High-Dose Vitamins Linked to Increased Lung Cancer Risk
Studies indicate an increased risk of lung cancer associated with high doses of vitamins, such as beta-carotene and B vitamins, especially for smokers and men. Experts caution against the indiscriminate use of supplements.
High-dose vitamins can elevate lung cancer risk. Medical professionals and consumer protection advocates are currently warning against a casual approach to dietary supplements. Smokers and former smokers are especially vulnerable.
These warnings are based on scientific studies and are reinforced by experts like Dr. Pieter cohen of Harvard Medical School. They contradict the widespread misconception that vitamins,as “natural” products,are always harmless.

Beta-carotene is a primary focus of the criticism. While beneficial in fruits and vegetables, it paradoxically acts differently in isolated, high doses, possibly becoming perilous for at-risk groups.
many individuals take dietary supplements without knowing their actual blood levels. This can be risky, especially with high-dose preparations.
