Filtered seawater, really?

One ingredient: cold-filtered Atlantic seawater, drawn from deep-ocean convergence zones off the Bay of Biscay. It carries up to 78 ionic minerals and trace elements in their natural balance — nothing added, no sugar, sweeteners, flavouring or fillers.

It is — which is exactly why every batch is purified and proven. The seawater is drawn from deep offshore, then cold-microfiltered down to 0.22 microns, finer than a bacterium, straining out microplastics, sediment and microbes. Dissolved contaminants like heavy metals are then verified within safe limits on a certificate of analysis for every batch — tested at extraction, after purification and after packaging, across 100+ control parameters. We don't ask you to trust that it's clean. We show you.

Restore (Isotonic) is the steady everyday option — any time of day, and most people reach for it before bed for sleep or after exercise for recovery. Activate (Hypertonic) runs stronger for a concentrated lift — mornings, before or during exercise, or periods of mental output. Most people keep both.

No — zero calories, zero carbs, zero sugar, nothing added. There's nothing in it to break a fast, knock you out of ketosis, or spike your blood sugar, insulin or dopamine. Whatever you're doing — fasting, keto, carnivore, elimination — Seaonic adds nothing to it.

Sea salt is what's left when seawater dries out — and the minerals don't leave together. As the water evaporates they precipitate at different rates, so sodium chloride crystallises out first and dominates, while the trace minerals get locked into the crust as oxides and silicates your body can't readily use. You end up with concentrated salt and only a fraction of the spectrum. Seaonic never dries out — it stays liquid, so every mineral stays dissolved, ionic, and in its natural balance. The whole spectrum, not just the salt.

A powder isolates three to five minerals, dries them into salts, and adds flavour and stabilisers to make them usable. A multivitamin adds synthetic isolates. Seaonic is neither — it's the ocean's full mineral spectrum, already ionic, one ingredient, nothing added.

Salty — as minerals should be. There are no sweeteners or flavours to mask it, so you taste clean, mineral seawater and nothing else.

You can, but it defeats the point. Seaonic is sealed at a precise concentration, and concentration is what drives absorption — dilute it into a random amount of coffee or juice and you change that. Take it straight, or in a little water. Any brand telling you to mix it into whatever you like isn't really thinking about absorption.

Every batch is tested three times — at extraction, after purification, after packaging — across 100+ control parameters, in a GMP- and ISO-certified European facility. Each batch carries a certificate of analysis verifying heavy metals and contaminants within safe limits.

Two strengths, two moments. Reach for Hypertonic (Activate) in the morning, before or during exercise, or through periods of mental output — just avoid it right before bed. Isotonic (Restore) works any time of day; most people use it before bed for sleep, or after exercise for recovery.

Because of what it takes to make it this clean. Most electrolytes are a formula sent to a contract manufacturer that sources the cheapest ingredients it can find. Seaonic is one ocean-sourced ingredient, made and tested in a single European pharmaceutical-grade facility, with a certificate of analysis on every batch. You're paying for what isn't in it — and for being able to prove it.
