AGZ Nightly Sleep Support Review: What Is Actually in It

A melatonin-free nighttime drink with real doses of the ingredients that have evidence behind them. The full panel, the price problem, and what it does not do.

Most sleep supplements fail on dosing rather than on ingredients. The label lists eleven promising botanicals, the panel hides them inside a proprietary blend, and the actual amount of each is a fraction of what the studies used.

AGZ does not do that, which makes it unusually assessable. Here is the panel, and here is the honest verdict.

What it is

A nighttime drink powder from AG1, sold in 13g travel packs, 30 servings per container. Two flavours — Chocolate, described as cocoa with coconut milk, and Chocolate Mint. Mixed with 4oz of water or milk, taken nightly before bed, and drinkable cold, warm or at room temperature.

It is melatonin-free, which is a deliberate positioning choice and, for this site's audience, an important one. More on that below.

The panel, per serving

Ingredient Amount
Magnesium (as 2,000mg Magtein® magnesium L-threonate + magnesium bisglycinate) 250mg
L-Theanine 200mg
Glycine 2g
Myo-inositol 1g
Ashwagandha leaf extract (5% withanolides) 300mg
Saffron stigma extract (3% crocins) 28mg
Vitamin B6 (as P5P) 5mg
Zinc (as citrate) 12mg
Calming herbs and antioxidant blend 2.4g

That blend contains chamomile, phosphatidylserine, valerian, tart cherry, lemon balm, green kiwi, Baikal skullcap, passionflower, lavender and holy basil. 35 calories, under 1g of sugar, sweetened with stevia.

The doses are real. 200mg of L-theanine is the amount used in the research rather than a sprinkle. 300mg of ashwagandha extract standardised to 5% withanolides is a credible dose. 28mg of saffron at 3% crocins matches the range used in the sleep trials. Magnesium at 250mg elemental, delivered partly as L-threonate and partly as bisglycinate, is a sensible pairing of a well-absorbed form with a well-tolerated one.

This is the part of the review where most products fall over, and this one does not.

Testing and certification

NSF Certified for Sport®, which is the strictest of the mainstream independent certifications — it tests for banned substances and verifies that what is on the label is in the tub. Third-party tested for quality, with a Light Labs test in July 2026 covering 23 substances. Free of gluten, dairy, egg, peanuts and animal by-products, and non-GMO.

For a category with a long history of label inaccuracy, an NSF Certified for Sport mark is the single most useful thing on the packaging.

The price problem

$99 for a one-time purchase of 30 servings. $79 a month on subscription, dropping to $69 with an AG1 subscription. A 7-serving option works out at $3.57 a serving; 30 servings at $2.63. Free shipping, HSA/FSA eligible, and a 90-day money-back guarantee.

At $2.63 to $3.30 a night, this is one of the most expensive ways to take these ingredients. You could buy magnesium bisglycinate, L-theanine and ashwagandha separately for a fraction of it.

What the price buys is formulation, dosing you do not have to research, an NSF certification, and a single thing to do rather than four capsules to remember. Whether that is worth roughly $2 a night more than the component parts is a genuine judgement call, not an obvious yes or an obvious no. The 90-day window is long enough to find out properly.

What it does for snoring

Nothing mechanical, and this is where we differ from most coverage of sleep supplements.

Snoring is soft tissue vibrating in a narrowed airway. No ingredient in this panel widens an airway, reduces nasal resistance or changes palatal tone. If you snore, AGZ will not stop it.

What it may do is improve sleep onset and continuity, which makes a night with snoring in it less costly. That is worth something. It is not a remedy, and anything marketed to snorers as though it were is misleading you.

One genuine advantage for this audience: because it is melatonin-free, it avoids the concern that applies to sedating sleep aids. Melatonin, valerian at high doses, sedating antihistamines and prescription hypnotics can reduce upper airway muscle tone or blunt the arousal response that reopens a closing airway. That matters if you have — or might have — sleep apnea. The full explanation of why sedation and snoring interact badly.

Note that the blend does contain valerian and passionflower, so "melatonin-free" is not the same as "contains nothing calming." It is a meaningfully gentler profile, not a neutral one.

The verdict

Buy it if you want a properly dosed, independently certified, melatonin-free sleep formula and the convenience is worth the premium to you. The dosing and the NSF mark genuinely separate it from the shelf.

Skip it if you are price-sensitive — the same actives cost far less bought separately — or if you are hoping it will do something about the noise.

Common questions

Does AGZ contain melatonin?
No. It is deliberately melatonin-free, using magnesium, L-theanine, glycine, ashwagandha, saffron and a calming herb blend instead. That blend does contain valerian and passionflower, so it is gentler than a sedating aid rather than entirely neutral.
How much does AGZ cost per night?
$99 for 30 servings one-time, $79 a month on subscription, or $69 with an AG1 subscription — roughly $2.30 to $3.30 a night. It is expensive relative to buying the actives separately.
Is AGZ third-party tested?
Yes. It is NSF Certified for Sport, which verifies label accuracy and screens for banned substances, and it carries a July 2026 Light Labs test covering 23 substances.
Will AGZ help my snoring?
Not mechanically. Nothing in the formula widens an airway or reduces nasal resistance. It may improve sleep quality around the snoring, but it is not a snoring remedy.
