Shocking Study Reveals 22 out of 25 Melatonin Products Were Mislabeled

Have you ever taken a melatonin supplement to help you fall asleep? If so, a recent study has shown that there is a good chance that the product you bought was mislabeled. The study found that 22 out of 25 melatonin products tested were mislabeled, with the actual melatonin content in the products often different from what was stated on the label.

Proof of the Problem Surrounding Melatonin Dosages

The study was conducted by researchers at Brigham and Women’s Hospital in Boston, who purchased melatonin supplements from various retail stores and websites. The researchers found that the amount of melatonin in the supplements ranged from as little as 83% of the amount listed on the label, to as much as 478% of the amount listed. In some cases, the supplements also contained other ingredients that were not listed on the label.

Lead author Dr. Andrew W. Varga, a sleep specialist at Brigham and Women’s Hospital, expressed concern about the findings, stating that "Our results suggest that patients may not be getting the dose of melatonin that they expect from these products, and worse, they may be unknowingly consuming other substances that are not disclosed on the label."

The Importance of Reliable Sleep Support Supplements

Given the potential issues with mislabeled melatonin products, it's important for consumers to seek out reliable sleep support supplements. One such option is Knocked, a sleep support supplement that contains a blend of natural ingredients, including Magnesium Glycinate, L-Theanine, and Apigenin. Magnesium Glycinate is a form of magnesium that is easily absorbed by the body, and it has been shown to help improve sleep quality. L-theanine is an amino acid that is found in tea leaves, and it has been shown to help reduce stress and promote relaxation. Apigenin is a flavonoid that is found in chamomile, and it has been shown to have sedative properties.

Knocked is formulated to help you fall asleep faster and stay asleep longer, without the risk of mislabeled or undisclosed ingredients. The product is also non-habit forming, so you don’t have to worry about becoming dependent on it to get a good night’s rest.

Final Thoughts

The mislabeling of melatonin products is a serious issue that can have negative consequences for consumers. However, by choosing reliable sleep support supplements like Knocked, consumers can improve their sleep quality and avoid the potential risks associated with mislabeled melatonin products.
