Private Label Magnesium Glycinate, 90 Capsules

Private Label Magnesium Glycinate for Calm, Recovery and Daily Mineral Lines

Private Label Magnesium Glycinate is a 90-count capsule supplement built on magnesium in its glycinate form, manufactured to order in a GMP-certified USA facility with flexible minimums and private label support from concept to finished goods. Brands receive a finished, bottled capsule product ready to carry their own label, artwork and SKU.

The product suits supplement brands, practitioner and clinical channels, sports and recovery lines, and retailers who want a recognizable single-mineral capsule rather than a complicated proprietary blend. Magnesium glycinate is the form buyers ask for by name, which means a brand launching this SKU is entering a category where consumer search demand already exists and the education work is largely done. Brands can position it around everyday calm, muscle recovery and nighttime routines, and it slots naturally alongside a sleep or stress range without competing with it.

What Is a Magnesium Glycinate Capsule?

A magnesium glycinate capsule is a mineral supplement in which magnesium is paired with glycine, an amino acid, and encapsulated in a fixed-count bottle. It differs from a generic magnesium capsule in that the form is named on the label rather than left as unspecified magnesium, which matters commercially: buyers comparing products on shelf and in marketplace listings filter by form, and an unspecified magnesium SKU loses those searches. This version is supplied at 90 capsules, a count that reads as a one-to-three month bottle depending on the serving a brand sets, and it is produced as a finished good, meaning BioB MFG handles the manufacturing, encapsulation and bottling and the brand handles the label and the market.

Market Demand

Magnesium sits inside two of the largest and fastest-moving parts of the supplement market. Grand View Research values the US dietary supplement market at USD 68.74 billion in 2025, rising to USD 131.08 billion by 2033 at an 8.5% CAGR, while Nutrition Business Journal puts the same US market at $74.15 billion in 2025 with 7.1% growth and $99.96 billion projected by 2029 — two firms, two methodologies, the same upward direction. Within that, the categories magnesium products are typically merchandised against are growing on their own terms: Precedence Research sizes the global sleep aid supplements market at USD 7.57 billion in 2025, reaching about USD 12.46 billion by 2035 at a 5.11% CAGR. The practical read for a brand is that magnesium is not a trend SKU that needs a category built around it; it is a staple line item with steady pull-through and repeat purchase behavior.

Private Label Opportunity

Magnesium glycinate is one of the strongest first SKUs for a brand entering minerals, because the ingredient is familiar, the format is simple, and margin is not eaten by an expensive multi-component formula. A brand can launch this as a standalone hero product, as the anchor of a three-SKU calm and recovery set, or as a practitioner-channel item sold alongside protocols. BioB MFG produces it as private label from concept to finished goods, so a brand with a label design and a distribution plan does not need to source raw material, qualify an encapsulator or manage a bottling line. Custom packaging is available, and formulation support is included if the brand later wants to move from single-mineral to a differentiated blend once the SKU has proven itself.

Competitive Landscape

On shelf this competes with three things: magnesium oxide and citrate capsules, which are cheaper per unit and usually sold on price; magnesium powders and drink mixes, which win on flavor merchandising but lose on portability and dosing precision; and multi-mineral or calcium-magnesium combination products, which spread the label across several minerals and dilute the magnesium story. A named-form glycinate capsule occupies the middle position that most brands want — specific enough to justify a premium against commodity magnesium, simple enough to explain in one line of packaging copy. BioB MFG also manufactures marine-sourced magnesium capsules and calcium-magnesium products, so a brand can build a tiered mineral range across sources and formats from one manufacturer with a single set of quality documentation.

Why Brands Choose This Formula

Brands choose this SKU because it is unambiguous. The form is named, the count is fixed at 90, the format needs no consumer explanation, and the manufacturing story is verifiable: made in the USA from globally sourced ingredients in a GMP-certified facility in Hauppauge, New York, with NSF, USDA Organic, Kosher and Halal certification routes available depending on the specification a brand needs for its channel. For retail buyers and marketplace listings, that combination of a named mineral form and a documented US facility is what turns a generic mineral bottle into a defensible product page.

Common Buyer Questions

What is a private label magnesium glycinate capsule?

It is a finished 90-count magnesium glycinate capsule product manufactured by BioB MFG and sold under your brand name rather than ours. You supply the brand, label artwork and packaging direction; we manufacture, encapsulate and bottle the product in our GMP-certified facility and deliver finished goods ready for your warehouse or fulfillment partner.

What format is this product?

It is a dry-fill capsule, supplied 90 capsules per bottle. There is no liquid carrier, no flavoring system and no powder scoop, which keeps packaging simple and makes the SKU straightforward to ship and merchandise alongside other capsule products in a line.

What form of magnesium does it use?

Magnesium in glycinate form, meaning the magnesium is bound with the amino acid glycine. We do not publish a standardized level on this page; the exact serving specification is confirmed on your batch documentation when a project is quoted, so your label copy matches your finished product.

What is your minimum order quantity (MOQ)?

Minimum order quantities vary by format. Liquid products under 8 oz start at 5,000 units; 8 oz and larger liquids start at 2,500 units. Capsule and tablet products have a minimum of 300,000 capsules or tablets total. Request a quote and we'll confirm exact MOQ and price breaks for your project.

Can the packaging and label be customized?

Yes. Custom packaging and label design are part of the private label program, covering bottle, closure, labeling and secondary packaging decisions. Brands can bring finished artwork or work with our team on the specification, and the same packaging approach can be carried across a multi-SKU line for shelf consistency.

Is the product manufactured to certified quality standards?

Yes. Production runs in our GMP-certified facility in Hauppauge, New York, and the product is made in the USA from globally sourced ingredients. NSF, USDA Organic, Kosher and Halal certification routes are available depending on your specification and target channel.

What wellness category does this product fit?

It fits the daily minerals category and is commonly merchandised into calm and stress-support, muscle recovery and nighttime routine ranges. Brands can position it around everyday mineral intake, occasional stress support and post-activity recovery, using structure and function language appropriate to their market and regulatory review.

Can BioB MFG manufacture this as a private label supplement?

Yes, concept to finished goods. That includes formulation support if you want to modify the specification, manufacturing and encapsulation, bottling, labeling and packaging, with flexible minimums and price breaks confirmed at quote. Request a quote to start a project.
