This is to advise you that in January 2018, the U.S. Food and Drug Administration (FDA) reviewed the label for your 8 ounce Caffeine Anhydrous Powder product, which is labeled and offered for sale as a dietary supplement on your website, http://dualhealthsupplements.com. We further reviewed your website in March 2018. Your product is offered in powdered form, and its labeling lists “100% pure Caffeine Powder” as the sole ingredient.
Based on our review, we have determined that your 8 ounce Caffeine Anhydrous Powder product is adulterated within the meaning of section 402(f)(1)(A)(i) of the Federal Food, Drug, and Cosmetic Act (the Act) [21 U.S.C. § 342(f)(1)(A)(i)] because it is a dietary supplement that presents a significant or unreasonable risk of illness or injury under the conditions of use recommended or suggested in the labeling. You can find the Act and FDA regulations through links in FDA’s home page at http://www.fda.gov.
Your 8 ounce Caffeine Anhydrous Powder product label states, “Recommended Dose: 1/16 teaspoon (200mg). Servings: Take 1-3 times daily.”
A serving size of 200 milligrams cannot be accurately measured using common household measuring tools. Many consumers do not have a scale that is sufficiently precise to accurately measure such a small amount. Even if consumers were to have a 1/16 teaspoon measuring tool, as you suggest be used on your labeling, it would still not be adequate to accurately measure a 200 milligram serving because this tool can deliver a different amount depending on factors such as how tightly the powder is packed and whether a “heaping” scoop is used. Furthermore, a simple mistake such as measuring a serving in grams or fractions of a tablespoon, rather than milligrams or fractions of a teaspoon, could result in a dangerous or even toxic dose.
Caffeine is a powerful stimulant. A single teaspoon of pure powdered caffeine is roughly equivalent to the amount in 28 cups of coffee (approximately 2.7 grams). Consuming as little as one teaspoon of caffeine has been associated with symptoms including nausea, vomiting, anxiety, and heart palpitations. Consuming as little as one tablespoon (equivalent to 3 teaspoons or approximately 8.1 grams) of caffeine has been associated with symptoms including chest pain, hypokalemia, elevated blood glucose, tachycardia, bigeminy, agitation, respiratory alkalosis, irregular heartbeat, and in some cases, even death.
Your Caffeine Anhydrous Powder product consists of a package containing 8 ounces of powdered caffeine, which is approximately 227 grams. This is well over a thousand servings of your product, using your recommended serving size of 200 milligrams. (We also note that you sell your product in packages as large as 5.5 pounds, which is approximately 2,500 grams, and almost 12,500 servings of the product.) The conditions of use suggested by your labeling appear to imply that consumers have ready access to either a very precise scale or a 1/16 teaspoon measuring tool, and that a 1/16 teaspoon measuring tool can be used to accurately measure the recommended serving size of your product, when in fact that is not the case. In light of the potential toxicity of your product; the fact that your product is packaged to contain an amount that is potentially lethal many times over; the fact that the packaging requires the consumer to use a precise scale to separate out a safe serving from this potentially lethal amount; and the fact that your product labeling could be read to incorrectly imply that this process of separating out a safe serving from a potentially lethal amount can be done with certain volume measuring tools; we have determined that your product presents a significant or unreasonable risk of illness or injury under the conditions of use recommended or suggested in the labeling.
Moreover, a review of your website also shows that you sell similar-appearing products in package sizes ranging from 3.5 ounces to 5.5 pounds. While we have not reviewed these products, if they are similar to your 8 ounce product they would present the same issues as that product, with the added risk that the products larger than your 8 ounce product contain even more potentially lethal doses.
