About Buoy

Buoy is an American brand specializing in functional liquid supplements, designed to enrich any everyday drink with essential minerals and electrolytes. Its positioning is based on a simple observation: the vast majority of the population lacks essential minerals, due to soil depletion and the industrial treatment of water.

The range is divided into two complementary worlds. The Ocean Electrolytes offer liquid electrolytes sourced from the deep ocean, with no sugar, no sweetener and no flavoring. The Rainforest Wild Foods offer wild superfoods hand-harvested in the Australian rainforest, freeze-dried to preserve 97% of their nutritional density.

Transparency is at the heart of Buoy's approach: every batch is tested by independent third-party laboratories, the results are published online, and the absence of microplastics is confirmed by analysis. The range is recommended by more than 900 doctors and dietitians, and a university clinical study validates the hydrating effectiveness of the electrolytes.

The Buoy Ocean Electrolyte Kit recommended by our LMC testers

The Ocean Electrolyte Kit is Buoy's flagship product and the best entry point into the range. It brings together seven liquid products in a single purchase: Hydration Drops, Digestion Drops, Brain Health Drops, Rescue Drops, Energy Drops, Immunity Drops and the Rescue Salt. That's 265 servings in total for a full month-long protocol, at a rate of 4 to 7 intakes per day.

What sets this kit apart from the rest of the market is, above all, its formula. The Hydration Drops deliver 87 ionic trace minerals extracted from the deep ocean, with no heat treatment or chemical solvent. The salt used in the Rescue Salt is hand-harvested and solar-evaporated, which naturally preserves all of the co-minerals present.

Each product in the kit meets a specific need: basic cellular hydration, digestive support without FODMAPs, mental clarity, intense recovery, gentle energy without synthetic caffeine, daily immunity. All in a liquid format, compatible with any drink, coffee, tea, smoothie or water.

The value for money is consistent: on subscription, the kit comes to $0.29 per serving, i.e. about $1 per day for a complete protocol. A university crossover study confirms that Buoy electrolytes hydrate 64% better than water alone and 49% better than a major competitor on the market.

Buoy customer reviews

Customer feedback on Buoy is overall very positive, with an average rating of 4.7/5 across more than 11,200 verified reviews published directly on the official website. This is a significant volume that reflects a community of loyal and committed users, particularly among people with chronic illnesses.

The points most often cited as positives are the convenience of the liquid format, the compatibility with all drinks and the total absence of additives. Many users highlight a reduction in chronic fatigue, better management of bloating with the Digestion Drops, and relief from recurring headaches with the Hydration Drops.

Among the most striking feedback, several people with POTS, lupus or Crohn's disease report a notable improvement in their daily hydration quality. The lifetime discount program for chronic illnesses is regularly cited as a strong gesture by the brand toward its community.

The few points of attention concern the subtle mineral taste in still water, perceptible to some sensitive palates. Some users also note a slight transition effect in the first few weeks, consistent with a gradual mineral rebalancing. Nothing that calls into question the overall quality of the product.

Buoy's refund conditions if you are not satisfied

My quick take on Buoy

I spent several weeks testing the Ocean Electrolyte Kit day to day, and my verdict is clear: Buoy is one of the few electrolyte brands that genuinely keeps its promises on composition. No hidden sugar, no sweetener, no artificial flavoring. What the brand displays on its page is exactly what you find in the bottle.

What convinced me from the start is the consistency between the marketing message and the reality of the product. The clinical validation by an independent university study, the third-party tests published online and the support of more than 900 health professionals are not mere sales arguments: they are verifiable elements, accessible directly on the site.

On the user experience, the liquid format is a real advantage. One squeeze in my morning coffee, another in my lunchtime water: it fits effortlessly into any routine. The effects on mid-day fatigue and bloating appeared gradually, with no immediate spectacular effect, which is precisely the sign of a clean and well-dosed formula.

The price may seem high at first glance, but brought down to the daily serving on subscription, it is entirely justified given the quality of the sources and the rigor of manufacturing. The promo code BUOY537069 reduces the bill by 10% from the very first order, which is a good way to try the range with no commitment.
