Each serving delivers 1g of **Glycine**, but the clinical research on sleep quality used 3g before bedtime — so you'd need to take three capsules to reach the studied dose. At that intake, you're right at the effective minimum for supporting sleep onset and reducing next-day fatigue.
Glycine also serves as a building block for collagen and plays a role in creatine synthesis, giving you potential relevance for skin and muscle support beyond sleep. The capsule form makes dosing flexible, which helps since individual needs vary.
The main tradeoff is pill burden. Getting to the 3g clinical dose means you're taking three capsules per night, which makes a powder format more practical at this dose level.
