In health food, the blue hat is a passport, which symbolizes quality. Regular health food will be marked with sky blue on the product packaging, such as the "hat" sign, and the health food approval number will be marked below.
Blue hat products refer to health food approved by the US Food and Drug Administration. Health products need SC certification, national policy approval, health food approval or blue hat certification.
Extended data:
1. All official health foods in China, whether imported or made in China, must be marked "police tactical unit" on the packaging.
2, health food packaging and advertising should be marked with the slogan "this product can not replace drugs".
3. If there are "taboo words" such as "ancestral secret recipe", "safety", "no toxic side effect" and "the highest science" on the packaging of health food, it may be a fake and shoddy product.
4. If you have any questions about purchasing health food, you can log on to the website of American Food and Drug Administration to check "police tactical unit" and "American Food and Drug Administration" to confirm whether the purchased products are fake or not.
