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 Your B Vitamins Methylated?
Methylation is typically in reference to Vitamins B9 and B12 because of cheap, widely used and non-absorbable forms these specific vitamins. These vitamins are not used in any Buoy products.

The B Vitamins used in Buoy typically do not come in a methylated form (there is a rare B6 form floating around but is not standard or widely used).

For the vitamins used, Buoy sources the cleanest, most absorbable forms of B1, B5, and B6. Methylation is typically a term used with B vitamins that aren't in Buoy.
Do Your Products Have Caffeine?
The only product that contains caffeine is our Energy Drops, which is sourced from organic green tea.

Helps keep me hydrated with +3 day water fast

I usually partake in a 3 or more days water fast twice a year. These drops added to my water have helped stave off hunger pangs and headaches I used to feel without the electrolytes. It’s goood stuff and very useful for an elongated fast

Buoy Hydration Drops

I tried Buoy Hydration drops a few years ago, probably around the time they were initially introduced. I had been searching for unflavored electrolyte drops for a while and was happy to see Buoy offered by Grove. The difference in the way I felt was almost immediate. No more brain fog, no more muscle cramps! I've been actively advocating for my family and friends to use them ever since. One friend has IBS and since beginning the digestion drops has been symptom free. I can't thank you enough for caring enough to create something so beneficial!
