About Algae Omega-3
Direct vegan source of DHA (and increasingly EPA). Bypasses ALA-to-DHA conversion, which is poor in most adults.
About Melatonin
Pineal-gland hormone that signals 'night-time' to the body. Most useful for jet lag and shifted sleep schedules; lower doses (0.3 mg) often work better than 5–10 mg.
