Magnesium glycinate vs Beam Dream — capsules, citrate and the cocoa tax

Magnesium supplements hide behind ‘3-in-1’, ‘clinical sleep blend’ and influencer hot chocolate. The SDS or supplement facts panel names one magnesium compound. That salt drives absorption, gut tolerance and price — not the flavour.

Citrate is inexpensive and osmotic (can move the bowels). Bisglycinate is a chelated form often marketed for evening use. Chloride is what ‘magnesium oil’ sprays use. They are not interchangeable on dose or job.

Beam’s sleep powder is a ritual product: cocoa, stevia, coconut milk powder, plus magnesium citrate, L-theanine and small botanical doses. The teardown maths shows most of the pack price is packaging and flavour, not exotic actives.

If you like the drink, fair enough. If you want the chemistry without £2+ per cup, bisglycinate plus theanine in plain milk or tea is the same stack minus the marketing.

The Magnesium Glycinate 3-in-1 tub is bisglycinate in capsules with B6 and D3 on the label — closer to the gentle salt in Beam’s dupe stack than Beam’s own citrate-forward powder.

Compare elemental magnesium per day, not capsule count. A 60-capsule IG tub is often weeks of supply; 500 g bisglycinate powder is months. Capsules win on convenience; bulk wins on cost per milligram.

Typical food-supplement pattern: 200–300 mg elemental magnesium as bisglycinate with an evening meal. Optional: 200 mg L-theanine if you want the Beam-style wind-down — buy it as a separate powder.

Reduce dose if stools loosen. This is not a treatment for insomnia or anxiety. Speak to a GP or pharmacist if you take heart medicines, diuretics or have kidney issues.
