Common questions
What's the best magnesium form for sleep?
Glycinate. Bound to the amino acid glycine, which also has sleep-supportive properties. Avoid oxide (poorly absorbed).
When should I take sleep supplements?
30–60 minutes before bed. Blend formulas (magnesium + herbs) work better together than stacked individually.
Are sleep supplements habit-forming?
Glycinate, valerian, passionflower — no. Melatonin at high doses can be mildly habit-disrupting. Most practitioners recommend glycinate-led blends.
