About Clyra

Clyra's Chemistry and History of Iodine


The use of iodine as a disinfectant is nothing new, in fact iodine has been the most commonly used disinfectant in operating rooms globally for decades, and it’s first use as a medicine dates back to shortly after its discovery in the early 19th century.

As early as 1820, ordinary people kept small vials of iodine with them in case they needed it, not much different than the alcohol-based hand sanitizers of today, and by 1873 it started being used as a germicide. By 1902, it was recommended for pre-operative skin sterilization and iodine’s first use for wound care is believed to date back to the American Civil War.

Relevant to today’s world, there is also evidence that iodine was successfully used to help combat the Spanish Flu pandemic in 1918. More recently, iodine-containing solutions have been used to fight the spread of other respiratory viruses including the SARS epidemic in 2003 and MERS-CoV in 2015.


The path to the invention of the Clyra copper-iodine complex is not an uncommon one for our science team. It was born out of need and fueled by innovation to solve a common problem.

It began when our founding scientist needed to keep his father safe from infections associated with hospital and senior centers. His inventions to protect his father sparked a wave of innovation with a team of highly trained scientists that lead to the development of our copper-iodine complex that can easily and safely be applied to keep skin free from germs, virus, fungi and bacteria, reducing the likelihood for infections to occur. Our team leveraged the disinfecting power of iodine, in a safe, clear, and odorless formula that is the core of all Clyra products.

Helping keep people safe from infections is how Clyra, and the BioLargo Family of Companies, truly make life better.
