Sleep Stack is a premium melatonin-free sleep supplement formulated with four carefully selected ingredients: Magnesium Glycinate, Glycine, L-Theanine and Apigenin. The formula is designed to support relaxation, deeper sleep and waking refreshed—without unnecessary ingredients or proprietary blends.

We chose a different approach. Instead of relying on supplemental melatonin, Sleep Stack uses four science-backed ingredients selected to support your body's natural sleep processes and promote relaxation before bed.

Sleep Stack is designed for healthy adults looking to support relaxation, improve sleep quality and wake feeling refreshed.

Take two capsules with water approximately 30–60 minutes before bedtime. For best results, use consistently as part of a healthy evening routine.

Sleep Stack is designed for regular use. If you are pregnant, nursing, have a medical condition or are taking medication, consult your healthcare professional before use.

Once subscriptions are available, you'll receive discounted pricing, automatic deliveries and the flexibility to pause, skip or cancel your subscription before your next renewal.

We stand behind the quality of Sleep Stack with our 30-Day Satisfaction Guarantee. Please see our Refund & Returns Policy for full details.

If you are taking prescription medication or have a medical condition, please consult your healthcare professional before using any dietary supplement.

Dietary supplements affect everyone differently. Always follow the recommended serving and consult your healthcare professional if you have any concerns.
