Drinking water alone after sweat loss often leads to over-urination — your body dumps fluid because the salt-to-water ratio is off.
A foundational randomized trial in the European Journal of Applied Physiology showed that sodium-containing rehydration drinks restored fluid balance significantly better than plain water, with retention rising as sodium concentration rose.

During endurance exercise — especially in heat or beyond 60 minutes — sodium intake helps maintain plasma volume, sustain performance, and lower the risk of hyponatremia.
The American College of Sports Medicine's joint position stand recommends sodium-containing fluids during prolonged exercise to delay fatigue and protect performance.

Exercise-associated muscle cramps in salty sweaters are tightly linked to sodium and chloride deficits — not magnesium alone, not "dehydration" alone.
A double-blind crossover trial in the Journal of the International Society of Sports Nutrition found that supplemental electrolytes significantly reduced cramp susceptibility compared to plain water.

Mild dehydration — as little as 1.5–2% body water loss — has been shown to impair concentration, working memory, and mood, even at rest.
A randomized crossover study in the British Journal of Nutrition demonstrated that 1.6% dehydration significantly degraded vigilance, working memory, and tension — all reversed with proper rehydration.

When sodium is replaced during exercise in the heat, the body holds plasma volume better — meaning lower core temperature, lower heart rate at the same workload, and longer time to exhaustion.
Research in the Journal of Athletic Training demonstrated electrolyte ingestion attenuates the rise in core body temperature during prolonged heat exercise compared to water alone.

The sodium–potassium ratio — not sodium alone — is the strongest dietary predictor of healthy blood pressure. Most modern diets deliver too much sodium and far too little potassium.
A 2013 BMJ meta-analysis pooling 22 randomized controlled trials concluded increased potassium intake reduces systolic blood pressure by 3.49 mmHg and diastolic by 1.96 mmHg in adults with hypertension.

The average adult loses 500–1,500 mg of sodium per liter of sweat — and significant potassium and magnesium along with it. Replacing what you lose isn't optional; it's how your nervous system, heart, and muscles keep firing.
Ingredients: Ancient lake salt, potassium chloride, magnesium chloride solution.
No fillers. No artificial anything. Just three pure minerals in their most bioavailable form, potassium naturally sourced from the Dead Sea and magnesium from ancient Australian salt lakes.
This precise electrolyte blend supports fluid balance at the cellular level, keeps muscles firing without cramping, and maintains the mental clarity that disappears when you're depleted. Whether you're deep into a training session, grinding through a work day, or fasting, your body runs better when its minerals are topped off. Clean. Unflavored. Works in anything.

Matt Maruca | Founder, Ra Optics
I love Sol Dept. I really appreciate Sol’s focus on offering the highest quality, non-toxic products while actually making them elevated and premium, not just some kind of health gimmick. So in the end you're not making any compromises. You're getting a better product and a better result for your health.

Been using Aurum's Magnesium daily and the calm + deep recovery is unreal. Feels like my nervous system settling & operating without tension. Perfect addition to my evening ritual for stillness, recovery, deep sleep & helps me in my healing sessions with clients to connect to source.
Marcel Schaar
Sol Dept is the place for everything high quality. Best tasting and formulated electrolyte salt. Liquid magnesium that instantly hits. Shorts with the best cut. Soap that doesn’t nuke your hormones. Literally no one else does it like this. I don’t want to miss OJ or milk without aurum salt and magnesium anymore.
Jeremy (aka VanMan)
Sol shorts are my daily driver. Wear them lounging, working out, or pretty much any other time. Probably wearing them 75% of my waking hours. Perfect product.
The Great Dane
Whether I’m hitting the gym, going on a hike, or just looking for a good night’s sleep, Sol Department has the essentials. My Sol Shorts have been with me from coast to coast, and Aurum Salts and Magnesium are daily staples. I cannot speak to the quality of all items enough!
Melker Svärd CEO of Wyde Footwear
Sol Dept is one of the few brands I genuinely use daily and across categories: shorts, soap, electrolytes and been doing it for years now. As a founder I’m probably more critical than most, and what stands out is the obsession with doing things properly. No shortcuts, only the best materials and ingredients.
Coach Paul
I hate getting clothes that I only wear once or twice. But I wear these all the time, even when I lift hard.
Jonas Kilker
I love Sol Department because it is a one stop shop to help me live a natural and vitalistic lifestyle. The clothing, the supplements, the soaps are all things I genuinely use on a daily basis and to have all those necessities come from a source that I trust is everything. That’s why I’ve returned to Sol Dept products year after year.
You drink water all day and still feel drained. That's not a hydration problem — it's a mineral problem. Plain water and sugary sports drinks pass right through you. These ancient salts give your cells what they actually need to absorb it: pure, bioavailable minerals that keep your brain sharp, your muscles loose, and your energy steady. No fillers. No artificial anything. Just the missing link.
Just stir a small pinch (1/2 teaspoon or 3g) or a couple of shakes into a tall glass or a reusable bottle of water. It dissolves fast, turning your regular drink into a powerhouse of minerals that actually gets absorbed. If you want a little extra flavor, it tastes great with a squeeze of fresh lemon or lime over some ice.

It means an independent lab verified exactly what's in this product and what isn't. Both the lake salt and the magnesium components have full elemental analyses published on this page. Every element tested, every result shown. Arsenic, lead, mercury, cadmium — all not detected. We don't ask you to trust the label. We show you the data.
Minerals sourced from ancient lakes and sea beds carry a real risk of contamination, arsenic, lead, mercury, and cadmium can all occur naturally in these environments. We test for all of them. The results are published right here on the page: not detected across the board. Clean source, verified clean product.
Flow agents like silicon dioxide, magnesium stearate, or calcium silicate are synthetic additives used in most powder supplements to stop clumping during manufacturing. They make the production process easier — but they have no business being in what you put in your body. These salts contain three things: sodium, potassium, and magnesium. That's it.
