Questions we actually get asked
Straight answers about the science, the ingredients, and what to expect — no fluff.
Melatonin is a clock signal, not a sleep aid. It tells your body what time it is — it doesn't help you fall into deep sleep, stay asleep, or wake up restored. Taking melatonin nightly can also suppress your body's natural production over time.
Sleep Club works downstream — targeting the nervous system activity, body temperature, and mental noise that actually prevent quality sleep.
Magnesium glycinate is the most bioavailable form of magnesium. It activates GABA receptors — the neurotransmitter system that calms neural activity and signals to your nervous system that it's safe to rest.
Most adults are magnesium deficient, and the wired tension that keeps people awake is often directly tied to this.
No. None of the three ingredients are habit-forming. Magnesium glycinate, glycine, and L-Theanine are naturally occurring compounds that support your body's own sleep mechanisms rather than replacing them.
Physician-designed. Built from the ground up by a practicing MD — not a standard contract manufacturer's stack.
No melatonin. We address the biological processes that determine how deeply and continuously you sleep.
Full transparency. No proprietary blends. No hidden doses.
Yes. Every batch is independently tested for purity, potency, and the absence of contaminants before it reaches you. Certificates of Analysis are available on request.
Sleep Club is made in the USA in an FDA-registered, cGMP-certified facility following current Good Manufacturing Practice standards.
The ingredients are well-tolerated by most people, but we always recommend consulting your physician before starting any supplement — especially if you are pregnant, nursing, managing a chronic condition, or taking prescription medications.

Take Sleep Club 30–60 minutes before bed. This gives the ingredients time to initiate the GABA and alpha-wave activity that precede sleep, and allows glycine to begin the temperature drop your body needs.
Follow the dosage on the label.
Many people notice a meaningful difference in how they feel in the morning within the first week. The full effect becomes clear at the 2–4 week mark. This isn't a one-night fix — it's a foundation.
Sleep Club is compatible with most supplement routines. Start with one new supplement at a time, give it two weeks, then add the next — so you understand what's working.
