Harvard Health: The Importance of Potassium
Most Americans get barely half the potassium they need — and the imbalance between too much sodium and too little potassium is a major driver of high blood pressure. Here's what Harvard Health lays out about why this mineral matters.
Why Potassium Matters
Potassium is essential to every cell in the body. It regulates the heartbeat, keeps muscles and nerves firing correctly, and supports protein synthesis and carbohydrate metabolism. The recommended adequate intake is 4,700 mg per day — yet the typical American diet delivers about half that, while supplying roughly twice as much sodium as potassium. For perspective, early human diets ran the opposite way: about 16 times more potassium than sodium. That flip, driven by salt hidden in processed and prepared foods, is thought to be a major contributor to high blood pressure, which affects one in three American adults.
What the Evidence Shows
The DASH trial (Dietary Approaches to Stop Hypertension) found that potassium-rich eating measurably lowered blood pressure — a diet rich in fruits and vegetables (about 4,100 mg potassium/day) outperformed a standard low-potassium diet, and the effect was largest in people who already had high blood pressure. Potassium's blood-pressure benefit also extends to stroke risk: one study following more than 43,000 men for eight years found those with the highest potassium intake (~4,300 mg/day) were 38% less likely to have a stroke than those taking in far less.
Why This Matters for REV
This is the core reason REV Electrolyte Gum is built around potassium and magnesium rather than sodium. Most people are already over their sodium target and well under their potassium one — so the electrolyte worth adding through the day is the one you're actually short on. REV Electrolyte Gum delivers potassium conveniently, without sugar and without a drink, as one easy way to chip away at that 4,700 mg daily target alongside potassium-rich foods like bananas, potatoes, and leafy greens.
A Few Caveats
Harvard's guidance is clear on two points worth repeating: get potassium primarily from food, and never take potassium supplements without a doctor's prescription — too much potassium in the blood is dangerous, especially for people with kidney issues or those on certain medications. REV Electrolyte Gum is a modest, food-level source meant to complement a balanced diet, not a high-dose supplement or a treatment for any condition.
