Are you ready to wake up refreshed  feeling like you got a truly good night’s sleep? Quantum Nutrition Labs is proud to offer an all new, superior lifestyle formula geared to promote deep sleep, optimal relaxation, and mental tranquility. This formula features legendary ingredients selected for their compounds that deliver incredible support for mood and emotional balance.* These compounds also help promote a healthy response to an overactive mind and encourage deep, restful sleep.*  

Quantum Relax and Slumber now contains an all-star lineup of the prized ingredients, including magnolia bark extract, a unique Organic saffron extracta special absorbable form of magnesium, valerian root extract, and a clinically studied L-theanineEach of these botanical agents have been selected for their effective phytochemical compounds and nutritional benefits.* Overall, this formula supports deep sleep, emotional balancerelaxation, healthy mood, and mental tranquility.* 

Magnolia Bark: An Ancient, Highly Prized Herb 

Our first key ingredient, magnolia bark, has an ancient history of use in traditional Chinese healthcare. The effectiveness of magnolia bark is usually chalked up to its naturally occurring diphenyl compounds, magnolol and honokiol, which may work to promote stress management.* Magnolia bark can also assist in facilitating refreshing, deep sleep.* 

Mighty Magnesium: Are You Getting Enough?

Our second key ingredient is magnesiuman essential mineral that helps support brain and muscle tissue.* Magnesium also helps support the regulation of muscle contraction, blood pressure, and the synthesis of DNA, RNA, and protein.* This powerhouse nutrient is required for the catalytic action of more than 300 enzymes in the human body, including the conversion of tryptophan to serotonin. Adequate levels of serotonin are a major determinant for mental health and healthy mood.* In addition, a specialized bioavailable chelated form of magnesium is used called magnesium malate. This form of magnesium has been shown to be capable of crossing the blood brain barrier.  

Safr’InsideTM: A Forgotten Herb with a Great Reputation

Nicknamed the “sunshine spice”, saffron, our third key ingredient, has earned a reputation of being the world’s most expensive spice due to the highly labor-intensive process required in harvesting this magical herb. This is because the stigma and styles, called threads, of this vibrant purple flower must be collected by hand and then dried for use as a spice or in nutritional formulas worldwide. However, the fuss over processing this amazing herb is well worth it because its benefits are vast, with an impressive variety of plant compounds that can act as antioxidants and also help elegantly support healthy mood.* The specific saffron extract, Safr’Inside™, used in this unique formula is 100% Persian grown and then soft-extracted in France. The unique extraction process ensures the full spectrum of over 25 unique mood and sleep modulating compounds from the plant are present. This unique extract is significantly richer in these natural compounds than other extracts on the market. 

Suntheanine®: The Body’s Relaxation Friend

Since ancient times, it has been thought that drinking green tea promotes relaxation. Researchers have found that this relaxation effect is due primarily to the presence of the amino acid L-theanine, found almost entirely in tea.  Our fourth key ingredient, Suntheanine®, was created to make this amino acid available in its pure form.  This unique ingredient is not an extract of green tea but rather is produced via a patented enzymatic fermentation process that mimics the natural process in green tea leaves, resulting in a 100% pure L-isomer form of theanine that contains no caffeine. It has been clinically researched and is backed by more than 40 U.S. and international patents.  Human clinical trials have shown that Suntheanine® helps promote an increase in healthy alpha wave brain waves (and decrease in Beta brain waves), which is associated with a relaxed but alert mental state.*

The immune system is an incredibly complex network of organs, tissues, glands, and cells that find and respond to harmful foreign invaders like viruses and bacteria, which can cause disease. The immune system relies on various micronutrients, such vitamin A, vitamin C, vitamin D, vitamin E, selenium, beta-carotene, iron, and zinc, for optimal functioning. Deficiencies in these and other phytonutrients can lead to increased risk for infection and longer recovery periods.

Ideally, we would get all the essential immune-boosting vitamins and minerals we need by eating nutritious foods. However, it can be difficult to maintain a balanced diet for many reasons. Even if you consume a nutrient-rich diet, industrial farming practices have eroded the microbiome of the soil our food is grown in and with it the nutritional value of most food products. As a result, it's critical to take targeted supplements that support your immune system.
