There are 5 stages of sleep and we cycle through them about every 90 minutes. The deep sleep stage (stage 4) is longer earlier in the night. This is where our body repairs itself and grows. But the longer we sleep and the more cycles we go through, this stage gets progressively shorter and the REM stage gets progressively longer. So when you cut short your sleep, you lose your longest REM stages.
Supplementation shouldn't be a guessing game. Unfortunately, most mainstream conventional manufacturers of vitamins and supplements would prefer you focus more on their marketing then on the ingredients in their products. Store shelves are filled with products containing potentially harmful ingredients and loaded with additives like stearates, artificial colors, artificial preservatives and fillers.
