The label says 595mg, but that's the weight of the **Potassium Gluconate** compound — your actual potassium per tablet is 99mg. That's the FDA's legal ceiling for over-the-counter potassium supplements, so you're getting as much as any single tablet can deliver. But it's still well below the 200–500mg supplemental range studied for blood pressure and muscle function support.
Potassium works by helping your body excrete excess sodium, which is why higher intake is linked to healthier blood pressure. At 99mg per tablet, you'd need two to three tablets to reach the minimum studied supplemental dose — though most of your potassium should come from food sources like potatoes, bananas, and leafy greens.
If you're specifically supplementing for heart or muscle support, know that this covers only about 3% of the 3,400mg daily adequate intake. It's a top-up, not a replacement for dietary potassium.
