Why electrolytes and trace minerals matter more than most people realise
The human body is 60 to 70 percent fluid. That fluid is not simply water — it is a precisely balanced mineral solution that governs how every cell functions. Electrical signals, nutrient transport, muscle contraction, nerve conduction, hormonal regulation: all of it depends on the right minerals being present in the right ratios.
This is not a supplement category. It is a foundational category. The mineral balance of your internal fluid is a blueprint that took hundreds of millions of years to refine — from single-celled organisms to the trillions of cells that make up a human body. When that balance is disrupted, everything downstream is affected.
At Healthy Habitat, we rarely recommend supplements. We believe most health gains come from removing what's working against you — not adding more to compensate. But this category is different — and for more than one reason.
Most of us are already mineral deficient before we even consider supplementation. Modern agricultural soils are a fraction of the mineral richness they held a century ago. Water filtration — which we strongly encourage — removes contaminants but also strips naturally occurring minerals. And modern life places demands on the body that our ancestors simply did not face: chronic stress, poor sleep, environmental toxins, and relentless cognitive load all accelerate mineral depletion.
This is not a category we recommend lightly. It is one we recommend because the case is clear: the modern environment makes mineral deficiency the default, not the exception. Addressing it is not optimisation — it is maintenance.
Whether you are an athlete pushing your limits, an office worker trying to think clearly, a parent managing energy through a long day, or someone who simply wants to support their health as they age — the question is the same: what is the cleanest, most complete way to maintain the mineral balance your body depends on?
What most electrolyte products get wrong
Most products in this category are formulated around palatability, not biology. They taste good. They mix easily. But the ingredient list tells a different story.
How each product performs — by use case
Rather than a simple ranking, we evaluated each product across four use cases. The pattern that emerges tells the real story.
The pattern: Every other product leads one use case at best, and falls short in the others. Seaonic finishes in the top two across all four — the only product in this review to do so. That consistency is not a coincidence. It is the result of building around what the body actually needs, rather than around what tastes good or sells well.
Seaonic — The Overall Pick
The only product that places in the top two across every use case
Seaonic is the product this review kept returning to — and the reason it stands apart is not one single thing, but the combination of everything done right at once.
It is the only formula in this comparison that provides both a complete primary electrolyte profile — sodium, potassium, magnesium, calcium — and a full spectrum of 70+ ionic trace minerals, in a single-ingredient liquid with zero additives. No citric acid. No natural flavours. No stevia. Nothing that is not there for a biological reason.
The mineral ratios in Seaonic closely mirror those found in human blood plasma — a blueprint refined over hundreds of millions of years of evolution. Ionic minerals do not require breakdown in the gut. They are already in solution, which means the body can use them immediately. This is not a marketing claim. It is the reason the product works as well as it does across such a wide range of users.
The hypertonic formulation is designed for periods of high physical or mental demand — intense training, a long day on your feet, travel, heat, or any scenario where your body is under significant load. The isotonic formulation suits everyday use: morning hydration, office workers, older adults, children. Each 10ml sachet is taken straight — no mixing, no powder clumping. You take it before a hard session or alongside your morning water with equal ease.
And sometimes, less really is more.
Seaonic is the most expensive product in this review. We think it is worth it. This is one of those foundational products — like a good water filter or a quality mattress — where the case for spending more is straightforward. On subscription or bundles, the price comes down meaningfully. You can save money elsewhere. On the thing that makes up 60% of your body, it is worth getting right.
The rest of the field — and where each one fits
Each of these products has a scenario where it makes sense. Here is an honest assessment of what that scenario is — and where each one falls short.
ConcenTrace (Trace Minerals)
The trace mineral specialist — not a hydration product
ConcenTrace has been around for over 50 years and has a legitimate claim as one of the best trace mineral supplements available. The ionic liquid format is the right approach, and the Great Salt Lake brine source is genuine. If your only goal is trace mineral supplementation and you already have your primary electrolytes covered elsewhere, it is a solid choice.
The limitation is by design: the manufacturing process removes 99% of sodium. This makes ConcenTrace excellent for trace minerals and essentially useless as a hydration or performance product. It cannot support fluid balance on its own. As a standalone electrolyte supplement for exercise or daily hydration, it falls well short. As a trace mineral top-up alongside a complete electrolyte source, it has a place.
Buoy
The right instinct — but the maths don't add up
Buoy has the right idea. Liquid format, ocean-sourced minerals, no sweeteners, convenient squeeze bottle. The concept is genuinely good. The problem is in the numbers.
Each serving is 1.5ml. Each bottle contains 60ml. Compare that to Seaonic's 10ml per sachet from a 300ml pack — five times the mineral volume per dose. At 50mg sodium and 10mg potassium per serving, Buoy is not delivering a meaningful electrolyte load for fluid balance. It functions more as a light trace mineral top-up than a complete supplement.
The "add to any drink" positioning also creates a real absorption issue. Adding minerals to coffee, tea, or hot drinks introduces compounds — tannins, oxalates, heat — that compete with or bind to minerals before the body can use them. Convenient in theory, counterproductive in practice.
LMNT
A pioneer in the space — but the category has moved on
LMNT deserves genuine credit. It was one of the first brands to break from the sugar-laden sports drink model and build a product around meaningful electrolyte ratios. For a while, it was the best available option in a market that badly needed it.
The category has since moved on. Citric acid appears in every flavoured SKU — it is there because it makes the product taste better, not because it supports your health. "Natural flavours" is a legally protected catch-all that can include hundreds of synthetic compounds. The 1000mg sodium load suits athletes with high sweat loss but is excessive for everyday use. And there are no trace minerals.
If you need flavour to get minerals down during hard training, LMNT is a reasonable choice. For daily mineral optimisation, it is the wrong tool.
Redmond Re-Lyte
Better ingredients, same category problem
Re-Lyte starts from a better place than most powder competitors. Redmond Real Salt is a genuinely mineral-rich, unrefined source, and the brand's commitment to clean sourcing is real. Magnesium malate and citrate are well-absorbed forms.
But the finished product still introduces citric acid, stevia, and coconut water powder — none of which are there for a biological reason. The citric acid is for taste. The stevia is for sweetness. The coconut water powder adds carbohydrates most users do not need. Since LMNT pioneered the cleaner powder format, dozens of brands have followed with similar formulas dressed up in different packaging. Re-Lyte is one of the better ones — but the fundamental limitation of the powder format remains. More ingredients than nutrients is always a signal worth paying attention to.
Liquid I.V.
A sports drink — and sometimes that is exactly what you need
Liquid I.V. is one of the most heavily marketed electrolyte products in the world, and the marketing is genuinely impressive. The formula is more straightforward than the branding suggests: 11g of cane sugar per serving makes it, by ingredient weight, closer to a sports drink than a mineral supplement.
That is not always a bad thing. Glucose genuinely aids sodium absorption in the gut — it is a well-established mechanism. In acute scenarios — recovering from illness, extreme heat, a long race — the sugar helps. For those moments, Liquid I.V. works.
For daily mineral support, it is the wrong product. The same effect can be achieved by pairing Seaonic with a piece of fruit or a small amount of natural carbohydrate — without the 11g of processed sugar per dose.
The bottom line
Each product in this review has a use case where it makes sense. ConcenTrace is an excellent trace mineral source if you have primary electrolytes covered. LMNT is a reasonable choice for athletes who need flavour to get minerals down during hard training. Liquid I.V. has a role in acute rehydration scenarios. Buoy has the right format instinct, even if the dosing does not follow through.
No other product in this review finishes in the top two across all four use cases. Seaonic comes closest to covering every base: complete primary electrolytes, complete trace minerals, ionic bioavailability, zero additives. Hypertonic for high-output periods, isotonic for everyday use. Suitable for everyone from children to elderly, from office workers to ultra-endurance athletes.
Sometimes less really is more. One ingredient. Every nutrient your body needs. Nothing it doesn't.
