Lysine: Lysine is an amino acid that can potentially help prevent cold sore outbreaks. It does so by blocking the replication of cold sores, which relies on the presence of another amino acid known as arginine.
Blackberry extract: Blackberries are rich in flavonoids, which are antioxidants that protect the body from free radical damage and have anti-inflammatory properties that can reduce swelling and redness around cold sores.
Vitamin C: Vitamin C is an antioxidant that protects cells from damage and boosts the immune system by increasing the production of white blood cells and antibodies to fight infections.
Astaxanthin: Astaxanthin possesses anti-inflammatory properties, which could make it a valuable supplement in the effort to decrease the inflammation often associated with cold sores. Through the reduction of inflammation, astaxanthin has the potential to ease discomfort and accelerate the healing progression.
Calcium lactate: Calcium lactate has demonstrated effectiveness in diminishing the duration of cold sores. Research published in the Journal of Oral Pathology and Medicine indicates that applying calcium lactate to the skin led to an average reduction of two days in the persistence of cold sores.
