What drew me to this product was the BioPerine complex. Known to enhance the bioavailability and absorption rate of nutrients, I wanted to see how it worked with a gentler sleep supplement than the Endocrine PM I reviewed a few weeks ago. The ingredients in Power to Sleep are all things that I have used individually to supplement my sleep, and I wanted to see what happened when you put them together.
A unique formula is designed to help you relax before bed, sleep soundly through the night, and wake up feeling refreshed in the morning.
Additional Ingredients: Soybean oil, gelatin, glycerin, purified water, soy lecithin, beeswax, titanium dioxide, caramel color, and red cabbage powder.
Following the bottle’s directions, I took 2 of the largish beige-and-brown liquid soft-gels 30 minutes before bedtime. I had no real trouble falling asleep, and I stayed asleep for 7.5 uninterrupted hours. I did wake up a little foggy, but I was already in a sleep deficit, and figured I just needed a full 8+ hours to avoid the grogginess. I tried it again the following night, and after 8.25 hours of sleep, I woke up alert and clear-headed — a co-worker even asked me if I had done anything to my skin, because I looked so refreshed.
As much as I liked this supplement, I will have a hard time adding it to my rotation of sleep supplements. What turns me off to this supplement is the (unnecessary) addition of soy and soy lecithin to the pills. I cut soy out of my diet a few years ago, mainly because of the negative effects it can have on thyroid function, reproductive health, and breast cancer risk (more research is needed on these subjects and soy’s influence, but this study was enough for me to take pause).
Add to that the fact that the soy in these pills is likely GMO, a genetically modified organism, (most non-GMO products make a point of advertising that fact), and that the BioPerine may make the isoflavones in soy more easily absorbable, and Power to Sleep is just not a supplement I would want to take on a regular basis. If Irwin Naturals decides to remove the soy for the formulation, I will be the first in line to buy a new bottle — it was that effective. For those who aren’t worried about soy and GMO (both topics which I believe need more research to show long-term effects), this could be a solid choice.
