It is ideal for adults who prefer a natural, non-habit-forming sleep aid without the grogginess often associated with traditional sleep medications.
What sets this product apart is its liposomal technology, which encapsulates the nutrients for enhanced absorption and stomach gentleness. The blueberry flavor is sugar-free and pleasant, making daily intake easy. Users can adjust the dose: 2 mL for a 1.5g glycine serving or 4 mL for a full 3g dose.
