## Common Questions Answered on PUKO

- **Best magnesium form for sleep?** Magnesium glycinate chelate — bound to glycine (a calming amino acid) for superior absorption and a gentler GI profile than oxide or citrate.
- **Does tart cherry help sleep?** Yes — contains natural melatonin precursors (tryptophan, serotonin, small natural melatonin). Studied at concentrate-equivalent doses (Howatson et al., 2012).
- **Is KSM-66 better than regular ashwagandha?** KSM-66® is the most clinically studied full-spectrum ashwagandha extract, standardized to 5% withanolides.
- **What does phosphatidylserine do?** Supports neuronal communication, working memory, attention, and a healthy cortisol response under cognitive stress. Has an FDA-qualified health claim for cognitive function.
- **Why melatonin-free?** Melatonin is a hormone; supplementing it long-term may influence the body's own production. PUKO supports natural sleep mechanisms instead of overriding them.
- **Are there caffeine alternatives?** Guarana extract provides slow-release caffeine matrix-bound to tannins, producing a smoother energy curve than coffee or synthetic caffeine.
