Buoy Electrolyte Drops for POTS: An In-Depth Review

Among the growing number of electrolyte products marketed to people with POTS and dysautonomia, Buoy has carved out a distinctive niche: unflavored, liquid-concentrate electrolytes derived from ocean minerals that can be added to any beverage without altering its taste. For patients who struggle with taste fatigue from flavored powders, who have MCAS or food sensitivities that make most commercial electrolytes problematic, or who simply want to maintain consistent hydration throughout the day without committing to a specific flavor, Buoy offers a genuinely different approach.

This review covers both Buoy products relevant to POTS patients — the standard Hydration Drops and the higher-sodium Rescue Drops — along with an honest assessment of their strengths, limitations, and the community feedback that has emerged from the POTS and dysautonomia patient communities.

The Two Products: Understanding the Difference

Buoy makes two electrolyte products that are relevant to POTS patients, and it is essential to understand that they are formulated for different purposes.

Buoy Hydration Drops

The original Buoy product is a liquid concentrate derived from ocean water and supplemented with B vitamins. Each serving (one short squeeze from the dropper bottle) contains:

• Sodium: 50 mg
• Potassium: 10 mg
• Magnesium: 5 mg
• Vitamin B1 (Thiamine): 0.3 mg
• Vitamin B2 (Riboflavin): 0.3 mg
• Vitamin B3 (Niacin): 4 mg
• Vitamin B5 (Pantothenic acid): 1 mg
• Vitamin B6 (Pyridoxine): 2 mg (150% DV)
• Vitamin B12: 0.6 mcg
• Plus 87 trace minerals from ocean sources

The Hydration Drops are designed to improve the quality of hydration from any beverage — they enhance cellular water uptake through the trace mineral content and support energy metabolism through the B vitamins. For general wellness and hydration optimization, they are well-regarded. For POTS sodium loading, the 50 mg of sodium per serving is far too low to serve as a primary electrolyte source. A patient would need to consume approximately 40 servings to reach 2,000 mg of supplemental sodium — clearly impractical.

Buoy Rescue Drops

Buoy Rescue Drops are the product specifically designed for high-sodium needs, including POTS. Each serving contains:

• Sodium (as Sea Minerals): 300 mg
• Chloride (as Sea Minerals): 480 mg
• Potassium: 20 mg
• Magnesium: 3 mg
• Calcium: 3 mg

The Rescue Drops contain no sugar, no sweeteners (including stevia and monk fruit), no flavors, no artificial ingredients, and no major allergens. Like the Hydration Drops, they are completely unflavored and can be added to any beverage. The sodium content of 300 mg per serving is meaningful — six to seven servings throughout the day provides approximately 1,800–2,100 mg of supplemental sodium, which combined with dietary sodium can help many POTS patients reach their daily target.

The Clinical Evidence

Buoy has conducted a university-led, crossover-design clinical study on their electrolyte products. The study found that Buoy electrolytes hydrate 64% more effectively than water alone and 49% more effectively than a leading competing brand. The study measured hydration status through urine specific gravity — a standard indicator of how concentrated or diluted the urine is, which directly reflects hydration status.

This clinical evidence is meaningful. It demonstrates that the mineral composition of Buoy products genuinely improves fluid retention compared to plain water — the mechanism being that the electrolytes, particularly sodium, draw water into the vascular space and slow renal excretion. For POTS patients, this improved fluid retention is directly relevant to blood volume maintenance.

The Chronic Illness Discount

One of Buoy's most practically significant features for the POTS community is their Chronic Illness Support Program, which offers a 35% lifetime discount on all Buoy products for patients with qualifying conditions. POTS, dysautonomia, EDS, MCAS, ME/CFS, and many other chronic conditions qualify. The application process takes approximately two minutes at justaddbuoy.com/pages/chronic-illness-support, and approval is typically rapid.

At the standard price, Buoy Rescue Drops cost approximately $30 for a bottle providing 120 servings — roughly $0.25 per serving. With the 35% chronic illness discount, this drops to approximately $0.16 per serving, making it one of the most cost-effective high-sodium electrolyte options available. The company also offers subscription pricing (23% off) that can be combined with the chronic illness discount for maximum savings.

What the POTS Community Says

Community feedback on Buoy from POTS and dysautonomia forums is generally positive, with several recurring themes:

What patients love:

• The unflavored format is genuinely unique and highly valued by patients with taste sensitivities or MCAS
• The ability to add drops to coffee, tea, or any preferred beverage makes consistent use much easier
• The clean ingredient list (no sweeteners, no artificial ingredients, no major allergens) is important for patients with multiple sensitivities
• The chronic illness discount makes it accessible for patients managing significant healthcare costs
• Many patients report meaningful symptom improvement, particularly reduced dizziness and improved energy

What patients flag as concerns:

• The standard Hydration Drops contain 150% of the daily value of vitamin B6 per serving. High-dose B6 supplementation over time has been associated with peripheral neuropathy (B6 toxicity) in some individuals. Patients who take multiple servings per day, who are already supplementing B6, or who have small fiber neuropathy should be aware of this and discuss it with their provider. The Rescue Drops should be checked for their specific B6 content.
• The Rescue Drops have a 15:1 sodium-to-potassium ratio, which some community members have flagged as potentially imbalanced for patients who are already low in potassium. Patients with known potassium deficiency or those on medications that affect potassium levels should monitor their potassium intake separately.
• The sodium content of 300 mg per serving, while meaningful, still requires multiple servings per day to reach POTS sodium targets. Patients with very high sodium requirements may need to combine Buoy with other sources.

Honest Assessment

Buoy Rescue Drops are a genuinely excellent product for POTS patients who prioritize a clean, unflavored, flexible electrolyte option. The clinical evidence for improved hydration is real, the ingredient list is among the cleanest available, and the chronic illness discount makes it financially accessible. The unflavored format is a significant practical advantage that no other major electrolyte brand currently matches.

The limitations are real but manageable: the sodium content per serving requires multiple daily doses to reach therapeutic targets, and the B6 content in the standard Hydration Drops warrants attention for patients who are sensitive to this vitamin. For most POTS patients, Buoy Rescue Drops are best used as part of a broader hydration strategy — combined with dietary sodium, salt tablets when needed, and other electrolyte sources — rather than as a standalone solution.

For patients with MCAS, multiple food sensitivities, or strong taste aversions to commercial electrolyte products, Buoy Rescue Drops may be the best available option on the market.
