- Large 100-count bottle provides excellent value for regular use
- Non-habit forming, drug-free formula enhances safety and peace of mind
- Includes Vitamin B6 to further support sleep cycle regulation
- High customer rating indicates strong user satisfaction

Natrol Melatonin 10 mg Time Release is a dietary supplement designed for adults who struggle with falling asleep or staying asleep through the night. The dual-layer tablet delivers an initial quick-release dose to help you drift off quickly, followed by a controlled-release inner layer that provides sustained melatonin levels to support uninterrupted sleep. This product is ideal for those with occasional insomnia, jet lag, or shift work sleep disruption who prefer a non-habit forming, drug-free solution.
The standout feature of this supplement is its innovative time release formulation. The outer layer dissolves rapidly to deliver 10 mg of melatonin for fast sleep onset, while the inner layer releases the remaining melatonin gradually over several hours. This design aims to mimic the body's natural melatonin production pattern, helping users not only fall asleep but also maintain deep sleep throughout the night. Many users report waking up feeling refreshed without grogginess, which is a common concern with higher-dose immediate release melatonin.
Build quality is solid: the tablets are compact, easy to swallow, and come in a sturdy bottle with a child-resistant cap. The 100-count supply offers a generous 100-day supply if taken as directed, making it a cost-effective choice for regular users. Natrol is a well-known brand in the supplement industry, and this product lives up to its reputation for purity and potency, being free from artificial colors, gluten, and major allergens.
A potential drawback is the fixed 10 mg dosage, which may be too high for melatonin-sensitive individuals. Those new to melatonin should consider starting with a lower dose (e.g., 5 mg) before moving to 10 mg. Additionally, the time release mechanism may vary in effectiveness based on individual digestive rates; some users might experience uneven release. However, for most adults, this product offers a reliable and convenient sleep aid solution.
Overall, the Natrol Melatonin 10 mg Time Release earns a strong recommendation for its effective dual-layer technology, long-lasting supply, and safety profile. It is a practical choice for anyone seeking a dependable, non-prescription sleep support supplement. While the dosage may not suit everyone, its high user ratings and thoughtful design make it a top contender in the melatonin market.

Buying Guide
Dosage Forms
Melatonin is available in many formats, and your preference matters. Natrol excels here with fast dissolve tablets in strawberry flavor, time release tablets, and a liquid version. The fast dissolve options dissolve in your mouth without water, making them convenient for travel or late‑night use. The time release tablet from Natrol uses a dual‑layer design: the outer layer dissolves quickly to help you fall asleep fast, while the inner layer releases melatonin gradually through the night. In contrast, NOW offers only veg capsules, which you swallow with water. If you dislike swallowing pills, Natrol’s alternatives are a clear advantage.
Liquid melatonin provides flexibility in dosing. Natrol’s liquid comes in a berry flavor and can be easily adjusted drop by drop. For those who prefer a traditional pill, NOW’s capsules are simple and reliable. Consider which format aligns with your daily routine when choosing.
Potency Options
Both brands offer a range of dosages, but Natrol covers a broader spectrum. Natrol has 5 mg and 10 mg fast dissolve tablets, a 10 mg time release, and a 2.5 mg liquid. NOW, in this comparison, is only available in 3 mg capsules. The right dose depends on your sensitivity and sleep issues. Many adults start with 3 mg, but some need higher amounts for occasional sleeplessness or jet lag. Natrol’s 10 mg options suit those who require a stronger supplement, while NOW’s 3 mg works well for a gentle start. Always consult a healthcare professional to find your optimal dose.
Ingredient Quality and Purity
Both Natrol and NOW are reputable brands known for quality. Natrol states its melatonin supplements are 100% drug‑free and non‑habit forming, and the fast dissolve tablets are vegetarian. NOW goes a step further with GMP (Good Manufacturing Practices) certification, meaning every aspect of production is verified for stability and potency. NOW’s melatonin is also sourced from a trusted facility that carries NPA A‑rated certification. If third‑party validation matters to you, NOW’s transparency may be appealing. However, Natrol also maintains high standards and offers a satisfaction guarantee.
Special Features
Natrol’s product line includes features that enhance the user experience. The fast dissolve tablets come in a delicious strawberry flavor, and the liquid version is berry‑flavored. The time release formula is ideal for those who wake up in the middle of the night. NOW, on the other hand, keeps things simple: no flavors, no timed release, just pure melatonin in a capsule. For some, this simplicity is a benefit, especially if they are sensitive to flavors or prefer minimal ingredients. Also, Natrol’s liquid provides an alternative for people who have difficulty swallowing pills or want precise dosing.
