Capsule #2: Magnesium

Magnesium Glycinate supports sleep by promoting muscle relaxation and neuromuscular function, helping to calm the body and mind for easier, deeper sleep, and, as part of the melatonin–L-theanine blend, it also aids energy production and reduces daytime fatigue, supporting overall recovery and well-being; the supplement delivers a highly bioavailable, gentle form of magnesium with 133 mg of elemental magnesium per serving to support daily relaxation and recovery, assist with muscle relaxation and neuromuscular function (beneficial for muscle tension and occasional cramps), promote a calm mood and restful sleep, and since magnesium is essential for heart and bone health and contributes to energy production to help reduce fatigue; the capsule is easy on the stomach and contains no artificial colors or flavors, and is made without dairy, wheat, soy, peanuts, tree nuts, eggs, shellfish, sesame, or fish.†

Capsule #3: Theanine

Theanine promotes a calm, relaxed mind by supporting GABA, serotonin, and dopamine activity without causing sedation, helping you unwind and ease into sleep, and when used in the Sleep Support pack it works with melatonin and magnesium to support faster sleep onset and deeper, more restorative rest as part of your personalized nightly routine. The Supplement Details note that it provides 100 mg of L-theanine—the naturally occurring amino acid found in green tea—to support calm focus, stress resilience, and a balanced mood, and that, known for promoting relaxation without sedation, theanine supports healthy neurotransmitter activity, including GABA, serotonin, and dopamine, which can help with mental clarity and may support more restful sleep; it’s also commonly used to smooth the effects of caffeine and support overall cognitive and cardiovascular wellness as part of a daily routine. This clean, well-tolerated formula contains no common allergens and is made without dairy, wheat, soy, peanuts, tree nuts, eggs, shellfish, sesame, or fish.†
