X1 Health introduces Deeper Sleep, an advanced proprietary evening formula developed in the United States to support relaxation and restful sleep, without melatonin, antihistamines or sugar. Featuring 11 active ingredients in its Chocolate formulation, including magnesium, glycine and L-theanine, Deeper Sleep's introduction explores research on selected ingredients, the limitations of commonly used sleep aids and the importance of informed choices, with product information and free early-access registration available at https://x1health.com.
LAS VEGAS, Nov. 5, 2026 /PRNewswire-PRWeb/ -- The search for better sleep raises another question: what are the consequences of taking a sleep aid night after night?
Research has linked greater cumulative use of strong anticholinergic medicines—a group that includes certain older antihistamines used for sleep—with increased dementia risk in older adults. The findings show an association, not proof that these medicines cause dementia.
Melatonin presents a different question. Although short-term use appears safe for most people, its long-term safety remains less understood.
For consumers comparing sleep supplements, these distinctions matter. So do the ingredients, doses and evidence behind other options.
X1 Health developed Deeper Sleep without melatonin or antihistamines, combining 11 active ingredients in an advanced proprietary evening formula. Its ingredients include magnesium, glycine and L-theanine, each studied in human clinical research.
What have those studies found—and what can they actually tell consumers about sleep support?
Glycine: small human studies on sleep quality
Small studies using 3 grams of glycine before bedtime reported improvements in subjective sleep measures. A 2007 study by Yamadera and colleagues also reported shorter time to sleep onset.
Deeper Sleep Chocolate contains 3 grams per serving. The findings offer preliminary support for further research, rather than a guarantee of results.
Magnesium bisglycinate: a modest benefit in a recent trial
A 2025 randomized trial by Schuster and colleagues enrolled 155 adults reporting poor sleep. Four weeks of supplementation produced a modest improvement in self-reported insomnia severity compared with placebo.
The trial used 250 mg of elemental magnesium daily. Deeper Sleep Chocolate provides 110 mg, so the research does not establish the same benefit at the product's dose.
L-theanine: research on selected sleep measures
A 2019 randomized crossover trial by Hidese and colleagues studied 200 mg of L-theanine daily in 30 adults. Selected sleep-questionnaire measures improved compared with placebo, although the overall sleep-quality score did not show a statistically significant advantage.
Deeper Sleep Chocolate contains 200 mg per serving. These studies evaluated individual ingredients or specific preparations, not the finished Deeper Sleep formula; they do not establish the combination's effectiveness or long-term safety.
Looking beyond melatonin
Market data suggest interest in a broader range of ingredients. SPINS reported that magnesium dollar sales increased 22.8% while melatonin declined 2.7% within its combined sleep and calmative/mood-support categories during the 52 weeks ending October 4, 2026. These figures describe sales, not comparative effectiveness.
One evening powder, 11 active ingredients
Developed in the United States, Deeper Sleep is designed to support relaxation and restful sleep.*
The Chocolate formulation contains glycine, myo-inositol, magnesium bisglycinate, taurine, palmitoylethanolamide (PEA), ashwagandha extract, L-theanine, fermented GABA, phosphatidylserine, saffron extract and apigenin.
Each container provides 30 servings, with a 10-gram serving size. Chocolate and Mango are included in the launch plan.
Product information and early-access registration are available at https://x1health.com. Registration is free, with no payment or account required. It records interest, rather than a confirmed order or inventory guarantee.
Persistent sleep problems warrant professional assessment. Supplements can have side effects and interactions; excluding melatonin and antihistamines does not establish that a formula is safer or non-habit-forming.
