Capsules provide dietary supplement brands with a rapid route to market by encapsulating powders, granules, and micro-pellets without subjecting active ingredients to heat, compression, or binding agents. Moe’s Group manages the complete contract manufacturing process in-house, from formulation and encapsulation to secondary packaging and fulfillment. By consolidating these operations under a single quality management system, brands eliminate multi-vendor handoffs, streamline batch record documentation, and reduce supply chain risk.
This page walks through how our capsule supplement contract manufacturing works: shell chemistry, fill weight, release behavior, run capacity, and the route from first sample to a full production run. Read it with your own SKU in front of you, then send us the formula.
What Capsule Manufacturing Covers at Moe’s Group
Our capsule supplement contract manufacturing spans every step from ingredient list to finished pallet. Two questions set your scope: how much of that chain you hand us, and whether a capsule suits your actives.
Formulation Through Filling, Bottling and Fulfillment
Moe’s Group provides end-to-end capsule manufacturing services structured around a single quality-controlled workflow. Each production run follows a standardized four-phase process:
- Formulation & R&D. Formulators qualify raw materials, optimize powder rheology, and complete initial bench sampling.
- Precision blending. High-shear blenders achieve target content uniformity, backed by in-process analytical sampling.
- Encapsulation & finishing. Tamping-pin encapsulation machines fill shells to exact volumetric targets before pass-through polishing and weight sorting.
- Packaging & logistics. Automated bottling, induction sealing, labeling, and lot coding prepare finished goods for release.
Where Capsules Fit Against Tablets, Powders and Gummies
Solid oral dosage selection depends directly on formula volume, active stability, and organoleptic properties. Capsules are ideal for hygroscopic, heat-sensitive, or unpalatable ingredients, such as botanical extracts, probiotics, enzymes, and lipid formulations, because they require no heavy compression forces. Conversely, tablets are better suited for high-density formulations, while powders accommodate active dosages exceeding 5 grams.
Capsule Shell Options
The shell is the first package your formula touches. It governs label claims, moisture exposure, and where the capsule opens.
Vegetarian and Vegan Shells
Hypromellose (HPMC) and pullulan come from plant cellulose, so they carry vegan, halal, and kosher claims. Moisture sits near 4-6%, against 13-16% in gelatin. That gap protects probiotics, enzymes, and iron salts. Most custom veggie capsule formulations start here.
Gelatin Shells
Gelatin suits oil fills and cost-driven programs. Bovine and porcine collagen seal tightly and price below HPMC. Check your audience first: gelatin closes off vegan positioning.
Delayed and Enteric Release Shells
Delayed-release profiles protect acid-sensitive actives during gastric transit. Engineered HPMC shells resist gastric acid for approximately 45 minutes without secondary coating, making them suitable for targeted intestinal delivery. For full ileal or colonic release, enteric film coatings remain intact below pH 5.5 and dissolve cleanly between pH 5.5 and 6.8. As a bulk enteric-coated capsule supplier, Moe’s Group documents two-stage USP dissolution testing directly within every cGMP batch record.
Custom Capsule Formulation and R&D
Custom veggie capsule formulation starts from your target label. Our formulation and R&D team fits that dose into a swallowable shell.
Ingredient Selection and Excipient Choices
Functional excipients ensure uniform dosing and consistent machine performance. Formulators utilize rice hull concentrate as a natural bulking agent, magnesium stearate as an encapsulation pin lubricant, and silicon dioxide as a glidant to prevent powder bridging in the hopper. For clean-label custom veggie capsule formulation projects, our R&D team optimizes flow dynamics to minimize non-active additives without compromising run speeds.
Powder Flow, Blend Uniformity and Fill Weight
Automatic encapsulation machinery doses powders volumetrically; therefore, loose and tapped bulk density dictate total fill mass. A standard size 00 capsule shell accommodates a volume of 0.95 mL, yielding approximately 760 mg of fill weight at an average bulk density of 0.8 g/mL. Low-density botanical extracts may fill shell capacity prior to reaching active target dosage, requiring dry granulation or glidant modification. In-process statistical weight checks ensure batch-to-batch uniformity across every private label dietary capsule run.
Encapsulation Capacity and Run Speed
Our high-speed encapsulation services scale from pilot lots of a few thousand units to programs above one million units per month. Small runs test a claim before you buy inventory; large runs earn dedicated tooling. Coated lots keep that schedule, since your bulk enteric-coated capsule supplier and filler are one team.
Quality Systems and Testing
Every batch moves under a documented production and process control system, as 21 CFR Part 111 Subpart E requires. Specifications for identity, purity, strength, and composition carry through to a signed batch record. See our certifications.
Ingredient Identity and Potency Checks
Federal rule requires an identity test on every dietary ingredient. Supplier certificates count only after we qualify that supplier ourselves. We hold reserve samples for one year past shelf life, or two years from the last shipment.
Packaging and Labeling Options
Packaging travels with the shell. Moisture and light reach the capsule through it, so we stock PET, HDPE, glass, desiccant, and blister cards. Our private labeling team handles artwork, panels, and lot coding, so your private label dietary capsules arrive retail-ready.
How to Start a Capsule Program
Send three things: your formula, your annual volume, and your shell preference. We run a feasibility review, build a bench sample, then place a pilot batch on stability at 77 °F (25 °C). Our high-speed encapsulation services take over at release, and most private label dietary capsules ship within weeks.
Partner with Moe’s Group for Scalable Encapsulation Services
Transitioning a capsule formulation from concept to commercial production requires clear technical alignment. Our engineering and manufacturing teams evaluate your formula parameters, including shell chemistry, fill weight, and release kinetics, to provide a transparent quote and operational timeline. Whether launching a new SKU or transferring a high-volume product line, domestic manufacturing at Moe’s Group delivers consistent batch quality and supply chain control.
