Vinatura Magnesium Complex Sleep Aid vs THORNE Magnesium Glycinate
When comparing sleep-support magnesium supplements, formulation drives both experience and tolerability.
Vinatura combines elemental magnesium (glycinate + malate) with L-theanine and melatonin, an all-in-one pre-bed stack.
THORNE focuses on one active magnesium as glycinate/bisglycinate - a minimalist, well-tolerated chelate that allows flexible dosing.
Ingredients
THORNE, each capsule provides 120 mg magnesium as glycinate/bisglycinate—a chelated form linked to favorable absorption; in limited-absorption settings, diglycinate reaches earlier peaks and outperforms magnesium oxide [16].
Excipients: hypromellose (capsule), silicon dioxide, MCT oil (some sensitive users report bloating).*
Vinatura, each 2-capsule serving delivers 100.5 mg elemental magnesium (glycinate + di-magnesium malate—two highly bioavailable forms), plus L-theanine 50 mg (calm without sedation) and melatonin 5 mg (supports the sleep–wake rhythm).
Evidence snapshots: Magnesium’s sleep effects are mixed overall, with clearer signals in older adults or those with low magnesium status [1,2,3].
L-theanine offers modest improvements in sleep onset and subjective quality [1]; melatonin often enhances sleep quality/efficiency when sleep schedules are misaligned [4,5,6].
Combination data suggest possible added benefits from magnesium + melatonin [3,7,8] and magnesium + L-theanine [9,10,11]. Excipients: hypromellose (capsule), silicon dioxide, magnesium stearate.
Both products use hypromellose capsules; THORNE Magnesium Glycinate is made without gluten, dairy, and soy, while Vinatura Magnesium Complex Sleep Aid is made without soy, tree nuts, wheat, and dairy.
Effectiveness
For this THORNE Magnesium Glycinate supplement review, user feedback often praises the product’s quality and simplicity.*
A Reddit user confirmed, “THORNE is definitely top-quality stuff.”*
Christine also noted on Amazon, “These are quality ingredients… the company is completely transparent about what’s in their products…”*
However, not all reviews are positive. A few users mentioned sensitivity to fillers or capsule size.*
Greg, a customer on THORNE’s official site, wrote: “I like taking Magnesium Glycinate before bed, but the added MCT oil gives me bloating and stomach cramps. Since no one else mentioned this, maybe it’s just me…”*
As for Vinatura Magnesium Complex Sleep Aid, users often appreciate its gentle effect on the stomach and its practical use before bedtime.*
CLAUDIO shared that the product “Helps me fall asleep and stay asleep all night.”*
On the other hand, some reviews mention needing two capsules per dose or not noticing much difference.*
These mixed reviews show that results vary from person to person, depending on individual needs and body responses, which explains why both products receive diverse opinions.*

Multiple Benefits, One Choice: Which Supplement Aids Sleep Most Effectively?
Both products aim for a calmer pre-sleep state but take different paths.
THORNE Magnesium Glycinate centers on one active: 120 mg magnesium as glycinate/bisglycinate, a chelated form often linked to favorable absorption and gentler GI tolerance versus some inorganic salts [12,13,14,15,17] and with advantages reported in limited-absorption settings [16].
Vinatura Magnesium Complex Sleep Aid uses a pre-bed blend per serving: 100.5 mg elemental magnesium (glycinate + malate) plus L-theanine 50 mg and melatonin 5 mg.
Current evidence suggests melatonin often supports sleep quality and efficiency, especially when the circadian rhythm is disrupted [4,5,6].
L-theanine shows modest benefits for sleep onset and subjective quality [1]. Magnesium’s impact on sleep is mixed overall, with clearer signals in older adults or those with low magnesium status [1,2,3].
Importantly, combination data indicate potential added benefits when magnesium is paired with melatonin [3,7,8] or with L-theanine [9,10,11].
How to choose?
If the priority is easing sleep onset and supporting consistency, a blend that includes melatonin aligns more directly with the literature - favoring Vinatura Magnesium Complex Sleep Aid [1,11].
If the goal is magnesium-focused support, flexible dosing, or avoiding melatonin, THORNE offers a streamlined, adjustable option grounded in a well-studied chelated form [12,17]. Individual response varies, so preferences, routines, and tolerance should guide selection.
Conclusion
Both options can support a calmer pre-sleep routine, but fit different needs. Vinatura Magnesium Complex Sleep Aid offers an all-in-one blend aligned with sleep-onset support.
THORNE Magnesium Glycinate provides a magnesium-only path with flexible dosing and lower cost per serving. Effectiveness varies by tolerance, ingredient preference, and budget.
Above all, consistent sleep hygiene, balanced nutrition, and regular physical activity remain the foundation; with those in place, supplements can help support relaxation and nightly rest.
