Immune Support*

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.

The immune system is an incredibly complex network of organs, tissues, glands, and cells that find and respond to harmful foreign invaders like viruses and bacteria, which can cause disease. The immune system relies on various micronutrients, such vitamin A, vitamin C, vitamin D, vitamin E, selenium, beta-carotene, iron, and zinc, for optimal functioning. Deficiencies in these and other phytonutrients can lead to increased risk for infection and longer recovery periods.

Ideally, we would get all the essential immune-boosting vitamins and minerals we need by eating nutritious foods. However, it can be difficult to maintain a balanced diet for many reasons. Even if you consume a nutrient-rich diet, industrial farming practices have eroded the microbiome of the soil our food is grown in and with it the nutritional value of most food products. As a result, it's critical to take targeted supplements that support your immune system.

We source ingredients only in their unrefined state, so you may notice that the color, texture, and even odor of a product may vary somewhat between batches and across seasons. Despite these natural variations, each product contains its exact formula and is rigorously tested for purity.

Once your order is placed and you have received an order confirmation, we are unable to change your order to add or remove items. To purchase additional products, you will need to place a new order. You may cancel your order before shipment by calling 1-800-370-3447.

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.

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.

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.
