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.

Our vegetable capsules are made from tree fiber. Our Certificate of Analysis (CoA) verifies that no undesirable solvents are used to make our capsules. Solvent-free vegetable capsules offer superior digestibility and purity while providing beneficial fiber.

Vegetable capsules are a healthier alternative to solvent-tainted vegetable capsules, tablets, and animal-based gelatin capsules, all of which contain chemical preservatives and other contaminants.

We invite you to call us at 1-800-370-3447, email us at [email protected], or fill out the contact form available on our Contact Us page. Our customer service team is available to respond to inquiries Monday through Friday from 8:00 am to 6:00 pm (CST).

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.

We guarantee the quality and consistency of every supplement we offer by using cutting-edge testing equipment and practices and running multiple tests on each ingredient, including:

• Heavy metal testing
• Microbial testing for contaminants
• Microscopy to evaluate botanical identity
• High-performance thin layer chromatography, which looks at levels of active phytochemicals within a plant

At QNL, our rigorous testing protocols guarantee that our products are free from toxins, pesticides and herbicides, and steroid and antibiotic residues.

In addition to performing in-house testing, we engage numerous third parties to validate the quality of our products. Our manufacturing facility is certified by independent testing agencies like USP and NSF. Many of our products are further certified by the Non-GMO Project, OU Kosher, and USDA Organic.

Lastly, the vitality of the ingredients tested is screened using energetic assessment methods based on an applied kinesiology method known as the Bi-Digital O-Ring Test, developed by Dr. Yoshiaki Omura.1 This method has been an integral part of QNL’s ingredient sourcing and formulation development.

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.
