Our 'No' List
No Sugar
  • Inflammatory
    Spikes glucose and insulin, feeds harmful gut bacteria, contributes to glycation of proteins

  • Dehydration
    Too much can dehydrate cells by creating osmotic imbalance
No Sweeteners
  • Artificial
    Disrupts gut microbiome, may trigger insulin response despite zero calorie, associated with metabolic issues in studies

  • Naturally-derived sweeteners
    Can trigger insulin response and blood sugar changes, highly processed despite “natural” origins, digestive disruption (especially sugar alcohols)
No Flavors
  • Artificial flavors
    Contain petroleum-derived chemicals and neurotoxic compounds, headache and allergen trigger, hidden preservatives and solvents

  • ‘Natural’ flavors
    Can legally contain 100+ undisclosed ingredients, may contain solvents and preservatives, hidden allergens and inflammatory compounds
No Additives
  • Carriers, blending agents, & others
    Create intestinal permeability ("leaky gut"), often contain hidden allergens, interfere with nutrient absorption

  • Coloring agents & dyes
    Linked to hyperactivity and behavioral issues, many derived from petroleum or coal tar, associated with allergic reactions, some classified as carcinogens
No Heat Processing or Chemical Spraying
  • Nutrient disruption 
    Destroys enzymes and heat-sensitive vitamins, denatures proteins and beneficial compounds, strips away natural cofactors needed for absorption

  • Inflammatory byproducts
    Creates inflammatory compounds (AGEs), Chemical residues accumulate in body
No Lab-Manufactured Isolates
  • Poor bioavailability 
    Poor bioavailability (10-30% vs 90%+ for whole foods), missing cofactors required for utilization

  • Overdosing
    Can create imbalances by flooding single pathways

  • Inflammatory byproducts
    Often contaminated with synthesis residues
No Animal Byproducts
  • Hidden ingredients 
    May contain hormones and antibiotics, often from diseased or low-quality sources

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 which most other electrolyte products include.

SUBTLE MINERAL TASTE
Electrolytes are salts, so on their own they taste very salty. Our competitors mask this saltiness by adding sugar, sweeteners, and "natural" flavors to their electrolytes. We spent 4 years in R&D figuring out how to deliver electrolytes with as neutral of a flavor profile as possible without adding those nasty ingredients. We achieved this goal, although there is still a very subtle mineral taste present because we do not use any sugar, sweeteners or flavors to cover it up. 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 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.

• 0 Calories
• 0 Carbohydrates
• 0 Sugar
How Long Until I 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.
Are there B Vitamins?
Rescue Salt does not contain B Vitamins.
Do Your Products Have Caffeine?
The only product that contains caffeine is our Energy Drops, which is sourced from organic green tea.

Salt in a pinch!

I love that this salt is actually helpful for the condition I have! (POTS) The small size is handy, and it actually works when used in moderation, combined with the sodium and hydration I add and use from the other Buoy products I get regularly! I honestly didn't think when I switched to Buoy for my electrolyte hydration needs, that it would work well enough to be effective AND without causing too much added sodium. Any other sodium products usually make me bloat up like a fish. I'm pleased to say that BUOY HYDRATION PRODUCTS DO NOT MAKE ME RETAIN FLUIDS, OR BLOAT. IT ACTUALLY WORKS! The salt used along with various other liquid hydration products from Buoy, is an effective combination for me that helps make a difference. And every little thing that can contribute to helping someone like me with chronic health problems, equals a HUGE WIN in my book! I am impressed. Thank you BUOY!

Enjoy the no flavor

I was getting flavor fatigue from all the other hydration drink mixes that have the high sodium I need. The rescue salt has been a nice change and also an easy solution to getting more sodium daily.
