A trusted, over the counter cold sore fighter

Tired of ineffective cold sore home remedies? In certain individuals, high Lysine blood levels may help prevent the Cold Sore virus from replicating, while reducing the duration and severity of outbreaks.*

L-Lysine is an essential amino acid that is needed daily for proper protein growth. In high levels it supports specific areas of the body responsible for decreasing frequency and severity of outbreaks that occur on the mouth and/or genitals.* Ingredients: L-Lysine (500mg), capsule (vegetable source), cellulose, magnesium stearate (vegetable source) *These statements have not been evaluated by the Food and Drug Administration.

Cold Sores, or HSV-1, are caused by the Herpes Simplex Virus, which is known to hide in the spine. During times of stress or when the immune system is compromised, the herpes virus may cause an outbreak, resulting in one or more cold sores. Cold sores cause mild discomfort to severe physical pain. While few over the counter herpes treatments work, Lysine (especially as a combination therapy) has been linked to a reduction in Cold Sore symptoms.

What is L-lysine?

L-Lysine is an essential amino acid that is needed daily for proper protein growth.

Does daily L-lysine work in preventing outbreaks?

L-lysine is believed to work by blocking the amino acid (arginine) that is responsible for multiplying the herpes virus. When used consistently, L-lysine will block arginine and can prevent outbreaks from forming.

Is L-lysine a prescription medication?

No, L-lysine does not require a prescription and can be used as an all-natural way to prevent herpes outbreaks.

Why is L-lysine only available for delivery?

Our L-lysine is compounded in our specialty pharmacy and not available at local pharmacies. Once your order is processed, your package will leave our pharmacy within 24 hours and arrive at your doorstep in 3-5 days.

How do I know wisp is legitimate?

You can check our LegitScript certification at the bottom of our site (a 3rd party accreditation service that Google uses and requires in order to advertise prescription drugs). All of our physicians and partner pharmacies are U.S. licensed & Board Certified (they can only dispense medication from certified manufacturers). Plus, we store all of your data in a HIPAA compliant manner, and ensure that our payment processing is PCI compliant.

Cold sores are common. But outbreaks decrease in intensity and duration with antiviral medication. We prescribe FDA approved meds based on the frequency and severity of symptoms.
