While Nutrex isn’t exactly breaking new ground with the ingredients in Hibern8, it does feature a transparent label and straightforward blend of sleep-promoting ingredients. Hibern8 Ingredient Breakdown GABA(gamma aminobutyric acid): GABA is a neurotransmitter which binds to receptor sites in the brain and has a calming effect on nerves. This calming effect promotes better sleep, relaxation, and reduces anxiety. L-Tryptophan: L-Tryptophan is an amino acid that converts to the neurotransmitter serotonin, which plays a role in mood, memory, and learning. What’s more, the body uses serotonin to produce melatonin, and further induce natural sleep. Melatonin: A natural hormone produced by the body’s pineal gland, melatonin regulates circadian rhythm and facilitates healthy, natural sleep. [1] A Word of Caution When Taking Hiber8 You’ll definitely want to follow the recommended dosage directions and start with 1 pill to assess tolerance. I started with 1 serving (3 pills), and it completely knocked me out. I was asleep in about 10 minutes and overslept something like 11 hours. I wasn’t groggy when I woke up, but I definitely should’ve started with just 1 pill instead of 3. Personally I’m very sensitive to melatonin, and the full 5 mg was too much for me. If you’re also melatonin-sensitive, keep in mind that each pill has about 1.5 g of melatonin. Price and Availability Although Hibern8 is only available on the official Nutrex website, they are running a promo for buy 2 get 1 free. Each individual bottle is $49.95, so the promo saves you about $17 and brings the price of each bottle to $33. Hibern8 Bottom Line I would definitely recommend Hibern8 to anyone that has trouble relaxing and falling asleep at night. The majority of your growth hormone is released at night, and if you’re trying to maximize the body’s natural growth hormone release, there’s nothing better than a good night’s sleep.
