Mucolytic that thins mucus; antioxidant that protects lung tissue

20 studies | 3,000 participants

500-1000mg daily (higher during illness)

Supports immune function; may reduce duration and severity of respiratory infections

30 studies | 10,000 participants
15-30mg daily; 75mg/day as lozenges during acute illness

Supports respiratory immune function; lozenges may reduce cold duration

15 studies | 2,000 participants
175-600mg elderberry extract daily during illness

Antiviral properties; may reduce duration and severity of respiratory infections

2-3g EPA+DHA daily

Anti-inflammatory effects support lung health; may help resolve respiratory inflammation

12 studies | 1,500 participants
500-1000mg daily

Flavonoid with antioxidant and anti-inflammatory properties; supports respiratory health

20 studies | 5,000 participants

How It Works

Respiratory health encompasses the function of your lungs, airways, and the immune defenses that protect them from infections and environmental insults. Good respiratory health means efficient oxygen exchange, clear airways, and robust defenses against pathogens. Common respiratory concerns include frequent colds and infections, chronic bronchitis, asthma, COPD, and environmental sensitivities.

CRITICAL: Respiratory symptoms like persistent cough, shortness of breath, wheezing, or chest tightness require medical evaluation. Conditions like asthma, COPD, and pneumonia need proper diagnosis and treatment. These supplements support respiratory health and immune function but do not replace medical treatment for respiratory diseases. If you have chronic respiratory disease, work with a pulmonologist and discuss any supplements to avoid interactions with medications.

* Vitamin D plays a crucial role in respiratory immune defenses. A large meta-analysis showed vitamin D supplementation reduces respiratory infections, especially in those who are deficient. Maintaining adequate levels supports lung immunity.

* N-Acetyl Cysteine (NAC) is a mucolytic that thins mucus, making it easier to clear from the airways. It's also an antioxidant that protects lung tissue. Meta-analyses support its use in chronic bronchitis and COPD.

* Vitamin C supports immune function and may reduce the duration and severity of respiratory infections. Regular supplementation is more effective than starting when already sick.

* Zinc is essential for immune function. Zinc lozenges taken at the start of a cold can reduce its duration.

* Elderberry has antiviral properties and meta-analyses show it can significantly reduce the duration and severity of upper respiratory infections.

* Omega-3 Fatty Acids have anti-inflammatory effects that support lung health. They help resolve inflammation and may benefit chronic respiratory conditions.

* Quercetin is a flavonoid with antioxidant and anti-inflammatory properties that supports respiratory health.

* Pelargonium Sidoides (African geranium) is effective for acute bronchitis based on Cochrane review evidence.

* Probiotics support the gut-immune axis and Cochrane review evidence shows they can reduce the incidence of acute upper respiratory infections.

Expected timeline: Vitamin D optimization: 2-3 months for full effect. NAC mucolytic effects: within days to weeks. Acute illness supplements (zinc, elderberry): most effective when started at first symptoms.

Type 2 Diabetes

Type 2 diabetes (T2D) is a disease in which blood glucose levels are too high. It is characterized by insulin resistance in muscle, fat, and pancreas cells and an inability of the pancreas to manufacture enough insulin to control blood glucose levels. T2D is strongly associated with excess body fat, and weight loss induced by lifestyle changes is extremely effective for treating T2D.

Multiple sclerosis is an autoimmune neurological disease characterized by the destruction of the myelin sheaths (nerve insulators) on neurons in the central nervous system. Its symptoms can vary, but eye pain, difficulty balancing, and numbness, tingling, and weakness in limbs are common. Attacks are “multiple” over time and/or location in the nervous system.
