Label teardown
What the pack promises versus what the label chemistry actually is.
The marketing claim
“Supports muscle relaxation, sleep and stress”
The chemical reality
Capsules of magnesium bisglycinate with a little B6 and D3 marketing — the same gentle Mg salt Beam’s dupe stack uses, without the £2.40 cocoa cup. Buy bisglycinate powder or tablets by elemental magnesium on the label. Food supplement comparison, not a sleep medicine.

The Marketing Claim & The Catch
A 60 capsules (6–12 week supply) pack of Nutrition Geeks Magnesium Glycinate 3-in-1 typically retails around £14.00 in wellness & supplements. That is a UK shelf-price snapshot for the maths on this page — not a live shop quote or a manufacturer RRP. Listings, sizes and deals move. The marketing line is that you are buying a finished lifestyle product, not a weighed chemical.
On the pack: Supports muscle relaxation, sleep and stress; Highly absorbable glycinate form; and With vitamin B6 and D3 for synergy.
The catch: Capsules of magnesium bisglycinate with a little B6 and D3 marketing — the same gentle Mg salt Beam’s dupe stack uses, without the £2.40 cocoa cup. Buy bisglycinate powder or tablets by elemental magnesium on the label. Food supplement comparison, not a sleep medicine.

Proprietary Blend & Dosage Breakdown
The labelled active is Magnesium bisglycinate (elemental magnesium) at 20%. Everything else in the pack is rice flour, b6 and d3 as ‘3-in-1’ extras.
At 20% 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.

The Active Chemical Alternative (Dupe Stack)
The dupe stack is Magnesium bisglycinate powder or tablets (elemental Mg labelled) at 20% bulk. Indexed as CAS 14783-68-7, formula C4H8MgN2O4. Buy it as 500 g powder (~100 g elemental Mg depending on grade) for around £14.00 from Amazon UK.
Working strength: 200–300 mg elemental Mg daily with food (follow the tub). Indicative cost £0.14 per diluted litre — 65% below a typical branded pack on a per-litre basis, before you reuse leftover bulk.
Mix or dose as a food supplement using the steps below. Do not exceed labelled amounts, and read the supplier’s information. This is not medical advice.
- This is a food-supplement comparison, not a medicine and not a treatment for insomnia or anxiety. Reduce dose if it loosens stools.
- Weigh bisglycinate for elemental magnesium on the label — many stacks target 200–300 mg elemental Mg in the evening with food.
- Optional: 200 mg L-theanine if you want the Beam-style night drink — buy separately.
- 500 g of bisglycinate is many months versus a 60-capsule IG tub.

Active ingredient and cheaper alternative — FAQ
Is this the same as Beam Dream powder?
Same core salt family: bisglycinate is gentler than citrate. Beam sells flavoured powder with citrate on the label plus cocoa; Nutrition Geeks sells capsules. The bulk stack is unflavoured bisglycinate — optionally add your own theanine if you want a night-time drink.
How much elemental magnesium is in each capsule?
Many ‘glycinate 3-in-1’ tubs are 80–150 mg elemental magnesium per capsule. Read the back for elemental Mg, not just ‘magnesium bisglycinate’ milligrams.
How do you mix the Magnesium Glycinate 3-in-1 dupe stack?
This is a food-supplement comparison, not a medicine and not a treatment for insomnia or anxiety. Reduce dose if it loosens stools. Weigh bisglycinate for elemental magnesium on the label — many stacks target 200–300 mg elemental Mg in the evening with food. Optional: 200 mg L-theanine if you want the Beam-style night drink — buy separately. 500 g of bisglycinate is many months versus a 60-capsule IG tub.
