Best Respiratory Supplements

Have you or someone you know been suffering from chronic, nagging asthma that refuses to go away? While inhalers quickly relieve the chest tightness by opening up the lung’s airways with stimulants, it may cause unpleasant side effects. Respiratory supplements however, can improve overall lung health and function naturally.

Good respiratory health provides our blood cells, tissues and organs with optimal oxygen intake, and is crucial for our very survival. Although a balanced diet, regular exercise, a healthy lifestyle and proper medical care all play vital roles in respiratory health, certain dietary supplements can provide additional support and maximize all of our efforts.

For instance, if you’ve decided to stop smoking and finally quit it for good, these supplements can reduce inflammation, make it easier to breathe and help your lungs heal from all the damage inflicted on it from months or years of smoking. Or there may be something in your home or working environment causing an allergic reaction and histamine release, leading to stuffy sinuses and making it harder to breathe properly. Whatever the case, these supplements can be super helpful. They are often available in different formulations, including capsules, liquids, powders, and extracts.

Listed below are some of the best respiratory supplements that have shown promise in promoting good lung health, along with their various additional benefits.


Vitamin C

Also known as ascorbic acid, is a powerful antioxidant that supports lung health. It helps combat oxidative stress caused by pollutants and toxins, reducing the risk of respiratory ailments. Vitamin C also plays a crucial role in immune health and collagen synthesis, contributing to the strength and elasticity of lung tissues.

Foods rich in vitamin C include citrus fruits, berries, kiwi, broccoli, and red bell peppers. Supplementing with vitamin C can be beneficial for individuals who don’t eat these foods, those with respiratory conditions, or those at risk of developing them.

Vitamin D

This vitamin is primarily known for its role in immune and bone health, but emerging evidence suggests that it also plays a significant role in respiratory health as well. Research has strongly linked vitamin D deficiency to an increased risk of respiratory infections and asthma attacks. Adequate vitamin D levels are crucial for maintaining a healthy immune system and reducing inflammation in the respiratory tract.

Natural sources of this vitamin are scarce in food, but the most concentrated source can be extracted from adequate sunlight exposure. Unfortunately, many people don’t eat enough fatty fish or are unable to spend sufficient time in the sun every day, leading to a deficiency and a host of health problems. Therefore, taking D supplements is essential.

Omega-3 Fatty Acids

These nutrients, particularly eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), are quite beneficial for respiratory health. These essential fatty acids have anti-inflammatory properties that can help reduce airway inflammation and improve lung function. Studies have suggested that omega-3 supplementation can be beneficial for individuals with respiratory conditions like asthma.

Omega-3s can be found in fatty fish like salmon, tuna, mackerel, and sardines, as well as in flaxseeds, algae, chia seeds, and walnuts. Supplementation with high-quality fish oil or algae oil can provide a concentrated dose of omega-3s for individuals who do not consume enough through their diet.

N-Acetylcysteine (NAC)

NAC is a potent antioxidant and mucolytic agent that supports respiratory health. It helps break down and thin out lung mucus, making it easier to clear from the airways and potentially reducing the risk of respiratory tract infections. It has shown promise in managing respiratory conditions such as chronic obstructive pulmonary disease (COPD) and bronchitis. Additionally, it has been used as an adjuvant therapy for cystic fibrosis, asthma, and respiratory infections. NAC is available as an OTC dietary supplement, but it is advised to take it under medical supervision.


This is a flavonoid with antioxidant and anti-inflammatory properties. It has been studied for its potential benefits in reducing joint pain and improving respiratory health due to its ability to inhibit histamine release (a chemical involved in allergic responses) and reduce airway restriction.

This wonder substance has also been shown to alleviate symptoms of allergies, asthma, and respiratory infections, thanks to its natural anti-histamine effect on the body. It is naturally found in foods such as onions, apples, berries, and green tea. Taking quercetin supplements can provide higher doses for therapeutic purposes, but it is best to only take it when needed, as excessive amounts can lead to stomach upset and other unpleasant side effects.


This herbal remedy has been used for centuries in traditional Asian medicine. In particular, Korean red ginseng has been used for its respiratory health benefits. It is believed to possess anti-inflammatory, immunomodulatory, and antioxidant properties that can support lung function and enhance overall respiratory health. Ginseng has also shown potential in improving symptoms of chronic respiratory conditions such as asthma and COPD.


This mineral is involved in numerous biochemical reactions in the body, including those related to lung function. It helps relax bronchial smooth muscles, promoting easier breathing and reducing bronchospasms. Individuals with asthma may benefit from magnesium supplementation, as studies have shown potential improvements in lung function and reduced asthma symptoms.

Final Thoughts

While respiratory supplements can provide additional support for lung health, it is important to note that they are not a substitute for a healthy lifestyle and proper medical care. Please note that before starting any new supplements, it is strongly advised to consult with a healthcare professional, especially if you have an existing respiratory condition or are taking medications.

Additionally, if you’re a coffee or green tea lover, it’s best to wait on it for at least an hour before or after your meal and supplements. This is because caffeine binds with several vitamins and minerals, reducing your body’s ability to absorb them.
