FAQs

General FAQs

Q: What are the benefits of dietary supplements?

There are many reasons to consider dietary supplements as a complement to health care. While a good diet is the foundation for better health, research shows that most people don't eat the way that they should. Supplements are easy to add to the daily diet, and this is often the first step that people take toward greater nutritional awareness and the adoption of other healthy lifestyle choices. Whether taking a multivitamin, herb or specialty product, people can and do live healthier lives by supplementing their diets.

Q: Is Lung+Liver Defense safe to take?

Lung+Liver Defense is manufactured in the USA at an FDA registered facility. Lung+Liver Defense is held to FDA Good Manufacturing Practices (GMP) that ensures product safety is always the number one priority for every softgel produced.

Q: What are the beneficial ingredients in Lung+Liver Defense for liver health support?

Milk Thistle has been clinically proven to help aiding the liver in detoxifying various contaminants and help healing damages in the liver by promoting the generation of new liver cells. Silymarin is the main active component in milk thistle and a well-known hepatoprotective agent. The content of the components is at least 80%. It may exert its hepatoprotective activity through antiviral, anti-inflammatory, antioxidant actions in the liver.

Q: What are the beneficial ingredients in Lung+Liver Defense for respiratory health support?

Both eucalyptus and oregano are excellent expectorants which may aid the respiratory system to detoxify the breathed contaminants. 1,8-Cineole is the main active component for eucalyptus and carvacrol for oregano. The contents of the main active components are at least 80% for eucalyptus and 60% for oregano. These active components may provide multiple therapeutic effects such as antioxidant, antimicrobial, and antifungal properties.

Q: How can I know if the supplement I bought has the ingredients listed on the label?

The U.S. Food and Drug Administration doesn’t analyze the content of dietary supplements; therefore, you are relying on the manufacturer to be truthful when you purchase one of our products. The FDA has issued Good Manufacturing Practices for supplements, which specify rules for the products’ identity, purity, strength and composition.

Q: Where can I find reliable information on supplements?

A good place to start is the website at the Office of Dietary Supplements, National Institutes of Health, which has fact sheets on many supplements (https://ods.od.nih.gov/factsheets/list-all/). The site also has a lot of general information about supplements.

Q: Should I check with my physician or healthcare provider before taking a dietary supplement? 

If you are pregnant, nursing a baby, or have a chronic medical condition, such as, diabetes, hypertension or heart disease, you should check with your physician, healthcare provider or pharmacist before purchasing or taking any supplement. Keep in mind that the ingredients in dietary supplements are not tested or approved by the FDA. For more information on this or the FDA's role in Dietary Supplement Regulation please visit the Question and Answer section of the FDA's Web site.

Q: How do environmental contaminants affect our health?

It is known that air pollution causes 7 million deaths and contaminated foods and drinks cause 1.5 million deaths a year worldwide. The air pollutants including toxic gases and particulate matters (PMs) are byproducts of rapid industrialization. The contaminated foods and drinks are byproducts of poor sanitation more common in developing countries. The air pollutants and the contaminated foods or drinks are the environmental contaminants and can cause serious respiratory, cardiovascular and liver diseases, and it could lead even to deaths by being exposed without protection for long time.

Q: What are the negative health affects of particulate matter?

Particulate matter (PM) is a complex mixture of airborne particles that differ in size, origin and chemical composition, all of which are <10 μm in size. Particulate matter causes health effects upon inhalation. The severeness of health effects is determined by size, composition and concentration. Exposure may cause heart and lung disease, and may worsen acute and chronic bronchitis and asthma. The risk of health effects is larger for certain groups of individuals, such as CARA patients, elderly people with respiratory defects, young children and people that do heavy physical labor. High levels of particulate matter may not only affect these groups of people; this causes the entire population to be at risk.

Q: How does Lung + Liver Defense Herbal supplement protect me from environment contaminants?

In our body, the lung provides the first line of protection by neutralizing and expelling the air pollutants. The liver also provides the protection from the ingested food and drink contaminants. Eucalyptus/Oregano oil are excellent expectorants which aid the respiratory system to detoxify the breathed contaminants. Milk thistle can aid the liver in detoxifying various contaminants and heal damages in the liver by promoting the generation of new liver cells. Therefore, we believe that the most effective way to fight against the environmental contaminants is maintaining the health of the respiratory system including the lung and the liver.

Q: How long can I take Lung + Liver Defense? / Will it build up tolerance after extended period of time/usage?

If there is no adverse effect while taking the Lung+Liver Defense, you can keep using the product when you need a protection from the environmental contaminants. The extended usage will not build up the tolerance.

Q: From what age, Lung + Liver Defense is safe to take?

Three ingredients are the substances designated by American Food and Drug Administration (FDA) as Generally Recognized As Safe (GRAS) and are considered safe by experts. Defining the age as a safe guideline is not possible due to individual variations of weight, genetic, or health condition. Generally it is not recommended for infants and young children.
