NSP Melatonin vs. the competition
We used High Performance Liquid Chromatography (HPLC) to measure the amount of melatonin in randomly selected samples of popular brands of melatonin products. We then compared the actual amount of melatonin found in each sample to the amount listed on the corresponding product labels. As you can see, most of the products tested fell short of their label claims, some substantially. One sample exceeded its label claim by 57 percent, which may be more melatonin than some customers want. Trust Nature’s Sunshine to provide you with products that have exactly what the labels indicate.
