The Marketing Claim & The Catch
A typical 30-serving pouch pack of Beam Dream Nighttime Sleep Powder is about £72.00 in wellness & supplements. That is a snapshot, not a live Amazon price — listings, sizes and deals move. The marketing line is that you are buying a finished lifestyle product, not a weighed chemical.
On the pack: Clinical sleep blend without next-day grogginess; and Supports healthy recovery and mental wind-down.
The catch: Over £2.40 a cup for cheap, gut-irritating magnesium citrate and micro-dosed botanicals. Bisglycinate plus free-form L-theanine is the same night-time stack without the cocoa tax. Food supplement comparison, not a medicine.

Proprietary Blend & Dosage Breakdown
The labelled active is Magnesium citrate, L-theanine, reishi, melatonin at 30%. Everything else in the pack is cocoa powder, coconut milk powder, stevia.
At 30% active, most of what you pay for is carrier and packaging. The brand is selling convenience, fragrance and a label — not a uniquely potent molecule.
This is a food-supplement comparison, not a medicine. Proprietary blends, gummies and resins make it hard to see milligram-level doses. The teardown below uses the labelled active and a bulk equivalent you can weigh or capsule yourself.

Active ingredient and cheaper alternative — FAQ
What is the active ingredient in Beam?
Beam Dream Nighttime Sleep Powder is labelled as Magnesium citrate, L-theanine, reishi, melatonin at 30%. The carrier is Cocoa powder, coconut milk powder, stevia. Pack size: 30-serving pouch. The bulk equivalent we index is Magnesium bisglycinate + free-form L-theanine + tart cherry extract (CAS 14783-68-7 / 3081-61-6).
Is Magnesium bisglycinate + free-form L-theanine + tart cherry extract safe on the intended surface?
Used at the listed working strength (2.5 g magnesium bisglycinate (300 mg elemental Mg) + 200 mg L-theanine in 200 ml warm oat milk), the dupe is the same chemistry as the branded pack for food-supplement use as labelled — not as a medicine. That is not a blanket all-clear: read the supplier SDS, wear the listed PPE, keep acids away from hypochlorite, and follow UK HSE/COSHH rules. Wellness teardowns are supplements, not medicines.

Working strength: 2.5 g magnesium bisglycinate (300 mg elemental Mg) + 200 mg L-theanine in 200 ml warm oat milk. Live shop prices move.
How do you mix the Dream Nighttime Sleep Powder dupe stack?
This is a food-supplement comparison, not a medicine. It will not treat insomnia. Whisk 2.5 g unflavoured magnesium bisglycinate and 200 mg L-theanine powder into 200 ml warm milk or chamomile tea, 45 minutes before sleep. Bisglycinate is gentler on the gut than citrate. Start on the low side if you are new to magnesium.
