Melatonin 300 mcg
Life Extension provides the clinically recommended low-dose melatonin that many experts suggest is most effective for circadian rhythm regulation without next-day grogginess. Their commitment to COAs (Certificates of Analysis) for every batch sets them apart in the value segment.
Quality & Materials
Pharmaceutical grade melatonin in a 300mcg dose, which mimics the body's natural physiological production level.
Evidence & Testing
Melatonin's efficacy for jet lag and delayed sleep phase syndrome is backed by dozens of RCTs. The 300mcg dose was famously identified by MIT researchers as the optimal dose.
Brand Transparency
Life Extension offers a 'Certificate of Analysis' for every single product they sell, which can be looked up by lot number on their website.
Value Assessment
Extremely high value; a single bottle provides a 100-day supply for less than $10, making it the most cost-effective evidence-based sleep aid.
Why Not Alternatives?
Most 'extra strength' melatonin products (5mg-10mg) are significantly overdosed, leading to receptor desensitization and vivid nightmares. Life Extension avoids the 'more is better' marketing trap used by brands like Natrol or ZzzQuil.
