Evidence-Based Research




1. Summary

The LiftMode Sleep Stack is a powerful combination of four natural compounds to help promote healthy rest and relaxation. It is one of the most powerful natural sleep aids available. The supplement stack may also have beneficial effects on mood and immune function. LiftMode Sleep Stack contains a mix of Melatonin, Oleamide (both produced naturally by your body to induce sleep), with Vitamin C and Levo-Tetrahydropalmatine (L-THP).

The LiftMode Sleep Stack promotes relaxation, sleep, and a healthy immune system [1 - 4]. Additional benefits may include a noticeable improvement in mood, feelings of calm and relaxation, needing less time to fall asleep, and enhanced immune system function [1 - 7].

Each LiftMode Sleep Stack capsule has been specially developed to deliver the necessary amount of active compounds to produce the desired effects. A great natural alternative!

2. Constituents

The LiftMode Sleep Stack is designed by using a combination of powerful natural relaxation-inducing compounds. These are all either found in nature or are produced by your own brain (e.g. Oleamide and Melatonin). The four compounds in this supplement include:


2.1. Oleamide

Oleamide is an endogenous (produced in your body) compound that is derived from oleic acid, which is also found in olive oil. It has several interesting properties for people who are looking for a relaxing, sleep-promoting experience. Scientists associate Oleamide with the sleep process as it has been shown to accumulate in the human brain in response to sleep deprivation. A mere 6 hours of sleep loss increases Oleamide concentrations by around 4-6 fold [1]!


2.2. Ascorbyl Palmitate (Vitamin C)

Vitamin C is a well-known nutrient that is essential for the proper functioning of your immune system. What is not as well-known about vitamin C is that it assists in the absorption of many different supplements and minerals [2]. Furthermore, research has suggested that Vitamin C may help prevent memory impairment that is associated with sleep deprivation, possibly through its powerful antioxidant properties. [3] 


2.3. L-Tetrahydropalmatine (L-THP)

Tetrahydropalmatine (THP) is a plant alkaloid that is found in a number of different plant species, including the Chinese Corydalis genus (also known as Yanhusuo). It has been used in traditional Chinese medicine for hundreds of years as an herbal preparation to restore health and promote relaxation [4, 5]. Today, the more active levo- isomer is used (as L-Tetrahydropalmatine or L-THP). This particular compound has highly beneficial anti-inflammatory and antioxidant properties. It may also help promote a healthy mood and target stress,[5] which has been shown through research to have a positive influence on sleep [6].


2.4. Melatonin

Melatonin is the hormone that your body uses to regulate the circadian rhythms (sleep-cycles). More specifically, melatonin is produced by your pineal gland in response to changes in the light-dark cycle [7]. Accordingly, numerous studies have demonstrated its importance in the sleep process [8]. When taken as a supplement, Melatonin can be used as a sleep aid to help reduce the length of time it takes to fall asleep and to promote a calm, relaxed state of mind [9].

3. Human Effects


3.1. Improves Mood

Three of the ingredients in the LiftMode Sleep Stack have been shown to have highly beneficial effects on mood – namely, Oleamide, L-THP, and Melatonin [1, 5, 9]. In addition, research has indicated that sleep and mood are closely connected, as a lack of sleep can negatively affect your mood. However, your mood throughout the day can also disrupt your sleep and cause a problematic cycle [10]. This means that if you can’t sleep at night, a mood-boosting supplement may surely help! 

Research has also shown that mood may affect sleep latency (the time it takes to fall asleep) as well as the quality of REM sleep [11]. This is why supplements that support a better mood and promote relaxation may indirectly improve your sleep quality. These types of benefits are some of the top reasons that people are talking about the LiftMode Sleep Stack.


3.2. Supports Rest, Sleep, and Relaxation

Both Oleamide and Melatonin are known to support a calm, relaxed mood [1, 5]. These endogenous compounds are part of your body’s natural sleep-promoting system. When your brain detects darkness, it starts producing Melatonin to bring about a more relaxed state. At the same time, Oleamide is produced to promote sleep.

People usually use these two sleep-enhancing compounds on their own, and many people have been so impressed that they’ve taken the time to write positive reviews about both Melatonin and Oleamide. When taken together, and along with Vitamin C and L-THP, Melatonin and Oleamide have the potential to greatly assist with sleep!


3.3. May Help to Support a Healthy Immune System

There are two main reasons why the LiftMode Sleep Stack may help support a healthy immune system. First, better sleep improves your immune system [12]. This has been known for a long time, although the negative effects of sleep deprivation on the immune system are often underestimated. However, improving your sleep quality can have highly beneficial effects on your body’s ability to protect itself from dangerous toxins, viruses, bacteria, and reactive oxygen species (free radicals) [12].

Second, vitamin C and L-THP have been shown to support a healthy immune system [5, 13].  Vitamin C, in particular, is essential for a healthy immune system and a deficiency of this vital nutrient can have very detrimental effects on your body [13]. Similarly, research shows that L-Tetrahydropalmatine (L-THP) may also have highly beneficial effects on the immune system and even brain health [14].

4. Safety and Toxicity

4.1. Side Effects

LiftMode Sleep Stack may cause drowsiness if it is taken in large serving sizes during the day. It is recommended to use this product at night, about 2 hours before going to sleep. Do not use this product if you are taking any medication. If you are pregnant or breastfeeding, please consult with your doctor before using the LiftMode Sleep Stack.


4.2. Overdose

The LiftMode Sleep Stack is comprised of naturally occurring compounds that have a very high safety profile. It is extremely difficult to overdose on vitamin C, Melatonin, or Oleamide, as your body needs and produces these substances naturally to promote proper functioning. The effects of higher doses of Levo-Tetrahydropalmatine are less well-researched. However, this compound has a very long history of use in traditional Chinese medicine and is considered safe for use at the recommended serving size. Do not exceed the recommended serving of this supplement.
