Why your body needs Magnesium

Magnesium is one of the body’s most important minerals — involved in over 300 essential processes including muscle function, recovery, relaxation and energy production.

Yet stress, sweating, exercise and daily life can all reduce your body’s mineral levels.

That’s why recovery starts with replenishment.

Sweat Depletes Minerals - When we sweat, we lose important minerals including magnesium, sodium and potassium.

Magnesium Supports Recovery - Magnesium helps support muscle relaxation, recovery and overall wellbeing.

Recovery Helps Performance - Your body performs better when it has time and support to recover properly.

Minerals Help Restore Balance - Minerals help replenish what movement, stress and modern life take away.

Mineral skincare - it’s a family passion

Sea Magik was born from a belief in the healing power of minerals. Founder Robert Czik was inspired by the transformative effects of natural salt while bathing in Hungary’s mineral-rich lakes, leading him to create the first mineral skincare range in 1981.

Now led by his daughter, Kate Bunyan, Sea Magik continues to harness the restorative power of sea minerals to bring healing results into everyday routines.

Our mission is simple: to make the skin and well-being benefits of mineral-rich skincare accessible to everyone, every day.

Mineral Science

Mineral science: ​Why your body needs minerals​

Humans are made of 70% water, containing essential minerals such as potassium, magnesium and sodium.​

​These minerals are crucial for optimal bodily functions, effective healing and overall skin health. ​

​Stress, poor diet and medication can deplete these mineral levels, leading to various skin conditions such as; acne, eczema and psoriasis, premature ageing, dandruff or itchy scalp, and even low mood or restless sleep.​
