Why I Made Kalyx.
I had high blood pressure. I was training hard, CrossFit and lifting weights, but my numbers were still too high. I tried meds but I couldn’t handle the side effects and had to stop.
Later I got sick, and developed AFib.
That’s when I started learning about potassium. Once I started getting more of it, my blood pressure came down to normal, and today I rarely get AFib. I drink potassium every single day.
When I went looking for an electrolyte mix to make that easy, almost everything I found was mostly salt with a little potassium on the side. So I made the one I wanted: 750 mg potassium, 500 mg sodium, 150 mg magnesium, and nothing extra.

Smooth, light, clean finish.
Most electrolyte mixes taste like a mouthful of seawater, then cover it with stevia. Kalyx uses a more balanced mineral profile, so it drinks light and finishes clean.
- 01Light, not overpowering
A smoother taste without the salt-bomb intensity.
- 02No nasty aftertaste
No stevia or sweeteners of any kind. Unflavored is clean and mineral; Citrus is bright lemon-lime from natural flavor.
- 03Delicious and easy to drink daily
Light enough for the morning, a workout, the sauna or a fasting day.
Why Potassium Leads.
The FDA Daily Value for potassium. Most Americans fall short.
3 in 4 U.S. adults don’t get the recommended amount of potassium (USDA, NHANES 2017–2018). You lose some every time you sweat, yet most electrolyte mixes are built around salt and replace only a little of it.
In short, it’s about balance. Most of us get plenty of sodium but not nearly enough potassium. Research links a high sodium-to-potassium ratio, meaning a lot of salt and too little potassium, to higher blood pressure and heart risk.
Your nerves and muscles depend on potassium to work properly. Fatigue is a common sign of running low, so people who are short often feel better and more energized once they get enough.*
Most mixes treat potassium as an afterthought. We don’t. And low stores aren’t fixed overnight: depleted potassium can take weeks to restore (NIH StatPearls). That’s why it belongs in your daily routine.
FDA Daily Values: potassium 4,700 mg, sodium 2,300 mg, magnesium 420 mg.
- 01Your muscles run on it
Potassium is needed for normal muscle function and contraction, including during hard training.*
- 02Low levels matter
Low potassium (hypokalemia) is linked to muscle weakness and cramps, and can contribute to heart rhythm problems (arrhythmia).
- 03So we lead with it
750 mg per stick, 16% of the Daily Value.
Why Magnesium Matters
36% of the Daily Value in every stick.
The RDA for adults is 420 mg for men and 320 mg for women, and national survey data show many Americans fall short. That's why every stick has 150 mg.
- 01Muscle, nerve and energy
Magnesium supports normal muscle and nerve function and energy metabolism, and it is lost in sweat.*
- 02Low levels matter
Low magnesium is linked to muscle cramps and can contribute to heart rhythm issues.
- 03A meaningful dose
150 mg per stick — enough to matter without overloading the formula.

Why does Kalyx cost $44.95?
We spend more on what goes into each stick. Kalyx is built around meaningful doses of the minerals your body actually uses: 750 mg potassium and 150 mg magnesium, not a cheap formula built around salt and sweeteners. Each serving is individually packed in a stick for convenience. We could make Kalyx cheaper. We’d rather make it better. That works out to $1.50 a stick one-time, or $1.33 with Subscribe & Save.
Is 750 mg of potassium safe?
For most healthy adults, yes. 750 mg is 16% of the 4,700 mg Daily Value, and most adults fall short of the recommended intake. But if you have kidney disease, or take medication that raises potassium, such as ACE inhibitors, ARBs or potassium-sparing diuretics, talk to your doctor before using Kalyx. Most people use one stick a day.
What if I don’t like the taste?
It’s light and smooth, not too salty. Unflavored tastes like clean mineral water; Citrus is bright lemon-lime with no nasty aftertaste, because we use no stevia or sweeteners. If it’s not for you, the 60-day guarantee covers you.
How fast does it ship?
Ships in 1–2 business days, and shipping is free.
What if it’s not for me? Can I cancel?
Drink it for up to 60 days. If it’s not your new daily habit, email us for a full refund. Subscribe & Save ships monthly; skip, pause or cancel anytime.
Why more potassium than sodium?
Most people already consume plenty of sodium and fall short on potassium, so Kalyx flips the usual formula: 750 mg potassium to 500 mg sodium, about 1.5 to 1.
Why 150 mg of magnesium?
Many Americans fall short of the magnesium RDA (420 mg for men, 320 mg for women), and you lose some in sweat. 150 mg is 36% of the Daily Value.
Will Kalyx break a fast?
No. There’s no sugar, no sweetener and no carbs from fillers, so it has essentially zero calories. Many people use electrolytes while fasting.
Is Kalyx keto and vegan friendly?
Yes to both. It has zero sugar and zero carbs, so it’s keto friendly. It’s all minerals (plus natural citrus flavor in Citrus), with no animal-derived ingredients.
How do I use Kalyx?
Mix one stick into 16 oz of water and shake or stir. Unflavored also blends into smoothies or coffee.
