What is Kelp?

Kelp is also known as the iodine-rich brown algae and found in the shallow oceans, absorbing minerals and nutrients from the water around it. Kelp is fast becoming one of the leading choices for consuming iodine, magnesium, calcium, potassium and iron. 

The natural source of nutrients and minerals also help aid nail and hair strength and growth. 

Why Physis Great British Sea Kelp?

As well as utilising the clean waters of Great Britain to avoid the pollutants which rob the supplement of the natural minerals and nutrients (so often affecting international supplements), we subscribe to ethical practices for the sustainability of our country's natural resources. Physis use local farmers who adhere to the strict regulations and only harvest by hand, using scissors for a lesser impact than mechanical harvesting methods which can have a lasting detrimental knock-on effect on the marine environment. 

Rest assured our premium price reflects the premium quality and Physis customers can have peace of mind that they are doing their bit to conserve our British marine life.
