Experience a melatonin-free path to more peaceful nights with Sports Research Sleep Complex. This vegan capsule formula is designed to support a calm transition from daytime to rest, without the daytime drowsiness sometimes linked to melatonin-heavy products. The blend harmonizes botanicals with targeted amino acids to create a foundation for deeper rest and a refreshed morning start.
What’s inside is a thoughtful 5-in-1 synergy. Each serving includes multiple Magnesium forms for comfortable relaxation, Valerian Root standardized to 2% Valerenic Acid, 200 mg L-Theanine, 125 mg GABA, and 100 mg 5-HTP. The combination is crafted to help ease the mind and soften bodily tension, supporting a smoother sleep onset and improved overall sleep quality as part of a regular routine.
In real-life terms, this means you might notice a calmer wind-down after a busy day, quicker onset of sleep, and a more restorative feel upon waking. The formula is positioned as a non-melatonin option that helps set the stage for satisfying rest, rather than promising guaranteed results.
Each bottle provides 30 servings, making it simple to incorporate into a nightly ritual. Use as part of a consistent sleep routine and pair with healthy evening habits for best results. If you have sleep concerns or plans for medication, consult a healthcare professional before starting supplementation.
