Calcium spirulan may help cold sores
Calcium spirulan derived from Spirulina platensis inhibits herpes simplex virus 1 attachment to human keratinocytes and protects against herpes labialis.
Study highlights combination treatments
We investigated the potential of calcium spirulan, a compound derived from the microalga Spirulina platensis, to help prevent cold sores caused by the herpes simplex virus type 1 (HSV-1). In a thorough study, we assessed the effectiveness of this sulfated polysaccharide both in laboratory tests and through a practical trial involving people with recurring herpes labialis, also known as cold sores.
Our approach included examining how calcium spirulan affected the virus’s ability to attach to human skin cells. Using various experiments such as plaque reduction assays and analyzing viral proteins, we confirmed that calcium spirulan had significant inhibitory effects on HSV-1. In the practical trial, we compared the effects of topical calcium spirulan treatment against other commonly used antiviral medications among 198 participants, all of whom dealt with repeat cold sore outbreaks.
The results suggest that calcium spirulan could be a valuable option for topical treatment, offering new hope for those who suffer from cold sores. Additionally, our findings indicate that calcium spirulan may also show effectiveness against other herpesviruses. This points to the broader clinical implications of using natural compounds like calcium spirulan in managing viral infections.

Sensitive enamel restored
Proven effective! I took this product to reduce the sensitivity of my enamel, and within a month everything returned to normal; I can now safely eat hot or cold food. There was no need for fluoridation of my teeth. Overall, I highly recommend it.

Quick pain relief
In under a week, my tooth sensitivity vanished completely. I experienced pain with everything—sour, sweet, cold. The dentist advised calcium, which led me to choose hydroxyapatite due to its low acidity. It caused no discomfort, and I will definitely repurchase.

Diminished sensitivity
This product is the primary ingredient in my tooth remineralisation powder. In just under two weeks, my tooth sensitivity has reduced by at least 50%. I can now manage cold items better and have not yet attempted ice cream. I'm a fan of Now products and would highly recommend them.
