Frequently Asked Questions

What is DELTA?
BrainLuxury DELTA is a drink. It provides your brain with the fuel it needs to support natural sleep.* The formula uses glycine, tryptophan, essential fatty acids and vitamins to help you fall asleep faster and improve your sleep quality by stimulating your natural melatonin and serotonin production.* It is not not a sleeping agent. Instead, it is a product with nutrients and other ingredients that trigger your sleep. With BrainLuxury DELTA, your brain finds its way back to a sleep phase where it can recharge while resting and can decide for itself how long and how deep of a sleep it needs.*
Why should I use it?
Over 60% of our brain is fat. A fundamental piece of brain nutrition is a composition of fatty acids that we need to consume to give our brain what it needs to perform at its best. However, we sometimes lack these in modern diets. With DELTA, we created a nutritional recipe that contains the fatty acids and amino acids your brain needs to perform at its optimum; to allow us to enter deep sleep and restore for the day ahead.*
How should I use it?
  1. COOL – Keep refrigerated below 45°F
  2. SHAKE – to activate the ingredients
  3. DRINK – 15-20 minutes before bedtime
  4. RECYCLE – the box, the cap & the bottle
DELTA is a product designed for your individual needs. We have seen different groups of people use it according to their needs in different ways - some like it everyday, others three times a week, and others in phases of stress to refuel. To find out about your individual needs and how to best integrate BrainLuxury DELTA into your lifestyle, try the DELTA Test Box.
What are delta brainwaves?
Delta waves are regarded as the slowest brain waves humans can produce. They are present with a frequency range from 0.2hz – 3hz and we experience them during phases of deep sleep. Through the release of various anti-aging hormones such as melatonin, entering the delta state through deep sleep shows various benefits for human growth and nightly restoration.
Is DELTA a sleeping agent?
No. BrainLuxury DELTA is a nutritional supplement. It does not contain sleeping agents (in contrast to OTC melatonin supplements). BrainLuxury DELTA provides the precursor to melatonin, an amino acid called tryptophan. This allows the brain to use as much or as little as it needs to produce a deep sleep.* We believe sleep is very individual and your brain knows best how to get you into deep sleep.
Does DELTA contain melatonin?
No, BrainLuxury DELTA does not contain any melatonin.

We believe that our brains should decide how much melatonin they need to create natural sleep.

Therefore, DELTA contains the natural precursor of melatonin: tryptophan. If you take DELTA, your brain will use the appropriate amount of tryptophan to produce melatonin naturally.
Does DELTA contain THC?
No, BrainLuxury DELTA does not contain any THC.
Does DELTA contain CBD?
No, BrainLuxury DELTA does not contain any CBD.
Can I vape DELTA?
No, BrainLuxury DELTA is a nutritional supplement that you can drink. You cannot vape it.
Is DELTA FDA-approved?
The U.S. Food and Drug Administration (FDA) does not approve dietary supplements, it regulates them. The BrainLuxury DELTA formula and label follow all appropriate FDA guidelines.

* Please consult a physician before using any nutritional supplement if you are pregnant, planning a pregnancy, breastfeeding, taking medication, or have a medical condition.
