If that holds here, melatonin would be a high share of the serving’s weight, and that is why we stopped on this number. But we did not weigh these gummies. The 2.5–3.5 gram figure is a general estimate for the format, not a measurement of this product. One published number would settle it: the weight of one gummy, or of a 4-gummy serving.
