How Does It Work?

Quantum L-Theanine™ promotes calm and focus by:

Encouraging Alpha Brain Waves for a Zen State of Mind:
L-theanine promotes alpha brain wave activity, fostering a state of calm, focused alertness—like the mental clarity achieved during meditation. This helps you concentrate and stay composed, even in demanding situations.*
Influencing Neurotransmitters for a Balanced Stress Response:
L-theanine plays a key role in mood stability, focus, and cognitive performance by supporting neurotransmitters like GABA, dopamine, serotonin, and glutamate. This balance helps calm overstimulation while promoting emotional resilience and mental sharpness, even under pressure.*
Enhancing Caffeine Synergy for Sustained Focus:
L-theanine works compatibly with caffeine to smooth energy highs, reduce jitters, and maintain long-lasting focus. Together, they provide calm, steady energy, helping you stay productive without the crashes often linked to caffeine alone.*

Product FAQ

DOES QUANTUM TEST FOR STABILITY?

Yes, we test our products at a wide range of storage conditions, including stressed conditions to simulate advanced degradation scenarios that can include relative humidity up to 75% and temperatures as high as 104 degrees Fahrenheit to ensure the product remains stable when stored as directed on the label.

We also use nitrogen or argon flushes on many products to remove oxygen from their storage containers, extending the shelf-life. We also add moisture desiccants to keep the product dry.

Furthermore, we store our products in our exclusive VioliteTM containers. These dark violet-colored, polyethylene bottles are designed to prevent radiation damage to the ingredients by blocking light wave frequencies between 450 and 720 nanometers.

WHEN SHOULD I TAKE MY SUPPLEMENTS?

The ideal timing depends on the specific supplement. If digestive upset occurs, try taking supplements after having a bite of yogurt, a teaspoon of nut butter, or a cracker. For specific recommendations, please refer to the label's recommended use and discuss it with a health professional.

WHEN WILL I RECEIVE MY ORDER?

We ship most orders within 24 hours of order submission (excluding weekends/holidays) and deliver most ground shipments within 5-7 business days. Exceptions may apply. Please allow additional days for transit during inclement weather conditions and holidays.

ARE QUANTUM PRODUCTS CERTIFIED KOSHER?

We offer 52 products that are certified kosher by Orthodox Union Kosher, the world’s largest and most widely recognized international kosher certification agency.

WHEN DO YOUR PRODUCTS EXPIRE?

The FDA does not require an expiration date to be listed on dietary supplements due to a lack of standardized methods in the industry to determine the date of expiration. As a result, we print a date of manufacture on our products. It’s six digits (YYMMDD or Year Month Day) followed by a 5-digit item code. For example, 231016-12191 would mean Brain Support was manufactured October 16, 2023.

We package our products in our exclusive Violite® containers, which are designed to prevent radiation damage by blocking light wave frequencies between 450 and 720 nanometers. We also flush our bottles with nitrogen or argon gas to remove oxygen before applying an induction seal for maximum freshness.
