Yes. Cold Buster™ contains N-Acetyl Cysteine (NAC), which is known as a mucolytic. This means it breaks down mucus and phlegm and makes them easier to clear out of your chest and sinuses. By helping loosen thick secretions, NAC relieves congestion, promotes easier breathing, and supports overall respiratory recovery.
Unlike many mucolytic products that only contain NAC, Cold Buster™ also includes immune-supportive nutrients like Vitamin C, Zinc, and Glycine. It contains no Sucralose, Acesulfame K, or sodium benzoate—just clean, functional ingredients.

No. Cold Buster™ is non-sedative and caffeine-free. It supports your immune system and respiratory health without affecting focus, energy, or alertness.

No. Cold Buster™ does not contain artificial sweeteners like Sucralose or Acesulfame K, nor preservatives such as sodium benzoate—commonly found in many cold syrups. It’s sweetened and flavoured with clean, functional ingredients only.
Cold Buster™ should be taken as soon as possible at the first sign of illness—like a sore throat, blocked nose, or sinus pressure. Starting early helps clear mucus faster and supports your immune system before symptoms become more severe.

Immunity Is Foundational to Resilience
Kids are exposed to stress, germs, and high demands daily. A strong immune system helps them stay well, recover faster, and keep up with life.
Adolescents are constantly navigating immune challenges—from crowded classrooms and sports environments to disrupted sleep and fluctuating stress levels. Supporting the immune system during this developmental stage not only reduces sick days, but also helps teens maintain energy, focus, and emotional well-being through life’s daily demands.

What Weakens Immunity
Stress, nutrient gaps, poor sleep, and constant exposure can strain the immune system.
Between school pressure, sports, social stress, late nights, and screen time, today’s teens often push their bodies to the limit. These demands—combined with skipped meals or sugar-heavy diets—can leave their immune system undernourished and overworked. The result? More sick days, slower recovery, and less energy to engage fully with their day-to-day activities.

Immune Strength Starts with Daily Support
Key nutrients like Vitamin C, Zinc, and Glutamine are essential for immune health and recovery.
Research shows that immune strength depends on consistent nutritional support. Antioxidants like Vitamin C and NAC help protect cells from oxidative stress, while minerals like Zinc are essential for immune cell function. Amino acids like Glutamine and Glycine help the body recover faster. Fiber and Vitamin D also play a critical role in gut-immune balance and overall resilience—especially during growth, stress, or seasonal change.

What to Watch For
Frequent colds, fatigue, and slow recovery could be signs their immune system needs a boost
If your child seems to catch every bug going around, complains of feeling tired all the time, or takes longer to bounce back after illness or stress, it may be a sign their immune system is under pressure. These subtle signs are easy to overlook—but supporting immune health early can help your teen stay well, stay active, and stay focused.
