Seaweed fabric releases marine amino acids, minerals and vitamins into the skin upon contact with moisture

Lululemon Athletica has been a standout performer on Wall Street since it went public in July, thanks to the popularity of its costly yoga and other workout clothes, which are made with unusual materials, including bamboo, silver, charcoal, coconut and soybeans.

The label on a shirt at Lululemon says it contains seaweed.

One of its lines is called VitaSea, and the company says it is made with seaweed. The fabric, according to product tags, “releases marine amino acids, minerals and vitamins into the skin upon contact with moisture.” Lululemon, which has received positive media coverage for its fabrics, also says the VitaSea clothing, made from seaweed fiber supplied by a company called SeaCell, reduces stress and provides anti-inflammatory, antibacterial, hydrating and detoxifying benefits.

There is one problem with its VitaSea claims, however. Some of them may not be true.

The New York Times commissioned a laboratory test of a Lululemon shirt made of VitaSea, and reviewed a similar test performed at another lab, and both came to the same conclusion: there was no significant difference in mineral levels between the VitaSea fabric and cotton T-shirts.

In other words, the labs found no evidence of seaweed in the Lululemon clothing.
