Overview

Overview

Seaonic is a premium liquid electrolyte supplement designed to restore hydration, cellular function, and overall health. Unlike most electrolyte products, Seaonic provides over 78 ionic minerals in bioavailable ratios that mimic blood plasma, making it one of the most complete electrolyte solutions available.

We prefer liquid electrolytes over powders, and Seaonic delivers in a single-dose sachet, preventing nutrient degradation and preserving nutrient integrity. It’s completely free from sweeteners, flavorings, and additives, making it ideal for those who want pure, effective hydration without unnecessary fillers.

What sets Seaonic apart is its raw ocean mineral extraction process, which preserves the delicate balance of essential electrolytes. While many electrolyte supplements process minerals from salts, Seaonic sources directly from phytoplankton-rich ocean vortexes and uses a cold extraction method, ensuring maximum potency and bioavailability. Seaonic is also one of the only products to account for concentration, a key factor in how cells absorb nutrients through osmosis.

Best for Everyday Hydration
Best for Everyday Hydration

Effectiveness Score

8.2 / 10

Overview

Buoy Electrolytes offer a liquid, unsweetened electrolyte solution that’s easy to add to any drink. We appreciate its clean formulation, absence of sweeteners and flavorings, and liquid format, which we prefer over powdered electrolytes for better absorption and convenience.

However, Buoy falls short compared to Seaonic in key areas. Electrolyte concentration matters, and Buoy does not optimize balance as precisely as Seaonic. Mixing electrolytes into various beverages may also interfere with absorption, as water quality and other nutrients can interact with electrolytes.

While both products source minerals from the ocean, Seaonic extracts them raw and processes them cold, preserving full potency. Buoy, on the other hand, derives its minerals from marine salt, which may lose some bioactive properties.

Another drawback is that Buoy suggests adding electrolytes to hot drinks like coffee, but heat can degrade certain nutrients, reducing their effectiveness. While convenient, it overlooks key factors in how the body absorbs and utilizes electrolytes.

Key Features

No Artificial Sweeteners

Convenient Liquid Form

Can Be Added to Any Beverage

LMNT

LMNT

Best for High Sodium Needs
Best for High Sodium Needs

Effectiveness Score

7.5 / 10

Overview

LMNT is a popular powdered electrolyte supplement designed for hydration and performance, with a focus on high sodium levels. It’s widely used by athletes and those following low-carb or ketogenic diets due to its bold flavors and sugar-free formulation.

However, LMNT falls behind both Buoy and Seaonic in key areas. It only provides high amounts of a few electrolytes (sodium, potassium, magnesium) while overlooking the full spectrum of minerals needed for optimal health. Minerals work best when taken in the right balance, and LMNT does not account for mineral interdependencythe way Seaonic does.

We also prefer liquid electrolytes over powders, as powders naturally clump together when exposed to moisture. To prevent this, brands add anti-caking agents and flavor carriers like maltodextrin (often hidden under “natural flavors”), silicon dioxide, and citric acid, which can impact gut health and nutrient absorption. LMNT contains maltodextrin within its flavoring, which is something to be mindful of if you’re avoiding additives.

That said, if you're looking for a flavored option with strong sodium support, LMNT stands as one of the better choices, but it falls short in delivering a complete electrolyte profile.

Key Features

High in sodium, designed for hydration and endurance

Sugar-free with bold flavors

Convenient single-serve powder packets

Pros

Pros

Great for high-sodium needs, keto, or fasting

No artificial sugars

Tasty flavors for those who prefer flavored electrolytes

Cons

Cons

Limited electrolyte profile (missing key trace minerals)

Overlooks mineral interdependency

Powdered form, requiring additives to prevent clumping

Contains hidden maltodextrin in “natural flavors”

The Bottom Line

The Bottom Line

LMNT is a good option for those wanting a flavored, high-sodium electrolyte supplement, especially for keto and endurance athletes. However, it falls behind Buoy and Seaonic due to its limited mineral profile, lack of full-spectrum electrolytes, and reliance on additives like maltodextrin. If you want complete hydration with better absorption and fewer unnecessary ingredients, Seaonic remains the superior choice.

Liquid IV

Liquid IV

Best for Rapid Hydration
Best for Rapid Hydration

Effectiveness Score

6.8 / 10

Overview

Liquid I.V. is a widely recognized electrolyte drink mix that uses "Cellular Transport Technology" (CTT) to enhance hydration by utilizing glucose as a carrier molecule for faster absorption. It’s marketed as a rapid rehydration solution, making it popular among travelers, athletes, and those recovering from dehydration.

However, Liquid I.V. falls short compared to Seaonic and Buoy due to its limited electrolyte profile, high sugar content, and unnecessary additives. While glucose does play a role in mineral absorption, liquid formats such as Seaonic are absorbed through passive diffusion and do not require a glucose transporter, making them a more efficient and cleaner option for hydration.

We also prefer liquid electrolytes over powders because powders require anti-caking agents and flavor carriers to prevent clumping. Liquid I.V. contains citric acid, silicon dioxide, dextrose, and “natural flavors”, which often include hidden carriers like maltodextrin. Additionally, it contains 11g of sugar per serving, which isn’t necessary for daily hydration and can contribute to energy crashes.

While Liquid I.V. may be useful in cases of acute dehydration, its formulation lacks the mineral balance and purity needed for daily electrolyte replenishment.

Key Features

Best for Taste & Carbs

Effectiveness Score

4.0 / 10

Overview

Gatorade is one of the most widely available and affordable electrolyte drinks, making it a go-to for many people. However, when it comes to actual electrolyte replenishment and overall health, it ranks dead last compared to Seaonic, Buoy, LMNT, and Liquid I.V.

Its electrolyte profile is extremely limited, providing only sodium and potassium while lacking essential minerals like magnesium and trace elements. Instead of a balanced hydration formula, Gatorade relies on sugar (34g per bottle) as its primary hydration mechanism, making it more of a sports beverage than a true electrolyte supplement.

Beyond its outdated sugar-driven absorption method, Gatorade contains artificial colors, citric acid, preservatives, and other additives, which we avoid in daily hydration products. Unlike liquid electrolytes such as Seaonic, which use passive diffusion for absorption, Gatorade depends on glucose and artificial flavoring—a poor choice for long-term hydration and overall health.

Key Features

Cheap and widely available

Pros

Pros

Affordable
