Why Choose Buoy?

Buoy's Clinical Study

Why Water Isn’t Enough

In the study, Buoy was 64% more hydrating than water based on biomarkers like plasma osmolarity, urine concentration, and beverage hydration index. Water alone doesn’t supply the electrolytes your body needs for full hydration.

How Other Electrolytes Fall Short

Buoy was 49% more hydrating than a leading electrolyte product. Why? Most alternatives include sugar, artificial sweeteners, improper electrolyte ratios, and flavorings that trigger a diuretic response, reducing hydration.
The Problem with Large Electrolyte Doses
High-dose electrolyte drinks may cause the body to expel water via urination to protect against high salt levels. Buoy’s balanced formula avoids this problem by supporting retention rather than elimination.

How the Study Was Conducted

This study was one of only six to measure ingestion rate, electrolyte ratios, and hydration efficacy using clinically accepted biomarkers. It used both subjective and biological indicators of hydration, not just self-reported results.

Why Buoy Sets a New Standard for Hydration

  • Naturally balanced electrolyte ratios

  • Bioavailable liquid form for faster absorption

  • Harvested (not synthesized) mineral sources

  • Zero sugar, flavors, or sweeteners

  • Microplastic-free and third-party tested
How Buoy Compares to Competitors
Unlike powders, tablets, or sugary sports drinks, Buoy’s clean formula delivers better hydration without additives that interfere with performance or digestion.

FAQs

What makes Buoy electrolytes clinically proven?

What makes Buoy electrolytes clinically proven is a third-party, university-led clinical trial that measured hydration performance using biomarkers in blood and urine. The study found Buoy to be 64% more hydrating than water alone and 49% more hydrating than a leading electrolyte competitor. These results were based on net fluid balance, plasma osmolarity, and beverage hydration index, making Buoy one of the few electrolyte brands with scientific validation of its efficacy.

How does Buoy compare to water for hydration?

Buoy is 64% more hydrating than water, according to a clinical trial that measured biological hydration markers. While water is essential, it doesn’t replace the electrolytes lost through sweat, illness, or daily activity. Buoy adds sodium, potassium, and other essential minerals that help your body absorb and retain fluids more effectively, leading to improved net fluid balance and better overall hydration.

Why is Buoy more effective than other electrolyte drinks?

Buoy is more effective than other electrolyte drinks because it avoids sugar, stevia, artificial sweeteners, and synthetic ingredients that can reduce hydration efficiency. In a clinical study, Buoy was 49% more hydrating than a top competitor thanks to its clean formula and properly balanced electrolyte ratios. Other products often cause a diuretic response or spike in blood sugar, while Buoy supports fluid retention and cellular hydration without side effects.

What hydration markers were measured in Buoy’s clinical trial?

The hydration markers measured in Buoy’s clinical trial included net fluid balance, plasma osmolarity, urine osmolarity, and beverage hydration index (BHI). These biomarkers provide a comprehensive picture of how well a drink hydrates the body. Buoy showed significant improvement in all of them, confirming its superior ability to help the body retain water and electrolytes compared to both water alone and other leading electrolyte brands.

Does Buoy help retain more water in the body?

Yes, Buoy helps retain more water in the body. The clinical study reported a 10x increase in net fluid balance with Buoy compared to water alone. That means your body is holding onto more of the water you drink, rather than quickly excreting it. This is especially important during exercise, travel, illness, or hot weather when maintaining hydration is critical.

Is Buoy safe for daily hydration?

Buoy is safe for daily hydration and designed to integrate seamlessly into your routine. It contains zero sugar, zero artificial ingredients, and uses naturally sourced electrolytes and trace minerals. Because it’s bioavailable and doesn’t overload the body with high-dose salts or sweeteners, Buoy supports hydration without causing bloating or digestive upset. It’s suitable for athletes, busy professionals, or anyone needing consistent hydration.

What makes Buoy’s electrolyte formula unique?

What makes Buoy’s electrolyte formula unique is its clean, sugar-free composition combined with deep ocean electrolytes and 87+ ionic trace minerals. Unlike powders and tablets, Buoy is a liquid that dissolves instantly and absorbs quickly. It’s bioavailable, sustainably sourced, and free from sweeteners or flavorings that can disrupt hydration. This balance allows Buoy to hydrate more effectively without triggering water loss or sugar spikes.
