Analysis

Melatonin provides the strongest direct sleep signal and may support sleep onset. Sensoril ashwagandha adds stress-resilience support, while magnesium citrate contributes a modest mineral amount rather than a full magnesium serving.

The branded ashwagandha extract and explicit active amounts make the formula easy to assess. Two gummies are convenient for many users, but the immediate-release melatonin amount may be more than some people need.

The low serving cost compares well for a combined sleep-and-stress product. People prone to next-day grogginess may prefer to begin with a lower melatonin product rather than trying to split an uneven gummy serving.

Who is it for
  • Adults whose sleep difficulty is linked with evening stress
  • Established melatonin users who tolerate a larger amount
Best for
  • Sleep onset support
  • Nighttime stress reduction
  • Gummy-based evening routines

Pros

  • Uses branded Sensoril ashwagandha
  • Combines stress and sleep pathways
  • Includes magnesium citrate
  • Clearly disclosed amounts
  • Good serving value

Cons

  • Melatonin amount may be more than necessary
  • Immediate-release format
  • Adds 5 g carbohydrate
  • Magnesium amount is modest

Warnings

  • The 5 mg melatonin amount may cause next-day grogginess, headache, or vivid dreams, especially in new users.
  • Ashwagandha and melatonin may add to alcohol, sleep medicines, or other sedatives and further impair alertness.
  • Ashwagandha may affect thyroid activity and has rare liver-injury reports, making thyroid or liver conditions especially relevant.
  • Avoid during pregnancy or breastfeeding because the combination is not appropriate for that setting.
  • Do not drive or perform safety-sensitive work after taking it.

Nutrient quality

Magnesium citrate and branded Sensoril ashwagandha provide well-identified forms. Ashwagandha is well aligned, while melatonin is stronger than many users need for sleep onset, and melatonin, magnesium, and ashwagandha form a concise sleep and relaxation formula.

Ashwagandha KSM-66 600 mg

NutraBio
<p>A full-strength KSM-66 root extract provides clearer, more concentrated ashwagandha support for stress and mood. It lacks melatonin and magnesium, while the substantial ashwagandha amount may be more than sensitive users need.</p>
86 Performance

Ashwagandha Sensoril

Natural Factors Stress-Relax
<p>Sensoril provides a focused branded ashwagandha option with strong form assurance and no gummy carbohydrates. It removes the original's relatively strong melatonin amount, but also gives up direct sleep-timing support and magnesium.</p>
88 Performance

Melatonin 1.0 mg Orange Flavor

Source Naturals Sleep Science
<p>A low melatonin amount is better aligned with cautious sleep-onset use and may reduce next-day drowsiness. The single-ingredient formula is easier to tailor, though it omits Sensoril and magnesium.</p>
87 Budget

Standardized Extract Ashwagandha 450 mg

NOW
<p>A standardized ashwagandha extract provides a substantially higher focused amount at a much lower serving cost. It may support stress resilience, but it omits magnesium and melatonin, so direct sleep-timing support is lost.</p>
86 Budget

Optimized Ashwagandha

Life Extension
<p>Sensoril preserves the branded ashwagandha form at a much lower serving cost and a lighter focused amount. The capsule avoids gummy carbohydrates but does not include magnesium or melatonin for direct sleep support.</p>
87 Budget

Melatonin 1 mg

Nature's Bounty
<p>A low melatonin amount offers simple sleep-onset support at a much lower serving cost and may reduce morning grogginess compared with the original amount. Ashwagandha and magnesium are absent, so stress-related sleep support is narrower.</p>
86 Value

Ashwagandha

Jarrow Formulas
<p>A focused ashwagandha extract provides a practical amount and a long supply at a much lower serving cost. The formula may support stress-related sleep issues but lacks magnesium and melatonin for direct sleep timing.</p>
86 Value

Ashwagandha Extract 450 mg

Swanson
<p>A clearly identified ashwagandha root extract with withanolides offers a higher focused amount at a much lower serving cost. It avoids gummy carbohydrates, while the absence of melatonin and magnesium narrows sleep-specific coverage.</p>
86 Value

Melatonin 3 mg Fast Dissolve Strawberry Natural Flavor

Natrol
<p>A moderate fast-dissolve melatonin amount supports sleep initiation at a much lower serving cost and is less aggressive than the original amount. It does not provide ashwagandha or magnesium, so the value comes from focused rather than broad support.</p>
