Nello Supersleep earns its place as our #2 overall sleep pick. The ashwagandha and Maizinol saffron approach is genuinely innovative and fully melatonin-free, the formula is the cleanest we have reviewed, and the magnesium glycinate delivers noticeable improvements in sleep depth.

Our Nello Supersleep Review
Nello Supersleep has built a reputation for low-additive supplement formulations. The standout ingredients are KSM-66 ashwagandha and Maizinol, a standardized saffron extract, which support evening calm without any melatonin or the grogginess sometimes associated with hormonal sleep aids.
Nello Supersleep is best suited to users dealing with both sleep onset and sleep quality issues. The magnesium glycinate and L-glycine combination was particularly noticeable — deeper sleep, fewer nighttime awakenings, and better morning recovery compared to melatonin-only products.

Final Verdict
Nello Supersleep is our top-scoring Amazon-available sleep drink mix. The ashwagandha and Maizinol saffron approach, low-additive formulation, and meaningful magnesium glycinate dose make it a standout product in a crowded category.
If you want our single top-scoring sleep pick, Nello Supercalm remains our overall #1. But if you prefer a formula built specifically around saffron extract and L-glycine for nighttime use, Nello Supersleep is a strong fit at its tier.

Ashwagandha is a clinically studied adaptogen shown to lower cortisol and ease the transition into sleep without any hormonal sleep aid. Maizinol, a standardized saffron (Crocus sativus) extract, has emerging research supporting mood balance and relaxation in the evening.
Magnesium glycinate supports the production of GABA — the primary inhibitory neurotransmitter responsible for calming neural activity and preparing the brain for sleep. The glycinate form is chelated to glycine, improving absorption and reducing the digestive issues sometimes associated with other magnesium forms, while the added L-glycine offers its own calming, sleep-supportive effects.
The U.S. National Center for Complementary and Integrative Health notes that non-pharmacological approaches to sleep can be effective for many adults, particularly when targeting both evening calm (via ashwagandha and saffron) and sleep depth (via magnesium-supported GABA). Our Nello Supersleep review found this dual-action approach the meaningful differentiator over melatonin-only competitors.
Does Nello Supersleep contain melatonin?
No. Nello Supersleep is completely melatonin-free. It relies on ashwagandha, Maizinol saffron extract, L-glycine, and magnesium glycinate to ease the transition into sleep — and is one of the key reasons our Nello Supersleep review ranks it as a top Amazon-available pick in the Sleep silo.
Where can I buy Nello Supersleep?
Nello Supersleep is available on Amazon, sold and fulfilled by Amazon with fast Prime shipping. This makes it easy to try without committing to a direct-from-brand subscription.
How long does it take to work?
Most users notice improvements in sleep onset within the first few nights. The full benefits — particularly improved sleep depth from magnesium glycinate and L-glycine — typically build over 1–2 weeks of consistent nightly use.
Is Nello Supersleep vegan-friendly?
The powder drink mix format avoids gelatin capsules, and the low-additive ingredient list is a plus for plant-based diets. As always, check the label for the most current allergen and dietary information, since ingredient sourcing can change between batches.
