01OtherThe product is a food with added tadalafil, a drug approved under section 505, making its introduction into interstate commerce a prohibited act under section 301(ll).
Your Vital Honey product is a food to which tadalafil has been added. Therefore, the introduction or delivery for introduction into interstate commerce of this product is a prohibited act under section 301(II) of the FD&C Act.
02Labeling, claims & marketingThe product is an unapproved new drug because website claims show it is intended to cure, mitigate, treat, or prevent disease, and it is not generally recognized as safe and effective.
Your Vital Honey is not generally recognized as safe and effective for the above-referenced uses and, therefore, the product is a “new drug” under section 201(p) of the FD&C 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 & marketingThe product is misbranded because it lacks adequate directions for lay use, as it is intended for diseases requiring practitioner supervision.
Your product Vital Honey is 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 product safely for its intended purposes. Accordingly, Vital Honey fails to bear adequate directions for its intended use and, therefore, the product is 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, including an explanation of each step to prevent recurrence and copies of related documentation.
- If corrective actions cannot be completed within 15 working days, state the reason for delay and the time within which they will be done.
- If you believe products are not in violation, include reasoning and supporting information.

1Introduction
1 paragraph
This letter is to advise you that the U.S. Food and Drug Administration (FDA) obtained a sample of your product Dose Vital Royal Honey VIP Honey (Vital Honey) purchased directly from your website at www.wholesaleonline1.com. FDA also reviewed your website in June 2022. Based on our review of your website and laboratory analysis of your product, FDA has identified serious violations of the Federal Food, Drug, and Cosmetic Act (FD&C Act).
2Prohibited Act under Section 301(ll)
3 paragraphs
FDA confirmed through laboratory analysis that a sample of your Vital Honey contains the undeclared active pharmaceutical ingredient tadalafil, which is a phosphodiesterase type-5 (PDE-5) inhibitor. Tadalafil is the active ingredient in the FDA-approved prescription drug Cialis, used to treat erectile dysfunction (ED). This undeclared ingredient may interact with nitrates found in some prescription drugs such as nitroglycerin and may lower blood pressure to dangerous levels. Men with diabetes, high blood pressure, high cholesterol, or heart disease often take nitrates.
Subject to a limited exception, it is a prohibited act under section 301(ll) of the FD&C Act [21 U.S.C. 331(II)] to introduce or deliver for introduction into interstate commerce any food to which has been added a drug approved under section 505 of the FD&C Act [21 U.S.C. 355] or for which substantial clinical investigations have been instituted and for which the existence of such investigations has been made public. Based on available evidence, FDA has concluded that the prohibition in section 301(ll) applies to tadalafil.1 FDA is not aware of any evidence that would call into question its conclusion that section 301(ll) of the FD&C Act prohibits the introduction into interstate commerce of any food to which tadalafil has been added.
Your Vital Honey product is a food to which tadalafil has been added. Therefore, the introduction or delivery for introduction into interstate commerce of this product is a prohibited act under section 301(II) of the FD&C Act.
3Unapproved New Drug
4 paragraphs
FDA reviewed your website at www.wholesaleonline1.com in June 2022 and determined you take orders there for the product Vital Honey. In addition to being a food of which the introduction or delivery for introduction into interstate commerce is prohibited under section 301(ll) of the FD&C Act, this product is a drug under section 201(g)(1)(B) of the FD&C Act [21 U.S.C. 321(g)(1)(B)], as established by the claims on your website, because it is intended for use in the cure, mitigation, treatment, or prevention of disease. As explained further below, introducing or delivering this product for introduction into interstate commerce for such uses violates the FD&C Act.
Examples of some of the website claims that provide evidence that your product is intended for use as a drug include:
- “Prevent arthritis and multiple sclerosis - Accelerating the healing and consolidation of fractured bones - Lower cholesterol - Alleviate cardiovascular ailments - Remedy liver disease, pancreatic, insomnia, fatigue, ulcers, and digestive and skin disorders - Reduce . . . anxiety states, insomnia and anorexia - Decreases prostate issues and illnesses in the man’s productive [sic] system.”
Your Vital Honey is not generally recognized as safe and effective for the above-referenced uses and, therefore, the product is a “new drug” under section 201(p) of the FD&C 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.
4Misbranded Drug
7 paragraphs
Your product Vital Honey is 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 product safely for its intended purposes. Accordingly, Vital Honey fails to bear adequate directions for its intended use and, therefore, the product is 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 this misbranded drug 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.
