Private Label Mullein X Respiratory Capsules With NAC, 90 Capsules

Private Label Mullein X Respiratory Capsules With NAC, 90 Capsules for Botanical Plus Ingredient Brands

Private Label Mullein X Respiratory Capsules With NAC is a 90-count capsule product pairing a mullein-based herbal blend with NAC, manufactured to order under your own brand in a GMP-certified facility in Hauppauge, New York, from globally sourced ingredients, with flexible minimums and full formulation support.

This is the capsule member of the mullein range, and it is built for a different buyer than the liquids. Capsule customers want no taste, no measuring and no bottle to carry, and they count servings rather than ounces. A 90-count is a three-month supply at one capsule a day or a one-month supply at three, which makes it flexible enough to support either a subscription cadence or a bulk-value position. The formulation also does something the liquids do not: it combines a botanical blend with NAC, a defined non-botanical ingredient, which puts the product in the botanical-plus category that has grown fastest in specialty retail. It suits respiratory and immune-focused supplement brands, practitioner and clinical channels, and online sellers competing on ingredient panels.

What Is a Botanical Capsule With an Added Defined Ingredient?

It is a capsule supplement in which a botanical blend is combined with a specified, non-botanical ingredient, so that the panel carries both a herbal story and a named compound. That combination is harder to manufacture than either component alone, because botanical powders and defined ingredients behave differently in blending and encapsulation, and the finished capsule has to be uniform enough that every unit matches the specification. It is also more commercially useful than either alone. A pure botanical capsule competes on tradition; a single-ingredient capsule competes on price; a combination competes on formulation, which is the only one of the three that is hard for a competitor to copy quickly. This SKU is that third type, with NAC named alongside a mullein leaf based blend.

Market Demand

The most relevant measured figures for a capsule private label program are on the manufacturing side. Grand View Research values the global dietary supplement contract manufacturing market at USD 22.6 billion in 2025, reaching USD 58.9 billion by 2033 at a 12.8% CAGR from 2026 to 2033, which reflects how much of the industry's production has moved to specialist manufacturers rather than brand-owned plants. Fortune Business Insights values the global empty capsules market at $3.67 billion in 2025 and $3.91 billion in 2026, reaching $6.58 billion by 2034 at a 6.74% CAGR; that figure measures capsule shells as a component, not supplement revenue, and should be read as a proxy for how entrenched the capsule format remains. Capsules remain the default delivery form in the supplement aisle, and a botanical brand without one is limited to the customers who accept liquids.

Private Label Opportunity

Capsules are where a liquid-only herbal brand grows. They open the mainstream retail and marketplace channels where liquids underperform, they ship and store more efficiently, and they carry the serving-count math that comparison shoppers use. Private labeling this SKU means the blend, the encapsulation and the 90-count fill are already solved, so a brand's investment is in packaging, listing and positioning. The minimum for capsules is set in capsules rather than bottles, at 300,000 capsules or tablets total, which at 90 count spreads across a meaningful number of finished units and usually improves the per-unit economics compared with a small liquid run. We take a program from concept to finished goods, including bottle, closure, induction seal and carton specification.

Competitive Landscape

Three kinds of product compete for this shelf position. Single-botanical mullein capsules made from dried leaf powder are the cheapest and the most numerous, and they compete almost entirely on price and count. Standalone NAC capsules sell on the strength of a single recognizable ingredient name and are heavily commoditized. Multi-ingredient respiratory formulas exist but often hide their composition inside an unquantified proprietary blend. This product sits between them: a named botanical blend plus a named defined ingredient, which is a harder panel for a competitor to duplicate and an easier one for a brand to explain. Against the liquids in our own range, it captures the customer who will not take a dropper or a syrup at all.

Why Brands Choose This Formula

Brands choose this formula because it gives them a differentiated capsule without a development program. The panel names both a plant part and species and a defined ingredient, which supports a specific marketing story rather than a generic herbal one. The 90-count size works at multiple serving levels, so a brand can position it as either a value pack or a monthly supply. Capsule production runs alongside our liquid, spray, syrup and lozenge lines in the same GMP-certified facility, so a brand can build a full multi-format family under one quality system. Manufacturing is made in the USA from globally sourced ingredients, with NSF, USDA Organic, Kosher and Halal certifications available depending on the finished specification.

Common Buyer Questions

What is a private label capsule supplement?

It is a finished capsule product that BioB MFG formulates, blends, encapsulates, bottles and labels, and that you sell under your own brand name. We own the manufacturing; you own the brand, the artwork and the customer. It arrives as finished, sealed and labeled goods ready for distribution.

What format is this and how many capsules per bottle?

It is a two-piece capsule supplement supplied at 90 capsules per bottle. Capsules carry no liquid carrier and no alcohol question, which is why they travel and store better than the dropper and syrup formats in the same range and why they are usually the format a brand takes into mainstream retail.

What is NAC and how is it presented on the label?

NAC is N-acetyl cysteine, a defined ingredient included in this formulation alongside the mullein leaf based herbal blend. It appears on the panel by name. We do not publish amounts or standardized levels outside the finished product specification, which we provide with a quote, and brands should confirm the regulatory positioning of NAC for the specific market and channel they intend to sell into.

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. Bottle size and material, closure, induction seal, desiccant, label stock and finish, carton and case pack are all specifiable. We manufacture from your supplied artwork or help develop it, and we review label copy against the finished product specification before production.

Is the product manufactured to certified quality standards?

Yes. Encapsulation and packaging run in our GMP-certified facility in Hauppauge, New York, made in the USA from globally sourced ingredients. NSF, USDA Organic, Kosher and Halal certifications are available depending on the finished specification and the raw materials your program requires.

What wellness category does this product fit?

Respiratory and immune-focused supplement assortments, merchandised in the capsule set rather than with liquids. Brands can position it around the traditional use of mullein leaf in Western herbal practice combined with a named defined ingredient on the panel.

Can BioB MFG manufacture this as a private label supplement?

Yes. This is a private label product and capsules are a core capability here. We run programs from concept to finished goods with formulation support, and because we also manufacture the liquid, spray, syrup and lozenge versions of this botanical family, a brand can cover every format in the range with a single supplier.
