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.

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.

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.

QNL was created by Dr. Robert Marshall, Ph.D., CCN, who practiced clinical nutrition for more than 30 years and hosted “HealthLine Now,” a radio show that helped listeners with their health and wellness goals. His whole foods approach to dietary supplementation, which included avoiding nonnutritive excipients and other common, commercially used additives, were, and still are, the foundation of our clean, high-quality, wellness products.

The philosophy behind our “quantum” approach to nutrition is that all living organisms possess a bioenergetic field that transcends physical matter. This biofield can be invigorated by whole food nutrients and phytochemicals that support the body's bioenergetic field, cellular health, and overall functioning. By exclusively utilizing the purest natural ingredients to create our products, Quantum Nutrition Labs aims to harmonize your body with the natural world and help you live your healthiest, most vibrant life.
