Analysis

Three grams of glycine and 200 mg theanine support nighttime settling without relying solely on melatonin. Two hundred milligrams of magnesium citrate adds a meaningful mineral component.

Tryptophan and 5-HTP address serotonin-related sleep pathways, while 0.3 mg melatonin provides a restrained timing cue. The combination is broad but coherent for sleep onset and relaxation.

The powder offers thirty servings at practical value. Because two serotonin precursors are combined, medication compatibility matters more than with a simple melatonin product.

Who is it for
  • Adults seeking a multi-pathway sleep powder
  • Users who prefer low-dose melatonin
  • People not taking serotonergic medicines
Best for
  • Nighttime settling
  • Sleep timing and relaxation
  • Pill-free sleep routines

Pros

  • Three grams of glycine
  • Meaningful theanine and magnesium
  • Restrained melatonin amount
  • Clear ingredient doses

Cons

  • Combines two serotonin precursors
  • Magnesium citrate may be laxative
  • Multi-ingredient formula is harder to troubleshoot

Warnings

  • Do not combine 5-HTP and tryptophan with antidepressants or other serotonergic medicines without clinician guidance
  • Melatonin and theanine can add to alcohol, sleep medicines, or sedatives
  • Magnesium citrate may cause loose stools
  • Do not drive after taking the nighttime serving

Nutrient quality

88 Highest impact

Magnesium citrate is well understood, while the amino acids and 5-HTP lack source or purity details. Glycine and theanine have strong amounts, with magnesium, 5-HTP, tryptophan, and melatonin providing useful support.

Magnesium · 200 mgMelatonin · 0.3 mgTheanine · 200 mgGlycine · 3000 mg

Full-dose glycine with optimal theanine, low-dose melatonin, magnesium, tryptophan, and 5-HTP creates an exceptionally well-targeted sleep formula. The powder addresses body-temperature regulation, circadian signaling, relaxation, and serotonin-related pathways with substantial dosing.

Tryptophan is only modest, and the combination of two serotonin precursors adds interaction complexity. 5-HTP and tryptophan can interact with SSRIs, SNRIs, MAO inhibitors, and other serotonergic medicines, while the full blend may cause marked drowsiness.

Magnesium citrate, glycine, L-theanine, tryptophan, 5-HTP, and low-dose melatonin create strong relaxation and nighttime support. Theanine and glycine are supplied at particularly useful amounts.

The formula is well balanced for evening use and fully discloses every active amount. Tryptophan and 5-HTP can increase serotonin effects, so combining it with SSRIs, SNRIs, MAO inhibitors, or other serotonergic medicines warrants professional review.

Glycine, magnesium, tryptophan, L-theanine, 5-HTP, and low-dose melatonin create a coordinated nighttime formula. Glycine and theanine are well dosed, while tryptophan is modest and overlaps with 5-HTP on the serotonin pathway.

The powder addresses sleep-related calm more directly than daytime mood stability. Combining 5-HTP and tryptophan with SSRIs, SNRIs, MAO inhibitors, or other serotonergic medicines can raise serotonin risk and add sedation.

A full glycine amount, tryptophan, theanine, 5-HTP, and low-dose melatonin form a focused sleep-support formula. Restorative sleep is relevant to healthy aging, although the product does not directly address mitochondrial decline, oxidative stress, or structural aging.

All active amounts are clearly disclosed and generally align with the sleep purpose. Combining tryptophan and 5-HTP can increase serotonergic effects, so the product is unsuitable with serotonergic medicines unless a clinician approves it.

Glycine, magnesium citrate, theanine, tryptophan, 5-HTP, and low-dose melatonin form a substantial sleep-support formula. Better sleep may indirectly support memory consolidation and next-day mental clarity.

The product does not directly target neuronal structure, memory signaling, or daytime cognitive performance. Tryptophan and 5-HTP both raise serotonin precursors and should not be combined with SSRIs, SNRIs, MAO inhibitors, or other serotonergic medicines without specific medical guidance.

Magnesium · 200 mg

Glycine, magnesium, theanine, 5-HTP, tryptophan, and low-dose melatonin form a well-dosed sleep formula with indirect weight-management relevance. Better sleep and appetite-related serotonin pathways may support adherence, but they do not directly increase fat loss.

No thermogenic, fiber, protein, or thyroid strategy is present, so breadth is limited to sleep and appetite signaling. Combining 5-HTP and tryptophan can compound serotonergic medicines and may increase sedation.

The powder supplies a full 3,000 mg serving of standard L-glycine and is easy to mix for nighttime use. Magnesium, theanine, tryptophan, 5-HTP, and low-dose melatonin create a coordinated sleep formula with favorable glycine cost efficiency. The 5-HTP and tryptophan can raise serotonin and may interact with serotonergic medicines such as SSRIs or MAO inhibitors.

The low melatonin amount is physiologically aligned, and a liquid packet supports rapid, simple dosing. No sustained-release technology or independent purity verification is disclosed. The complex sleep blend partly supports the elevated cost, while 5-HTP may interact with serotonergic antidepressants.

87 Performance

Sleep Regimen 3-in-1

NOW
The same theanine amount is paired with clearly sourced 5-HTP and a direct melatonin component, with strong sleep alignment and a concise label. It omits magnesium, glycine, and tryptophan, while melatonin is much higher than in the original.
82 Performance

Tranquil Sleep

Natural Factors Stress-Relax
Suntheanine preserves the original theanine amount and combines it with sourced 5-HTP and melatonin in a focused sleep formula. The 5-HTP amount is lower and magnesium, glycine, and tryptophan are omitted, while melatonin is higher.
77 Performance

R.E.M. Maintenance

Metabolic Maintenance
A larger glycine amount is paired with magnesium glycinate, the same 5-HTP amount, and a modest melatonin amount, supporting strong sleep and mood alignment. Theanine and tryptophan are omitted, but magnesium form disclosure is clearer than in many multi-ingredient sleep products.
85 Budget

3 a.m. Melatonin Fast Dissolve Lavender Vanilla

Natrol
The much lower serving cost keeps theanine and melatonin in a short formula with strong sleep alignment. Theanine is lower and melatonin is substantially higher, while magnesium, glycine, tryptophan, and 5-HTP are omitted.
79 Budget

Melatonin 2 mg

Metabolic Maintenance
The lower serving cost provides melatonin with a small amount of glycine in a simple, long-supply format. Melatonin is higher, while glycine is far lower and magnesium, tryptophan, theanine, and 5-HTP are absent.
78 Budget

Double Strength 5-HTP 200 mg

NOW
The lower serving cost doubles the 5-HTP amount and adds small amounts of glycine, taurine, and inositol. It omits magnesium, tryptophan, theanine, and melatonin, so it fits a focused 5-HTP preference rather than the original broad sleep blend.
82 Value

Advanced Magnesium Complex

AOR Advanced Orthomolecular Research Advanced
The lower serving cost supplies more magnesium through ascorbate, aspartate, glycinate, and malate, plus a meaningful glycine contribution. It omits theanine, tryptophan, 5-HTP, and melatonin, so the value is strongest for mineral and glycine support rather than a full sleep stack.
80 Value

L-Theanine 100 mg

Metabolic Maintenance
Suntheanine and glycine provide a simple alternative with good ingredient clarity and cognitive alignment. The serving cost is not lower and both ingredients are below the original amounts, but the narrow formula may reduce unnecessary overlap for users who do not want melatonin or 5-HTP.
73 Value

Restful Sleep Blackberry Zen

OLLY
The lower-complexity blend retains the original theanine amount and adds melatonin with small amounts of chamomile, passionflower, and lemon balm. Its serving cost is not lower, and it omits magnesium, glycine, tryptophan, and 5-HTP, so value depends on preferring a gummy sleep blend.
