Product FAQ
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.

ARE THERE SUPPLEMENTS THAT CAN HELP ME SLEEP?
Clinical evidence supports the use of several different supplements for promoting restful sleep. These include:

  • Melatonin. This sleep-promoting hormone is naturally released by the body in the hours leading up to bedtime. Melatonin supplementation may help support a healthy sleep-wake cycle especially when you’re trying to realign your natural sleep rhythm due to shift work or jet lag. However, it’s important to use melatonin cautiously as scientists lack information on its long-term effects.
  • Magnesium. Magnesium deficiency is increasingly common and may cause nighttime symptoms like leg cramps. Easy for the body to absorb, magnesium glycinate is known for its calming properties and may promote relaxation and sleep. Research indicates that supplementing with magnesium may help some individuals fall asleep faster and stay asleep longer.
  • Lavender (Lavandula angustifolia). Essential oil components of English lavender, like linalool and terpineol, support sleep by reducing stress and activity in the central nervous system, lowering blood pressure, and potentially improving mood. Lavender has a long history of use in natural medicine for its calming properties and possesses limited risk for side effects. Lavender oil can be taken by mouth or administered through aromatherapy.
  • Valerian (Valeriana officinalis). This root extract contains many bioactive chemicals that can have moderate sedative and relaxing effects on the body. A possible mechanism by which valerian may improve sleep is by increasing the amount of gamma-aminobutyric acid (GABA), a calming neurochemical in the brain.11 Some studies have shown valerian to help people fall asleep faster and sleep more throughout the night.
  • L-theanine. An amino acid found in tea leaves, L-theanine is another substance that triggers the release of GABA.12 L-theanine naturally calms anxiety, enhances relaxation, and provides a safe natural sleep aid without drowsiness.13 L-theanine should be used carefully as it can interact with other medications.

WHERE ARE QUANTUM SUPPLEMENT INGREDIENTS SOURCED?
Quantum Nutrition Labs (QNL) meticulously sources all of its ingredients, accepting only those that meet the highest quality standards for identity, purity, strength, and composition. We strive to procure sustainably produced botanicals and innovative nutrient blends to deliver the best, most bioavailable ingredients for each of our products.

Once received, all raw materials are held in a 10-day quarantine for an in-depth inspection. We test samples from every shipment lot in our state-of-the-art, USP-certified laboratory. After ingredients are proven to be safe, pure, and free of contaminants, they are moved into the manufacturing phase of supplement development.

MY ORDER ARRIVED AND THE CAPSULES LOOK DIFFERENT THAN LAST TIME.
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.
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 HAVE ANY MENOPAUSE-SUPPORT SUPPLEMENTS?

  • Libifem®. This fenugreek seed extract is clinically proven to support sexual health and promote menopausal comfort.*
  • LJ100®. Our Tongkat Ali ingredient is sourced from LJ100™, a standardized root extract of Eurycoma longifolia which consistently delivers evidence-based potency. Tongkat Ali root has a long history of safe use as a natural option for improving testosterone levels and supporting reproductive health.*
