Marine Electrolytes — Element 01

Most electrolytes
are made in a lab.
Ours is made by the ocean.

Every mineral in the sachet comes from a named stretch of Atlantic water — salt from the Irish coast, magnesium from seawater, calcium from red algae. Stir one into cold water each morning. That’s the whole routine.

The problem

Plain water passes through.
Minerals make it stay.

You can drink water all day and still feel flat. Without minerals, most of it passes straight through you.

01
Water alone isn't enough

Sodium is what tells your body to keep the water you drink. Skip it and much of that pint just visits.

02
Sports drinks are sugar delivery

Read the label on most of them: sugar first, minerals somewhere near the bottom. Fine for a marathon. Odd for a Tuesday.

03
Daily life depletes you quietly

Coffee, flights, training, eating less than you used to. The drain is slow enough that you blame tiredness on everything else first.

Where it comes from

Three sources.
One ocean.

We can point at the stretch of coast every mineral came from. The salt in most “natural” electrolytes was mined out of a mountain; ours was drawn from the sea and dried, and that’s about all that happens to it.

Atlantic Ireland
Marine Calcium
from Seaweed

Lithothamnion red algae — calcified seaweed from the pristine Irish Atlantic — naturally concentrates calcium and 72 trace ocean minerals in the ratios the sea assembled over millennia.

Kiln-Dried
Mineral Sea Salt · PDO

Drawn from the Irish Sea through a sealed, pressurised system — crystallised underwater, never touching air — then kiln-dried into a crystal-white mineral salt. Protected by EU designation of origin. Never mined. Nothing added. Nothing bleached.

Marine Magnesium
from Irish Sea Water

Drawn from seawater off the Irish coast and concentrated gently, keeping the mineral profile the sea gave it. This is the magnesium your muscles actually ask for at the end of a long day.

Ocean trace minerals per sachet

Boron, chromium, copper, iodine, iron, manganese, selenium, zinc and dozens more — arriving together, in the natural balance the ocean assembled them. No laboratory process can recreate this.

Not just the gym

The gym got us here.
Daily life keeps us here.

Sweat is only one way the body loses minerals. Reduced food intake, travel, caffeine, and the quiet demands of daily life deplete you just as steadily.

The Active

You sweat out more than water in a session. This puts the minerals back without handing you a sugar drink to undo the effort.

  • Pre-session, intra, or recovery
  • Running, cycling, gym, team sport
  • Under 5 kcal — no empty calories

The Health-Conscious

Eating less also means fewer minerals arriving with your food. A sachet quietly covers the gap while you get on with it.

  • Reduced appetite or food intake
  • Weight management programmes
  • Clean label · no fillers · nothing artificial

The Everyday

Long days, airports, coffee, the odd glass of wine. One sachet puts back what the week takes out.

  • Daily mineral maintenance
  • Travel and long-haul recovery
  • Daily ritual — one sachet, 30 seconds

Element 01 is a food supplement. It is not a medicine and does not treat or prevent any medical condition. If you are on prescribed medication or a medically supervised programme, consult your healthcare provider before use.

Questions

The science,
plainly put.

Everything worth knowing about why ocean minerals work — and why it matters where yours come from.

Sodium is an electrolyte — a mineral that carries an electrical charge in water — essential for how your body manages fluid. When sodium is present in your gut, it actively draws water across the intestinal wall into your bloodstream through osmosis. Without it, water passes through without being fully retained at a cellular level.

This is why plain water after heavy exercise or a long flight often doesn't fully rehydrate you. Your body needs the right mineral signal to hold onto the water you drink. Sodium is that signal.

Most sports drinks are primarily a sugar delivery system with a small amount of added electrolytes. For daily hydration, the sugar load is unnecessary and the mineral content is minimal.

Element 01 is under 5 kcal per sachet and built entirely from named ocean mineral sources. The focus is on the minerals themselves — not on making water taste sweet enough to drink more of it.

The 72 trace minerals come from Lithothamnion red algae — calcified seaweed from the Irish Atlantic coast. Over its lifetime, this algae absorbs minerals directly from the surrounding ocean, concentrating them in the same ratios the sea holds them.

They include boron, chromium, copper, iodine, iron, manganese, molybdenum, selenium, silicon, strontium, vanadium, zinc, and dozens more — arriving together, in natural balance, as the ocean assembled them.

Yes. When food intake reduces — through intentional calorie reduction, appetite changes, or a structured health programme — your intake of minerals from food naturally reduces too.

Element 01 provides a clean source of key electrolytes and 72+ ocean trace minerals to support everyday mineral intake. Always consult your healthcare provider if you are on a medically supervised programme or prescribed medication.

Yes. One sachet per day, dissolved in 300–500ml of cold water, is the recommended use. Element 01 contains 450mg of sodium per sachet — consistent with guidance for healthy adults. Not suitable for children or as a substitute for a varied diet.

Unopened boxes can be returned within 30 days. Subscriptions can be cancelled, paused, or skipped at any time from your account — there's no minimum commitment and no cancellation fee.
