FAQs

What makes Immunity Drops the best electrolyte drink when sick?

Immunity Drops are specifically formulated for illness recovery. Unlike sugary sports drinks, they contain zero sugar, sweeteners, or artificial flavors - making them gentle on sensitive stomachs. Each serving delivers bioavailable electrolytes and over 87 trace minerals, along with vitamins and antioxidants that support immune health. This fast-absorbing, unflavored formula allows your body to rehydrate efficiently, which is critical during vomiting, diarrhea, or fever. When you’re sick, every sip counts, and Immunity Drops ensure those sips hydrate, replenish, and restore - without adding anything your body doesn’t need.

Can I use Immunity Drops if I can’t tolerate drinking much?

Yes, Immunity Drops are ideal when your fluid intake is limited. Just add a small squeeze to a few sips of water, broth, or herbal tea. Because they’re unflavored and sugar-free, they won’t trigger nausea or upset your stomach like sweetened electrolyte drinks can. Their liquid form is quickly absorbed by the body, even in small amounts. This makes Immunity Drops a practical and gentle option for staying hydrated when drinking is difficult, helping you replenish essential minerals without the risk of overwhelming your system.

How often should I take Immunity Drops while I’m unwell?

When you're sick, it's best to take Immunity Drops consistently throughout the day to maintain hydration and electrolyte balance. Aim for 4–7 servings per day, starting in the morning and spacing them out every few hours. You can mix them into water, tea, or broth. If you’re dealing with vomiting, diarrhea, or fever, you may need additional servings to replenish lost fluids and minerals. The key is to sip steadily and regularly to support your recovery and give your immune system the hydration it needs.

Can Immunity Drops help if I have a fever but am not vomiting?

Absolutely. Even without vomiting, a fever causes fluid loss through sweating and faster breathing, both of which deplete your electrolyte levels. Immunity Drops help replace sodium, potassium, magnesium, and calcium - minerals your body needs to function properly during illness. The added immune-supporting vitamins and trace minerals also help your body combat infection. Simply add a squeeze to water or tea and sip regularly. It’s an easy way to stay hydrated and maintain electrolyte balance during a fever, helping you feel better faster.

Are there any side effects from using electrolytes when sick?

Immunity Drops are formulated to be as gentle and clean as possible, with no sugar, sweeteners, or artificial ingredients. This makes them easy to tolerate, even with a sensitive stomach. Most people don’t experience any side effects. However, if you have a health condition that affects your ability to process minerals - such as kidney disease or a specific electrolyte imbalance. It's always wise to consult your healthcare provider before starting any supplement, especially during illness. For most users, Immunity Drops provide safe, effective hydration support.

How is Immunity Drops different from home remedies or DIY rehydration drinks?

Many DIY rehydration recipes use ingredients like salt, sugar, or fruit juices, which can vary in concentration and may not provide a balanced mineral profile. Immunity Drops offer a reliable, clinical-grade formula with over 87 trace minerals, essential electrolytes, and immune-supporting nutrients. All without added sugar or flavor. This makes them faster and easier to tolerate, especially when you're sick. Unlike guesswork remedies, Buoy gives you consistency and peace of mind, ensuring your hydration efforts support - not hinder - your recovery.

Is an electrolyte drink when sick better than just drinking water?

Yes, especially if you’re losing fluids through vomiting, diarrhea, or fever. Water alone can’t replace the essential minerals your body loses during illness. Electrolyte drinks like Immunity Drops provide sodium, potassium, magnesium, and calcium—electrolytes that help your body absorb and retain fluids. This combination rehydrates you more effectively than water on its own. When sick, your body needs both fluids and minerals to recover. Buoy’s electrolyte drops give you both, without sugar or additives that could upset your stomach or slow recovery.

Can I use Immunity Drops even if I’m not severely dehydrated?

Definitely. Electrolyte imbalances can occur even with mild dehydration, especially during illness. Using Immunity Drops early—at the first signs of sickness—can help maintain fluid and mineral balance, potentially preventing more serious dehydration symptoms. They're gentle enough for daily use, and because they're flavorless and sugar-free, you can use them regularly in tea, broth, or water without overwhelming your system. Even small hydration improvements can make a big difference when your body is under stress from illness.

Are Immunity Drops safe for kids or older adults when they’re sick?

Yes, Immunity Drops are suitable for most age groups, including children and older adults. Their clean, sugar-free, and flavorless formula is gentle enough for sensitive systems, making them a smart choice for hydration support during illness. Just adjust the serving size based on age and fluid needs - typically a smaller squeeze for children. Always consult a healthcare provider if you’re using electrolyte supplements for young kids or those with medical conditions. Overall, they offer a safer alternative to sugary drinks for recovery at any age.
