Real feedback

“I’ve been living with COPD for 8 years, and breathing used to feel like fighting a constant battle—shortness of breath even when walking slowly, and endless mucus that was hard to clear. Since I started using GFOUK® 3 months ago, the difference is incredible! It really cuts through the mucus effectively, and the inflammation in my lungs has calmed down a lot. Now I can take a 20-minute walk in the park without gasping for air. This natural plant-based formula is a lifesaver for people like me who hate relying on too many harsh meds!”——Michael R., 62, Florida

“Every fall and winter, my seasonal cough hits so hard that I can barely sleep through the night, and my throat always feels dry and irritated. I’ve tried countless remedies, but none worked as well as GFOUK®. The natural plant extracts don’t irritate my stomach at all, and after just 4 days of using it, my cough became less frequent. Last week, I even made it through a whole workweek without coughing during meetings! Its low-sugar, low-carb formula is also a big plus since I’m managing my blood sugar. Highly recommend it to anyone stuck with seasonal coughs!”——Sophia L., 34, New York

“As a former smoker, I’ve always worried about my lung health—I often felt tired and my chest felt heavy. A friend recommended GFOUK® to me for lung detox, and I’ve been using it daily for 6 months now. I can honestly say my breathing feels much fresher, and that dull chest pain is gone. What I love most is that it’s made with natural plant extracts, no weird chemicals. It’s become a staple in my daily health routine, and even my doctor commented that my lung function check results are better than last year. So glad I gave it a try!”——David T., 45, California

Expert Recommendation

During the development of GFOUK® NAC + Mullein Lung Detox Drops, we selected high-purity mullein extract. Each 60 ml bottle contains active compounds equivalent to 14 grams of fresh mullein leaf, concentrated through an advanced 50:1 supercritical extraction process.

This high-potency mullein essence allows the formula to penetrate deep into the airways, helping to clear accumulated mucus and toxins in the lungs, reduce respiratory inflammation, and support lung health at its root.

How does GFOUK® work?

The main component

GFOUK® NAC + Mullein Lung Detox Drops:
100% Natural Formula with 6 Powerful Lung-Supporting Ingredients

Mullein:
Specializes in expectorant and airway protection. It helps thin and loosen deep lung mucus, soothes airway inflammation, and promotes smoother breathing—widely known as a natural “lung cleanser.”

NAC (N-Acetylcysteine):
Targets deep lung detox and mucus dissolution. As a clinically recognized mucolytic ingredient, NAC breaks down and loosens thick, stubborn mucus accumulated in the lungs, enhances the respiratory system’s natural cleansing ability, and provides strong antioxidant protection—supporting long-term lung health from the root.

Sea Moss:
Focuses on respiratory hydration. Rich in natural gel-like compounds, it forms a protective moisture barrier in the airways, relieves dryness, and enhances breathing comfort.

Loquat Leaf:
Known for its anti-inflammatory and anti-irritation properties. It effectively defends the lungs from external pollutants, reduces airway sensitivity, and maintains a balanced lung microenvironment.

Ginger:
Offers strong anti-inflammatory and circulation-boosting effects. Its natural active compounds reduce lung inflammation, promote healthy blood flow, and improve overall respiratory function.

Lobelia:
Excels in airway dilation. It helps relieve bronchial spasms and improves breathing smoothness—especially beneficial for individuals experiencing shortness of breath or chest tightness.

Perfect for those seeking gentle yet potent lung care—no harsh additives, just pure herbal goodness to help you breathe easier, every day.
