## Overview

Sierra Life Sciences 120 mg Melatonin Capsules deliver a high potency, vegan, and Non-GMO sleep aid designed to support healthy circadian rhythms disrupted by modern lifestyle factors like screen exposure and travel.

## Description

Sierra Life Sciences Melatonin Capsules are designed for adults seeking reliable sleep support as part of a consistent nighttime routine. The easy-to-swallow capsule format fits seamlessly into daily habits and supports a healthy sleep-wake cycle when occasional late nights, travel, or schedule changes disrupt normal rhythms. Modern lifestyles often interfere with the body’s natural melatonin production. Evening exposure to screens, artificial lighting, and irregular schedules can make it harder to unwind at night. Establishing a calming bedtime routine—paired with a clean, straightforward melatonin supplement—can help signal the body that it’s time to rest. Manufactured in the USA in a cGMP-certified facility using Non-GMO ingredients, Sierra Life Sciences Melatonin Capsules offer a simple, dependable option for customers who prefer a clean-label sleep supplement focused on nightly consistency and overall sleep quality.

Review: Sticky finger Bottles.. - Yes. They do work and help you get a good nights rest. Only thing is when you get two bottles the bottles are sticky. Like stick to your fingers. Why? Don’t know. If they can improve the battles, not to stick your fingers when you open them. They are a great product, but the sticky fingers not sure what that’s about…..? Hope they get this review and get rid of sticky finger bottles…
