Penn Herb Wellness Guide
Lung Cancer Prevention
- Reliable and relatively consistent scientific data showing a substantial health benefit.
- Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
- For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.
Our proprietary “Star-Rating” system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by some in the medical community, and whether studies have found them to be effective for other people.
For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.
| Supplement | Amount | Why |
|---|---|---|
Beta-Carotene | Refer to label instructions |  [3 stars] Beta-carotene supplementation appears to reduce cancer risk in nonsmokers. Smokers should avoid beta-carotene supplements, including the amounts found in multivitamins. |
Selenium | 200 mcg daily |  [2 stars] Selenium, reported to have diverse anticancer actions, has been shown in one study to reduce lung cancer incidence. |
Vitamin E | 200 to 400 IU daily | [2 stars] High vitamin E levels have been associated with a reduced lung cancer risk. In one trial, nonsmokers who took vitamin E had a 45% lower lung cancer risk compared with those who did not take the vitamin. |
Conjugated Linoleic Acid | Refer to label instructions |  [1 star] Preliminary research suggests that CLA might reduce the risk of cancers at several sites, including breast, prostate, colorectal, lung, skin, and stomach. |
Folic Acid | Refer to label instructions | [1 star] Together, folic acid and vitamin B12 help cells replicate normally. In one trial, smokers with precancerous lung changes who were given folic acid and vitamin B12 saw a significant reversal of their condition. |
Green Tea | Refer to label instructions | [1 star] Numerous preliminary studies have shown an association between drinking green tea and a reduced risk of several types of cancer including lung cancer. |
Vitamin B12 | Refer to label instructions | [1 star] Together, folic acid and vitamin B12 help cells replicate normally. In one trial, smokers with precancerous lung changes who were given folic acid and vitamin B12 saw a significant reversal of their condition. |
