Melatonin 3 mg
21st Century
Score 75
This product primarily targets sleep support with a standard 3mg melatonin dose, often effective for sleep regulation. The included calcium carbonate, while a source of calcium, is less bioavailable and lacks crucial co-factors like Vitamin D for effective bone and nail health, limiting its utility for those goals.

Analysis
This 21st Century Melatonin supplement provides a moderate dose of 3mg melatonin, which is generally effective for initiating sleep for many users without causing excessive morning grogginess. Melatonin is a well-researched hormone that helps regulate the sleep-wake cycle, making this product a suitable option for individuals seeking aid with occasional sleeplessness or adjusting to new sleep patterns.
The product also includes 94mg of calcium in the form of calcium carbonate. While calcium is crucial for bone and nail health, calcium carbonate requires stomach acid for optimal absorption and is less bioavailable compared to other forms like calcium citrate. More importantly, it lacks vital co-nutrients such as Vitamin D and K, which are essential for calcium absorption into the bones and proper utilization, thus making its contribution to robust bone and nail health goals quite limited as a standalone component.
Pros
- Contains a well-researched and generally effective 3mg dose of melatonin for sleep.
- Melatonin is known for helping regulate the sleep-wake cycle.
Cons
- Calcium carbonate is a less bioavailable form of calcium and requires stomach acid for absorption.
- Lacks essential co-factors like Vitamin D and K for optimal calcium absorption and bone health benefits.
- The small amount of calcium provided has minimal impact on overall bone or nail health.
Warnings
- Melatonin may cause drowsiness, dizziness, or headache in some individuals.
- Consult a healthcare professional before use, especially if pregnant, nursing, taking medication, or having a medical condition.

Goals
Impact
Highest effect
The 3mg dose of melatonin is widely regarded as an effective and appropriate amount for many individuals seeking to improve sleep onset and quality. Melatonin is a well-established and researched ingredient for regulating the sleep-wake cycle.
Impact
Moderate effect
Melatonin's primary benefit for stress relief comes indirectly through its ability to improve sleep quality. Better sleep can significantly reduce perceived stress levels, though it's not a direct anxiolytic or stress-reducing compound in itself.
Impact
Lower effect
While melatonin contributes to general well-being through improved sleep, the product's limited nutritional profile (basic calcium without cofactors) means it does not offer broad spectrum support for overall general health beyond sleep regulation.
Impact
Lower effect
Adequate sleep, facilitated by melatonin, is crucial for cognitive function, memory consolidation, and overall brain health. While melatonin supports sleep, it does not contain specific nutrients directly known for enhancing brain function or neuroprotection beyond this indirect benefit.
Impact
Situational effect
The calcium included is in the form of calcium carbonate, which has lower bioavailability and requires adequate stomach acid for absorption. Crucially, it lacks essential co-factors like Vitamin D and K that are necessary for calcium to be properly absorbed and integrated into bone tissue for effective support.
Impact
Situational effect
Similar to bone health, the calcium provided is in a less optimal form (calcium carbonate) and is not accompanied by synergistic nutrients like Vitamin D, which limits its overall effectiveness for supporting nail strength and health.
Impact
Situational effect
Melatonin has antioxidant properties and its role in sleep can contribute to cellular repair, which is tangentially related to anti-aging. However, this product is not formulated with ingredients primarily targeted at comprehensive anti-aging benefits.
Impact
Situational effect
Melatonin has some indirect links to immune function through its role in sleep, which is vital for immune health. However, this product does not contain any ingredients directly recognized for their primary role in boosting or regulating the immune system.
Impact
Limited evidence
There is no scientific evidence to suggest that either melatonin or the small amount of calcium carbonate in this product directly supports or enhances testosterone levels.
