The problem

Plain water passes through.
Minerals make it stay.

Most people are mildly dehydrated most of the time — not from lack of water, but from lack of the minerals that tell the body to hold onto it.

01
Water alone isn't enough

Without sodium present in the gut, water passes through without being fully retained at a cellular level. Your body needs the mineral signal to hold onto what you drink.

02
Sports drinks are sugar delivery

Most are primarily sugar with a token quantity of electrolytes. For daily hydration, the sugar load is unnecessary and the mineral content is minimal.

03
Daily life depletes you quietly

Caffeine, travel, training, reduced food intake. Modern life draws down your minerals in ways you don't notice — until you feel it.

Where it comes from

Three sources.
One ocean.

Every mineral in Element 01 has a name, a location, and a story. Nothing synthesised. Nothing anonymous.

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.

Scottish Sea Salt

West Coast sea water trickled through Scotland's only graduation thorn tower — facing the Isle of Arran — and evaporated by persistent coastal winds. No adding. No seeding. No bleaching.

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

Every session sweats out sodium, potassium, and magnesium. Element 01 replaces what you lose — cleanly, precisely, without the sugar that undoes the work.

  • Pre-session, intra, or recovery
  • Running, cycling, gym, team sport
  • Zero sugar — no empty calories

The Health-Conscious

When you eat less — through intention, appetite changes, or a structured programme — your mineral intake from food reduces too. Element 01 fills that gap cleanly.

  • Reduced appetite or food intake
  • Weight management programmes
  • Zero sugar · clean label · no fillers

The Everyday

Long days, frequent travel, caffeine, the occasional glass of wine. Two sachets a day replace what modern life quietly takes.

  • Daily mineral maintenance
  • Travel and long-haul recovery
  • Daily ritual — two sachets, 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.

Your ocean.
Every morning.

30 sachets per box. Two a day, each in 500ml of cold water. Less than the price of a coffee.

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 zero sugar, 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, zero-sugar 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. Two sachets per day, each dissolved in 500ml of cold water, is the recommended use. Element 01 contains 500mg 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.
