AGZ review: my honest thoughts after 30 nights

A nightly ritual that feels as intentional as my morning AG1 Next Gen routine, and one that’s actually helped me unwind and wake up feeling more rested.

AGZ is the latest product from the team behind the hugely popular greens powder supplement, AG1, which I’ve taken for years, and recently moved on to their new formula, AG1 Next Gen. I shared my first 30 days experience here.

If AG1 is the foundation for my mornings, AGZ is their answer to evenings.

It’s a melatonin-free nightly drink made with clinically studied adaptogens, herbs, and minerals, designed to help your body wind down, support sleep quality, and help you wake up feeling more refreshed.

Each serving includes 250mg of highly bioavailable Magtein® magnesium L-threonate, which provides over half your daily value, alongside saffron, ashwagandha, valerian, and L-theanine.

All ingredients are included at research-supported amounts, which is a big deal for supplements in this category. The key here is that AGZ isn’t trying to override your natural sleep cycle, it’s meant to work with it.

Why I take AGZ

Like most people balancing training, work, and family, I often struggle to “switch off” at night.

My mornings feel locked in thanks to AG1, but my evenings can easily slip into a longer than expected session in front of the TV, restless scroll on my phone, and eventually lying awake thinking about tomorrow’s work schedule.

I’m always looking for products to help improve my sleep quality.

That’s where AGZ has made the biggest difference, by adding it into my evening routine, usually after settling our son, and loading the dishwasher, I’m cuing my body that it’s time to wind down.

AGZ recommends drinking it 90 minutes before you intend your head to hit your pillow. It’s become as much a ritual as brushing my teeth.

And the synergy of AG1 in the morning and AGZ at night feels intentional, a full-circle approach to supporting health around the clock.

What’s in AGZ?

AGZ combines a handful of well-researched ingredients into one scoop:

  • Magtein® magnesium L-threonate – supports sleep quality and cognitive health
  • Saffron – studied for mood support and its role in enhancing sleep quality
  • L-theanine – calming amino acid that helps the nervous system relax
  • Valerian root – long-studied herb to promote relaxation before bed
  • Ashwagandha – adaptogen that helps the body manage stress and support relaxation

Notably, AGZ is:

  • Melatonin-free
  • NSF Certified for Sport®
  • Free from gluten, dairy, added sugar, and artificial sweeteners

That last point matters, it helps me wake feeling refreshed the next morning.

Taste and mixability

AGZ comes in three flavors: Chocolate, Chocolate Mint, and Mixed Berry.

AGZ flavors

I have been using the Chocolate and Chocolate Mint flavors, both of which I enjoy drinking.

I’ve been leaning toward Chocolate Mint more though, mixed with room temperature water, or warm milk and frothed.

It tastes like a light, earthy cocoa with a hint of herbal depth that reminds me this is more than a sweet treat like hot chocolate, for example.

It’s not supposed to be a dessert, it’s a healthy ritual, so don’t expect an indulgent taste, instead, enjoy the pleasant and unusual one.

I like that you can drink it either warm or cold. Warm feels more like a bedtime tea; cold is refreshing after a hot evening run. Either way, it mixes smoothly with no chalky residue.

To use it, you simply add 1 packet of AGZ to 4–6 ounces of your preferred liquid, froth or stir until smooth, and drink 90 minutes before bed.

How I feel after 30 nights

Sleep is personal, but here’s what I’ve noticed since making AGZ part of my nightly routine:

  • A calmer transition into bedtime and less of that “busy mind” feeling in the evenings
  • Sleep that feels more restful and restorative
  • I wake feeling refreshed in the morning
  • A sense of consistency, AGZ has become a cue that it’s time to wind down

The difference isn’t dramatic like flipping a switch, so don’t go expecting a silver bullet, it’s really about adding an extra habit, and making smaller changes daily, just like I learned from September’s Book Of The Month, Atomic Habits.

It’s more like turning down the volume on the day, and waking with a little more clarity the next morning.

Side effects?

I haven’t experienced any side effects with AGZ, though, as with any supplement, your body may take a few days to adjust.

Since it’s melatonin-free, it fits smoothly into my routine without any next-day heaviness.

If you’re on medication or have concerns, it’s always smart to check with your doctor first, and always listen to your body.

How much does AGZ cost?

AGZ costs $79/month on subscription (or $89 as a one-time purchase), which includes 30 packets/servings in a box container, like you see in the photo above.

That breaks down to around $2.60 a night, which less than most other nightcaps, and far better for me.

The subscription is flexible and can be canceled anytime.

Is AGZ worth it?

If you already use AG1 in the morning, AGZ is its natural counterpart for the evening. For me, it’s created a small but meaningful ritual shift, not just treating sleep as an afterthought, but as an intentional part of recovery and long-term health.

It won’t replace good daily habits like eating a healthy diet, spending time outdoors, regular exercise, leading a stress-free lifestyle, etc, that all improve sleep quality, but it can certainly support it.

And for anyone who finds themselves with a busy mind at night or waking less refreshed than they’d like, AGZ is worth trying.

Yes, I’ll continue to use it. In fact, AGZ has now joined fatty15, Omega-3, and AG1 Next Gen as the only supplements I take daily.

Where to buy AGZ

You can buy AGZ directly from drinkAG1.com. Use my link to get their trial offer on your first subscription order.

Like AG1, the subscription can be canceled at any time, so I’d recommend starting there to save some money.
