Best Melatonin Supplements of 2025 - Top 5 Compared

Thorne Melaton-5 delivers a potent 5mg dose of melatonin in each capsule, making it one of the most effective sleep aids available. The supplement is NSF Certified for Sport, meaning it undergoes four rounds of testing to ensure purity and accurate labeling - a crucial factor given the inconsistency found in many melatonin products. The tiny capsule is easy to swallow, though users should take care to swallow it quickly to avoid any unpleasant taste. While the 5mg dose is higher than many standard melatonin supplements, it's particularly effective for those who need stronger sleep support.

The formulation contains minimal additional ingredients and is free from gluten, dairy, and soy. Some users may find the higher dose causes next-day grogginess initially, but this typically subsides with continued use. The price point is higher than basic melatonin supplements but justified by the superior quality control and effectiveness. For those seeking a reliable, high-quality melatonin supplement that delivers consistent results, Thorne Melaton-5 is the clear top choice.

Nature Made Melatonin 3mg provides an excellent balance of quality and affordability, with each bottle containing 240 servings at a price that works out to just pennies per dose. The supplement is USP-verified, meaning it has been tested for purity and accurate labeling - an important consideration given the inconsistencies found in many melatonin products. The 3mg dose is a standard starting point that works well for most adults, helping to regulate sleep cycles without being overly potent. While the formulation is basic without additional sleep-support ingredients, this simplicity makes it a good choice for those who want straightforward melatonin supplementation.

The tablets are small and easy to swallow, though they can leave an unpleasant taste if chewed or allowed to dissolve in the mouth. Some users may find they need to gradually increase to two tablets for optimal effect. For those looking for an economical melatonin supplement from a reputable brand that can be used nightly without breaking the bank, Nature Made Melatonin 3mg is an outstanding choice.

Olly Sleep Gummy offers a delicious alternative to traditional melatonin pills, with a blackberry flavor that makes supplementation enjoyable. Each serving of two gummies provides 3mg of melatonin along with 100mg of L-Theanine and a blend of chamomile, passionflower, and lemon balm extracts - ingredients known to promote relaxation. The gummy format makes it ideal for those who dislike swallowing pills, with no need for water or food when taking them. However, the gummies do contain added sugars and glucose syrup, which may be a concern for some users.

The botanical blend enhances melatonin's effects, helping users not just fall asleep but also achieve more restful sleep. Some users report more vivid dreams when taking this formulation, likely due to the combination of ingredients. While more expensive than basic melatonin tablets, the enjoyable delivery system and comprehensive formulation justify the premium for many users. Those looking for a melatonin supplement that's pleasant to take while still being effective will find Olly Sleep Gummy an excellent choice.

NOW Liquid Melatonin offers a versatile alternative to traditional melatonin supplements with its liquid formulation that allows for precise dosing adjustments. The liquid format is absorbed more quickly than tablets or capsules, potentially leading to faster sleep onset. Each bottle comes with a dropper that makes it easy to measure out the desired dose, whether sticking with the standard 3mg serving or adjusting up or down based on individual needs. The citrus-flavored liquid can be taken directly or mixed into a beverage, providing flexibility in administration.

However, users should be aware the formula contains xylitol, which is toxic to pets, requiring careful storage. Some users find the flavor slightly medicinal, though most tolerate it well, especially when mixed with tea or another beverage. The liquid form makes this an excellent choice for those who have difficulty swallowing pills or prefer more control over their melatonin dosage. While slightly more expensive than basic tablet formulations, the added convenience and dosing flexibility make NOW Liquid Melatonin a standout option in its category.

Pure Encapsulations Melatonin 0.5mg fills an important niche in the sleep supplement market by offering an ultra-low dose option that's ideal for sensitive individuals or those new to melatonin supplementation. The 0.5mg dose is particularly effective for circadian rhythm regulation when taken several hours before bedtime, as recommended by sleep specialists. The small capsules are easy to swallow and allow users to precisely control their dosage by taking one or more as needed. While the per-serving cost is higher than standard 3mg or 5mg melatonin supplements, the ability to start with such a low dose and gradually adjust makes this product valuable for those concerned about potential side effects like morning grogginess.

The formulation comes from a reputable brand known for high-quality supplements, providing assurance of purity and accurate dosing. Some users may eventually need to take multiple capsules to achieve desired effects, but having the option to start low and adjust makes this an excellent choice for cautious supplementation. For those seeking gentle, precisely dosed melatonin support, Pure Encapsulations 0.5mg is an outstanding option.
