When you approach a contract manufacturer like Dongying Zuoning Biotechnology Co., Ltd. with your supplement concept, one of the first — and most consequential — decisions you’ll face is choosing the right dosage form. Your choice affects not only the supplement’s bioavailability and shelf life but also your minimum order quantities, packaging requirements, production costs, and how your end consumers perceive your brand.
This guide breaks down the four most common dosage forms in the supplement industry: hard capsules, softgels, gummies, and tablets. By the end, you’ll have a clear framework for making the right call for your product line.
Hard Capsules (Two-Piece)
Best for: Powder-based ingredients, herbals, probiotics, and formulations requiring fast release.
Hard capsules consist of two shells — usually made from gelatin or plant-based HPMC (hydroxypropyl methylcellulose) — that are filled with powder, granules, or pellets. They are among the most versatile and cost-effective dosage forms for OEM production.
Advantages:
- Fast dissolution in the stomach (typically 15–30 minutes)
- Easy to swallow with a neutral taste and smell
- HPMC capsules are suitable for vegetarian/vegan products
- Flexible fill weight and size options
- Relatively low tooling costs compared to tablets
Considerations:
- Not ideal for moisture-sensitive or oxygen-sensitive ingredients unless you invest in specialized blister or bottle packaging
- Limited for liquid or oil-based formulations
- Fill uniformity can be a challenge for very low-dose active ingredients
Softgels
Best for: Oil-based ingredients, fat-soluble vitamins, Omega-3, CoQ10, and formulas requiring excellent bioavailability and oxidation protection.
Softgels are one-piece sealed capsules with a gelatin shell surrounding a liquid or oil fill. The manufacturing process — which involves a rotary die machine — is more specialized and expensive than capsules or tablets, but the end product offers distinct advantages.
Advantages:
- Superior oxygen and moisture barrier — ideal for fragile actives like fish oil
- Excellent bioavailability due to the liquid fill format
- Tamper-evident and visually appealing (can be produced in various shapes and colors)
- Masking of unpleasant tastes and odors
Considerations:
- Higher tooling and production costs (typically higher MOQs)
- Limited to liquid or semi-solid fills
- Gelatin-based only (no standard vegetarian softgel option, though some marine or plant alternatives exist)
- Warm climates can cause softgels to stick together if not properly packaged
Gummies (Chewable Supplements)
Best for: Consumer compliance, children’s supplements, joint health, beauty-from-within, and daily multivitamins.
Gummies have experienced explosive growth in the global supplement market, driven by consumer preference for a pleasant, candy-like experience. Modern gummy manufacturing uses starch-based or pectin-based molds, producing sugar-free, organic, and vegan options.
Advantages:
- High consumer acceptance — easier to build a daily habit
- Excellent for targeted demographics (children, seniors, people who dislike swallowing pills)
- Wide format variety: bears, worms, fruits, ovals
- Growing demand in e-commerce channels
Considerations:
- Lower dosage precision compared to capsules or tablets
- Moisture sensitivity — requires desiccant packaging
- Higher per-unit cost than tablets or capsules for equivalent formulations
- Strict temperature and humidity control required in storage and shipping
- Regulatory limits on certain ingredients (e.g., melatonin maximum levels vary by market)
Tablets
Best for: High-dose, stable ingredients; cost-sensitive formulations; products requiring enteric coating or sustained release.
Tablets are produced by compressing powdered ingredients into a solid form using high-pressure punch-and-die machines. They are the most widely manufactured dosage form globally and offer the greatest flexibility in terms of shape, size, coating, and release characteristics.
Advantages:
- Highest dosage precision and uniformity
- Ability to incorporate multiple layers (core, coating, delayed release)
- Options for scoring (splitting tablets in half), coating (for taste masking or enteric release), and imprinting
- Often the lowest cost per serving for stable, high-dose ingredients
- Long shelf life with minimal special packaging requirements
Considerations:
- Longer disintegration time compared to capsules (typically 30–60 minutes)
- Some ingredients may not compress well without excipients
- Taste masking can be challenging
- Not suitable for consumers who have difficulty swallowing pills
