There are several reasons for banning astaxanthin in the United States. Astaxanthin is a natural pigment commonly found in certain marine organisms, especially shrimp and crabs. It is widely used in food and cosmetics as a colorant and antioxidant. The U.S. Food and Drug Administration (FDA) believes that the safety of astaxanthin has not been fully proven. While some research has been conducted, there is still controversy regarding the effects and potential risks of long-term astaxanthin intake.

Astaxanthin may cause allergic reactions in some people. Some people may be allergic to astaxanthin, causing itchy skin, difficulty breathing and other uncomfortable symptoms. In order to protect the safety and health of consumers, the United States prohibits food and cosmetics containing astaxanthin from being placed on the market.

The ban on astaxanthin in the United States is also related to some environmental factors. The extraction of astaxanthin from marine organisms requires extensive fishing and processing. This may cause irreversible effects on marine ecosystems and destroy the ecological balance of marine life. In order to protect the marine environment and sustainable development, the United States may choose to ban the use of astaxanthin.

It should be pointed out that different countries have different standards and regulations for the use of astaxanthin. Although astaxanthin is banned in the United States, some other countries still allow its use and consider it safe and effective. Therefore, when purchasing products containing astaxanthin, consumers should pay attention to the ingredient information on the product label and follow local regulations and recommendations.

The ban on astaxanthin in the United States is mainly based on concerns about its safety and potential risks, including a lack of sufficient evidence and the possibility of causing allergic reactions. Also related to environmental protection and sustainable development. Although astaxanthin is banned from the U.S. market, it is still available in other countries and is widely used in food and cosmetics. Consumers should choose carefully when purchasing and follow local regulations and recommendations.
