01Other · 21 CFR 170.30(a)-(c)Your Roxy Instamix Complex Alkaloid Drink Mix is adulterated because it contains kratom extract, an unsafe food additive.
There is no food additive regulation that authorizes the use of kratom extract in food. We are not aware of any information to indicate that kratom extract is the subject of a prior sanction (see 21 CFR Part 181). Furthermore, we are not aware of any basis to conclude that kratom extract is GRAS for use in conventional foods. FDA's regulations in 21 CFR 170.30(a)-(c) describe the criteria for eligibility for classification of a food ingredient as GRAS. The use of a food substance may be GRAS based on either scientific procedures or, for a substance used in food before 1958, through experience based on common use in food (see 21 CFR 170.30). We know of no basis for general recognition of safety for kratom extract based either on scientific procedures or common use in food prior to January 1, 1958. Based on our review of published scientific literature, existing data and information do not provide an adequate basis to conclude that the use of kratom extract in food meets the criteria for GRAS status. Therefore, based on our review, the use of kratom extract in conventional food does not satisfy the criteria for GRAS status under 21 CFR 170.30.

AddressedDear Messrs. Surani and Manjiyani

1Introduction

2 paragraphs

This letter concerns your products Roxy Instamix Complex Alkaloid Drink Mix (in passion fruit flavor) and ROXY 7-OH tablets, (15mg and 16mg), ROXY+ 7-OH 20mg tablets, and ROXY XL 7-OH 60mg tropical flavor tablets (hereinafter “your 7-OH Tablets”), offered in different flavors and/or package sizes. Your product labeling for these products represent that the products contain 7-hydroxymitragynine (7-OH).1 As explained further below, introducing or delivering these products for introduction into interstate commerce violates the Federal Food, Drug, and Cosmetic Act (the Act). You can find the Act and FDA regulations through links on FDA’s home page at www.fda.gov.

FDA has observed a proliferation of products containing 7-OH, and has serious concerns about products containing 7-OH. The concerns include the following: 1) 7-OH products have not been evaluated by FDA for safe use; 2) FDA has received adverse event reports associated with 7-OH containing products; and 3) 7-OH has been reported to have opioid-like effects.

2Adulterated Human Foods: Unsafe Food Additive

6 paragraphs

Based on a review of your product labeling, your Roxy Instamix Complex Alkaloid Drink Mix, in passion fruit flavor, is a multi-ingredient food that contains 7-OH that is supplied by the addition of kratom extract to this food.

As defined in section 201(s) of the Act (21 U.S.C. 321(s)), the term "food additive" refers to any substance the intended use of which results in it becoming a component of any food, unless the substance is generally recognized as safe (GRAS) among qualified experts under the conditions of its intended use, or unless the substance meets a listed exception.2

Food additives require premarket approval based on data demonstrating safety. Any food additive that has not been approved for its intended use in food is deemed to be unsafe under section 409(a) of the Act (21 U.S.C. 348(a)) and causes the food to be adulterated under section 402(a)(2)(C)(i) of the Act (21 U.S.C. 342(a)(2)(C)(i)). Introduction of an adulterated food into interstate commerce is prohibited under section 301(a) of the Act (21 U.S.C. 331(a)).

There is no food additive regulation that authorizes the use of kratom extract in food. We are not aware of any information to indicate that kratom extract is the subject of a prior sanction (see 21 CFR Part 181). Furthermore, we are not aware of any basis to conclude that kratom extract is GRAS for use in conventional foods. FDA's regulations in 21 CFR 170.30(a)-(c) describe the criteria for eligibility for classification of a food ingredient as GRAS. The use of a food substance may be GRAS based on either scientific procedures or, for a substance used in food before 1958, through experience based on common use in food (see 21 CFR 170.30).

We know of no basis for general recognition of safety for kratom extract based either on scientific procedures or common use in food prior to January 1, 1958. Based on our review of published scientific literature, existing data and information do not provide an adequate basis to conclude that the use of kratom extract in food meets the criteria for GRAS status. Therefore, based on our review, the use of kratom extract in conventional food does not satisfy the criteria for GRAS status under 21 CFR 170.30. Moreover, some of the available data raise serious concerns about potential harm associated with kratom extract. Our review of published scientific literature and adverse event reports related to consumption of kratom and kratom-derived products raise a number of safety concerns, including liver toxicity, cardiovascular toxicity, seizures, gastrointestinal distress, respiratory depression, addiction, withdrawal symptoms, and death. It’s not clear from available evidence whether all of these effects were due to mitragynine or 7-OH (i.e., two of the main alkaloids found in kratom) in these products. Although 7-OH is a minor component of kratom, it is a more potent inducer of opioid-like effects than the primary kratom alkaloid, mitragynine, and mitragynine converts to 7-OH in the body. Because of this, products containing enhanced levels of 7-OH are of particular concern because we anticipate an increased risk of adverse effects as the dose of 7-OH increases.

FDA is not aware of any other exception to the food additive definition that would apply to kratom extract for use as an ingredient in a conventional food. Therefore, kratom extract when added to a conventional food is a food additive under section 201(s) of the Act and is subject to the provisions of section 409 of the Act. Under section 409, a food additive is deemed unsafe unless it is approved by FDA for its intended use prior to marketing. Kratom extract is not approved for use in any conventional food. Food containing an unsafe food additive within the meaning of section 409 is adulterated within the meaning of section 402(a)(2)(C)(i) of the Act. Therefore, your Roxy Instamix Complex Alakaloid Drink Mix (in passion fruit flavor) is adulterated within the meaning of section 402(a)(2)(C)(i) of the Act because it bears or contains an unsafe food additive. The introduction or delivery for introduction of an adulterated food into interstate commerce is prohibited under section 301(a) of the Act (21 U.S.C. 331(a)).

Examples of claims from your website that provide evidence of the intended use of your products as drugs include, but may not be limited to, the following:

Your 7-OH Tablets are not generally recognized as safe and effective (GRASE) for their above referenced uses and, therefore, these products are “new drugs” under section 201(p) of the Act (21 U.S.C. 321(p)). Subject to certain exceptions not applicable here, new drugs may not be legally introduced or delivered for introduction into interstate commerce without an approved application from FDA in effect, as described in sections 301(d) and 505(a) of the Act (21 U.S.C. 331(d) and 355(a)). There are no FDA-approved applications in effect for your 7-OH Tablets.
