📰Read the full Electrolyte Salts evidence review on GMJ News →Complete clinical article, references and updates on news.gmj.ge. This page is the structured safety summary.⚠ Patient on ACE inhibitor/ARB + K-containing electrolytes — hyperkalemia [1]
⚠ Premium products = same minerals as salt + lite salt for 10–50× price [2]
⚠ Keto flu: supplement Na 3–5 g, K, Mg [2]
⚠ WHO ORS: 6 tsp sugar + 1/2 tsp salt + 1 L water — saves lives [1]
ℹ️ Not obtained from food. Not applicable — this is not obtained from food in meaningful amounts; supplementation is the practical route.

Clinical verdict
WHO ORS = one of history's most important medical interventions. For exercise: Na replacement prevents hyponatremia during >2 hr activity. For keto: supplement Na/K/Mg to prevent 'keto flu.' Premium electrolyte products are mostly overpriced — salt + lite salt + water = same minerals for pennies. Most sedentary people don't need electrolyte supplements [1] [2].
1 How much do I need?
👤 Adults: Specific dosage data under clinical review
👴 Elderly: Specific dosage data under clinical review
🤰 Pregnancy: See guidance
ORS for dehydration. Adequate electrolytes important [1].
👦 Pediatric: See guidance
Pedialyte/ORS for pediatric dehydration: standard of care [1].
🏃 Athletes: Standard dose
⚖️ Obesity: Standard dose
Fat-soluble compounds may require dose adjustment in obesity.
🩺 Renal: Consult specialist
Dose adjustment may be needed in renal impairment.
🌱 Vegan: Standard dose
How to take
💊 With food: Dissolved in water [1].
🚫 Avoid: K supplements with ACE/ARB/K-sparing diuretics without monitoring [1].
2 Which form?
| Form | Bioavailability | Vegan | Cost |
|---|---|---|---|
| ['WHO ORS (oral rehydration salts)', 'gold standard', 'For diarrheal dehydration. Na 75 mEq/L, glucose 75 mmol/L, K 20 mEq/L [1].'] | Standard | Check label | |
| ['Sports electrolyte drinks/powders', 'common', 'Variable formulations. Check Na/K/Mg content [2].'] | Standard | Check label | |
| ['Electrolyte capsules', 'common', 'Salt capsules for endurance athletes [2].'] | Standard | Check label | |
| ['LMNT, Drip Drop, Pedialyte', '', 'Branded products. Variable quality and pricing [2].'] | Standard | Check label |
3 Common questions
Do I need electrolyte supplements? ▼
Only if: (1) exercising intensely >1 hour, (2) diarrhea/vomiting, (3) ketogenic diet, (4) excessive sweating. Most sedentary people eating a normal diet do NOT need electrolyte supplements [2].
Are premium electrolyte products worth it? ▼
A pinch of salt + lite salt (KCl) in water provides the same Na and K as products costing 10–50× more. The minerals are identical. You're paying for branding and flavoring [2].
What is 'keto flu'? ▼
When starting a ketogenic diet, insulin drops → kidneys excrete more sodium → water follows → dehydration + electrolyte depletion. Supplementing Na (3–5 g), K, and Mg prevents most symptoms [2].
4 Clinical evidence
Strong
WHO ORS for diarrheal dehydration: one of the most important medical interventions in history (>1 million lives saved annually) [1]. Sodium replacement during prolonged exercise prevents hyponatremia [2]. HIGH
Moderate
Exercise performance: sodium supplementation during prolonged exercise (>2 hours) maintains plasma volume and performance [2]. Keto adaptation: electrolyte supplementation reduces 'keto flu' symptoms [2]. MODERATE
Insufficient
5 Safety, toxicity & adverse events
Absolute contraindications
✕ Advanced kidney disease or hyperkalemia (for potassium-containing products)
Relative
⚠ Heart failure or hypertension — sodium load
⚠ Concurrent ACE inhibitors/ARBs/potassium-sparing diuretics — hyperkalemia risk with potassium salts
⚠ Adrenal insufficiency
🚩 Red flags
● Renal failure + K supplements — hyperkalemia [1]
● ACE/ARB + K-containing electrolytes — monitor K [1]
● Hyponatremia from excessive water + insufficient Na during marathon — serious [2]
6 Interactions
Drug interactions
ACE inhibitors/ARBs/K-sparing diuretics Major
Mechanism: Additive potassium retention. [1]
Effect: Hyperkalemia → cardiac arrhythmia. [1]
Action: Monitor serum K. Avoid high-dose K supplements without guidance [1].
Lithium Moderate
Mechanism: Sodium intake affects renal lithium handling. [1]
Effect: Variable lithium levels. [1]
Action: Maintain consistent Na intake. Monitor lithium [1].
Supplement synergies
Magnesium glycinate · 200–400 mg Mg
Mg is the most commonly deficient electrolyte — oral salts provide Na/K but often lack Mg [2].
Mg is the most commonly deficient electrolyte — oral salts provide Na/K but often lack Mg [2].
7 Regulatory
WHO: ORS formulation is a WHO Essential Medicine [1].
United States: Electrolyte supplements: dietary supplements/foods [2].
