Caffeine helps with several key aspects of performance:
Performance Lab® Stim improves caffeine’s performance-enhancing effects with an innovative dual-stack formula designed for cleaner, calmer stimulation.
L-Theanine + Caffeine is popularly used to reduce caffeine side effects. Human clinical trials also show L-Theanine + Caffeine may produce a superior stimulation state to caffeine alone, as evidenced by:
L-Theanine’s additional mood, creativity and relaxation benefits also pair well with caffeine stimulation.
Performance Lab® Stim is designed with 2:1 Suntheanine® L-Theanine to natural caffeine, mirroring the ratio and form used in the most successful human research studies.
Caffeine stimulation increases demands on the body’s central nervous system (CNS), endocrine system and cardiovascular system. When these systems are stressed, caffeine side effects may manifest.
Performance Lab® Stim counterbalances caffeine demands with Suntheanine® L-Theanine, Ajipure® L-Tyrosine and NutriGenesis® B-Vitamins.
|Caffeine Demands||Performance Lab® Stim Counterbalance|
Increases demand on neurotransmitters:
L-Tyrosine – Supports dopamine, norepinephrine, epinephrine
L-Theanine – Promotes dopamine and serotonin
B-Complex – Supports serotonin and norepinephrine; catalyzes conversion and utilization of serotonin and dopamine
|Decreases Alpha brain waves||L-Theanine – Raises and sustains Alpha brain waves|
|Creates fight-or-flight stress that activates hypothalamic pituitary adrenal (HPA) axis; stimulates adrenal glands to release stress hormone cortisol||
L-Theanine – Regulates cortisol and promotes relaxation
L-Tyrosine – Optimizes mental and physical performance under stress
B-Complex – Helps meet increased demands of stressed adrenals
|Constricts blood vessels, raising blood pressure; accelerates heart rate||L-Theanine – Helps to maintain healthy blood pressure within normal range; helps to reduce resting heart rate|
|Diuretic effects increase excretion of B-Vitamins needed for cell energy and brain chemical synthesis||B-Complex – Highly absorbable NutriGenesis® B-Vitamins to help restore what caffeine takes away|
|Raises homocysteine (HCY) levels; high HCY linked to brain fog and memory issues||B-Complex – Contributes to daily B6, B9 and B12 intake required for healthy homocysteine metabolism|
When taken correctly, caffeine is a leading natural performance enhancer. However, too much caffeine can lead to overstimulation that paradoxically worsens performance:
To get the best performance benefits, individuals must determine their own optimal caffeine dose and manage caffeine intake accordingly.
This can be challenging for those who consume caffeine from many different sources.
Stim’s 50 mg dose improves caffeine intake control – whether taken alone or combined with coffee, energy drinks or other Performance Lab® formulas.
L-Theanine is an amino acid found in green tea that raises the brain’s Alpha wave frequency (8-14 Hz). Amplified Alpha brain waves are associated with several cognitive benefits, including:
In addition to raising Alpha brain waves, L-Theanine has been suggested to:
Stim L-Theanine enhances caffeine to promote calmer, cleaner stimulation that is precision-tuned for peak human performance.
Performance Lab® Stim Suntheanine® is 100% pure, nature-identical L-isomer-Theanine clinically shown to raise Alpha brainwaves. Suntheanine® is protected by 40+ nutritional technology patents. Stim’s 100 mg Suntheanine® supplies L-Theanine equivalent to what is found in 10 cups of green tea.
Caffeine works by blocking adenosine, a depressant hormone that signals for fatigue and drowsiness. This initiates a cascade of stimulatory catecholamine neurotransmitters that produce caffeine’s familiar psychostimulant effects:
Concern: Caffeine stimulation increases demand on catecholamines. Low catecholamine levels are linked with attention problems, mood imbalance, short-term crashing and long-range exhaustion.
L-Tyrosine helps by supporting the synthesis and recycling of catecholamine neurotransmitters that are most impacted by caffeine.
L-Tyrosine also enhances caffeine stimulation with research-backed cognitive benefits for:
These benefits appear to be more pronounced in challenging scenarios like sleep deprivation and overwork – matching well with many caffeine users’ needs.
Stim L-Tyrosine restores caffeine-depleted neurotransmitters, regulates caffeine triggered stress hormones, and supports clarity during chaos, distraction and fatigue.
Performance Lab® Stim Ajipure® L-Tyrosine uses patented, eco-friendly Ferment-A-Pure technology to turn non-GMO and gluten free vegetable-derived carbohydrates into clean, bioavailable amino acids.
Caffeine’s diuretic effect may accelerate excretion of some vitamins and minerals. In one study, researchers linked coffee consumption with mild reductions in B-Vitamins Riboflavin, B6, Folate and B12:
Concern: Caffeine may deplete essential B-Vitamins that support the healthy nervous system function, energy metabolism, and brain chemicals that drive a peak-performing stimulated state:
Stim counterbalances caffeine depletion with Vitamins B9, B6, B2 and B12 as high-absorption NutriGenesis®.
Stim can help anyone seeking to enhance their overall performance and life vitality in a healthier way than traditional stimulants.
Take 1 capsule for stimulation. Taken as directed, Stim’s 50 mg caffeine serving size is effective for most. Those with greater tolerance or a higher optimal caffeine dose may take additional Stim NutriCaps® in 50 mg caffeine increments up to 250 mg (5 NutriCaps®) per day, due to the formula’s scalable design.
Like all Performance Lab® supplements, Stim is designed to be safe for long-term daily use. Stim achieves this with advanced formulation and stacking strategies that actually enhance caffeine, for safer, better-tolerated stimulant activity along with superior performance-enhancing stimulant benefits. Stim’s clean design – free of GMOs, gluten, soy, colorants, preservatives and other additives – is also well-tolerated by the body; safe and beneficial for long-term use.
Yes. Stim is a safe, natural and 100% legal way to stimulate both body and mind.
More is not always better. High doses of caffeine can be counterproductive for human performance, triggering side effects that can make you shaky, irritable and unbalanced. Performance Lab® Stim’s 50 mg of caffeine per serving is conservative by design, supplying equivalent caffeine between a cup of green tea and a cup of coffee. With this approach, Stim helps you identify and manage your own optimal caffeine dose for superior performance benefits, whether you are taking it on its own or stacked with other caffeine sources.
NutriGenesis® is a Performance Lab® nutrition technology innovation: Vitamins, minerals and amino acids grown in live cultures at our state-of-the-art lab.
A true biological nutrient form, NutriGenesis® closely mirrors the molecular structure of food nutrients. NutriGenesis® nutrients offer significant advantages over standard nutrient forms.
Featured in several Performance Lab® formulas, NutriGenesis® vitamins, minerals and amino acids are bioengineered to be safe, active and highly effective for overall health and performance.
Vitamins, minerals and amino acids are the most important nutrients you need to build a strong foundation for health and performance.
Performance Lab® developed NutriGenesis® to have our own in-house vitamins, minerals and amino acids to use in our own nutritional supplements.
In producing NutriGenesis®, Performance Lab® can best maintain our industry-leading quality standards for cleanliness, purity, effectiveness and eco-friendliness, across all our ultramodern formulas.
Not all vitamins, minerals and amino acids are the same. There are many nutrient forms, produced with a variety of processes. Some of the most popular nutrient forms available in supplements today include:
Whole food vitamin and mineral supplements are sourced from fruits, vegetables, herbs and mushrooms. They include natural cofactors that make food nutrients so easy for the body to absorb and utilize. However, they do require extensive processing and may be made with GMOs, mass agriculture and dirty eco-destructive practices.
Isolated Chemical (USP) is the cheapest vitamin and mineral form found in the most basic multivitamin supplements. This synthetic form chemically alters vitamins and minerals, isolating them from their whole-food cofactors. As a result, Isolated Chemical (USP) nutrients are typically harder to absorb and less effective than whole food nutrients.
In this process, a mineral nutrient (such as iron, calcium, zinc) is bound with a chelator: An organic molecule (often an amino acid) that is large enough to enrobe the mineral. By surrounding the mineral, the chelator protects it against degradation. Chelated nutrients are highly stable and may improve nutrient uptake and utilization.
NutriGenesis® is different from traditional nutrient forms: Bioengineered to be better.
NutriGenesis® are cultured nutrients that replicate the creation of vitamins, minerals and aminos in nature.
NutriGenesis® is based on the work of Nobel Prize-winning physiologist Albert Szent Gyorgy, who theorized that nutrients presented in their naturally grown forms supply cofactors that make them more bioavailable, biologically active and effective than nutrients that are isolated.
In the NutriGenesis® process, single-cell organisms (Lactobacillus probiotics and brewer’s yeast) are seeded with micronutrients in a hydroponic growth medium.
The live single-cell organisms “eat” the micronutrients, divide and thrive. As the cultures grow, they produce fresh new NutriGenesis® vitamins, minerals and aminos within a matrix of natural cofactors. This familiar structure is more easily absorbed and utilized by the body.More on the NutriGenesis® Process
NutriGenesis® is essentially food nutrition. Mirroring food nutrients molecule-by-molecule, our vitamins, minerals and aminos are presented in pure elemental form. Maximum nutrition: Nothing more, nothing less.
Enhanced effectiveness. Because NutriGenesis® nutrients are in food-matrix form, they are recognized by the body as nature-identical -- maximizing nutrient uptake, bioavailability and beneficial activity.
Patented and researched. The patented process behind NutriGenesis® has been shown in research to enhance nutrient absorption and retention (when compared to chemical isolates).
Cleaner and safer. NutriGenesis® is produced in a sterile, tightly controlled lab setting. NutriGenesis® is minimally processed, requiring no pesticides, herbicides or other synthetics associated with some other whole-food nutrients.
Better for the planet: The NutriGenesis® process is clean and efficient, with little carbon footprint or environmental impact – especially when compared to factory farming for phytonutrients and strip mining for minerals.
It all begins with NutriGenesis® Multi for Men and Multi for Women: Performance Lab®’s multivitamin starting point for human performance optimization.
NutriGenesis® vitamins, minerals and amino acids are also found in Performance Lab® formulas Stim, Flex, BCAA, Pre, Post and Maintain.
Beyond Performance Lab®, NutriGenesis® B-Vitamins are found in Mind Lab Pro®: the Universal Nootropic™.
