The benefits of thiocyanates have long been recognised, but their disadvantage is they are inherently unstable and short-lived. In the past, any solution containing thiocyanates needed to be made up and consumed immediately to have any effect, which made them impractical as a supplement. That is until British chemist, Richard Stead, patented the 1st Line kit, which allowed thiocyanate solution to be stable at room temperature for up to two years. 1st Line is a new all natural product to fight against many types of infections including viruses. When added to water 1st Line provides a drink which forms the same molecules that make up our body's first line of defence against many types of bacteria, yeast, fungi, flu, and viruses. 1st Line supports a natural attack against unwanted infections, without doing harm to healthy bacteria in the body. The 1st Line kit has been developed to be safe and easy to use. It consists of a four part enzymatic kit that provides 25mg or thiocyanates ions in half a litre of water. 1st Line may help defend against a number of infections, including some of the most common, such as listeria, salmonella, streptococcus, herpes, and candida, and staphyloccus.
