Fall Asleep Faster, Sleep Deeper, Wake Refreshed

Sleep by Dr Brad is a carefully crafted blend of melatonin, magnesium glycinate, and glycine to help you fall asleep faster, sleep deeply, and wake up refreshed. Each ingredient in the formula plays a unique role in supporting better sleep, backed by scientific research. Here’s how they work:

Gentle Melatonin (300 mcg)

Reset Your Sleep-Wake Cycle Naturally

Melatonin is the body’s natural “sleep hormone.” Meta-analyses of clinical trials show that melatonin can help people fall asleep faster [1] and improve overall sleep quality [2].

But most supplements get the dosage wrong. You will often see 3,000 mcg (3mg) or even 5,000 mcg (5mg) capsules on the shelf. While these might knock you out, they flood your receptors with up to 100 times more hormone than you actually need. Dr. Brad takes a different approach, basing the dosage on human physiology rather than marketing.

The Science of Micro-Dosing
Each night, your body naturally produces around 20–35 mcg of melatonin to signal that it's time for sleep [3, 4]. This small amount is all it takes to initiate your body's natural sleep process. But only about 15% of oral melatonin actually reaches your bloodstream [5]. The rest is broken down by your liver before it can do its job.

That's why Sleep by Dr Brad contains just 300 mcg of melatonin. When you account for absorption, this delivers approximately 45 mcg of active melatonin—enough to restore your levels to the healthy physiological range without overwhelming your system.

Why not just take more?
In a landmark MIT study, researchers compared doses of 0.1 mg, 0.3 mg, and 3.0 mg in adults over 50 with sleep difficulties [6]. The results were clear: the 0.3 mg (300 mcg) dose restored sleep efficiency and raised melatonin to normal nighttime levels. The higher 3.0 mg dose also improved sleep—but it induced hypothermia and kept melatonin levels elevated well into daylight hours, disrupting the body's natural rhythm.

A separate study in healthy young adults found that 0.3 mg of melatonin significantly reduced sleep onset latency without causing any "hangover effects" the next morning [7]. Higher doses have been associated with morning grogginess and receptor desensitization—meaning you may need more and more to get the same effect [8].

By working with your body's natural physiology rather than against it, 300 mcg provides effective sleep support without the side effects of mega-doses.

Magnesium Glycinate (126 mg elemental)

Highly Absorbable Magnesium for Sleep

Magnesium is an essential mineral that supports relaxation and healthy sleep. Dr Brad included 126 mg of elemental magnesium in the glycinate form. Magnesium glycinate is magnesium bound to the amino acid glycine, making it highly absorbable and easy on the stomach (it avoids the laxative effect some other forms can cause).

In an 8-week placebo-controlled trial with elderly insomniacs, those who took 500 mg of magnesium nightly had significantly longer sleep time, higher sleep efficiency, and shorter time to fall asleep compared to those taking a placebo [9]. A 2021 systematic review and meta-analysis also found that magnesium supplementation reduced the time it takes to fall asleep by about 17 minutes in older adults with poor sleep [10].

Glycine (2,500 mg)

The Sleep-Supporting Amino Acid

Glycine is a naturally occurring amino acid that has been studied in several human trials for its impact on sleep. It has calming neuromodulator effects and helps lower core body temperature at bedtime, which together promote better sleep architecture.

Three randomized controlled trials have demonstrated that taking 3 grams of glycine before bed can improve sleep quality, reduce time to fall asleep, and reduce fatigue the next day – all without sedative side effects [11][12][13]. Dr Brad includes a substantial 2,500 mg dose of glycine to help you fall asleep more easily, sleep deeper, and wake up with greater energy and mental clarity.

Clean, Natural, and Blue

• No artificial colors or dyes – We use natural blue spirulina for a calming bluish hue, reminiscent of the night sky.
• No titanium dioxide – A synthetic colorant often used in supplements, but not here.
• Plant-based – Made from plant-based materials with no genetically modified ingredients.
• No unnecessary fillers – Every ingredient has a purpose. No fluff.
• Non-habit-forming – Gentle enough for nightly use without causing dependency.
