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

DO QUANTUM PRODUCTS CONTAIN HYDROGENATED OIL, FLAVORING ADDITIVES, ARTIFICIAL COLORS, OR FRAGRANCE?

No, we do not use hydrogenated oils, nor do we use any additives that alter the flavor, color, or fragrance of the product. Our products are also made without:

Added preservatives like potassium sorbate
Non-nutritive excipients like magnesium stearate
Talcum powder, an anti-clumping powder and suspected carcinogen

WHAT ARE EXCIPIENTS?

Excipients are binders, fillers, and "glues" that are added to many supplements to prevent clumping of powdered ingredients and improve efficiency in manufacturing. Typically, excipients do not have nutritional value and their ingestion can cause adverse effects, toxicity, allergic responses, and drug interactions.

At Quantum Nutrition Labs, we do not use any non-nutritive excipients in the manufacturing of our products. Our products are designed to provide pure, clean nutritional supplementation without any toxic tagalongs that can harm the body.

Quantum Nutrition Labs offers capsules, powders, and liquid supplements, but not tablets. This is because tablets almost always require non-nutritive binding agents to manufacture. When you choose a Quantum Nutrition product, you can be assured that its contents are pure.

WHAT MAKES D3 GOLD DIFFERENT FROM OTHER VITAMIN D3 SUPPLEMENTS?

Our expertly crafted Vitamin D3 Gold is a cleaner, more effective option compared to other vitamin D3 supplements in a few ways:

We use a natural source of vitamin D3 that does not contain common allergens like peanut or soybean oil.
We do not use any chemical additives such as added coloring agents, flavors, or magnesium stearate.
Vitamin D3 Gold is delivered in a fat-soluble base (extra virgin olive oil) for improved absorption.
Vitamin D3 Gold provides 1,000 mg of vitamin D3 in a single drop.

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 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.
