The Chill Factor™ is a pharmaceutical-grade tool designed to help you reach a state of relaxed alertness, featuring 100mg of 100% pure Suntheanine®. Unlike generic L-Theanine, this patented version is clinically verified to cross the blood-brain barrier to neutralize stress-driven mental static without making you sleepy. It is the definitive choice for professionals who need to stay calm, sharp, and focused in high-pressure environments.

Why Suntheanine® is the Gold Standard
Not all L-Theanine is created equal. Most budget versions use a chemical synthesis that results in a mix of L and D-isomers, the latter of which can actually block the benefits of the L-form.

Feature Generic L-Theanine Suntheanine®
Production Method Chemical Synthesis Patented Enzymatic Fermentation
Isomer Purity Often contains D-Theanine 100% Pure L-Isomer
Blood-Brain Barrier Inconsistent absorption Verified Cross-Through
Clinical Validation Limited or extrapolated data 40+ Human Clinical Trials
Brain Wave Effect Minimal Alpha Induction Proven Alpha-1 Modulation

 

How to take it: For the best results, take one capsule daily — ideally 30–60 minutes before you need to be at your sharpest. It works best on an empty stomach for faster absorption.

Expert Tip: If you’re a coffee drinker, take The Chill Factor™ with your first cup. It smooths out the caffeine jitters, giving you a steady, calm focus without the usual stimulant crash.

• Pharmaceutical-Grade Sourcing: We utilize only 100% pure Suntheanine®, the most clinically researched form of L-Theanine globally.

• Isomeric Integrity: Our focus is on molecular purity. We ensure the exclusion of the inactive D-isomer, which can interfere with the biological activity of the L-form.

• Small-Batch Integrity: To prevent the degradation of bioactive amino acids, we manufacture in limited quantities. This ensures that the product you receive hasn't been sitting in a warehouse losing potency.

• Zero Fillers: We reject the use of synthetic flow agents, hidden binders, or artificial colors that can interfere with the rapid absorption of the nutrient.

What are the benefits of Suntheanine®?
• Suntheanine® is primarily used to promote a state of relaxed alertness. By increasing alpha brain wave activity, it helps neutralize the mental static caused by stress without making you feel sleepy. It is widely used to improve focus, reduce irritability, and smooth out the jitters often associated with caffeine.

Is Suntheanine® different than L-theanine?
• Yes, in terms of purity and consistency. While L-theanine is the general name for the amino acid, Suntheanine® is a patented, pharmaceutical-grade form produced through a specialized enzymatic process. Most generic L-theanine is chemically synthesized and can contain D-theanine, an inactive isomer that can actually block the absorption of the beneficial L-form. Suntheanine® is 100% pure L-isomer.

Who should not take Suntheanine®?
• While exceptionally safe, individuals taking medication for high blood pressure or stimulant medications for ADHD should consult their healthcare provider, as Suntheanine® can have a modulating effect on the cardiovascular system. It is not recommended for children, pregnant women, or nursing mothers without medical supervision.

What are the negative side effects of L-theanine?
• L-theanine is generally recognized as safe (GRAS) and has no known toxicity at standard doses. However, some users may experience mild headaches or a slight drop in blood pressure if they are already prone to hypotension. Because it promotes relaxation, taking it in extremely high doses alongside other sedatives is not recommended.

Can I take The Chill Factor™ every day?
• Yes. Suntheanine® does not lead to tolerance or dependence. It is a natural amino acid that the body processes efficiently, making it suitable for daily support in high-performance or high-stress environments.

How is Suntheanine® different from herbal relaxants like Valerian or Kava?
• Herbal relaxants often work as sedatives, which can cloud your thinking or cause brain fog. Suntheanine® is non-sedative; it works by shifting your brain waves into a focused flow state rather than just shutting down the nervous system.

On Alpha-Wave Modulation (Relaxed Alertness)This study demonstrates that a single dose of L-Theanine significantly enhancesalpha brain wave activity, which is indicative of a state of relaxation without causing drowsiness.

On Nootropic Synergy (Caffeine + Theanine)Research confirms that combining L-Theanine with caffeine improves cognitive performance, increases speed and accuracy on attention-switching tasks, and reduces the susceptibility to distracting information.

On Stress and Cardiovascular ResponseThis study specifically examined how L-Theanine reducespsychological and physiological stressresponses, such as heart rate and salivary immunoglobulin A (s-IgA), during difficult mental tasks.

• Alpha-Wave Modulation: This formula is specifically engineered to cross the blood-brain barrier within 30–60 minutes to promote the Alpha-1 brain wave state.

• Glutamate Modulation: Strategically dosed at 100mg to act as a gentle antagonist to glutamate receptors, helping to neutralize the noise of modern high-stress environments.

• Clean Energy Synergy: Designed to be taken as a standalone or paired with caffeine to smooth out the cardiovascular spike and jitters associated with stimulants.

• Bioavailability Priority: Utilizing a clean-label capsule to ensure rapid disintegration in the digestive tract for fast-acting mental calm.

• Non-Drowsy: Unlike herbal sedatives, Suntheanine® does not cause daytime sleepiness or impair cognitive function.

• Interactions: Consult with a healthcare professional if you are currently taking prescription medications for high blood pressure or stimulants.

• Pregnancy & Nursing: As with any supplement, consult your doctor before use if you are pregnant or breastfeeding.

• Adherence: Do not exceed the recommended daily dose unless directed by a medical professional.

• General Safety: For adult use only. Keep out of reach of children.
