The right dosage form can make or break your supplement brand.
If you have ever worked with a contract manufacturer, you know that choosing the wrong format — even with a perfect formula — leads to poor consumer acceptance, high return rates, and lost shelf space. So how do you decide?
As the OEM/ODM team at Dongying Zuoning Biotechnology Co., Ltd., we help global brands select optimal delivery forms every day. Here is our practical guide.
Hard Capsules (Two-Piece Hardshell)
What they are: Two-piece shells (body + cap) typically made from bovine gelatin or plant-based HPMC (pullulan). The formula — powder, granules, or pellets — is filled into the body and sealed.
Best for:
- High-dose, bioavailable ingredients (e.g., CoQ10, curcumin with piperine, probiotics)
- Multi-ingredient formulas that need to be kept separate (dual-chamber capsules)
- Clean-label positioning — capsules have fewer excipients than tablets
Key OEM considerations:
- Fill weight matters. Capsules come in standard sizes (00, 0, 1, 2, 3). Work with your manufacturer to match fill volume to your dose requirements.
- HPMC vs gelatin. If targeting vegan or halal markets, HPMC (plant-cellulose based) is non-negotiable. Note: HPMC capsules are slightly more expensive and have marginally different moisture barrier properties.
- Opaqueness. If light-sensitive ingredients are involved, opaque capsules or two-tone options are available.
Soft Capsules (Softgels)
What they are: One-piece hermetically sealed capsules — typically gelatin-based — containing a liquid or semi-solid fill (oil, suspension, or emulsion).
Best for:
- Oil-soluble ingredients: Omega-3 (fish oil, krill oil), Vitamin E, CoQ10 (ubiquinol), Vitamin D3
- Ingredients where bioavailability is dramatically improved in lipid-based delivery (e.g., certain herb extracts)
- Premium brand positioning — softgels feel high-end
Key OEM considerations:
- Temperature sensitivity. Softgels are sensitive to heat and humidity. Shipping to tropical climates requires specific packaging (e.g., blister packs with desiccants).
- Fill compatibility. Not all ingredients are compatible with the gelatin matrix. Your manufacturer needs to run compatibility trials before scaling up.
- Vegan alternatives are limited but improving (plant starch, seaweed-based, pectin softgels). Expect higher MOQ and cost.
Gummies (Chewy Supplements)
What they are: Gelatin or pectin-based chewy matrices, typically poured into mold cavities and individually shaped.
Best for:
- Consumer compliance — especially for children, seniors, or anyone who dislikes swallowing pills
- Beauty-from-within positioning (collagen, biotin, hyaluronic acid gummies)
- Retail shelf differentiation — gummies sell on visual appeal
Key OEM considerations:
- Pectin vs gelatin. Pectin-based gummies are vegan-friendly and have a slightly different texture (more jelly-like). Gelatin gummies are firmer and more traditional.
- Acid and heat sensitivity. Many active ingredients (probiotics, certain vitamins) degrade under the heat of the gummy manufacturing process. Discuss stability with your OEM partner early.
- Sugar vs sugar-free. Sugar-free gummies use sugar alcohols (maltitol, sorbitol) or stevia. Note regulatory limits on maximum daily intake of sugar alcohols in some markets.
- AOAC specifications. If you are exporting to the US, be aware of how gummy format affects certain potency claims and testing methods.
Tablets
What they are: Compressed powder formulations, typically produced by high-speed tablet presses. Can be scored, film-coated, or enteric-coated.
Best for:
- High-volume, cost-sensitive products
- Ingredients that require precise dosing and high tablet hardness (stability)
- Multi-layer tablets (e.g., time-release or color-separated layers)
Key OEM considerations:
- Excipient load. Tablets typically require the highest proportion of inactive ingredients (binders, lubricants, disintegrants) among all formats. This affects label claims for clean products.
- Coating options. Film coating improves swallowability, masks taste, and can add branding color. Enteric coating protects acid-sensitive ingredients from stomach acid.
- Tooling costs. Custom tablet shapes and embossing require new tooling (dies and punches), adding upfront costs but creating brand identity.

How to Make the Final Call
Ask yourself these three questions:
1. What is my target consumer?
Kids or seniors → Gummies or soft capsules
Fitness/health-conscious adults → Hard capsules or tablets
Premium/beauty market → Gummies or premium softgels
2. What are my active ingredients?
Oil-soluble → Softgels
Heat/volume-sensitive probiotics → Hard capsules (cold-filled) or tablets
High-dose botanical blends → Hard capsules or tablets
3. What is my market positioning?
Budget/commodity → Tablets
Natural/organic/vegan → HPMC capsules or pectin gummies
Premium/high-concentration → Softgels or dual-chamber capsules
