Roseburg-based Purebulk, Inc received a letter from the FDA on Tuesday. In it the FDA writes that – ‘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.’
Caffeine is a powerful stimulant and the FDA says a single teaspoon of pure powdered caffeine is roughly equivalent to the amount in 28 cups of coffee.
Portland based Bridge City Bulk and three other companies across the country received warning letters from the FDA.
Because of powdered caffeine’s potency it can be hard to measure so the FDA wants the companies to improve their labeling and instructions.
