One ingredient: cold-microfiltered Atlantic seawater from phytoplankton vortexes in the Bay of Biscay, off the coast of France and Spain. It's purified and packaged, nothing added — a concentrated liquid that naturally contains up to 78 ionic minerals and trace elements.

Most electrolytes are a formulation — 8–12 isolated ingredients assembled to deliver just 3–4 minerals, often with sweeteners, flavours and fillers. Seaonic is one ingredient that's naturally rich in the full spectrum: up to 78 minerals and trace elements, nothing added. It's the difference between a fresh orange — one ingredient, naturally full of vitamins, minerals and nutrients — and boxed orange juice, a formulation of isolated ingredients with hardly any nutrition. Nobody built the orange; nature did.

Raw ocean water isn't — which is exactly the problem Seaonic set out to solve. It goes through multi-stage cold microfiltration in a European pharmaceutical-grade lab to remove contaminants, and every batch is third-party tested for heavy metals, microplastics and microbial safety before it's released. It's produced to food-grade standards under GMP and ISO certification.

Multi-stage cold microfiltration — no heat, no chemicals — all in one lab in Spain, with over 100 control parameters across the process. Every batch is third-party tested for microbes, chemical composition, heavy metals (lead, cadmium, mercury, arsenic) and microplastics, plus a full nutrient analysis to verify the mineral profile. COAs are available on request.

Both are the same seawater at different concentrations. Hypertonic (33 g/L) is natural seawater salinity, more concentrated than blood plasma. Isotonic (9 g/L) is diluted with spring water to match the mineral concentration of your blood plasma. Think of it like a bath versus an ice bath: a bath at body temperature helps bring you back to baseline, while an ice bath deliberately takes you outside your baseline to trigger a desired response. Same water — both have their place.

Hypertonic is the activating one — mornings, fasting, exercise. Isotonic is the gentle one — recovery, sleep, daily hydration. Many people use both at opposite ends of the day.

No. Zero carbs, zero sugar, zero sweeteners, zero flavours, zero additives. One ingredient — it breaks no protocol, whether that's carnivore, keto, fasting or paleo.

Tear. Drink. Take it neat, straight from the sachet. Don't mix it with water — it's a concentrated liquid, not a powder you dissolve.
