Main highlights
- Tranquil Nights Ahead - Vegan melatonin reinforces your calming sleep routines. Serene nights await, thanks to GABA and Chamomile, alongside Valerian root 10:1 extract that’s 10 times more potent than our previous blend.
- Sleep Like You Mean It - We've improved the formula of our melatonin capsules for adults seeking a non-habit-forming way to get their well-deserved rest and feel ready to take on their day in the morning.
- Packaging Update: We’ve updated our product label to reflect a revised mg-per-serving amount (from 2915 mg to 1115 mg). Please note: the ingredients, formula, serving size, and supplement facts have not changed. You may receive either label during this transition period — both versions are authentic and reflect the same high-quality product.
- Ingredients of Your Dreams - Our sleep aid supplement contains 5mg of melatonin, 500mg of Magnesium Glycinate, Ashwagandha, and Black Pepper extracts. It's a nightly routine that leaves you energized every morning.
- Benefits You Can Feel – L-Theanine is known to encourage alpha brain wave activity, often linked with calmness. Magnesium glycinate is a gentle, bioavailable form of magnesium that helps support relaxation as part of a nighttime routine.
