Rest Well enhances restful, healing sleep by restoring healthy brain chemistry and produces better brain activity, mood, energy and hormonal balance. L-Tryptophan is an essential amino acid that produces a mood-enhancing neurotransmitter called serotonin. When the body is deficient in tryptophan, it also lacks serotonin. This can inhibit sleep and trigger numerous physical and/or mental disorders. Adequate levels of tryptophan are essential for biochemical balance of the brain.

Customerse Love Alkaline for Life Rest Well

I was skeptical, as I am an insomniac & have tried everything! This product is fabulous and is also mood boosting!

Angela M.

This has been a game changer for me with sleep. I was unable to sleep through the night for several years now. I started taking Rest Well and I immediately began sleeping through the night. Previously when I woke I would toss and turn and couldn’t get back to sleep for hours. Now if I wake, I roll over and go right back to sleep. Getting a restful night’s sleep makes such a difference in my day!

Rest Well is our formula designed to enhance restful and healing sleep while optimizing brain chemistry. Rest Well is a safer alternative to habit-forming pharmaceutical sleep aids, because it works by boosting the body’s own production of serotonin using natural precursors and cofactors.

The main ingredient in Rest Well is L-Tryptophan, one of the 9 essential amino acids, yet is one of the least abundant in the diet, accounting for an estimated 1% of dietary protein intake (1). Tryptophan is the only dietary precursor to serotonin, a mood-enhancing neurotransmitter, responsible for many functions including regulating our sleep-wake cycle. 

Because of this, insufficient levels of tryptophan can cause detrimental effects to your sleep cycle, energy levels, mood, and concentration (1). 

Why is Rest Well better than other sleep-aid supplements?

Rest Well uses L-Tryptophan, which can cross the blood-brain barrier and efficiently convert to serotonin. Rest Well also delivers active forms of vitamin B-6 and riboflavin, which maximize the absorption of tryptophan, giving rise its sleep and mood-enhancing properties. Common sleep supplements include melatonin or5-HTP, but tryptophan is the precursor for both of those substances. In fact, ingesting tryptophan increases plasma levels, and doubles the synthesis of 5-HT in the brain (2). Supplementing tryptophan gives the body the tools it needs to convert into each intermediate compound involved in sleep-wake cycles. Most importantly, because tryptophan is found naturally in food, we see less side-effects than with sleep medications or other supplements.

Unique Qualities of Rest Well:

·      Paired with cofactors that help to convert tryptophan to 5-HT, serotonin, and melatonin

·      Pharmaceutical-grade ingredients

·      Nutrients in their most bioavailable, natural forms

·      Free of citrus, MSG, wheat/gluten, corn/zein/starch, dairy/casein, whey/milk derivatives, yeast, soy, sulfate, phosphates (other than coenzymes), and preservatives, GMOs.
