Sleep Magnesium Powder is a private-label powder stick delivering Glycine, Magnesium Glycinate, L-Theanine per serving. Additive-ready for your brand. Available for private label from MOQ 1,000 units.
An L-theanine sachet under a magnesium-led name
Sleep Magnesium Powder is described in its own catalogue copy as a glycine, magnesium glycinate and L-theanine combination, though the structured formula table currently confirms L-theanine alone. As with other partly-confirmed SKUs in this range, the magnesium-led name and the confirmed formula table are two separate facts worth checking against each other before a brand locks its own label copy.
The format is a single-serve sachet stirred into water or a drink rather than swallowed as a capsule — suited to an evening routine built around a drink.
Where a magnesium-named sachet sits in a sleep-and-relax range
Sleep & Relax serves brands building adult sleep, calm and evening-routine ranges, and the powder-sachet format gives that range a mixed-drink evening option alongside its drops, strips and jelly sticks. Magnesium Powder sits in the same range as the format's other magnesium-adjacent sachet, itself with its own partly-confirmed formula table.
Sleep + L-Theanine Strips carries the identical confirmed active, L-theanine, into the catalogue's oral-strip format instead of a sachet. A brand comparing the two is comparing the same confirmed ingredient across a mixed-drink and a dissolving-strip delivery.
Personalising and ordering the Sleep Magnesium Powder formula
Personalization covers approved flavour on this exact formula — project-specific personalisation, not a formula change. Flavour matters on a mixed sachet since it is drunk rather than swallowed as a capsule, so the taste is fully present in the final drink.
Confirming the glycine and magnesium glycinate content within the structured formula table, changing the active mix, or introducing a new claim moves the project into Formula Adaptation instead. Label claims plus market compliance remain the brand owner's responsibility throughout.

Frequently asked questions
Can I request a sample before ordering?
Ready-to-ship samples of selected production-ready formulas are on the Samples page while in stock — not every product has one. To test a different flavour, colour or shape, configure this product; where the product offers a Personalization Sample, you can order one of that exact configuration at the review step. Samples are paid upfront, and you do not need an account to start.What is the MOQ?
Minimum order quantities for Sleep Magnesium Powder are set up front, not quoted: from 3,000 boxes in powder stick. Larger runs of the same formula stay Private Label, as a volume quote. A change to the formula itself is different: Formula Adaptation production starts from 60,000 sticks per SKU; the minimum is fixed for each format.What packaging is available?
Packaging for this format: Powder stick. Standard pack size for this product is 10 powder stick per pack. More options open up at higher volumes, and you pick your pack when you build your product.Can I customise flavour, colour or shape?
Yes — the flavour, colour and existing shape options this format supports are choices you make when you build your product, at the same unit price and with no setup fee. Where the product offers a Personalization Sample, you can test them first. The formula stays the same. Changing the actives or the dosage means Formula Adaptation instead, which starts higher; claims work is a Custom Project.Who produces and supplies this product?
