WARNING LETTER
VIA CERTIFIED MAIL, RETURN RECEIPT REQUESTED

Natasha Trenev, President
Natren

Ref. No. 02-07

Dear Ms Trenev:

This letter concerns your marketing of the products, Gy-Na-Tren Vaginal Health Solution (Gy-Na-Tren), Life Start, CanineDophilus, FelineDophilus, and EquiFlora on your website, www.natren.com. According to these products' labeling, including information on your website, www.natren.com, Gy-Na-Tren (oral and vaginal capsules), Life Start, and CanineDophilus are drugs within the meaning of section 201(g) of the Federal Food, Drug, and Cosmetic Act (the Act), 21 USC 321(g), because they are intended to prevent, treat, or cure disease conditions in humans and animals. FelineDophilus, and EquiFlora are drugs because they are intended to affect the structure or function of animal bodies. CanineDophilus is also intended to affect the structure or function of the animal body. In addition, Gy-Na-Tren (vaginal capsules) is intended to affect the structure or function of the human body. The marketing of these products violates various provisions in the Federal Food, Drug, and Cosmetic Act as described below.

Human Drug Products

GY-Na-Tren Vaginal Health Solution (Gy-Na-Tren)

Your human drug product, Gy-Na-Tren, is a kit containing one 14-capsule bottle of an oral preparation and one 14-capsule bottle of a vaginal preparation. Both preparations bear the name MEGA DOPHILUS, are labeled as dietary supplements, and contain the ingredient "Lactobacillus acidophilus."

The following statements from your package labeling document the intended use of the Gy-Na-Tren product (both vaginal and oral capsules) for yeast overgrowth, a disease condition:

Outer carton labeling
  • "Clinically Proven … Safe, effective, natural beneficial flora L. acidophilus, NAS super strain in veggie and gelatin capsules for yeast overgrowth"
  • "Suggested Use for Best Results: 1) Take one oral capsule daily (green label bottle), just before a light meal … 2) Insert one capsule vaginally daily (pink label bottle), before bedtime"

The following statements from your package labeling and insert document the intended use of the Gy-Na-Tren product (vaginal capsules) to affect the structure or function of the human body:

Outer carton labeling
  • "scientifically proven to promote a positive balance in the vaginal and intestinal ecology when taken as directed"
Outer carton labeling
  • "Megadophilus vaginal caps taken on a daily basis provide billions of colony-forming units of L. acidophilus NAS super strain — considered by the scientific community to assist in providing a positive balance in vaginal flora."
Life Start According to your website, Life Start is a milk-based probiotic product for infants containing the bacterium "Bifidobacterium infantis." The product is labeled as a dietary supplement and sold in powder form. The following statements from your website document the intended use of the Life Start product as a human drug:

While your website and other labeling represent Gy-Na-Tren, including both the oral and vaginal preparations, and Life Start as dietary supplements, the labeling statements quoted above make clear that Gy-Na-Tren, promoted for yeast overgrowth, and Life Start, promoted to prevent allergies and asthma and for use during infections in conjunction with antibiotics, are intended for use in the diagnosis, cure, mitigation, treatment, or prevention of disease. Therefore, these products meet the definition of a drug and are subject to regulation as such. Additionally, the route of administration of the vaginal Gy-Na-Tren capsule eliminates this product from the dietary supplement definition found in 21 USC 321(ff)(2)(A)(i) of the Act, to mean a product that is intended for ingestion. Accordingly, Gy-Na-Tren and Life-Start are drugs as defined by section 201(g)(1) of the Act, 21 USC 321(g)(1). Furthermore, Gy-Na-Tren and Life Start are new drugs under section 201(p) of the Act, 21 USC 321(p) because they are not generally recognized by qualified scientific experts as safe and effective for their labeled uses. The disclaimer on Gy-Na-Tren's labeling stating that it is not intended to diagnose, treat, cure, or prevent any disease, does not alter the fact that the claims made for your product in its labeling, including your website, cause it to be a drug as defined by section 201(g)(1) of the Act, 21 USC 321(g)(1). As new drugs, Gy-Na-Tren and Life Start may not be legally marketed in the United States because neither product is the subject of an approved application as required by Section 505 of the Act, 21 USC 355. Furthermore, Gy-Na-Tren is misbranded under section 502(o) of the Act, 21 USC 352(o) because it is not manufactured, prepared, propagated, compounded or processed in an establishment duly registered under section 510 of the Act, 21 USC 352(o), nor is it included in a list required by section 510(j) of the Act, 21 USC 360(j).

Human Drug Products

CanineDophilus, FelineDonhilus and EquiFlora

The statements noted below appear on your website and document the intended uses of your animal drugs.

The following statements from your website document the intended use of CanineDophilus to prevent and treat disease in animals as well as affect the structure or function of the animal body:

The following statements from your website document the intended use of FelineDophilus and Equiflora to affect the structure or function of the animal body:

Next, CanineDophilus, FelineDophilus, and EquiFlora are new animal drugs under section 201(v) of the Act, 21 USC 321(v), because they are not generally recognized by qualified scientific experts as safe and effective for their labeled uses.

CanineDophilus, FelineDophilus, and Equiflora are unsafe under section 512(a)(1) of the Act, 21 USC 360b(a)(1), because they are new animal drugs for which your firm does not have an approved application. Because they are unsafe under section 512 of the Act, 21 USC 360b, they are adulterated under section 501(a)(5) of the Act, 21 USC 351(a)(5). Furthermore, the agency has concluded that the Dietary Supplement Health and Education Act of 1994 does not apply to products intended for use in animals, see 61 Fed. Reg. 17706 (Apr. 22, 1996).

This letter is not intended to be an all-inclusive review of the products that your firm markets. It is your responsibility to ensure that all products marketed by your firm comply with the Act and its implementing regulations.

We request that you take prompt action to correct the noted violations. Failure to promptly correct these violations may result in enforcement action being initiated by the Food and Drug Administration without further notice. These actions include, but are not limited to, seizure, injunction, and/or civil penalties. In addition, federal agencies are advised of the issuance of Warning Letters pertaining to drugs so that they can consider this information when awarding contracts.

Please advise this office, in writing and within fifteen (15) working days of the receipt of this letter, as to the specific steps you haven taken to correct the violations noted above and to ensure that similar violations do not occur. If corrective actions cannot be completed within fifteen working days, state the reason for the delay and the time within which the corrections will be completed.

Your reply should be addressed to:

Pamela B. Schweikert
Director, Compliance Branch
US Food and Drug Administration

Sincerely,
