Will I taste anything?

Buoy is purposefully unflavored, which means we do not hide behind the sweet and inflammatory ingredients like sugar, stevia, dextrose and "natural" flavors other electrolytes do.

SUBTLE MINERAL TASTE

Hydration Drops harvest electrolytes and minerals in their most bioavailable form. While many people don't notice a taste in most beverages, everyone's palette is different and so you may notice hints of a subtle mineral flavor.

A LITTLE GOES A LONG WAY

One serving is a single, short squeeze into a full beverage. Each serving contains a ⅓ of the electrolyte content of a sports drink.For those noticing a strong taste, you've likely squeezed too much into a single beverage or a half-full beverage.

Will Buoy break my fast?

Nope!

Unlike other electrolytes, Buoy will not change your metabolic state regardless of how many servings you use.

How long until you see results?

Buoy’s hard-to-find essential nutrients are important for foundational health in the long run.

Depending on how chronically dehydrated you are when you start Buoy will affect how intense of a feeling you might notice. Headaches, cramping, midday fatigue, grogginess and drier skin are all symptoms of dehydration.

AFTER A WEEK

While a lot of people using Buoy notice results after about a week of consistent use, some don’t—and that’s okay.

AFTER A MONTH

It can take up to a month or two for your body to reach a new normal. Rest assured, our high bioavailable and fast-absorbing ingredients get to work quickly and target nutrient gaps in the American diet.

Do your products have caffeine?

Hydration Drops does not contain caffeine.

The only product that contains caffeine is our Energy Drops, which is sourced from organic green tea.

Rescue Salts - the name couldn't be more true!

I have POTS (a form of dysautonomia) with various comorbidities and already use Buoy's hydration drops everywhere I can. This salt now allows me to add even more electrolytes throughout my day. I can add the salt to my breakfast and the drops to my coffee! The salt also helps if you're in a pinch and don't have a beverage hanging around. It's much nicer carrying a glass jar than salt packets for when I get lightheaded. Plus, it really does feel different than regular salt - like it dissolves quicker on your tongue, so you don't have to chew the gritty bits of normal salt. Give it a try, I doubt you'll be disappointed and it could be a total game changer!

Rescue Salts

First of all shout out to Buoy for being an all around stand up company that gives me all the feels. Great customer service, branding, messaging, chronic illness support, inclusion etc... AND great products. I have I.C. and other chronic inflammatory disorders, staying hydrated is important and difficult. I first tried the Buoy hydration drops and LOVED the energy and uplifted mood, but I noticed my I.C. flaring up. I assumed it was due to the b vitamins since I've been sensitive to them in the past. So I reached out to Buoy explaining that I loved how the drops made me feel energy and mood wise, and did they have a product without the b vitamins. Of course, they had a solution - rescue salts! These are great because you can use them like table salt and add them to food and drinks! They only downside is they are tricky to dispense in a hurry. The best news is that I figured out the lowest effective dose of the hydration drops and I am now able to get the benefits of hydration, energy, elevated mood without any increased inflammation. After testing a retesting so many electrolytes I have learned that salt itself is an irritant to the gut when you're taking more than you need. I'm not running marathons or doing crossfit haha I only need 1 serving of Buoy per day and I am golden. Thanks again Buoy!

Good stuff!

Like other Buoy products, this is a game changer.

Night leg cramps are my issue. These salts, taken later in the day, give me night time relief from sleep disrupting cramps. The salt crystal form makes it easy to take in. I add it to my afternoon tea but also like to sprinkle it on bread and butter at dinner. Bravo Buoy!

So good!! Couldn’t recommend it high enough

I’ve been doing triathlons for a few years and have started using electrolyte and salt tablets during training- started using LMNT months ago because I thought it was the saltiest best choice but then I FOUND BUOY! Learned a bunch about how where salt is sourced/manufactured can affect the way your body uses it and love that rescue salts dont cut corners. These keep me cramp free and oh so happy during training. Subscribed!

My New Partner in Crime (Baking)

Obsessed. I originally got this to treat my chronic dehydration but I LOVE using it in the kitchen!! The salt is almost like powder or dust- it's so fine and so you get the little perfect bit in every bite! I trust everything buoy does because they are the GOAT when it comes to clean ingredients but this takes it to a whole new level!
