Analysis

The glycinate amino acid complex is a favorable disclosed form for a small potassium serving. At 99 mg, it contributes little toward typical daily intake.

Its focused composition is easy to assess and may complement a potassium-rich diet. The single ingredient does not address broader cardiovascular pathways.

A tablet format supports consistent dosing without the measuring demands of powder. The label would be clearer if it separated complex weight from elemental potassium yield.

Who is it for
  • Adults who prefer chelated mineral forms
  • People seeking a controlled low-dose tablet
Best for
  • Low-dose potassium support
  • Simple daily supplementation

Pros

  • Favorable glycinate complex
  • Clearly listed active amount
  • Convenient tablet format

Cons

  • Low potassium potency
  • Elemental yield is not separately stated
  • No broader heart-health ingredients

Warnings

  • The 99 mg potassium serving may be unsuitable with impaired kidney function because potassium can accumulate.
  • ACE inhibitors, ARBs, and potassium-sparing diuretics can increase the risk of excessive blood potassium.
  • Taking potassium without enough fluid or food may cause stomach irritation in sensitive users.

Nutrient quality

79 High impact

A potassium glycinate amino acid complex provides a high-quality chelated source. The elemental amount is too small for substantial potassium support, while the low amount avoids obvious excess in healthy adults.

Ingredient transparency

78 High impact

The chelated source and amount are clear, though compound weight and elemental yield are not separated. Serving totals are apparent, but full directions and inactive ingredients are not supplied.

Customer satisfaction

63 Moderate impact

The supplied average rating is favorable. The moderate rating base offers some confidence but is not extensive, while complaint and firsthand experience details are unavailable.

Value for money

86 Highest impact

Formula quality provides partial support for the asking position. The serving value is reasonably competitive within the category.

Potassium supports sodium balance and normal blood-pressure physiology, but the 99 mg amount is very small. The focused formula is relevant to one cardiovascular pathway without claiming broader mechanisms.

A glycinate amino acid complex is a favorable disclosed form. The low amount limits practical contribution despite good transparency and a streamlined label.

A+ Active Ingredient Quality & BioavailabilityD Dose, Safety & Label TransparencyD+ Value

Potassium glycinate amino acid complex is a high-quality chelated form, but the 99 mg serving is low. The amount is easy to identify, while the compound weight and elemental yield are not separately shown. Very low serving cost provides fair value for users who specifically want a small supplemental dose.

87 Performance

Potassium Bicarbonate 1.3 g

Nutricost
<p>A clearly labeled 494 mg of potassium bicarbonate provides a meaningful, alkalizing alternative to the original's potassium contribution. The simple powder improves dose clarity, but impaired kidney function or potassium-retaining medicines can make the amount unsafe without guidance.</p>
83 Performance

Potassium Citrate

NOW
<p>Potassium citrate supplies a meaningful 448 mg amount in a well-absorbed, alkalizing form. Its focused label gives stronger form and dose clarity than many mixed products, while kidney impairment and potassium-retaining medicines can raise blood potassium too far.</p>
80 Performance

Albion Complexed Potassium 99 mg

Swanson Ultra
<p>A named Albion amino acid complex provides a clearly identified potassium form for users who prefer a low-dose capsule. The 99 mg amount is far smaller than the higher-dose powder options, so its advantage is form clarity rather than substantial electrolyte delivery.</p>
85 Budget

Potassium Chloride 365 mg

Nutricost
<p>A clearly quantified 365 mg of potassium chloride makes this a focused, low-cost substitute for the original's potassium component. Chloride supports electrolyte replacement but lacks the buffering role of citrate or bicarbonate, and kidney impairment or potassium-retaining medicines can make supplementation unsafe.</p>
81 Budget

Potassium Chloride Powder

NOW
<p>The simple powder provides 365 mg of potassium as chloride with very low recurring cost. It is easier to assess than a broad blend but lacks citrate's buffering role, while kidney impairment or potassium-retaining medicines remain important cautions.</p>
80 Budget

Potassium 99 mg

Thompson
<p>A 99 mg potassium amino acid complex offers a low-cost, deliberately modest alternative to the original. The amount contributes little beside daily dietary needs, so it fits limited supplementation rather than substantial electrolyte replacement.</p>
81 Value

Potassium (Citrate)

Pure Encapsulations
<p>A simple capsule supplies 200 mg of potassium citrate, providing an absorbable and alkalizing form at a moderate amount. It offers a practical middle ground between low-dose tablets and concentrated powders, with the same kidney and medication cautions that apply to added potassium.</p>
80 Value

Potassium Gluconate Pure Powder

NOW
<p>A focused powder supplies 175 mg of potassium gluconate with excellent recurring value. The amount is more useful than a basic 99 mg tablet but remains a limited contribution beside dietary needs, and potassium retention from kidney disease or medicines still matters.</p>
78 Value

Potassium 99 mg

Country Life
<p>Citrate and an amino acid chelate provide useful form quality in a streamlined supplement. Repeated 99 mg entries make the total potassium amount ambiguous, but the low recurring cost supports cautious, modest use.</p>
