Potassium Hydration, Not Salt: The Water We Chose

20¢ a serving$39.99 · 200 servings

Why this form

Potassium, taurine, MSM. Nothing else.

Hydro-Life is a powder you stir into a litre of water: one stick, or a scoop from the bulk pouch. Per litre it holds 451 mg of potassium as citrate and bicarbonate, 1,000 mg of MSM and 100 mg of taurine. No sodium, no sugar, no flavoring, no soy, dairy, yeast or gluten. Spring water taste.

The potassium arrives as the alkaline salts. In 8 healthy men on a 32 gram a day salt diet, adding potassium bicarbonate lowered adrenal glucocorticoid output; cutting the salt alone did not.¹¹

Hydro-Life Supplement Facts panel: potassium 451 mg, MSM 1,000 mg, taurine 100 mg per stick

The pair

Potassium and magnesium. The blood test misses both.

A serum potassium can read normal while the cell runs short.² A serum magnesium does the same.⁴ Mag-ATP is 300 mg of magnesium in three capsules, as bisglycinate and taurate.

Where the water goes

Hydration is not water. It is where the water goes.

Every cell keeps potassium inside and sodium outside, and water follows the minerals. Taurine is the molecule the cell uses to set its own volume.³

Skeletal muscle rapidly took up about 98 percent of a potassium dose in resting rats.¹ A 2026 review describes intracellular potassium deficiency despite a normal serum level, linked to mitochondrial dysfunction, oxidative stress and impaired insulin sensitivity.²

And almost nobody is at the target. Across 1.6 million people in 52 countries the mean intake is 2.25 grams a day.⁵ In the US food survey for 2017 to 2018, most Americans took in under 2,600 milligrams on the reporting day, and only about a quarter of men exceeded the 3,400 milligram Adequate Intake.⁶ In young South African adults, over 90 percent fell below the recommended 3,510 milligrams.⁷

The slippery lining

Salt stiffens the vessel wall. Potassium softens it.

In endothelial cells, potassium softened the cell cortex and increased nitric oxide release while sodium stiffened it.⁸ The glycocalyx, the gel coat inside every artery, shields the endothelial cells from excess salt absorption,⁹ and in a microfluidic study its breakdown was highest at 160 mEq of sodium per litre, with its thickness reduced.¹⁰

In a crossover trial of 94 adults, a low-sodium, high-potassium diet improved depression, tension and vigor scores more than a moderate DASH-type diet.¹² Hospitals know the mineral matters: in 2,402 bypass patients, a potassium under 3.5 mmol/L before surgery went with 2.2 times the odds of an arrhythmia.¹³

What the trials found

Three ingredients, one line each.

Potassium. Across 33 randomized trials, more potassium went with lower blood pressure,¹⁴ and across 32 the drop grew with the dose.¹⁵

Taurine. Across 20 randomized trials and 808 people, it lowered systolic pressure by about 4 mmHg and heart rate by 3.6 beats a minute.¹⁸

MSM. At up to four grams a day it went with lower inflammation and oxidative-stress markers in human and animal studies,¹⁹ and in 88 adults with mild knee pain, 12 weeks gave a small but significant gain in knee quality of life over placebo.²⁰

Read the full story

Hydration is where the water goes, not how much you drink. Potassium is the mineral the cell holds inside and water follows it; sodium is kept outside. Most US adults sit well under the potassium target, and about 98 percent of the body's potassium is inside cells, so a normal blood test can miss a shortfall. The product on this page is a potassium citrate and bicarbonate powder with taurine and MSM: no sodium, no sugar, no flavoring.

Potassium hydration: the common questions

What does hydration actually mean?

Hydration is where the water goes, not how much you drink. Every cell keeps potassium inside and sodium outside, water follows the minerals, and taurine is the osmolyte the cell uses to set its own volume.

What is in Hydro-Life?

Per litre of water: 451 milligrams of potassium delivered as potassium citrate and potassium bicarbonate, 1,000 milligrams of MSM (methylsulfonylmethane) and 100 milligrams of taurine. No other ingredients: no sodium, no sugar, no flavoring, no soy, dairy, yeast or fillers. Label as printed on the stick pack. The bulk pouch and jar are the same concentration, counted as 200 half-litre servings.

Why potassium instead of sodium for hydration?

Potassium is the mineral cells hold inside, and water follows it; sodium is kept outside. In endothelial cells potassium softened the cell cortex and increased nitric oxide release while sodium stiffened it, and in a microfluidic study glycocalyx degradation rose with sodium. The glycocalyx is the gel coat inside every artery. This is why the label on this page leads with potassium and carries no sodium.

Can a blood test tell me if I am low in potassium?

Not reliably. In resting rats, skeletal muscle rapidly absorbed about 98 percent of a potassium dose, so a blood test reads only the small fraction outside. A 2026 review describes intracellular potassium deficiency despite a normal serum level, linked to mitochondrial dysfunction, oxidative stress and impaired insulin sensitivity. Serum magnesium has the same limitation.

How much does it cost per day?

The 200-serving bulk pouch was $39.99 on the manufacturer's site on 2026-11-01, about 20 cents a serving, and it comes with a scoop. The bulk jar is $41.99, 32 sticks are $29.99 and the 8-stick travel pack is $12.99. The affiliate link tracks the referral; there is no discount code, and the price you pay is the manufacturer's.
