Anna covers sleep supplements, dosing, and safety. She cross-checks label claims against USP and NSF verification standards and published trials, with particular attention to interactions and the people who should avoid each product.
Every article goes through our editorial checklist: claims traced to published research or clinical guidelines, uncertainty stated plainly, and clear signposts for when professional care is the right next step. Read more on our About page.

The word 'magnesium' on a label hides a spectrum: glycinate absorbs well and calms, citrate absorbs well and loosens bowels, threo…
Sleep studies typically use 200–500 mg of elemental magnesium in the evening — but 'elemental' is the operative word, because labe…

GABA is the brain's main calming neurotransmitter, so swallowing it sounds logical — but whether oral GABA crosses the blood-brain…
5-HTP converts directly into serotonin — and from there into melatonin — giving it a real biochemical path to sleep. That same pat…
