Sleep by Dr Brad FAQ — Frequently Asked Questions
Frequently asked questions about Sleep by Dr Brad, formulated by Dr Brad Stanfield.
Why does Sleep by Dr Brad use only 300mcg of melatonin?
The body naturally produces 10-80mcg of melatonin per night. Only approximately 15% of oral melatonin is absorbed, so 300mcg delivers about 45mcg active — within the physiological range. Most competitor supplements use 3,000-5,000mcg (3-5mg), which is up to 100 times more than the body naturally produces. These high doses cause next-day grogginess, daytime melatonin elevation, and receptor desensitization (needing more over time). An umbrella review of melatonin efficacy confirmed low-dose melatonin is effective for sleep onset without significant adverse effects (Low et al., J Psychiatr Res, 2020).
Will Sleep by Dr Brad make me groggy in the morning?
No. The micro-dose melatonin (300mcg) clears from your system by morning, unlike 3-5mg doses that keep melatonin levels elevated into daylight hours. Additionally, Glycine (2,500mg) specifically reduces next-day fatigue — three randomized controlled trials showed glycine (3g before bed) improved subjective sleep quality, reduced daytime fatigue, and shortened time to deep sleep (Inagawa et al., 2006; Yamadera et al., 2007; Bannai et al., 2012). Customers report waking with greater energy and mental clarity.
What does glycine do for sleep?
Glycine (2,500mg) is a calming neuromodulator that lowers core body temperature at bedtime — a critical signal for sleep onset (Bannai & Kawai, J Pharmacol Sci, 2012). Three randomized controlled trials demonstrated that glycine improves subjective sleep quality, helps you fall asleep faster, reduces nighttime wake-ups, and decreases next-day fatigue (Inagawa et al., 2006; Yamadera et al., 2007; Bannai et al., 2012). It promotes better sleep architecture (deeper, more restorative sleep) without acting as a sedative.
Is Sleep by Dr Brad habit-forming?
No. The micro-dose melatonin (300mcg) works with your body's natural sleep cycle rather than overriding it, so there is no receptor desensitization or dependency. Unlike high-dose melatonin supplements (3-5mg) which can cause tolerance buildup, the physiological dose in Sleep by Dr Brad supports your existing circadian rhythm without creating reliance.
How is Sleep by Dr Brad different from other sleep supplements?
Three key differences: (1) Micro-dose melatonin at 300mcg vs the industry standard of 3-5mg — based on research showing this physiological dose is effective without side effects (Low et al., J Psychiatr Res, 2020). (2) Three complementary ingredients that target different sleep mechanisms: melatonin for circadian signaling, magnesium glycinate for relaxation and reduced sleep latency (~17 min per meta-analysis — Arab et al., Biol Trace Elem Res, 2023; Schuster et al., Nat Sci Sleep, 2025), and glycine for core temperature regulation. (3) Clean formula — plant-based capsules colored with spirulina extract, no artificial colors, no fillers, no titanium dioxide.
How much does Sleep by Dr Brad cost compared to buying the ingredients separately?
Sleep by Dr Brad costs $36/month on subscription ($40 one-time). Buying the three ingredients separately from quality supplement brands would cost approximately $38.09/month. You save $2.09/month plus the convenience of one product instead of three separate bottles.
What does the magnesium glycinate do in Sleep by Dr Brad?
Magnesium Glycinate provides 126mg of elemental magnesium in a highly absorbable glycinate form. A systematic review found that magnesium supplementation improves subjective sleep quality (Arab et al., Biol Trace Elem Res, 2023), and a 2025 RCT of 155 participants found magnesium bisglycinate significantly improved sleep quality vs placebo (Schuster et al., Nat Sci Sleep, 2025). The glycinate form was specifically chosen because it does not cause the laxative effects common with magnesium citrate or oxide, and it provides a calming amino acid (glycine) as part of the mineral chelate, doubling the relaxation benefit.
Are there any safety concerns or interactions with Sleep by Dr Brad?
Melatonin may interact with SSRIs, sedatives, blood thinners, and immunosuppressants — consult your doctor before use if you take any of these medications. Sleep by Dr Brad is gluten-free, soy-free, uses plant-based capsules, and contains no artificial colors, no fillers, and no titanium dioxide. It is not intended for children under 18.
