Description

The Sleep Time formulation, to be taken 1 hour before bed, is designed to improve problems with sleep.* Sleep Time was formulated to help support the neurotransmitters dopamine and serotonin, which have a role with sleep cycles and anxiety.*

Neurotransmitters are natural chemical messengers in the nervous system that send signals from one nerve cell across a synapse to another nerve cell or target organ. Serotonin plays a role in sleep, mood, intestinal function, pain control, and inflammation. Dopamine plays a role in cognitive function, memory, learning, and pleasure. In our bodies, dopamine is released as a result of rewarding experiences. Certain nutrients and amino acids may help to balance levels of neurotransmitters by providing co-factors that assist in the body’s ability to manufacture neurotransmitters.*

About the Ingredients
Gamma aminobutyric acid (GABA)
 is a naturally occurring amino acid that works as a neurotransmitter in your brain. Neurotransmitters function as chemical messengers. GABA is considered an inhibitory neurotransmitter because it blocks, or inhibits, certain brain signals and decreases activity in your nervous system. When GABA attaches to a protein in your brain known as a GABA receptor, it produces a calming effect. This can help with feelings of anxiety, stress, and fear. It may also help to prevent seizures. As a result of these properties, GABA has also become a popular supplement in recent years. This is partly because it isn’t available from many food sources.

L-Taurine- is an essential amino acid is a GABA-receptor agonist, meaning it produces a GABA-like effect in the body. GABA is a sedating, inhibitory neurotransmitter. In animal studies, application of taurine with GABA, or taurine with glycine produced stronger effects than taking either glycine or GABA alone. Taurine is can be used to enhance sleep quality.

Suntheanine® (L-Theanine) stimulates activity in the brain known as alpha waves, which are associated with a relaxed but alert mental state. Human clinical trials have shown Suntheanine® to promote an alert state of relaxation without drowsiness, as indicated by an increase in Alpha brain waves, and a decrease in Beta brain waves. Suntheanine® is protected by over 40 U.S. and international patents for its various physiological efficacies and L-isomer specific production processes.

L-Glycine- is a non-essential amino acid. It has been used to protect brain cells after ischemic stroke. Glycine is also thought to promote a sense of well-being and reduce anxiety. Research has shown that glycine can subjectively and objectively improve sleep quality. In a study where people’s sleep was restricted, glycine also reduced daytime sleepiness.

5-HTP- stands for 5- hydroxytryptophan, and is used by the body to make serotonin. 5-HTP is not found in food sources, the body manufactures 5-HTP from tryptophan, an amino acid found in dietary protein. Many conditions have been shown by studies to be helped by 5-HTP supplementation, including insomnia, depression, fibromyalgia, obesity (by reducing appetite), and headaches. 5-HTP should always be used under the supervision of a healthcare practitioner. In addition, the lowest possible dose should be used first and the dose should be titrated up slowly. 5-HTP should not be taken concurrently with pharmaceutical anti-depressants unless otherwise directed by your healthcare practitioner.

Vitamin B-5 (D-Calcium pantothenate)- is a water-soluble B vitamin with numerous biological roles. Vitamin B-5 is used by the body to manufacture, among other things, coenzyme A which is an important compound for energy metabolism and the production of fatty acids, cholesterol, and the neurotransmitter acetylcholine. D-Calcium pantothenate is the preferred, metabolically active form of B-5 used in higher quality nutritional supplements.

Vitamin B-6 (Pyridoxal 5-phosphate)- is a water-soluble B vitamin that performs many functions in the body. B-6 – dependent enzymes assist in the biosynthesis of the important neurotransmitters GABA, dopamine, serotonin, epinephrine, and norepinephrine. Pyridoxal 5-phosphate is the preferred, metabolically active form of B-6 used in higher quality nutritional supplements.

Melatonin- is a hormone naturally produced by the body to regulate circadian rhythm (sleep-wake cycle). Melatonin secretion may be disrupted by aging, hormonal changes, and night-time exposure to light, among other things. Melatonin supplements are well known for their ability to combat insomnia.

Very comfy sheets, nice fabric
Size: Full, Color: Oatmeal
I wasn’t expecting such good quality forthis price. They’re very soft, but of fairly thick fabric. I’m sleeping great on them. The pockets are deep enough for an 8” foam mattress plus my 3” topper. Will be getting another set for the second bedroom.

Great Sheets!
Size: Twin, Color: Oatmeal
Super soft, wash up beautifully, seem well made — very happy! It’s very hard to find 100% cotton t-shirt type sheets and these are really lovely.

Weirdly textured
Size: King, Color: Dark Gray
I have bought and loved jersey sheets in the past, that have all been as soft as a well worn cotton t-shirt. These arent soft. They have the stretch of jersey, but not the soft smooth texture that they should have. Even after washing a few times these are one of my least favorite sheets I've ever bought on Amazon.

Soft, Breathable Sheets That Feel Great to Sleep On
Size: Twin, Color: White
This Amazon Basics jersey sheet set was a really good purchase. The cotton material is soft, stretchy, and breathable — it feels like sleeping in a comfortable T‑shirt. The fitted sheet has a nice snug fit that stays in place, and the flat sheet is lightweight without feeling flimsy. The fabric washes well, doesn’t pill, and stays soft after multiple loads. It’s a great everyday sheet set for anyone who likes that cozy, relaxed jersey feel. Overall, comfortable, easy to care for, and great value for the price.

The Perfect Sheets To Lie On While Writing Amazon Reviews
Size: Full, Color: Light Gray
As I write this, I am laying on an adjustable full sized bed by Hofish and a 10.5" comfort foam mattress by Classic Brands. I know I sound like I am an Amazon plant, but I swear I am not. I'm not even a stockholder anymore. This is the most awesome bed stylings combination I have had in many, many years. In fact, it is the best I have ever owned and it is beat only by some ritzy resort I stayed at on vacation like 20 years ago, though I admit I was pretty drunk the entire time so my memory might not be the most accurate. But getting back to today... these sheets are great. I washed them twice - I'm not a neat freak, I am just amazingly disorganized and easily distracted while doing laundry, so tonight they went though two wash cycles and one dry. And then I put them on the bed. While these sheets are not deep pocket sheets, they don't need to be with this mattress. There is enough room and border for them to tuck and wrap with the elastic to give a strong grip under the mattress, which is important as the adjustable frame continually put the sheets and mattress though its repeated adjustable calesthenics-type positioning. The other two sheet sets I have used since I got this bed have struggled poorly with this. In the day or so and at least a dozen position changes, these sheets stay in place with no popped corners to exposing the bowl as the head and feet rise. Of course, till will tell if it lasts, but so far they are the best of the batch of sheets in my closet. As for texture, they are awesome. I'm a dude. I don't really know what thread count or knit or whatever really means. But these sheets feel like a well-washed favorite, quality rock & roll concert t-shirt. And not one of these glitter puff stupid new groups, like a real rock band from the 80s that now charges $250 for a concert ticket and $60 for a t-shirt...but that group you saw back then, paid $10 for the shirt and you STILL have it and love to wear it because it is perfectly molded to your body, soft and reliable. The kind of shirt you will wear under your suit at work and just grin not just for mental middle finger to corporate dress codes, but because the t-shirt is just that great of a feeling. Well, that is what these sheets feel like. And now you get to sleep in it. It is that awesome. In LA right now we are having a nasty heat wave, but these sheets don't seem to bake me even with my stuttering AC. The flannel sheets I love seem to trigger the butt sweats as soon as I lay down in this heat, but no such problem with these. So really, I'm absolutely happy with these things. I am going to order more in other colors as soon as Amazon gets them back in stock. Great price, great quality, great comfort, great fit, great deal. It is that simple.
