Analysis

GABA, magnesium, taurine, inositol, valerian, passionflower, skullcap, and chamomile approach sleep from several calming and physical-relaxation pathways. The main amounts are individually listed rather than hidden in one proprietary blend.

GABA and magnesium are supplied at substantial weights, while valerian and the other botanicals have less certain potency because plant part, extract ratio, and active markers are not given. Magnesium citrate improves the mineral blend, but the inclusion of oxide lowers absorption confidence and may increase digestive effects.

The formula fits adults seeking a strong nighttime blend and who tolerate several calming ingredients together. It is not well suited to daytime stress, fitness, heart, or detoxification use because sedation dominates the practical effect.

Who is it for
  • Adults seeking multi-ingredient nighttime relaxation
  • People who tolerate valerian and calming herbs
  • Users wanting GABA, magnesium, and taurine together
Best for
  • Sleep support
  • Nighttime stress relief
  • Physical relaxation before bed

Pros

  • Meaningful GABA amount
  • Broad calming pathway coverage
  • Taurine and inositol are individually disclosed
  • Magnesium includes citrate

Cons

  • Magnesium also includes poorly absorbed oxide
  • Botanical potency is not standardized
  • Large serving burden
  • Formula is poorly aligned with daytime goals

Warnings

  • GABA, valerian, passionflower, skullcap, and chamomile may cause additive drowsiness
  • Do not combine casually with alcohol, sleep medicines, or other sedatives
  • Do not drive, train, or perform alertness-sensitive work after taking a serving
  • The large magnesium amount may cause loose stools or stomach discomfort

Nutrient quality

70 High impact

The calming ingredients provide broad and meaningful sleep-support coverage. Mixed mineral forms, substantial magnesium, and combined sedatives create absorption and tolerability trade-offs.

.

Ingredient transparency

77 High impact

Most active amounts are disclosed and no proprietary blend hides the formula. Repeated mineral-form entries, missing herb standardization, absent inactive ingredients, and incomplete directions leave important uncertainty.

.

Customer satisfaction

66 High impact

The supplied average rating is favorable and supported by a substantial review pool. No review text is provided to assess repeated complaints or firsthand sleep experiences.

.

Value for money

84 Highest impact

Several meaningful calming ingredients support strong formula value. Mixed mineral forms and modest botanical detail keep the product from leading its category.

Magnesium · 440 mgGABA · 600 mgVitamin B6 · 2 mg

Magnesium, GABA, taurine, inositol, and several calming herbs cover nervous-system relaxation and sleep-related recovery from multiple angles. The breadth is useful, although oral GABA and some traditional herbs have less consistent human evidence than magnesium or standardized adaptogens.

Most amounts are substantial and individually listed, but the magnesium includes oxide and the botanical extracts lack active-marker standardization. The combined valerian, passionflower, skullcap, chamomile, and GABA may cause pronounced drowsiness and should not be mixed with alcohol, sleep medicines, or driving.

The blend addresses physical relaxation and nervous system calming through magnesium, taurine, GABA, and several herbs. Its broad sleep focus is useful, though the evidence and potency vary across the ingredients.

Magnesium, taurine, and GABA are supplied in meaningful amounts, while the valerian and other herbs have less certain potency. The combined calming load may cause marked drowsiness, so it should not be taken before driving or tasks that require alertness.

Magnesium, inositol, GABA, taurine, and calming herbs provide broad relaxation support, but the formula is primarily designed for sleep rather than ongoing mood regulation. Several actives have meaningful amounts, while human evidence for oral GABA and the full combination is mixed.

The active amounts are mostly clear, although magnesium includes poorly absorbed oxide and botanical standardization is absent. GABA, valerian, skullcap, passionflower, and chamomile may combine to cause marked drowsiness and impaired alertness.

The formula combines magnesium, taurine, inositol, GABA, and several calming botanicals for sleep and relaxation. Better sleep can support daily resilience, but this is a targeted nighttime product rather than broad foundational nutrition.

Mixed magnesium forms and variable evidence across the botanical and GABA ingredients limit confidence in consistent effects. Valerian, passionflower, skullcap, chamomile, and GABA may cause additive drowsiness with alcohol, sedatives, or other sleep medicines.

Magnesium · 440 mgTaurine · 875 mg

Magnesium and several calming compounds create a coherent formula for sleep support, but that niche aim only partly matches broad daily wellness. Many principal actives are disclosed at meaningful amounts rather than hidden in a blend.

Magnesium oxide lowers absorption confidence, and the numerous botanicals make the formula harder to assess for long-term general use. Valerian, passionflower, chamomile, skullcap, and GABA may add to drowsiness, so the serving is unsuitable before driving or other alertness-sensitive tasks.

Taurine and magnesium provide some cellular, metabolic, and sleep-related support relevant to healthy aging. The broader calming blend may help sleep, but direct evidence for slowing human aging is limited.

The taurine amount is useful and the magnesium amount is substantial, though magnesium oxide weakens absorption quality. Valerian, passionflower, chamomile, skullcap, and GABA may combine to cause marked drowsiness, so the formula is unsuitable before driving or other alertness-sensitive tasks.

Report overview
GABA · 600 mg OverallScore74
C+ Active Ingredient Quality & BioavailabilityA+ Dose, Safety & Label TransparencyD- Value

The clearly disclosed 600 mg GABA dose fits the effective range, but the source is not identified as a branded fermented form. A hard-pressed tablet may disintegrate more slowly than capsules, powders, or sublingual formats. GABA is combined with valerian, passionflower, skullcap, and chamomile, which may compound drowsiness and make driving after a serving unsafe.

B Active Ingredient Quality & BioavailabilityC+ Dose, Safety & Label TransparencyD+ Value

The calcium blend combines citrate with less absorbable carbonate and clearly states the mineral amount. Its moderate dose is efficiently sized, though calcium is secondary to the sleep formula. Serving value is average, and complete additive information is missing.

Magnesium citrate improves the blend, but the included oxide and undisclosed form proportions limit absorption confidence. The 440 mg elemental amount is clearly stated and vitamin B6 supports the formulation logic. Two tablets are manageable, though the serving cost is above the collection median without a patented mineral form.

Theanine Serene

Source Naturals
<p>Meaningful magnesium, GABA, taurine, L-theanine, and holy basil create a focused relaxation blend with strong sleep and stress alignment. Generic source details remain a limitation, but the formula is more concise than the original and avoids its heavy combined sedative-botanical load.</p>

Calcium & Magnesium Citrate Powder with Vitamin D3

NOW
<p>Citrate magnesium and calcium with vitamin D3 provide better-defined mineral forms than the original’s mixed citrate-and-oxide entries. It may support general relaxation when magnesium intake is low, but it does not replace valerian, GABA, or other direct sleep actives.</p>

Theanine Serene

Source Naturals Serene Science

Cal/Mag 500 mg/250 mg

NaturesPlus
<p>Chelated calcium and magnesium provide a balanced, economical mineral base at a much lower serving cost. It lacks GABA, valerian, and other direct sleep ingredients, so it is a mineral alternative rather than a complete sleep-formula substitute.</p>

Theanine Serene with Relora

Source Naturals Serene Science
<p>Magnesium, GABA, taurine, L-theanine, Relora, and holy basil provide a coherent calming base at a lower serving cost. Relora composition and generic sourcing are incomplete, but the focused blend offers better practical value with fewer overlapping sedatives.</p>

Calcium Mag & D Complex

Nature's Way
<p>Useful calcium and magnesium amounts combine citrate, malate, and aspartate forms at a lower serving cost. Carbonate and oxide remain in the mix and vitamin D3 is modest, while the absence of GABA and valerian limits direct sleep relevance.</p>
