Buoy's Clinical Study

What Causes Leg Cramps?

Leg cramps are often caused by dehydration and mineral deficiencies—especially in sodium, potassium, chloride, and magnesium. Even a 2% loss in fluids and electrolytes can impact muscle function. Buoy’s electrolyte drops help replenish what’s lost, naturally and efficiently.
How Electrolytes Help With Cramping
Electrolytes support muscle contraction and relaxation. Without them, cramping becomes more likely. Buoy delivers ionically charged minerals your muscles need to function - without sugar or fillers that hinder absorption.
Sports Drinks vs. Electrolyte Drops for Leg Cramps
Most sports drinks fall short for daily electrolyte support. They often use:

• Processed salts with anti-caking agents
• High sugar content that undermines hydration
• Artificial colors and flavors that do more harm than good

Buoy skips all of that. It’s sugar-free, filler-free, and uses naturally sourced deep ocean minerals, ideal for anyone seeking consistent support against leg cramps.
How Buoy Compares to Powders and Tablets
Unlike powders or dissolvable tablets, Buoy’s liquid format is fast-absorbing and portable. It blends with any drink and avoids the gritty texture or settling you might get from other formats. One squeeze delivers effective hydration where it counts.
Why Active People Choose Buoy for Leg Cramp Relief
Daily tasks, not just workouts, can lead to electrolyte loss. Whether you’re training or working long hours on your feet, Buoy makes it easy to stay hydrated and avoid muscle cramping, without reaching for sugary sports drinks.

What Makes a High-Quality Electrolyte Drink?

Salt Source
85% of an average American's sodium intake comes from nutrient sparse sources like the cheap and processed salts found in sports drinks and traditional electrolyte products.

👎 Sodium Bicarbonate
👎 Sodium Chloride
👍 Real Sea Salt
Naturally-Balanced Electrolytes
Sodium, potassium, chloride and magnesium are the essential electrolytes needed for optimal hydration.

Getting all of these in their naturally occurring ratios—like from harvested sea salt—makes for easy absorption as its the way we've hydrated for centuries before modern society.
Ionic Trace Minerals
Modern agriculture and commercial water have stripped our food and water of essential trace minerals, making them hard to find even in balanced diets.

Buoy is packed with 87 trace minerals that nurture well beyond the label and facilitate energy generation and muscle health.
B Vitamins
Did you know some vitamins can help you hydrate better?

Buoy's curated blend of plant-powered B vitamins that support routine electrolyte function.

FAQs

What are electrolytes?

Electrolytes are charged ions that conduct electrical activity in our bodies . These minerals are crucial to everyday bodily functions and the principle electrolytes are sodium, potassium, chloride and magnesium.

Why are electrolytes important?

Electrolytes are vital nutrients that support whole-body health. From our mood to our muscles and ability to detox, electrolytes play a key role in over 300 enzymatic reactions in our body that benefit daily life.

What causes leg cramps?

Leg cramps are often caused by imbalances in key electrolytes- especially sodium, potassium, magnesium, and calcium. These minerals help muscles contract and relax properly. When levels drop, usually due to dehydration, intense exercise, excessive sweating, or poor nutrition, your muscles may spasm or cramp. Factors like age, medications (like diuretics), or conditions such as diabetes and pregnancy can also increase your risk of electrolyte depletion and leg cramps. Staying hydrated and keeping your electrolyte levels stable is a smart way to reduce your risk.

How can electrolyte drinks prevent leg cramps?

Electrolyte drinks help replenish the minerals your body loses through sweat, urination, or daily activity. Unlike plain water, they restore sodium, potassium, magnesium, and calcium - essential for proper muscle contraction. Studies have shown that drinking electrolyte-enhanced fluids is more effective than water alone at relieving and preventing muscle cramps. Buoy makes this even easier with no-sugar, flavorless electrolyte drops you can add to any drink. Whether you’re active or not, keeping your electrolyte levels balanced can dramatically reduce cramping.

Can I drink electrolyte drinks if I'm not an athlete or work out regularly?

Absolutely. Leg cramps don’t just affect athletes - many people experience them due to dehydration, medications, pregnancy, or poor sleep. Buoy is designed for all-day hydration and mineral replenishment, not just for sports. Our drops support everything from hydration and muscle comfort to focus and mood. If you’re waking up with leg cramps, experiencing spasms at your desk, or dealing with restless legs at night, electrolyte drinks can offer real, everyday relief - even if you’re not hitting the gym.

Are your electrolyte drinks low in sugar?

Buoy electrolyte drops are completely sugar free as well as sweetener free. We're proudly unflavored and unsweetened.

Do your electrolyte drinks contain artificial colors or flavors?

No!

Buoy differentiates its electrolyte drops from other products because of how clean are ingredient sourcing is.

How do I know if I'm dehydrated?

One of the easiest ways to tell if you're dehydrated is by the color of your pee.

The colors of your pee can range from clear to a dark amber. If you're dehydrated, your pee will be a noticeable yellow or amber color.

An additional method to test how hydrated your are is assessing your skin elasticity. Pinch the skin on your wrist and then let go. If your skin takes a second to return to normal, you may be dehydrated.

What to do if I'm dehydrated?

Once dehydrated, water alone is not enough. Drinking an electrolyte-infused beverage is key to replenishing lost electrolyte levels and balancing your fluids.

Buoy's electrolyte drops are a quick, easy way to rehydrate with any beverage you're drinking.

Can I drink your electrolyte drinks while pregnant or breastfeeding?

Yes!

Electrolytes and trace minerals are key nutrients that are essential to all cycles of pregnancy, from pre- to postpartum.

Pregnant and breastfeeding women can significantly benefit by incorporating a clean electrolyte supplement into their diets.

With any new supplement, we always recommend checking with your healthcare team or doctor.

Can children drink your electrolyte drinks?

Yes!

All Buoy electrolyte drops are safe and effective for children.

Buoy contains only essential electrolytes and trace minerals important for every cell and system in our bodies, especially key for children as these nutrients are often missing in our diets.

Other electrolytes contain high sugar and sweetener counts, artificial colors and additives and other inflammatory ingredients.

Do your electrolyte drinks contain caffeine?

Hydration Drops and Immunity Drops do not contain any caffeine.

Only our Energy Drops contain a small amount of caffeine sourced from the potent health compounds in green tea.

How long do the effects of your electrolyte drinks last?

Buoy electrolytes are a great option for short-term relief with their fast-acting, bioavailable form factor. For results within a day or two, you can help prevent leg cramps, headaches, fatigue and more.

Use consistently for transformative, long lasting benefits.

Are your electrolyte drinks vegan?

Yes!

Buoy's electrolytes and minerals are ethically sourced from the ocean and our antioxidants and vitamins are plant-powered.

Our electrolyte drops contain no animal byproduct.

Do you offer bulk orders or subscriptions for your drinks?

Yes!

If you need to stock up, 9 Bottle Packs are available for one-time purchases and subscription to save an additional 24%.

What is the shelf life of your electrolyte drinks?

Buoy electrolyte drops are shelf stable over a year.

After opening, we suggest using within two months.

What are the best electrolytes for leg cramps?

Magnesium and potassium are often the most helpful electrolytes for reducing leg cramps, especially nighttime cramps or those caused by exercise. Sodium and calcium also play a supporting role. Magnesium, in particular, helps relax muscles and prevent spasms, while potassium keeps nerve and muscle cells functioning properly. Buoy’s Hydration Drops contain all four of these essential electrolytes in balanced, bioavailable forms - without sugar or additives - making it an effective choice for fast relief and prevention.

Can electrolyte imbalance cause leg cramps?

Yes. An electrolyte imbalance is one of the most common causes of leg cramps. When key minerals like sodium, potassium, or magnesium fall out of range, your muscles can contract abnormally, resulting in painful cramps. This is especially likely during or after intense activity, illness, or hot weather, when fluid loss increases. Replenishing your electrolytes with something like Buoy’s drops can help restore balance quickly and reduce the frequency or severity of cramps.

Are nighttime leg cramps related to dehydration?

In many cases, yes. Nighttime leg cramps, especially in older adults, are often tied to mild dehydration and low electrolyte levels. As your body loses fluids throughout the day and you go hours without replenishing during sleep, electrolyte levels can drop just enough to trigger muscle spasms. Adding an electrolyte drink like Buoy to your evening routine can help prevent this by supporting proper muscle relaxation overnight.

Do electrolyte drinks help with pregnancy leg cramps?

Pregnancy leg cramps are common, especially in the second and third trimesters. They’re often linked to changes in circulation, increased fluid needs, and shifting mineral levels, particularly magnesium and calcium. Drinking electrolyte-enriched fluids can help balance these minerals and reduce cramping. Buoy’s drops are caffeine-free, sugar-free, and safe to use during pregnancy, making them a gentle and convenient option to stay hydrated and comfortable.
