Three things to remember
- Compare potassium itself, not potassium-salt weight.
- A dietary adequate intake is not an instruction to replace that amount with pills.
- Kidney disease and several medicines can make extra potassium dangerous.
What the evidence supports
Potassium-rich dietary patterns can support blood-pressure control, especially alongside lower sodium intake. Beans, potatoes, fruits, vegetables and dairy can contribute. This does not make every potassium tablet an equivalent substitute for the whole dietary pattern.
A product marketed for hydration, heart health or cramps needs evidence appropriate to that purpose. A nutritional role alone cannot establish that adding potassium treats a particular symptom or replaces clinical care.

Forms and source weight
Potassium chloride, citrate, bicarbonate and gluconate are among supplemental forms. No universally superior nutrition form is established by the reviewed ODS guidance. Some salt substitutes also supply potassium.
Compare the nutrient amount per measured serving. A gram of potassium chloride is not a gram of potassium itself. Keep electrolyte-blend total weight, sodium content and potassium content in separate fields instead of merging them into a single 'mineral strength' number.

US adequate-intake context
The US/NASEM 2019 adequate intakes for adults 19 and older are 3,400 mg/day for men and 2,600 mg/day for women from total intake. They are AIs, not an instruction to obtain that quantity from a supplement.
For example, a hypothetical 100 mg supplement is about 2.9% of 3,400 mg or 3.8% of 2,600 mg. That illustrates the scale difference; it is not a reason to multiply tablets until reaching an AI.

Hypothetical serving and price calculation
A ₹300 bottle has 60 tablets with 100 mg potassium each. The labelled one-tablet serving costs ₹5. A ₹450 powder has 30 servings, each declaring 300 mg potassium, costing ₹15 per serving.
Both have the same price per 100 mg, but their serving amounts, other ingredients and practical use differ. If the powder scoop weight is 5 g, that does not mean 5 g potassium. The nutrient panel, not scoop weight, supplies the figure used for this comparison.
Safety that cannot be reduced to a number
Kidney disease, ACE inhibitors, angiotensin-receptor blockers and potassium-sparing diuretics can raise potassium dangerously. Even typical dietary amounts can require individual management in susceptible people. Excess concentrated supplements or salt substitutes can cause hyperkalaemia.
Other diuretics can lower potassium instead. These differences make medicine-specific assessment essential. A 'low sodium' claim does not establish that a potassium-based salt substitute is suitable for everyone.

Useful comparison fields
For tablets, show potassium per tablet and complete serving. For drink powders, include prepared volume, sodium and potassium separately. For salt substitutes, include the potassium declaration per measured amount and avoid presenting them as unlimited flavouring.
The US sources do not provide a general upper-limit number that can certify a product as safe for every user. Record missing concentration data as missing. A lower price per gram of powder is not meaningful until the actual potassium and other ingredients are known.

Common questions
Can I use potassium pills to reach the dietary adequate intake?
The dietary reference is not a pill regimen. Concentrated potassium can be hazardous, especially with kidney disease or interacting medicines.
Is a low-sodium salt automatically suitable for everyone?
No. Some replace sodium with potassium, which can be unsuitable in particular medical and medication contexts.
Take the knowledge with you.
Compare the same form, active amount and intended use before comparing price. India and International listings have separate filters; some categories may have no listings in one market. Listings do not establish local stock or a need for a supplement. Shopping disclosures appear on product pages.
