Study, Trial or Testing Result Summary
Members OnlyHuman studies
This is a flavored powdered heart tonic taken as a 6 gram serving. The label and the store listing give only the product name and serving size. They do not list the individual ingredients or their amounts, so we cannot tell which ingredients are present or whether any are at the doses used in research. Our research found no human studies on blood pressure for the ingredients of this product, and no ingredient findings were available to review. Because of this, there is no study evidence for or against it lowering or controlling blood pressure. No customer reviews were counted and no written reviews could be read, so we know nothing about how users rate it or what effects they report. Until the full ingredient list and doses are known and studies on those ingredients are found, this product cannot be judged on its likely effect on blood pressure. Anyone managing high blood pressure should rely on proven treatments and talk with a doctor before adding a supplement like this one. Animal and cell studies are never counted.

Biohacker Summary
Members Only0 of 10 recommend it
0 of 10 biohackers on our panel recommend it
This product's ingredients are potassium and sodium, both smaller ingredients in this product, so the panel's views are best taken together. Several of the ten use or recommend them as electrolytes in drinks, especially for hydration, workouts and fasting, with one mentioning 500 mg of sodium and another 100 mg of potassium per can, and one suggesting 200 to 400 mg of each daily for women in the luteal phase. Potassium gets mostly positive comments for heart, muscle and blood pressure support, and a few say most people do not get enough, with one advising food sources like bananas and potatoes over supplements. Sodium draws more caution: three panelists warn that most people get too much, with one suggesting about 1,500 mg a day and no more than 2,300 mg, one noting that salt-sensitive people can see blood pressure rise, and one noting that meds flush out potassium. Nobody said they had stopped taking either one.
