為何選擇海洋深層水

深度為何重要

海洋深層水一般指 200 公尺以下、陽光難以有效到達的海水。環境低溫且穩定，受短期表層波動影響較小。

0 公尺海面
0–200 公尺表層水

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
