为何选择海洋深层水

深度为何重要

海洋深层水一般指 200 公尺以下、阳光难以有效到达的海水。环境低温且稳定，受短期表层波动影响较小。

Deep Sea Water Benefits

Natural minerals and trace elements

Deep sea water contains a rich spectrum of naturally occurring minerals and trace elements.

These ocean electrolytes are formed over thousands of years through natural processes and remain in balance in the deep ocean, far from surface pollution.

The value lies in nature’s balance. Unchanged. Unprocessed. Naturally balanced.

1 liter of seawater (simplified)

Water (H₂O)96.5%(965 g)
Minerals3.5%(35 g)

Mineral distribution (approx.)

Chloride (Cl⁻)55.0%(19.3 g)
Sodium (Na⁺)30.6%(10.7 g)
Magnesium (Mg²⁺)3.7%(1.3 g)
Sulfate (SO₄²⁻)7.7%(2.7 g)
Calcium (Ca²⁺)1.2%(0.42 g)
Potassium (K⁺)1.1%(0.39 g)
Other constituents 0.7%(0.25 g)

Naturally occurring ocean electrolytes

  • Magnesium

    Supports natural mineral balance

  • Calcium

    Found in stable, natural ratios

  • Potassium

    Essential ocean electrolyte

  • Sodium

    Primary electrolyte in seawater

  • Chloride

    Most abundant anion

  • Sulfate / Bicarbonate

    Important oxygen-carrying anion in seawater

Trace minerals & elements

Deep sea water contains a wide spectrum of naturally occurring trace components. These are present in tiny amounts but reflect the ocean’s rich mineral environment.

  • BBoronNaturally occurring trace element
  • ZnZincNaturally occurring trace element
  • IIodineNaturally occurring trace element
  • CuCopperNaturally occurring trace element
  • MnManganeseNaturally occurring trace element

Many more trace elements are present in naturally occurring, ultra-low concentrations.

Naturally balanced by the ocean

Formed Over Time

Minerals and trace elements are dissolved through natural oceanic processes over thousands of years.

Stable & Consistent

Deep ocean conditions help maintain a consistent and stable mineral profile.

Unchanged by Humans

Collected from below the surface, far from surface pollution and seasonal variability.
