1. Summary

The LiftMode Energy Stack is the first of its kind, combining seven top energizing and mood-lifting ingredients into a single capsule that delivers a powerful and unmatched energy-boosting experience. The Energy Stack primarily contains naturally extracted compounds such as Rhodiola Rosea extract, Yohimbine HCl, Caffeine, Hordenine, and Piperine, as well as endogenously (within the body) produced substances like Phenylethylamine (PEA). This is a great supplement for anybody with low energy looking for a natural boost!

All the ingredients in this stack are either produced by your body or are plant extracts. The LiftMode Energy Stack contains seven compounds, in specifically designated amounts, to produce the most synergistic relationship possible and to help reduce feelings of low energy.

The benefits of this supplement stack include a noticeable increase in physical energy, a substantial improvement in cognitive performance and mental focus, and significant mood-boosting effects [1 - 5]. Each LiftMode Energy Stack capsule has been specially formulated to deliver the optimal dosage of the active ingredients. Do not exceed the recommended serving size of 1-2 capsules, taken once to twice per day.

2. Constituents

The Energy Stack contains SEVEN key ingredients:


2.1. PEA (Phenylethylamine HCL) – 300mg

Phenylethylamine HCl (PEA) is an endogenously produced (made in your body) compound with powerful energizing and mood-lifting properties. It is often associated with ‘Runner’s High’, which is the feeling of euphoria that comes after intense cardiovascular exercise [1]. PEA is found in chocolate (e.g., pure cocoa) and other high-energy foods like fruits and dark green vegetables.


2.2. Hordenine – 75mg

Hordenine is a potent energizer that increases focus and mental energy. It is typically extracted from the Bitter Orange plant, along with other compounds like Synephrine and Ephedrine [2, 3]. Hordenine is an MAO-B substrate and it helps prolong the effects of PEA [4]. Furthermore, Hordenine is described as one of the most powerful energy-enhancing compounds in Bitter Orange [2, 4].


2.3. Ascorbyl Palmitate (Vitamin C) – 75mg

Vitamin C (Ascorbic acid) is a water-soluble vitamin that is essential for the health of our immune systems. It also acts as a powerful antioxidant that helps protect your body from toxins [5]. In addition, Vitamin C is often referred to as one of the top vitamins for boosting energy. Vitamin C also helps improve your body’s absorption of a number of minerals and other compounds (e.g. iron) [6].


2.4. Rhodiola Rosea Extract – 50mg

Rhodiola Rosea is an herb that grows in the Artic regions of Asia and Scandinavia and it has potent fatigue-reducing benefits [7]. While it is not typically used as an energizing supplement, its fatigue-reducing and mood-lifting properties make it a great addition to any energizing stack. Supplementing the diet with Rhodiola Rosea is definitely a great way to reduce feelings of low energy.


2.5. Caffeine – 50mg

Caffeine is the world’s most widely consumed stimulant and it is found in active concentrations of many teas as well as Coffea Arabica (coffee plant). Its benefits, which include heightened energy, enhanced mood, and improved cognition, are well-known to most people [8]. It also stimulates the release of calcium. Increasing levels of calcium lead to the activation of an enzyme called nitric oxide synthase and this process improves blood flow by causing blood vessels to gently expand [9]. Caffeine offers arguably the greatest natural energy boost on Earth.


2.6. Piperine – 20mg

Piperine, or Black Pepper Extract, is a powerful and unique mineral. It is especially unique in that it doesn’t really have any noticeable effects of its own, but is instead used to significantly improve the absorption of other nutrients by enhancing the activity of various enzymes in the liver [10]. This is the ‘secret’ ingredient that helps make the LiftMode Energy Stack one of the top supplements for energy.


2.7. Yohimbine HCl – 5mg

Yohimbine HCl is a very powerful plant compound found in the African Yohimbe tree. In Africa, it is used as a stimulant and energizer as well as a powerful aphrodisiac [11]. Research has also demonstrated Yohimbine HCl’s ability to boost mental focus, increase energy levels, and help maintain a healthy metabolism [12]. Important: People with anxiety should NOT use Yohimbine or products containing Yohimbine as it may exacerbate symptoms.

3. Human Effects

3.1. Boosts Physical Energy Levels

The LiftMode Energy Stack has been specially designed to optimize the energizing benefits of all its active ingredients. Hordenine and Phenylethylamine (PEA) are often taken together due to their powerful energizing properties [13], while Caffeine [14] and Yohimbine HCl [15] have potent energizing benefits of their own. These substances can all be used to reduce feelings of low energy. Each of these ‘energy-enhancing substances’ are combined with Rhodiola Rosea, which helps target fatigue, as well as Vitamin C and Piperine, both of which help improve nutrient absorption [16].


3.2. Improves Cognitive Performance

Caffeine has noticeable cognition-enhancing benefits, as does PEA [17] [18]. Therefore, this may be one of the first energizing supplement stacks that combines these natural cognition boosters. The LiftMode Energy Stack is recommended for anybody who needs a boost with studying or performing professional work as it helps improve mental focus and attention. More specifically, if you’ve ever wondered what it’s like to experience the best of the world’s most potent natural cognitive enhancers, then this is the capsule you’ve been looking for!


3.3. Increases Mood

Rhodiola Rosea extract,[19] Caffeine,[20] Phenylethylamine,[21] and Hordenine[22] (mildly) are all known for their mood-boosting effects. The LiftMode Energy Stack offers you the benefits of all four of these great natural mood-boosters! A better mood helps heighten your focus, helps you sleep better, and may even improve your health! In addition, when you combine all three benefits of this powerful new supplement stack – the energizing, cognition-enhancing, and mood-boosting properties – you’re sure to feel on top of the world!
