What it is
An unflavored mineral stick you stir into a litre of filtered water. It is built around potassium delivered as two salts -- potassium citrate and potassium bicarbonate -- alongside MSM and taurine. One 2.3 g packet per litre gives 451 mg of potassium (10% of the Daily Value), 1000 mg of MSM, and 100 mg of taurine. There are no other ingredients at all: no added sugar, no flavoring, no soy, dairy, or yeast. It comes as single-serve sticks and as a tub you scoop from.
Why the evidence supports it
Potassium is one of the few nutrients the Dietary Guidelines single out as a public-health shortfall -- most adults sit well under the target, and it is the mineral that sets the electrical charge across every cell membrane. Worth understanding clearly: the citrate and the bicarbonate are both carriers for potassium, so it arrives by two routes rather than being one item in a list of five. The 451 mg is the total elemental potassium across both salts, and the label does not separately quantify citrate or bicarbonate, so no amount-based claim can be made about either one on its own.
What it supports
- Supports normal daily hydration
- Contributes meaningful potassium toward a commonly under-met intake
- Supports normal fluid and electrolyte balance
- Supports the normal membrane potential cells depend on
Which function it supports
Ties to the cell's Exchange function -- potassium is the ion that sets the charge across the cell membrane, which is what lets nutrients, signals, and waste move in and out.

- Potassiumsolid evidence
via Potassium · 83 studies, 19 in people
What people often notice when this marker sits outside the usual range
Higher: Serum potassium is a SAFETY marker, tightly regulated -- the body defends the blood level even when dietary intake is low, so a normal serum value does not confirm good dietary intake.
Lower: A low serum potassium (hypokalaemia) can cause muscle cramps, weakness, fatigue, constipation and palpitations -- also a medical finding to address with a clinician.
- Sodium (and the Na:K Ratio)solid evidence
via Potassium · 83 studies, 19 in people
What people often notice when this marker sits outside the usual range
Higher: Serum sodium is tightly regulated and mostly reflects hydration, so it is not a gauge of dietary sodium intake.
Lower: A low serum sodium (hyponatraemia) can cause headache, nausea, confusion and, when severe, seizures -- usually from overhydration or illness, and a medical finding for a clinician.

What people often notice when this marker sits outside the usual range
Higher: Because muscle-meat and refined foods are low in magnesium, shortfall is common on modern diets.
Lower: A high serum magnesium is rare and almost always tied to impaired kidney function (weakness, low blood pressure) -- a medical finding, since magnesium is renally cleared.

No product works in isolation
Every cell function above -- Sense, Exchange, Transform, Build, Maintain, Adapt -- needs the same broad base of optimal micronutrient levels running underneath it, all the time. Hydro-Life is not a stand-alone fix; it is one piece that plugs into that larger system. The foundation comes first, and this supports it.

Foundational, or targeted?
Not everything in the shop is meant to be taken forever. Some products here are foundational -- a daily nutrient base built for long-term, ongoing use. Others are targeted -- shorter-term support for a specific season, not a lifelong habit. If you are not sure which one this is, that is a fair question to ask us before you buy.

Search the full studies libraryHow to use it
One stick per litre of filtered, distilled, or deionized water, sipped through the day. The label suggests 1.5-2 litres daily, which works out to roughly 677-902 mg of added potassium a day. That is a real amount of potassium, and the kidneys are what clear it -- so reduced kidney function and blood-pressure medication are the two things that change the arithmetic. ACE inhibitors, ARBs, and potassium-sparing diuretics all raise potassium on their own, so know your own starting point before adding to it.

Hydro-Life is an unflavoured mineral stick you stir into a litre of filtered water, built around potassium delivered as two salts (citrate and bicarbonate) with MSM and taurine. Potassium is one of the nutrients most people genuinely run short on, and this is aimed at the water you already drink.
FAQ
What does Hydro-Life support?
It supports normal hydration and electrolyte balance, and supplies potassium, which supports normal muscle and nerve function and normal blood pressure as part of a balanced diet.
How do I take it?
Stir one stick into about a litre of filtered water and drink through the day, per the label. It is unflavoured, so it does not change what your water tastes like much.
What makes it different?
Most electrolyte products lead with sodium. This one is potassium-forward, which is the mineral the typical diet actually runs low on. ⚠️ If your kidney function is reduced, potassium needs a doctor's input before you add it.
