This guide compares Beam Dream, Moonbrew, and Med-Lock’s PM-02™—reviewing formulation, delivery, and price so you can choose a sleep supplement based on what matters to you.

What Makes a Sleep Supplement Actually Work?

Before getting into the different brands and products, it helps to understand what separates effective sleep support from expensive placebos. Getting good sleep isn’t just about being knocked out—it’s about supporting the biological processes that happen while you rest.

Melatonin Dosing

Most people have heard of melatonin as a supplement, but did you know that your brain naturally produces about 0.1mg to 0.5mg of melatonin each night?¹ It would make sense for sleep aids to provide this natural dose in their products. But the reality is that many supplements use 3mg, 5mg, or even 10mg of melatonin, which far exceeds what we’re used to.

While higher doses can help some people fall asleep more quickly, many individuals experience morning grogginess because of it.

🔬 Science Translation: Think of melatonin like a dimmer switch, not an on/off button. Your body uses small amounts to signal “time for sleep.” Higher doses work for some people; others find lower doses more effective with fewer side effects.

Delivery Timing

You know when you fall asleep just fine… and then your brain schedules an unsolicited 2:17 a.m. meeting? 🫠 That’s why “falling asleep” and “staying asleep” need different support. 

Sleep happens in phases, repeatedly cycling through light sleep, deep sleep, and REM (rapid eye movement—when you’re dreaming) all night. Those transitions are where some people get bumped awake. 

So a supplement that releases everything at once can be helpful for falling asleep. But if the effects fade a few hours later, you may wake up right as your body shifts into its next stage. For people who tend to wake mid-night, longer-lasting support—or a formula designed to release in phases—can feel more aligned with how sleep actually unfolds.

The Gut-Brain-Sleep Axis

Sleep isn’t just a brain thing. Your gut microbiome also plays a role in regulating sleep-wake cycles.² One reason is that gut microbes are involved in producing (or influencing) neurotransmitters like GABA, which helps calm the nervous system and ease stress.² That’s why some sleep formulas are now designed with this gut-brain connection in mind.

Key Differences at a Glance: Beam Dream vs. Moonbrew vs. Med-Lock’s PM-02

A Closer Look: Med-Lock’s PM-02™ Sleep + Restore

Med-Lock approaches sleep through the lens of the gut-brain axis. PM-02™ is designed as a “Sleep + Restore” formula to help you fall asleep, stay asleep, and recover overnight.

The 2-in-1 Approach: Support for You and Your Microbiome

PM-02™ uses ViaCap® technology—a capsule-in-capsule delivery system—to separate ingredients and release them at different points in the digestive tract.

The outer capsule releases bioidentical melatonin and ashwagandha in your stomach to help you drift off. The inner capsule protects sensitive prebiotics and postbiotics, delivering them later to your gut microbiome.

Bioidentical Melatonin

PM-02™ uses 0.5mg of bioidentical melatonin. “Bioidentical” means the melatonin is structurally identical to what your brain naturally produces.

💊 The formula features a dual-phase release:

• Instant Release: Helps reduce sleep latency (the time it takes to fall asleep).
• Extended Release: Continues over an average of 7 hours to support staying asleep through the night.³

Clinically Studied Shoden® Ashwagandha

This may not come as a surprise, but stress can disrupt sleep. PM-02™ includes 120mg of Shoden® ashwagandha, a clinically studied extract shown to support improvements in sleep quality and time spent asleep.⁴

Gut-Brain-Sleep Support: GABA and Prebiotics

The inner capsule delivers GABA (a calming neurotransmitter produced by fermentation) and a prebiotic fiber blend to your gut. This supports the gut-brain axis, which research suggests plays a role in sleep regulation.⁵

💡 Pro Tip: If stress and racing thoughts keep you up, the combination of ashwagandha (for cortisol balance) and GABA (for calming the nervous system) addresses both.

Considerations for Med-Lock’s PM-02™

PM-02™ is delivered in a capsule format. So, that may not work for anybody who has a preference for a warm drink ritual before bed. Med-Lock’s sleep supplement also contains melatonin, which some people prefer to avoid.

A Closer Look: Beam Dream

Beam Dream Powder is a hot cocoa-style supplement designed as a bedtime ritual. The brand markets itself on the cozy experience of drinking something warm before bed.

Formulation Overview

Beam has built a following around the idea that your sleep routine should feel like self-care. 💅

The product is positioned as an indulgent treat that happens to help you sleep. For people who enjoy the ritual of making something warm before bed, this approach has appeal.

Key Ingredients and Doses

• 3mg Melatonin: A common commercial dose, though higher than what the body naturally produces (~0.5mg)
• Reishi Mushroom: An adaptogen traditionally used for relaxation
• Magnesium: Supports muscle relaxation
• Nano Hemp: The flagship product contains hemp (CBD), though they offer a hemp-free version
• L-Theanine: An amino acid that promotes relaxation

Benefit Claims

Beam claims to help you “fall asleep, stay asleep, and wake up refreshed.” They cite that 98% of participants in their internal study fell asleep faster. The brand emphasizes making bedtime something to look forward to.

Delivery Format

Beam Dream comes as a powder that you can mix into hot water or milk. This kind of ritual requires some preparation time (and sometimes a frother) right before bed. 

Considerations for Beam Dream

Beam Dream is the most expensive option at $65/month. At 3mg of melatonin, some people may experience morning grogginess—though others tolerate it well. It contains sweeteners (usually monk fruit/erythritol) and flavorings.

A Closer Look: Moonbrew

Moonbrew positions itself as a “superfood sleep cocoa” and is the melatonin-free option in this comparison. It focuses entirely on herbal and mineral support.

Formulation Overview

Moonbrew appeals to people who want sleep support without any melatonin. The brand emphasizes plant-based adaptogens and highly absorbable forms of magnesium. For those who’ve had negative experiences with melatonin or prefer to let their body regulate its own production, Moonbrew offers an alternative.

Key Ingredients and Doses

Moonbrew builds its formula around calming minerals and herbs:

• Magnesium Blend: Uses Magnesium Glycinate and Taurate, which are highly absorbable forms
• Adaptogen Blend: Includes Reishi, Chamomile, and Valerian Root
• L-Theanine: For relaxation
• 0mg Melatonin: The defining feature for those who want to avoid it

Benefit Claims

Moonbrew claims to “quiet the mind” and support sleep without hormones. The brand emphasizes its status as a “natural” alternative to melatonin-based aids.

Delivery Format

Like Beam, Moonbrew is a powder mix (hot cocoa flavor). It typically uses natural sweeteners like monk fruit.

Considerations for Moonbrew

Moonbrew is a mid-range option at ~$48/month. Relying solely on magnesium and herbs works well for some people, though it may not be strong enough for those with significant trouble falling asleep. The lack of melatonin means it doesn’t directly signal “time to sleep” to your circadian clock—which is either a benefit or limitation depending on your preferences.

How to Choose: Beam Dream vs. Moonbrew vs. Med-Lock PM-02

Choose Beam Dream If:

• You love the ritual of drinking hot cocoa before bed
• You tolerate higher doses of melatonin (3mg) well
• You want a product that includes hemp/CBD
• You prefer a powder over pills

Choose Moonbrew If:

• You’d like to avoid melatonin
• You want a magnesium-heavy drink with highly absorbable forms
• You enjoy herbal cocoas and want “superfood” ingredients without hormonal support
• You prefer a powder over pills

Choose Med-Lock’s PM-02™ If:

• Higher doses of melatonin have caused grogginess or haven’t worked for you.
• You want to support your gut-brain axis alongside sleep.
• You want clinically studied ingredients like Shoden® ashwagandha.
• You prefer a capsule over preparing a drink.
• Budget is a factor—it’s the most affordable option at $34.99/month.

The Key Insight

Each of these sleep supplements represents a different philosophy:

Beam Dream prioritizes the ritual experience—a warm, cozy drink before bed that makes sleep feel like self-care. It includes 3mg melatonin and hemp/CBD for those who want that combination. Moonbrew prioritizes melatonin-free support with highly absorbable magnesium and adaptogens. It appeals to those who prefer herbal approaches over hormonal ones.

Lastly, Med-Lock’s PM-02™ prioritizes precision dosing with 0.5mg bioidentical melatonin, clinically studied ashwagandha, and gut-brain axis support via dual-release delivery. It appeals to those interested in the microbiome connection to sleep.

The “best” choice for you depends on your priorities, like routines, melatonin preferences, ingredient philosophy, or precision science. ✨

Frequently Asked Questions (FAQs)

What Supplements Help You Fall Asleep Faster?

Med-Lock’s PM-02™ and Beam Dream both contain melatonin, which signals your brain that it’s time to sleep.

Moonbrew is melatonin-free, relying on magnesium and adaptogens for relaxation—which can help with winding down but works differently than direct melatonin signaling. PM-02™’s quick-release outer capsule is designed to reduce sleep latency.

Do Sleep Aids Make You Groggy in the Morning?

They can, depending on the person and the melatonin dose.

Higher doses of melatonin (like the 3mg in Beam Dream) are more likely to cause morning grogginess for some people. Med-Lock’s PM-02™ uses a 0.5mg dose, which may reduce this effect. Moonbrew is melatonin-free, so hormonal grogginess isn’t a concern—though individual reactions to valerian can vary.

Can I Take Sleep Supplements Every Night?

Yes—all three products (PM-02™, Beam Dream, and Moonbrew) are marketed as non-habit forming.

PM-02™ is formulated for daily use to help support circadian rhythm and microbiome health over time. Consistency often matters for sleep support.

Which Sleep Supplement Is Best for Better Sleep?

It depends on your specific sleep challenges and preferences.

• If you enjoy a bedtime ritual and tolerate melatonin well, Beam Dream offers a cozy hot cocoa experience with hemp/CBD.
• If you want to avoid melatonin entirely, Moonbrew provides magnesium and adaptogen support.
• If you want precision dosing, extended-release melatonin, and gut-brain support, Med-Lock’s PM-02™ offers a different approach at the lowest price point.
