Formulated with Purpose, Guided by Science
Cold Sore Guard™ is built around a targeted nutritional approach, using ingredients selected for their established roles in supporting immune balance, skin health, and lip comfort.
Each ingredient in the formula has been chosen for a specific purpose — not added for marketing appeal or unnecessary complexity. From essential amino acids and vitamins to plant extracts and absorption-supporting nutrients, every component plays a defined role within the overall formulation.
Rather than relying on single-ingredient solutions, our approach focuses on how nutrients work together to support the body from within as part of a consistent daily routine.
Explore each ingredient below to understand its role within the formula.
“When nutrition is built with care and backed by science, it supports your body the way it’s meant to be supported.”
The Science Behind Every Ingredient
Each ingredient in Cold Sore Guard™ is selected for a specific role in immune, skin, and lip support — backed by established nutritional science.
Tap each ingredient to learn why it was included and how it supports the formula
L Lysine
L-Lysine is an essential amino acid that plays a key role in protein synthesis and immune system function. It has been widely studied in relation to immune balance and skin health, particularly during periods of physical stress. Adequate L-lysine intake supports normal tissue repair and helps maintain healthy skin and lips.
Lemon Balm Extract
Traditionally used to support immune balance
Lemon balm is a botanical extract traditionally used to support the body during times of stress. It is known for its calming properties and has a long history of use in formulations focused on immune and skin support. Lemon balm also contains natural antioxidants that help protect cells from oxidative stress.
Zinc
Contributes to normal immune function and skin health
Zinc is an essential mineral that supports normal immune system function and contributes to the maintenance of normal skin. It also plays a role in normal protein synthesis and cell division, making it important for overall skin and tissue health.
Vitamin D3
Supports normal immune system function
Vitamin D contributes to the normal function of the immune system and plays a role in maintaining overall wellbeing. Adequate vitamin D levels are important for immune balance, especially during periods of limited sun exposure.
Vitamin B12
Supports energy metabolism and nervous system function
Vitamin B12 contributes to normal energy-yielding metabolism and supports the normal function of the nervous system. It also plays a role in reducing tiredness and fatigue, supporting overall wellbeing.
Vitamin K2 (MK-7)
Works synergistically with Vitamin D
Vitamin K2 supports normal bodily functions and works alongside vitamin D to help regulate normal physiological processes. This synergistic pairing is commonly used in modern nutritional formulations.
Magnesium
Supports muscle and nerve function
Magnesium contributes to normal muscle function, nerve signalling, and energy metabolism. It also plays a role in maintaining electrolyte balance and overall cellular health.
MCT Powder
Supports nutrient absorption and energy
MCT (medium-chain triglyceride) powder provides a clean, easily absorbed source of energy. It is commonly included in formulations to support nutrient absorption and overall metabolic efficiency.
Coenzyme Q10 (CoQ10)
Role in the body
Coenzyme Q10 is a naturally occurring compound involved in cellular energy production and antioxidant protection. It plays a role in maintaining cellular integrity, particularly in tissues with high energy demand.
Scientific research background
Coenzyme Q10 has been studied as part of combined nutraceutical formulations in the context of recurrent viral skin and mucosal infections, including herpes simplex virus. Research has focused on its role in regulating oxidative stress and supporting immune responses during viral challenges.

In this controlled clinical research, CoQ10 was evaluated as part of a multi-nutrient formulation used alongside standard antiviral therapy in individuals with recurrent herpes simplex infections. The study reported improvements in immune and oxidative stress markers and reduced viral DNA levels compared to control groups.
Important context
This study assessed a combination nutraceutical formulation used in conjunction with conventional antiviral therapy. It does not evaluate CoQ10 as a standalone treatment or oral supplement.
Why it’s included
CoQ10 is included in Cold Sore Guard™ to support cellular energy production and antioxidant balance, complementing other ingredients selected for immune and skin health support.
Food supplements are not intended to diagnose, treat, cure, or prevent disease.
Black Pepper Extract
Enhances nutrient absorption
Black pepper extract is included to enhance the bioavailability of key nutrients. It supports efficient absorption, helping the body make better use of the ingredients in the formula.
