Analysis

GABA, glycine, and taurine provide a simple calming base, supported by inositol and a small amount of valerian. The combination is more useful than any single supporting ingredient at these amounts, and the label makes each dose easy to assess.

The blend fits evening relaxation and everyday stress support, but valerian is present at a very low amount and magnesium contributes little. Niacinamide avoids the flushing commonly associated with nicotinic acid, while vitamin B6 plays a supporting role.

A one-capsule serving and low cost make regular use convenient. Additive calming effects are the main trade-off, particularly when used with alcohol, sleep aids, or other sedating products.

Who is it for
  • Adults seeking gentle evening relaxation
  • People wanting an inexpensive multi-ingredient calming formula
Best for
  • Stress support
  • Pre-sleep relaxation
  • Simple one-capsule use

Pros

  • Coherent mix of calming ingredients
  • All active amounts are disclosed
  • One capsule per serving
  • Low cost per serving

Cons

  • Valerian amount is very low
  • Glycine and taurine are modestly dosed
  • Magnesium contribution is minimal

Warnings

  • GABA, valerian, glycine, and taurine may cause additive drowsiness.
  • Avoid use before driving and use caution with alcohol, sleep medicines, or other sedatives.

Nutrient quality

71 High impact

The ingredients fit calming and stress support, with magnesium bisglycinate providing a favorable form. Low amounts of magnesium, glycine, taurine, and valerian keep the formula from delivering strong dose depth.

.

Ingredient transparency

78 High impact

Active amounts are broadly clear and no proprietary blend hides the listed doses. Missing inactive ingredients and incomplete usage or source details prevent full label transparency.

.

Customer satisfaction

70 High impact

The average rating is strong and backed by a very large review base. No specific experience details are supplied, so repetitive complaints and real-world calming effects remain uncertain.

.

Value for money

90 Highest impact

The serving cost is very low and the concise formula avoids unrelated extras. Dose depth is modest, but the accessible price still supports good practical value.

B Goal FitB- Strength of SupportB- CoverageA- Formula Quality
Magnesium · 6.5 mgGlycine · 200 mgGABA · 200 mgVitamin B6 · 8 mg

GABA, glycine, taurine, and inositol form a direct calming neurotransmitter-focused blend. Valerian adds a small sedative-herb component.

Most amounts are modest, and the 6.5 mg magnesium contribution is too low to matter for stress support. The concise formula is coherent, though evidence for oral GABA and these exact low-dose combinations remains limited.

Magnesium · 6.5 mgGlycine · 200 mg

A multi-ingredient calming blend has clear sleep relevance but relies on uneven dosing. GABA is supplied at a useful blend amount, while glycine, taurine, inositol, magnesium, and valerian add several relaxation mechanisms.

Glycine and valerian are far below typical sleep servings, and most sources lack purity or standardization details. Additive calming effects may cause drowsiness, so the formula should not be used before driving or combined casually with alcohol or sedative medicines.

Vitamin B6 · 8 mgMagnesium · 6.5 mg

GABA, glycine, taurine, and valerian create a coherent calming blend that may indirectly support mood through relaxation and sleep. The emphasis is on short-term calming rather than broader mood regulation.

Most active amounts are small, and oral GABA has uncertain access to the brain. Valerian and the other calming ingredients may add to drowsiness, so the formula is a poor fit before driving.

B Active Ingredient Quality & BioavailabilityA- Dose, Safety & Label TransparencyC Value

The calming blend includes clearly identified niacinamide at a practical supporting amount. A standard capsule provides no special release feature, but the form has low flush potential. The low serving cost is favorable, although niacin is a supporting ingredient rather than the main focus.

B- Active Ingredient Quality & BioavailabilityB+ Dose, Safety & Label TransparencyB- Value

The 200 mg GABA dose is transparent and useful in a calming blend, although the ingredient is not a branded fermented form. A vegetable capsule offers conventional delivery, and the low serving cost supports good practical value. Valerian, glycine, taurine, and GABA may have additive calming effects, so the blend may cause drowsiness in sensitive users.

Glycine · 200 mg OverallScore69
B- Active Ingredient Quality & BioavailabilityC+ Dose, Safety & Label TransparencyB- Value

Standard glycine in a vegetable capsule provides straightforward delivery but lacks a named purity standard. The 200 mg amount is low alone, while GABA, taurine, inositol, magnesium, and valerian create a broader calming formula. Valerian and the other calming ingredients may increase drowsiness, so the formula is poorly suited to use before driving.
