Product analysis
NutraSleep may offer modest help with sleep and relaxation through magnesium, GABA and calming herbs. Benefits depend on the preparation, and several herbal preparations are unidentified.
AI assessment of the formula, label and price. How scoring works
Nutrient Quality28
The calcium and magnesium use mixtures of forms whose proportions are undisclosed. Magnesium includes oxide alongside citrate, leaving the balance between the better and less readily absorbed forms uncertain.
Ingredient Transparency59
Amounts are listed, but most ingredient forms are not identified. The missing calcium and magnesium proportions make their mixtures harder to compare.
Value For Money36
Value is mixed, with the magnesium blend and taurine offering weaker value. Calcium looks more moderate, while value for several other ingredients remains uncertain.
Customer Satisfaction70
Customers tend to give favorable ratings, with several hundred ratings supporting that picture. No specific experiences are described, so the reviews do not establish sleep benefits.
Product Focus54
Sleep and relaxation are the clearest practical uses, though expected benefits are modest and preparation-dependent. The sedating role of valerian makes the broader energy claims less convincing.

Magnesium · 440 mgGABA · 600 mgVitamin B6 · 2 mg
GABA provides the clearest short-term task-stress connection, while magnesium offers conditional support when intake or status is low. Passionflower’s supplied evidence is chiefly acute or procedural anxiety, and its unidentified preparation limits transfer of specific findings. Valerian adds an uncertain sleep- or anxiety-related contribution; broad everyday relief is inconsistent. Taurine’s physical and oxidative-stress evidence does not establish emotional stress relief.

Magnesium · 440 mg
Magnesium offers limited evidence for modest sleep improvement, while GABA has small, preparation-specific studies suggesting possible sleep support. Chamomile has mixed findings for reported sleep quality. Valerian and passionflower depend on the preparation used, which is not established here. These findings use the selected four-tablet serving; taurine's assigned contribution does not establish a sleep-specific human benefit.
How this product is rated for Sleep Support
Ingredient fit66
The formula has several sleep-related ingredients alongside other actives, with partial amount support.
Goal fit
Magnesium and calming ingredients provide the sleep connection within a broader formula.

Vitamin B6 · 2 mgMagnesium · 440 mg
Magnesium and niacin can help address nutrient shortfalls associated with depressed mood or apathy. Their benefit depends on low intake or deficiency. GABA's preparation-specific stress findings and valerian's sleep and relaxation role do not establish direct routine mood improvement. The selected four-tablet serving supplies 440 mg magnesium, above the saved upper comparison amount without showing greater benefit or suitability at that exposure.
How this product is rated for Mood Support
Ingredient fit74
magnesium contribute to the saved ingredient and amount findings. The practical mood relevance depends on the specific roles and limitations described above.
Goal fit
The formula includes mood-related ingredients alongside active ingredients serving other purposes, so its focus is broader than mood support.
Dose adequacy
The included ingredients provide mixed or partial comparison amounts, limiting the amount-based contribution of this serving.
Pathways60
The included ingredients emphasize the routes identified below. Ingredient coverage does not itself demonstrate a direct or broader mood improvement.
Depth
The strongest included route is neural calming; this describes ingredient roles rather than a demonstrated emotional outcome.
Breadth
One main route receives substantial support from the included ingredients; broader emotional benefits are not established.
Evidence84
The strongest included ingredient determines the evidence comparison. Its supplied preparation, population and emotional-outcome limitations remain relevant.
Evidence strength
Magnesium leads the included evidence comparison, while its population and outcome limitations still apply.
Studied preparation
The saved findings accept the included preparations for comparison; this does not establish interchangeable extracts or a guaranteed mood effect.
Formulation logic100
The supplied findings identify no missing partner or configured ingredient conflict. Meeting an amount threshold does not establish clinical effectiveness.
Partner coverage
The included ingredients do not require a missing partner under the supplied findings; this does not establish added benefit from combining them.
Conflicts
No configured ingredient conflict was identified in the supplied formula; this is a limited interaction check.
Effective doses
All ingredients included in this finding meet its minimum amount threshold, which is not a proven effective mood dose.
