I can help you with information about supplements that might support respiratory health, but it's important to note that a stopped-up nose can be a symptom of various conditions, and it's best to consult a healthcare professional for a diagnosis and treatment.

For respiratory health, some supplements that are often considered include:

• Vitamin C: Known for its immune-boosting properties, which might help with colds and congestion.
• Zinc: May help reduce the duration of cold symptoms.
• Eucalyptus Oil: Often used in steam inhalation to clear nasal congestion.
• Quercetin: A flavonoid that may have anti-inflammatory effects and support respiratory health.

If you're interested in specific supplement products for any of these, let me know, and I can help you find them.

Vitamin C is often considered one of the most effective supplements for supporting immune function, which can, in turn, help alleviate nasal congestion associated with colds and infections. Its efficacy derives from its antioxidant properties, antimicrobial and antiviral actions, and ability to enhance immune functions¹. However, the effectiveness of vitamin C supplements may vary depending on the individual's existing vitamin C levels and overall health status. Always consider consulting a healthcare professional before starting any supplementation, especially if you have underlying health conditions or are taking other medications.
