Magnesium Citrate Contract Manufacturing, From Salt to Retail Bottle

Magnesium citrate is a well-absorbed magnesium salt used in muscle, relaxation and sleep formulas, so buyers compare elemental magnesium content, salt form and serving size before price. ZOOMSHEAL Health runs dedicated mineral lines in our GMP-certified Guangzhou facility, where we control salt sourcing, blending, filling and packaging to your approved specification.

We produce magnesium citrate capsules and tablets at 100 mg, 200 mg and 400 mg elemental magnesium, single-serve powder sticks and jars, and pectin gummies. Formulas can combine it with vitamin D3, K2 or B6 and with glycine or taurine. Clients include sports and sleep brands, pharmacy private label ranges and DTC sellers shipping to the US and EU.

What Sets Our Magnesium Citrate Production Apart

High-Absorption Magnesium Salt Sourcing
We source food-grade magnesium citrate and can blend it with other well-absorbed salts such as magnesium bisglycinate and magnesium L-threonate when a formula calls for a broader magnesium profile.
Elemental Magnesium Dosing
Every formula is built around elemental magnesium content, from 100 mg to 400 mg per serving, so your label claim and serving size match the finished capsule, tablet or powder within specification.
One Factory, Four Dosage Forms
Hard capsules, coated tablets, powder sticks and pectin gummies are produced in-house. Magnesium citrate pairs with vitamin D3, K2, B6, glycine or taurine under one MOQ and one quality file.
Clean Label and Vegan Options
We formulate with HPMC vegan capsules and pectin gummies, and can leave out titanium dioxide, artificial colours and common allergens. Sugar-free, organic and halal-ready programs use certified raw materials.

Our Magnesium Citrate Contract Manufacturing Process

01
Consultation & Brief
We review your element target, salt form, dosage form and market, then recommend a magnesium citrate formula and format that is feasible and cost-effective for your volume.
02
Formula & Pilot Sample
Our team sets the salt, elemental magnesium level, co-ingredients and overage, then produces a pilot batch so you can check appearance, taste and weight before approval.
03
Quotation & Approval
When the pilot is approved we fix the elemental magnesium level and finished specification, agree MOQ, bottle format and lead time, and issue the formal quotation and proforma invoice.
04
Blending & Production
Magnesium citrate is blended with co-ingredients under controlled humidity, then filled, pressed or moulded on dedicated mineral lines with in-process weight and content checks.
05
Quality Control & Testing
Every batch is tested for magnesium content, uniformity, disintegration, heavy metals and microbiology, and released only after the certificate of analysis is approved.
06
Packaging & Export Shipping
Capsules, tablets, sachets and gummies are then bottled or jarred, induction-sealed, labelled to your artwork and cartoned, and documented for air, sea or express delivery.

Quality Control for Magnesium Content

Elemental magnesium content is easy to overstate and hard to prove, so our quality programme focuses on identity, assay and stability. Every incoming magnesium salt is verified against its certificate of analysis, and each finished batch is tested for magnesium content, weight uniformity, disintegration, moisture and microbial safety.

The plant is GMP-certified in Guangzhou Huadu and complies with FDA, NSF and cGMP standards, with HACCP controls spanning salt intake, blending, filling and packing. Stability work, accelerated and real-time, supports both the shelf life and the elemental magnesium claim printed on your finished bottle.

Magnesium Citrate Manufacturing FAQ

What is the minimum order quantity for custom magnesium citrate supplements?+
Magnesium citrate capsules and tablets begin at 3,000 bottles, gummies at 20,000 pieces, powder sticks at 10,000 sachets and bulk powder at 25 kg. A first small-batch trial is negotiable if you are validating a new mineral SKU.
Can you manufacture magnesium citrate under my own brand?+
Yes. We are a private label and OEM/ODM manufacturer, so your brand appears on the label, carton and certificate of analysis while we supply the salt, dosage form and packaging. Your custom magnesium formula is never resold to another brand.
How long does magnesium citrate production take?+
Figure on 4 to 6 weeks from formula and artwork sign-off for capsules, tablets or powder sticks, and 5 to 7 weeks when pectin gummies are involved. Salt sourcing, blending, filling, release testing and export packing all sit inside that window.
How much does custom magnesium citrate manufacturing cost?+
Price per unit is driven by the salt form, elemental magnesium level, dosage form and pack. A straightforward 100 mg citrate capsule at scale is competitively priced, while higher dosing and premium amino acid chelates cost more per unit. Send the spec and volume for a quote.
Can you combine magnesium citrate with other ingredients?+
Yes. Magnesium citrate is commonly paired with vitamin D3, K2 and B6, and with glycine or taurine. We can also blend it with other magnesium salts such as bisglycinate, L-threonate and oxide to build a full-spectrum magnesium formula under one label.
Do you provide packaging and label design?+
We stock bottles, jars, sachets and cartons for mineral lines and can either create your label artwork or print from supplied files. Dielines, barcodes and the compliant supplement wording, including the standard FDA disclaimer, are prepared so the product lands retail-ready.
Which certifications does your factory hold?+
Magnesium citrate is made in a Guangzhou facility certified to GMP and cGMP and operating HACCP plus ISO 22000, while meeting FDA and NSF standards. Each batch leaves with a specification sheet and certificate of analysis.
Can you help with shipping, customs and payment?+
Exports travel with a commercial invoice, packing list, certificate of analysis, certificate of origin and any required health certificates, by air, sea or express. New orders normally open with a 30% deposit and close with the 70% balance before dispatch, by T/T or an agreed method.
