Plain water never seems to fix it — I suspect I'm low in a key electrolyte
Potassium Deficiency
Centuries of traditional use· Human evidence not yet assessed (Evidence grade not assigned · Traditional use long-standing)Long-standing traditional stapleLow potassium drives cramps and fatigue
- Why this matches
- Potassium is a key electrolyte lost through sweat and heat; when it runs low you can feel crampy, weak and wiped out after exertion.
- Why try it
- Naming this possible gap complements replacing potassium through food or supplements, so you address the cause of the cramps rather than just the symptom.
- Dose or use
- Educational guide — check the signs and, if they fit, lean on potassium-rich foods; discuss supplements with a practitioner, especially with kidney issues.
- Time to results
- Cramping and fatigue from a shortfall often improve within days to a couple of weeks.
- Key study
- Educational deficiency overview; not a treatment claim and not tied to a specific clinical trial here.
- Caution

Sodium Deficiency
Centuries of traditional use· Human evidence not yet assessed (Evidence grade not assigned · Traditional use long-standing)Long-standing traditional stapleSodium is the main electrolyte lost in sweat
- Why this matches
- If you feel drained, headachy or crampy after sweating, low sodium may be part of the picture — it is the electrolyte you lose most through sweat.
- Why try it
- Understanding a possible sodium gap helps explain why plain water alone can leave you feeling off, and points you toward replacing salts, not just fluids.
- Dose or use
- Educational guide — review the signs and, if they fit, focus on electrolyte-containing foods and fluids; ask a practitioner before adding salt if you have blood pressure concerns.
- Time to results
- Symptoms from a genuine shortfall often ease within days of restoring sodium.
- Key study
- Educational deficiency overview; not a treatment claim and not tied to a specific clinical trial here.
- Caution

Centuries of traditional use· Human evidence not yet assessed (Evidence grade not assigned · Traditional use long-standing)Long-standing traditional stapleLow magnesium can trigger cramps and spasms
- Why this matches
- Magnesium is lost through sweat, and a shortfall is a common driver of the muscle cramps and fatigue that show up after exercise.
- Why try it
- Seeing magnesium as a possible underlying gap pairs naturally with the magnesium supplement option — you address the deficiency, not just the symptom.
- Dose or use
- Educational guide — review the signs and, if they fit, prioritize magnesium-rich foods or a supplement discussed with your practitioner.
- Time to results
- Cramp relief from correcting a shortfall often takes a few weeks.
- Key study
- Educational deficiency overview; not a treatment claim and not tied to a specific clinical trial here.
- Caution
- High-dose magnesium can cause loose stools; get advice if you have kidney disease.
Chloride Deficiency
Centuries of traditional use· Human evidence not yet assessed (Evidence grade not assigned · Traditional use long-standing)Long-standing traditional stapleChloride helps hold everyday fluid balance
- Why this matches
- For steady day-to-day balance, chloride matters too — it works alongside sodium to maintain fluid balance, and a shortfall can bring fatigue and dehydration.
- Why try it
- Chloride is quietly lost with sodium in sweat; recognizing it rounds out your electrolyte picture beyond just sodium and potassium.
- Dose or use
- Educational guide — for most people normal salted food covers chloride; review the signs if you suspect a gap.
- Time to results
- Symptoms from a genuine shortfall typically ease within days of restoring electrolytes.
- Key study
- Educational deficiency overview; not a treatment claim and not tied to a specific clinical trial here.
- Caution
- Persistent low chloride can signal an underlying issue — see a practitioner if it continues.

Sodium Deficiency
Centuries of traditional use· Human evidence not yet assessed (Evidence grade not assigned · Traditional use long-standing)Long-standing traditional stapleSodium is the main electrolyte lost in sweat
- Why this matches
- If you feel drained, headachy or crampy after sweating, low sodium may be part of the picture — it is the electrolyte you lose most through sweat.
- Why try it
- Understanding a possible sodium gap helps explain why plain water alone can leave you feeling off, and points you toward replacing salts, not just fluids.
- Dose or use
- Educational guide — review the signs and, if they fit, focus on electrolyte-containing foods and fluids; ask a practitioner before adding salt if you have blood pressure concerns.
- Time to results
- Symptoms from a genuine shortfall often ease within days of restoring sodium.
- Key study
- Educational deficiency overview; not a treatment claim and not tied to a specific clinical trial here.
- Caution
- Very low sodium (hyponatremia) can be serious — seek medical advice for severe confusion, nausea or weakness.
Magnesium Deficiency
Centuries of traditional use· Human evidence not yet assessed (Evidence grade not assigned · Traditional use long-standing)Long-standing traditional stapleLow magnesium can trigger cramps and spasms
- Why this matches
- Magnesium is lost through sweat, and a shortfall is a common driver of the muscle cramps and fatigue that show up after exercise.
- Why try it
- Seeing magnesium as a possible underlying gap pairs naturally with the magnesium supplement option — you address the deficiency, not just the symptom.
- Dose or use
- Educational guide — review the signs and, if they fit, prioritize magnesium-rich foods or a supplement discussed with your practitioner.
- Time to results
- Cramp relief from correcting a shortfall often takes a few weeks.
- Key study
- Educational deficiency overview; not a treatment claim and not tied to a specific clinical trial here.
- Caution
- High-dose magnesium can cause loose stools; get advice if you have kidney disease.
Chloride Deficiency
Centuries of traditional use· Human evidence not yet assessed (Evidence grade not assigned · Traditional use long-standing)Long-standing traditional stapleChloride helps hold everyday fluid balance
- Why this matches
- For steady day-to-day balance, chloride matters too — it works alongside sodium to maintain fluid balance, and a shortfall can bring fatigue and dehydration.
- Why try it
- Chloride is quietly lost with sodium in sweat; recognizing it rounds out your electrolyte picture beyond just sodium and potassium.
- Dose or use
- Educational guide — for most people normal salted food covers chloride; review the signs if you suspect a gap.
- Time to results
- Symptoms from a genuine shortfall typically ease within days of restoring electrolytes.
- Key study
- Educational deficiency overview; not a treatment claim and not tied to a specific clinical trial here.
- Caution
- Persistent low chloride can signal an underlying issue — see a practitioner if it continues.
