient lists, traced mineral sources, verified third-party testing claims, checked for heavy metals and PFAS contamination data, and calculated cost per serving down to the penny. What we found was sobering: 75% of products contain "natural flavors" (an umbrella term that can hide hundreds of undisclosed compounds), most use the cheapest available mineral forms, and sodium content varies by a factor of 20x across the category. Several products marketed as "clean" or "natural" have confirmed contamination issues.
Here are the products that actually earned their claims, the ones that did not, and exactly how we scored all 57.
How We Tested
The Product Set
We evaluated 57 products across three segments: 18 market leaders (the household names), 20 clean/premium brands (the health-conscious DTC favorites), and 19 specialty and niche products (medical-grade ORS, athlete-specific, influencer brands, MLM companies, and emerging players). Three brands had two entries where meaningfully different formulations warranted separate evaluation: LMNT (flavored vs. Raw Unflavored, which has a confirmed lead issue), Nuun (Sport vs. Rest), and Liquid I.V. (original vs. sugar-free).
Scoring Framework
Every product was scored across five dimensions:
Formulation Purity (35%) -- No artificial sweeteners, no artificial flavors or colors, no "natural flavors," no fillers like maltodextrin or silicon dioxide, transparent labeling, clean mineral sources. This is the highest-weighted dimension because ingredient quality is what separates a good electrolyte from a mediocre one wearing good branding.
Electrolyte Profile (25%) -- Completeness (does it include sodium, potassium, magnesium, and calcium?), adequate amounts (not token doses), and source quality. We penalize magnesium oxide (4-15% bioavailability) and reward chelated or citrate forms that your body can actually absorb.
Testing & Transparency (20%) -- Third-party certifications (NSF Certified for Sport, Informed Sport, ConsumerLab), published Certificates of Analysis, verified heavy metals testing. Claiming to test is not the same as proving it.
Trust & Reputation (12%) -- Amazon ratings and review volume, brand track record, red flags (lawsuits, contamination findings, misleading marketing), MLM status.
Value (8%) -- Price per serving, return policy, subscription discounts, sample availability. Weighted lowest because a cheap product with bad ingredients is no bargain.
Bonuses and Penalties
Products that hit every clean label signal -- no natural flavors, no artificial anything, no fillers, transparent labeling -- earned a +1.0 clean label bonus. Products with confirmed contamination received cross-cutting penalties: -3.0 for verified lead or arsenic, -2.0 for confirmed PFAS.
Every data point was verified against brand websites, Amazon listings, FDA databases, and BBB profiles. For the top 20 products, we independently verified key claims.
Our Top Picks
#1. Needed Hydration Support -- 8.7/10
$1.53/serving | 30 servings | Powder
Needed earned the top spot by combining a flawless clean label with a thoughtfully balanced electrolyte profile. Sweetened with monk fruit extract and flavored with real lemon oil and lemon juice -- not "natural flavors" -- it is one of the few products in the entire category where every single ingredient is recognizable and purposeful.
The electrolyte profile delivers 250mg sodium, 250mg potassium (a balanced 1:1 ratio), 150mg magnesium citrate (a bioavailable form at a meaningful dose), and 315mg chloride, plus ConcenTrace trace minerals from seawater. The brand tests every batch at accredited third-party labs for potency, pesticides, heavy metals, microbes, and allergens, and holds Clean Label Project certification.
Originally formulated for pregnancy and lactation -- the brand was founded in 2017 and focuses exclusively on prenatal nutrition -- the formulation is equally strong for general daily hydration. The only real tradeoff is price: $1.53 per serving puts it at the premium end of the market. But when you account for the complete absence of shortcuts in the formulation, the cost reflects what clean ingredients actually cost.
Standout: Perfect clean label (zero natural flavors, zero fillers) + verified batch testing + Clean Label Project certified.
#2. LyteShow Electrolyte Concentrate -- 8.1/10
$0.50/serving | 40 servings | Liquid concentrate
LyteShow is the purest electrolyte product we reviewed. The entire ingredient list: purified water, low-sodium sea mineral concentrate, citric acid (from non-GMO plant sources), potassium chloride, zinc sulfate. Five ingredients. Zero additives, zero sweeteners, zero flavors, zero colors. Nothing to hide because there is nothing in there except minerals.
The concentrate format means you add it to water (or any drink) yourself. It has a subtle mineral taste that most people find inoffensive, especially when mixed into flavored beverages. At $0.50 per serving with 10,893 Amazon reviews averaging 4.6 stars, LyteShow combines radical ingredient simplicity with proven consumer satisfaction and outstanding value.
The tradeoff is electrolyte density. Sodium is relatively low at 125mg per serving, and potassium (130mg) and magnesium (40mg) are moderate. For daily hydration maintenance, this is fine. For heavy sweat loss or athletic performance, you will want something with more sodium.
Standout: The cleanest ingredient list in the entire category -- 5 ingredients, zero additives of any kind.
#3. NormaLyte PURE -- 8.1/10
$1.58/serving | 6 servings per pack | Powder
NormaLyte PURE is not a wellness product. It is a medical-grade oral rehydration solution built to the World Health Organization's exact formula specifications, and it is the product of choice in the POTS and dysautonomia community for a reason: it works when hydration is not a lifestyle choice but a medical necessity.
The formula contains just five ingredients: sodium chloride, sodium citrate, potassium chloride, dextrose, and trisodium citrate. The 6.75g of dextrose is not a sweetener -- it is functionally required for the sodium-glucose co-transport mechanism that makes ORS solutions dramatically more effective at rehydrating than water alone. This is the same science behind every ORS used in hospitals and cholera treatment worldwide.
With 862mg sodium and 393mg potassium per serving, NormaLyte PURE delivers serious electrolyte density. It contains no magnesium or calcium, but that is by design -- the WHO formula is optimized specifically for sodium-driven rehydration, not general mineral supplementation.
Standout: WHO-formula medical-grade ORS. FSA/HSA eligible. The clinical standard for serious rehydration.
#4. Skratch Labs Sport Hydration Drink Mix -- 8.0/10
$1.10/serving | 20 servings | Powder
Founded in 2012 by Dr. Allen Lim, an exercise physiologist who worked with professional cycling teams, Skratch Labs built its reputation on one principle: real food. The ingredient list reads like a recipe, not a chemistry experiment -- cane sugar, sodium citrate, dextrose, citric acid, calcium citrate, magnesium carbonate, potassium citrate, lemon oil, lime oil, lemon juice, lime juice, and ascorbic acid. No "natural flavors." Actual fruit.
The 19g of sugar per serving is intentional. Skratch is designed as a combined fuel and hydration product for endurance athletes, using a dual glucose-fructose transport system for sustained energy during exercise. This is not a daily zero-calorie hydration supplement -- it is engineered for performance during activity. The electrolyte profile (400mg sodium, 100mg potassium, 50mg magnesium, 50mg calcium) is solid for its purpose, with all four major electrolytes represented in citrate forms for good absorption.
With 81% positive sentiment on Reddit and 15,000+ Amazon reviews at 4.6 stars, Skratch has built deep credibility in the endurance community through actual performance, not influencer marketing.
Standout: Real fruit flavoring (actual lemon oil and lime juice, not "natural flavors"). The endurance athlete's electrolyte.
#5. NOOMA Hydrating Electrolyte Mixes -- 7.9/10
$2.00/serving | 20 servings | Powder
NOOMA -- short for "No More Artificials" -- was founded by two former professional hockey players in Cleveland, and the name captures the brand philosophy. USDA Organic certified, B Corp certified, and built on a coconut water base with Himalayan pink salt and organic stevia. The flavor comes from organic fruit juices and cocoa, not extracts labeled "natural flavors."
The electrolyte profile is noteworthy for its high potassium (420mg, sourced naturally from coconut water) and adequate sodium (340mg from Himalayan salt), though magnesium is low at 20mg. The USDA Organic certification is rare in the electrolyte space and covers ingredient sourcing beyond what most brands verify.
At $2.00 per serving, NOOMA is the most expensive product in our top eight. The premium reflects organic sourcing and B Corp overhead rather than inflated margins, but price-sensitive buyers should look elsewhere. The low magnesium also means NOOMA works better as a sodium-potassium replenisher than as a complete electrolyte solution.
Standout: USDA Organic + B Corp certified. One of the few truly organic electrolyte powders on the market.
#6. Transparent Labs Hydrate -- 7.6/10
$0.75/serving | 40 servings | Powder
Transparent Labs is the product that fitness reviewers consistently rank first, and the formulation justifies the praise. Informed Sport certified (banned substance testing for athletes), published Certificates of Analysis, TRAACS chelated calcium bisglycinate (one of the most bioavailable calcium forms available), Aquamin marine-source magnesium, and a solid 500mg sodium from sodium citrate and Himalayan rock salt.
The formula goes beyond basic electrolytes with 1,000mg taurine (an amino acid that supports hydration at the cellular level) and 500mg organic coconut water powder. At $0.75 per serving with 40 servings per container, the value proposition is strong for the quality tier.
The reason it is not ranked higher: natural flavors. Transparent Labs is transparent about doses, mineral forms, and testing -- but the flavored varieties still use "natural flavors" rather than real fruit. In a category where 75% of products rely on this catch-all term, Transparent Labs is in the majority, but for a brand built on transparency, it is a notable gap.
Standout: Informed Sport certified + published COAs + TRAACS chelated minerals. The most verified product in our top eight.
#7. Redmond Re-Lyte Hydration -- 7.5/10
$0.77/serving | 60 servings | Powder
Redmond has been mining ancient sea salt in Utah since 1958, and Re-Lyte leverages that heritage ingredient as its foundation. The Real Salt provides 810mg sodium plus 60+ naturally occurring trace minerals -- a genuine differentiator that most competitors cannot replicate with synthetic mineral blends.
The electrolyte profile is one of the most complete we reviewed: 810mg sodium, 400mg potassium (as citrate), 50mg magnesium from dual bioavailable forms (malate and glycinate), and 60mg calcium. The dual-form magnesium approach is smart -- malate supports energy production while glycinate is calming and well-absorbed. At $0.77 per serving across 60 servings, the price-to-quality ratio is among the best in the category.
Re-Lyte uses natural flavors sourced from dehydrated fruit and stevia for sweetening. The "natural flavors" prevent it from earning a perfect clean label score, though Redmond specifies their source (dehydrated fruit), which is more transparent than most brands. Calcium carbonate is the least bioavailable form they could have chosen -- a small but real formulation weakness.
Standout: Ancient Real Salt with 60+ trace minerals + dual-form bioavailable magnesium. Excellent value at $0.77/serving.
#8. Trioral ORS -- 7.5/10
$0.30/serving | ~100 servings | Powder
Trioral is what electrolyte supplementation looks like when you strip away every shred of marketing, branding, and flavor innovation. It is the World Health Organization's low-osmolarity ORS formula in a packet: sodium chloride, trisodium citrate dehydrate, potassium chloride, glucose anhydrous. Four ingredients. Manufactured under UNICEF and cGMP regulations.
Each packet makes one full liter and delivers 1,695mg sodium and 779mg potassium -- the highest raw electrolyte density of any product we reviewed. Like NormaLyte PURE, the 13.5g glucose is functionally required for the sodium-glucose co-transport mechanism, not added for taste.
At $0.30 per serving, Trioral is by far the cheapest product in our rankings. It tastes like what it is -- a clinical rehydration solution -- which is to say, not great. There is no magnesium or calcium, and the unflavored profile limits daily drinkability. But for travel, illness recovery, or anyone who needs effective rehydration at the lowest possible cost, nothing else competes.
Standout: WHO-formula ORS at $0.30/serving. The clinical standard at a fraction of the price.
Best By Category
Best Overall: Needed Hydration Support
The only product in our top picks with a perfect clean label, verified batch testing, and a complete electrolyte profile including trace minerals. The monk fruit sweetener and real lemon flavoring set a standard that the rest of the category has not matched.
Best Value: Trioral ($0.30/serving) or LyteShow ($0.50/serving)
Trioral wins on raw cost and electrolyte density if you can tolerate the clinical taste. LyteShow is the better daily-use value pick -- at $0.50 per serving with zero additives, it provides clean electrolytes at a price point that makes daily use sustainable.
Best for Athletes: Transparent Labs Hydrate or Skratch Labs
Two different philosophies, both excellent. Transparent Labs is the better choice for gym training and daily active hydration -- Informed Sport certified, zero sugar, 500mg sodium, plus taurine for cellular hydration. Skratch Labs is the better choice for endurance events -- the intentional sugar content provides fuel alongside hydration, and the real fruit formulation is easy on the stomach during long efforts. Both have strong community credibility in their respective domains.
Best for Fasting and Keto: LyteShow or Redmond Re-Lyte
LyteShow contains zero calories, zero sweeteners (including stevia), and zero sugar -- the cleanest possible option for strict fasting protocols. Re-Lyte is the better option if you want a flavored drink with higher sodium (810mg vs. 125mg), and its zero-sugar stevia-sweetened formula keeps it keto-compatible. Both are Whole30 Approved or paleo-friendly.
Best for Pregnancy: Needed Hydration Support
Formulated specifically for prenatal and lactation needs by a brand that focuses exclusively on maternal nutrition. The balanced 1:1 sodium-to-potassium ratio, 150mg magnesium citrate, trace minerals from seawater, and Clean Label Project certification make it the clear choice. OB-GYN recommended.
Best for POTS and Dysautonomia: NormaLyte PURE
The WHO-formula ORS with clinical evidence for IV-alternative hydration. The 862mg sodium per serving matches the high-sodium protocols that the POTS community has found effective. FSA/HSA eligible, which matters for a product used as medical management rather than occasional supplementation.
Cleanest Formula: LyteShow
Five ingredients. Zero additives, sweeteners, flavors, or colors of any kind. No other product in our 57-product set comes close to this level of ingredient minimalism.
Best Certified for Sport: Transparent Labs Hydrate (Informed Sport) or BPN Electrolytes (NSF Certified for Sport)
Both carry respected third-party banned substance certifications. Transparent Labs holds Informed Sport certification with published COAs. BPN holds NSF Certified for Sport -- one of the most rigorous testing programs available -- and uses TRAACS Albion chelated minerals (bisglycinate forms for magnesium and calcium) that are independently validated for superior bioavailability. BPN at $0.74/serving with 500mg sodium and NSF certification is a strong choice for competitive athletes who need tested-and-verified products.
What We Found: Category-Wide Insights
75% of Products Contain "Natural Flavors"
Forty-three out of 57 products list "natural flavors" as an ingredient. The term is regulated by the FDA but broad enough to encompass hundreds of compounds, including processing aids and carrier solvents that never appear on the label. LMNT's class action lawsuit -- which alleges that 300-450mg of undisclosed maltodextrin was hidden inside their "natural lemon and lime flavors" -- illustrates why this matters. The maltodextrin exceeded the combined weight of the potassium and magnesium in each serving, and it took an independent investigation to uncover it.
Only 8 products earned a perfect clean label by avoiding natural flavors, artificial ingredients, and fillers entirely: Needed, LyteShow, NormaLyte PURE, Skratch Labs, NOOMA, Trioral, Hi-Lyte, and Just Ingredients (though Just Ingredients has separate contamination concerns).
Sodium Varies 20x Across the Category
The lowest-sodium product in our set contains 55mg per serving (Ultima Replenisher). The highest contains 1,000mg (LMNT). That is an 18:1 ratio within a category where every product claims to "hydrate."
For context: you lose 400-1,200mg of sodium per hour of moderate exercise. A product with 55mg of sodium is replacing roughly 5-14% of what you lost. Products below 200mg sodium are, functionally, flavored water with a dusting of minerals. Meaningful hydration support requires at minimum 300mg sodium per serving, and active use or heavy sweaters benefit from 500mg or more.
Cheap Magnesium Is Everywhere
Magnesium oxide -- the cheapest form, with 4-15% bioavailability -- shows up in products from Nuun, Gatorlyte, BodyArmor, and Tailwind. For comparison, magnesium citrate absorbs at roughly 25-30%, magnesium malate and glycinate at 30-40%, and chelated TRAACS forms at 40%+. When a product lists 60mg of magnesium oxide, your body may absorb as little as 2-9mg. The mineral form matters as much as the dose.
Confirmed Contamination in Three Products
Independent laboratory testing has identified contamination in products that consumers trust:
- **LMNT Raw Unflavored:** 27 ppb lead detected by Lead Safe Mama (November 2024). LMNT claims every lot is third-party tested for heavy metals, creating a notable discrepancy between their quality assurance claims and independent findings.
- **Just Ingredients Electrolyte Mix:** The highest lead level found in any electrolyte powder tested by Lead Safe Mama, plus arsenic. Every Just Ingredients product tested to date has come back positive for notable levels of heavy metals. The brand publishes its own COAs showing safe levels -- the discrepancy between self-reported and independent results is concerning.
- **PaleoValley Essential Electrolytes:** 55 ppm total fluorine (PFAS indicator) detected in Mamavation/EHN.org EPA-certified laboratory testing. PFAS ("forever chemicals") have been linked to cancer, birth defects, and lower vaccine effectiveness.
Two MLM Brands, Both Overpriced and Underdosed
Isagenix AMPED Hydrate ($1.88/serving) delivers only 110mg sodium and 100mg potassium through a proprietary "Superfruit Electrolyte Blend" that obscures individual ingredient amounts. Arbonne PhytoSport ($1.75/serving) is better formulated with six electrolytes and BSCG drug-free certification, but the MLM distribution model inflates the price well beyond comparable products from direct-to-consumer brands.
One Product Contains Zero Electrolytes
Zaca Recovery Chewable is marketed as a "hydration + recovery" product but contains exactly 0mg of sodium, potassium, magnesium, and calcium. Its ingredients -- Japanese Raisin extract, glutamine, prickly pear, and glutathione -- are liver-support and recovery compounds, not electrolytes. At $3.50 per serving, it is the most expensive product per serving in our entire set, for a product that does not contain the thing it implies it provides.
Products to Avoid
Zaca Recovery Chewable -- 0.5/10
Zero electrolytes. Zero sodium, zero potassium, zero magnesium, zero calcium. Marketed as "hydration" but contains exclusively liver-support compounds (DHM, glutamine, prickly pear, glutathione). At $3.50 per serving, you are paying premium prices for a recovery supplement that has been filed, inexplicably, in the electrolyte category. If you want liver support after drinking, Zaca may have value. If you want electrolytes, this product does not contain any.
MYOXCIENCE Electrolyte Stix -- 1.7/10
From Thomas DeLauer (YouTube influencer, 8M+ subscribers), MYOXCIENCE refuses to disclose individual electrolyte amounts on the label. The product contains Real Salt, potassium, magnesium, and calcium, but how much of each? Unknown. The 2.6g of Creapure creatine per serving is a useful addition, but hiding electrolyte doses behind vague labeling is a fundamental transparency failure, especially at $1.33 per serving from an influencer-owned brand.
Pedialyte Electrolyte Powder -- 2.7/10
The trusted household name earns one of the lowest scores in our analysis. Pedialyte contains two artificial sweeteners (sucralose and acesulfame potassium), artificial colors (Red 40, Blue 1, Yellow 6 depending on flavor), corn maltodextrin filler, and zero magnesium. Manufactured by Abbott Laboratories to pharmaceutical-grade safety standards, but the formulation reads like it was designed in 1985 and never updated. For a product frequently given to children, the artificial color load is particularly difficult to justify.
Propel Electrolyte Water Powder -- 2.5/10
PepsiCo's Propel delivers token electrolyte amounts: 160mg sodium and 40mg potassium per serving, with zero magnesium, zero calcium, and zero chloride. That is less sodium than you would get from a pinch of table salt. Two artificial sweeteners (sucralose and acesulfame potassium) handle the taste. What you get for $0.34/serving is essentially artificially sweetened, lightly salted, vitamin-enhanced water. It is cheap because there is almost nothing in it.
Liquid I.V. Hydration Multiplier -- Notable Mention
The best-selling electrolyte product in America (Unilever-acquired for $1B) deserves scrutiny proportional to its market dominance. Each 16g stick pack contains 11g of sugar -- the product is approximately 69% sugar by weight. There is no magnesium and no calcium. It provides sodium (500mg) and potassium (370mg) through the same Cellular Transport Technology (sugar-dependent co-transport) used in clinical ORS solutions, but clinical ORS products like Trioral deliver the same science at $0.30/serving instead of $1.50. The Liquid I.V. sugar-free variant addresses the sugar issue but introduces its own formulation tradeoffs.
How to Choose: Buying Guide
Start With Sodium
Sodium is the primary electrolyte lost through sweat and the main driver of fluid retention. A product with less than 200mg sodium per serving is not providing meaningful hydration support. For general daily use, target 300mg minimum. For active use, heavy sweating, or hot climates, 500mg or more is appropriate. Medical conditions like POTS may require 800mg+ per serving under physician guidance.
Check the Mineral Forms
Not all minerals are created equal. The form determines how much your body actually absorbs:
- **Best absorption:** Magnesium glycinate, magnesium malate, magnesium citrate, TRAACS chelated minerals (bisglycinate forms), Aquamin marine-source minerals
- **Good absorption:** Potassium citrate, calcium citrate, sodium citrate
- **Moderate absorption:** Magnesium carbonate, calcium lactate, potassium chloride
- **Poor absorption:** Magnesium oxide (4-15% bioavailability), calcium carbonate
If the label says "magnesium" without specifying the form, assume it is oxide -- brands that use better forms always specify because it costs more and they want credit for it.
Avoid These Ingredients
- **"Natural flavors"** without further specification -- can hide dozens of undisclosed compounds
- **Artificial sweeteners** (sucralose, acesulfame potassium, aspartame) -- increasingly linked to gut microbiome disruption in emerging research
- **Maltodextrin** as a primary ingredient (as a minor processing aid, less concerning) -- high glycemic index filler that spikes blood sugar
- **Proprietary blends** that hide individual electrolyte amounts -- you cannot evaluate what you cannot see
- **Artificial colors** (Red 40, Blue 1, Yellow 6) -- serve zero functional purpose in an electrolyte product
Match the Product to Your Use Case
Daily hydration maintenance: LyteShow, Needed, or Redmond Re-Lyte. Moderate sodium, clean ingredients, sustainable cost for daily use.
Athletic performance and training: Transparent Labs Hydrate or BPN Electrolytes. Higher sodium, third-party sport certifications, zero sugar for flexibility around fueling strategy.
Endurance events (90+ minutes): Skratch Labs or Tailwind. Intentional sugar content provides fuel alongside electrolytes -- this is a feature, not a bug, during prolonged activity.
Medical rehydration (illness, POTS, severe dehydration): NormaLyte PURE or Trioral. WHO-formula ORS solutions designed for clinical-grade rehydration. High sodium, glucose-dependent absorption mechanism.
Fasting or strict keto: LyteShow (zero sweetener, zero calories) or Re-Lyte (stevia-sweetened, zero sugar, high sodium for fasting electrolyte needs).
Frequently Asked Questions
How many electrolytes do I actually need per day?
There is no single answer because it depends on activity level, climate, diet, and individual physiology. The Adequate Intake for sodium is 1,500mg/day for most adults, potassium is 2,600-3,400mg/day, and magnesium is 310-420mg/day. Most people get a significant portion from food. One to two servings of a quality electrolyte supplement fills the gap, particularly if you exercise, fast, eat low-carb, or live in a hot climate.
Is LMNT worth the price despite the maltodextrin controversy?
LMNT delivers a strong electrolyte profile (1,000mg sodium, 200mg magnesium malate, 200mg potassium) and the flavored varieties taste good. The maltodextrin found hidden in the "natural flavors" (300-450mg per serving) and the resulting class action lawsuit are legitimate concerns about ingredient transparency, not about safety. If undisclosed ingredients bother you -- and they should -- alternatives like Re-Lyte (810mg sodium, $0.77/serving) or Transparent Labs (500mg sodium, $0.75/serving) deliver comparable profiles at lower prices with better transparency track records.
Are electrolyte powders better than sports drinks like Gatorade?
For electrolyte content, generally yes. Standard Gatorade provides approximately 160mg sodium per 12oz serving with 21g of sugar and artificial colors. Most quality electrolyte powders deliver 2-6x more sodium with less sugar and cleaner ingredients. The main advantage of traditional sports drinks is taste familiarity and availability. If you are already buying electrolyte powders, you have moved past the convenience argument.
Do I need electrolytes if I am not an athlete?
Yes, though your needs are lower. Electrolytes regulate fluid balance, nerve signaling, and muscle function regardless of activity level. People who benefit most from supplementation beyond athletes: those who eat low-carb or keto (lower insulin reduces sodium retention), those who fast regularly, coffee and alcohol drinkers (both are diuretics), people in hot climates, and anyone taking medications that affect electrolyte balance.
What about coconut water as a natural electrolyte source?
Coconut water provides roughly 600mg potassium and 250mg sodium per 16oz serving, making it a decent potassium source but an inadequate sodium source. It also contains 11-12g of natural sugar per serving. Several products in our review (NOOMA, Cure, Transparent Labs) use coconut water powder as an ingredient, combining its natural potassium with added sodium and magnesium to create a more complete profile. Plain coconut water is fine for mild daily hydration but does not replace a formulated electrolyte product for active use or specific health needs.
Should I worry about heavy metals in electrolyte powders?
The electrolyte category has received far less independent testing scrutiny than protein powders, where Consumer Reports and Clean Label Project have found widespread contamination. The data that does exist -- from Lead Safe Mama and Mamavation -- has identified confirmed issues in specific products (LMNT Raw, Just Ingredients, PaleoValley). Products with third-party certifications like NSF Certified for Sport or Informed Sport include heavy metals testing in their protocols. If contamination is a primary concern, prioritize certified products or brands that publish COAs showing independent test results.
