Analysis

The tablet supplies 5 mg melatonin with small amounts of B6 and calcium. Melatonin is the only ingredient likely to drive the sleep effect.

The amount may help established users with sleep onset but is not a conservative starting point. Standard release also provides no specific overnight-maintenance advantage.

Sixty servings and one tablet make daily use simple. A lower-dose option would provide more flexibility for sensitive users.

Who is it for
  • Adults with established tolerance to 5 mg
  • Users wanting one tablet
  • People focused on sleep onset
Best for
  • Occasional sleep timing
  • Established nighttime routines
  • Users who do not need sustained release

Pros

  • Clear 5 mg dose
  • One-tablet serving
  • Sixty servings
  • Simple active profile

Cons

  • Amount may be excessive
  • B6 and calcium add little
  • No sustained release
  • Tablet cannot be precisely titrated

Warnings

  • Five milligrams may cause morning drowsiness, vivid dreams, or headache
  • Do not combine casually with alcohol or sedative medicines
  • Avoid driving after use until tolerance is clear

Nutrient quality

74 High impact

The standard delivery format offers no controlled overnight release. The elevated melatonin amount may be more than some users need.

Ingredient transparency

82 Highest impact

All listed active ingredients have individual amounts and no proprietary blend hides them. Daily directions and the complete inactive-ingredient list are not supplied.

Customer satisfaction

66 High impact

The supplied average is favorable and the aggregate pool is substantial. No specific feedback is provided to assess recurring complaints or whether experience matches the intended use.

Value for money

88 Highest impact

Serving cost is low for the disclosed formula. Supporting additions provide mixed extra value.

Melatonin · 5 mg

Melatonin directly supports sleep timing and the process of falling asleep. The amount exceeds the lower physiological range and may leave sensitive users drowsy the next morning.

The one-tablet serving clearly discloses all ingredients. Vitamin B6 and calcium are compatible but add little meaningful pathway coverage beyond melatonin.

The 5 mg dose is easy to track in one tablet but exceeds the physiological range. A standard immediate-release tablet lacks special onset or overnight-maintenance technology. Value is favorable, while independent purity verification is absent.
