01Labeling, claims & marketingWebsite claims caused products to be unapproved new drugs marketed for disease treatment.
The claims on your website establish that the products Fucoidan, Prostate Health, Children Liquid Vitamins, and Immune Health are drugs under section 201 (g)(1)(B) of the Federal Food, Drug, and Cosmetic Act (the Act), [21 U.S.C 321(g)(1)(B)] because they are intended for use in the cure, mitigation, treatment, or prevention of disease.
02Labeling, claims & marketingProducts lacked FDA approval as new drugs for disease uses.
Your products are not generally recognized as safe and effective for the above referenced uses and, therefore, the products are “new drugs” under section 201(p) of the Act [21 U.S.C. § 321(p)]. With certain exceptions not applicable here, new drugs may not be legally introduced or delivered for introduction into interstate commerce without prior approval from FDA, as described in sections 301(d) and 505(a) of the Act [21 U.S.C. §§ 331(d), 355(a)].
03Labeling, claims & marketing · 21 CFR 201.5Products lacked adequate directions for layperson use, causing misbranding.
Your products Fucoidan, Prostate Health, Children Liquid Vitamins, and Immune Health are intended for treatment of one or more diseases that are not amenable to self-diagnosis or treatment without the supervision of a licensed practitioner. Therefore, it is impossible to write adequate directions for a layperson to use your products safely for their intended purposes. Accordingly, the Fucoidan, Prostate Health, Children Liquid Vitamins, and Immune Health products fail to bear adequate directions for their intended use and, therefore, the products are misbranded under section 502(f)(1) of the Act [21 U.S.C. § 352(f)(1)].
What FDA requested
- Provide specific steps taken to address the violations
- Provide explanation of each step being taken to prevent recurrence of violations
- Provide copies of related documentation
- If corrective actions cannot be completed within 15 working days, state the reason for the delay and the time within which you will do so
- If you believe products are not in violation, include reasoning and supporting information

42 paragraphs
21-HAFE4-WL-03 / CMS No. 613294 Dear Mr. Huynh:
This is to advise you that from October 2020 to March 2021, the United States Food and Drug Administration (FDA) reviewed your website at https://www.annahealth.com, and has determined that you take orders there for the products Fucoidan, Prostate Health, Children Liquid Vitamins, and Immune Health. In addition, we observed that the product Immune Health is intended to mitigate, prevent, treat, diagnose, or cure COVID-191 in people. The claims on your website establish that the products Fucoidan, Prostate Health, Children Liquid Vitamins, and Immune Health are drugs under section 201 (g)(1)(B) of the Federal Food, Drug, and Cosmetic Act (the Act), [21 U.S.C 321(g)(1)(B)] because they are intended for use in the cure, mitigation, treatment, or prevention of disease. As explained further below, introducing or delivering these products for introduction into interstate commerce for such uses violates the Act. You can find the Act and FDA regulations through links on FDA's homepage at www.fda.gov.
Examples of some of the website claims that provide evidence that your products are intended for use as drugs include:
On the website www.annahealth.com:
Fucoidan product:
“Fucoidan is a powerful anticancerous supplement from the Sea.”
“Fucoidan…triggers the natural immune system to attack and kill cancer cells.”
“Fucoidan suppresses the generation of new blood vessels around cancer cells, cutting off their nutrient supply. This also prevents the cancer cells from spreading.”
“Fucoidan provides an anticancer effect by way of inducing apoptosis.”
“Fucoidan reduces side effects of chemotherapy and radiation.”
Prostate Health product:
“Improves…urinary flow.”

Immune Health product:
“COVID-19 Influenza”

Your products are not generally recognized as safe and effective for the above referenced uses and, therefore, the products are “new drugs” under section 201(p) of the Act [21 U.S.C. § 321(p)]. With certain exceptions not applicable here, new drugs may not be legally introduced or delivered for introduction into interstate commerce without prior approval from FDA, as described in sections 301(d) and 505(a) of the Act [21 U.S.C. §§ 331(d), 355(a)]. FDA approves a new drug on the basis of scientific data and information demonstrating that the drug is safe and effective.
A drug is misbranded under section 502(f)(1) of the Act [21 U.S.C. § 352(f)(1)] if the drug fails to bear adequate directions for its intended use(s). “Adequate directions for use” means directions under which a layperson can use a drug safely and for the purposes for which it is intended (21 CFR 201.5). Prescription drugs, as defined in section 503(b)(1)(A) of the Act [21 U.S.C. § 353(b)(1)(A)], can only be used safely at the direction, and under the supervision, of a licensed practitioner.
Your products Fucoidan, Prostate Health, Children Liquid Vitamins, and Immune Health are intended for treatment of one or more diseases that are not amenable to self-diagnosis or treatment without the supervision of a licensed practitioner. Therefore, it is impossible to write adequate directions for a layperson to use your products safely for their intended purposes. Accordingly, the Fucoidan, Prostate Health, Children Liquid Vitamins, and Immune Health products fail to bear adequate directions for their intended use and, therefore, the products are misbranded under section 502(f)(1) of the Act [21 U.S.C. § 352(f)(1)]. The introduction or delivery for introduction into interstate commerce of these misbranded drugs violates section 301(a) of the Act [21 U.S.C. § 331(a)]. This letter is not intended to be an all-inclusive statement of violations that may exist in connection with your products. You are responsible for investigating and determining the causes of any violations and for preventing their recurrence or the occurrence of other violations. It is your responsibility to ensure that your firm complies with all requirements of federal law, including FDA regulations.
This letter notifies you of our concerns and provides you an opportunity to address them. Failure to adequately address this matter may result in legal action, including, without limitation, seizure and injunction.
Please notify FDA in writing, within 15 working days of receipt of this letter, of the specific steps you have taken to address any violations. Include an explanation of each step being taken to prevent the recurrence of violations, as well as copies of related documentation. If you cannot complete corrective actions within 15 working days, state the reason for the delay and the time within which you will do so. If you believe that your products are not in violation of the Act, include your reasoning and any supporting information for our consideration.
Your reply should be directed to Mr. Ramon A. Hernandez, District Director/Program Division Director, Food and Drug Administration, 466 Fernández Juncos Avenue, San Juan, Puerto Rico 00901-3223. If you have any questions regarding this letter, please contact LCDR Laura Kennedy, Compliance Officer, at (813) 915-7948 or Laura.Kennedy@fda.hhs.gov.
