Momentous Sleep Guide: Nightly Sleep, Elite Sleep and Magnesium L-Threonate

Momentous draws a clear line between a melatonin-free product for nightly use and a melatonin product meant for short stretches. That distinction is the most useful thing to understand before buying.

Product details below are summarized from Momentous’s own product pages (checked Oct 18, 2026). Where I describe what a product is “for,” that is Momentous’s stated positioning, not my claim.

The key difference

Nightly Sleep has no melatonin; Momentous describes it as non-habit forming and designed for nightly use.
Elite Sleep contains 3 mg melatonin, and Momentous says it is for short-term use such as travel or schedule changes, not daily long-term use.
Magnesium L-Threonate is a single-ingredient option using Magtein®.

Don’t stack sleep products without checking with your doctor first; Momentous also advises consulting a healthcare professional before combining Nightly Sleep with other sleep aids. Ongoing trouble sleeping is worth a conversation with a doctor, not just a new supplement.
