Capsules vs Tablets: When to Choose Each in Food Supplement Manufacturing
Choosing between capsules and tablets is one of the first and most important decisions in food supplement development. While both dosage forms are widely used and accepted by consumers, they serve different manufacturing, formulation and scalability purposes. From a contract manufacturing organization (CMO) perspective, the choice is rarely about preference and more about technical feasibility, cost structure and long-term production strategy.
This article explains when capsules are typically used and when tablets are the better option, focusing on real manufacturing logic rather than consumer marketing claims.

Capsules and tablets solve different manufacturing problems
Capsules and tablets are often presented as interchangeable dosage forms. In practice, they address very different formulation challenges.
Capsules act primarily as a container. They allow powders, granules or blends to be filled with minimal mechanical stress. Tablets, by contrast, are a compressed structure, where ingredients must tolerate pressure and form a stable, self-supporting unit.
For CMOs, this distinction defines the entire development pathway. Capsules often allow faster market entry, while tablets require more upfront work but offer better scalability and cost efficiency over time.

When capsules are typically chosen
Capsules are frequently selected at early stages of product development or when formulation behavior limits compression options. They are particularly useful for ingredients that do not compress well or that degrade under mechanical stress.
From a manufacturing perspective, capsules are often used when the formulation contains:
From a manufacturing perspective, capsules are often used when the formulation contains:
Amino acids
with poor compressibility
Botanical extracts
with variable particle structure
Hygroscopic
or brittle ingredients
Blends
that are difficult to granulate
Capsules allow these materials to be filled without altering their physical structure. This reduces development time and avoids complex formulation optimization.
Encapsulation services at BF-ESSE
BF-ESSE offers contract and white-label encapsulation services for food supplements, supporting a wide range of powder and blend formulations. Encapsulation is suitable for ingredients with limited compressibility or sensitive physical properties and is often used for flexible batch sizes and faster market entry. Each project is evaluated for formulation behavior, capsule type and packaging compatibility to ensure stable and repeatable production.

Tablet Pressing Services at BF-ESSE
BF-ESSE provides tablet pressing services for food supplement manufacturing, focusing on scalable production and long-term cost efficiency. Tablet projects are assessed for compression feasibility, tablet format selection and packaging requirements. Tablet pressing is commonly used for vitamins, minerals and complex formulations where high-volume, repeatable manufacturing is required.

Capsules - fast route to market
One of the main reasons CMOs recommend capsules is speed. Capsule filling generally requires fewer development steps compared to tablet compression.
This makes capsules suitable for:
This makes capsules suitable for:
Pilot launches
Test-market products
Limited production volumes
Brands validating demand before scaling
For contract manufacturers, capsules provide flexibility and reduce early technical risk, especially when formulation data is limited.
Limitations of capsules in long-term production
Despite their flexibility, capsules have inherent limitations. Capsule shells add dependency on external raw materials and introduce additional variables such as shell compatibility, moisture sensitivity and storage conditions.
- At higher volumes, capsules often become less cost-efficient due to:
- Capsule shell costs
- Lower fill density per unit
- Larger packaging volume
- Reduced logistics efficiency
- As production scales, these factors become increasingly relevan
When tablets are typically chosen
Tablets are usually selected when scale, cost efficiency and dose density become priorities. Unlike capsules, tablets allow a higher amount of material to be delivered in a compact form without relying on an external shell.
- Tablets are often recommended when:
- Target volumes are high
- Long-term production is planned
- Cost per dose must be optimized
- Supply chain efficiency matters
- Vitamins, minerals and multivitamin formulations are typical examples where tablets outperform capsules over the product lifecycle.
Tablets and formulation commitment
Choosing tablets implies a stronger commitment to formulation optimization. Active ingredients rarely compress well on their own, which means excipients and compression parameters must be carefully balanced.
This upfront effort is the reason tablets are less common in early-stage launches. However, once optimized, tablets offer high repeatability and stability, which is critical for contract manufacturing at scale.

Stability and shelf-life considerations
Stability is another key differentiator.
Tablets generally offer:
Tablets generally offer:
- Better resistance to mechanical stress
- Lower sensitivity to shell-related moisture issues
- Improved stability in bulk packaging
Packaging implications for capsules and tablets
Packaging interacts differently with each dosage form. Capsules are more sensitive to abrasion and deformation, especially in jars and bottles. Tablets, when properly formulated, tend to tolerate handling and transport more robustly.
This makes tablets more suitable for:
This makes tablets more suitable for:
- High-speed packaging
- Large-count containers
- Long distribution chains
Cost dynamics over the product lifecycle
In early production phases, capsules often appear more economical due to lower development costs. Over time, however, tablets usually become the more cost-effective option.
For CMOs and brand owners, the cost curve typically looks like this:

Capsules are typically chosen when formulation flexibility and speed are the priority, especially for complex or compression-sensitive ingredients. Tablets are preferred when scale, cost efficiency and logistical performance are critical.
Neither dosage form is inherently better. The right choice depends on where the product is in its lifecycle and how it is expected to grow.

FAQ: Capsules vs Tablets in Food Supplement Manufacturing
Capsules are generally easier to launch because they require less formulation optimization and do not involve compression forces. However, this does not mean they are simpler over the full product lifecycle. At higher volumes, capsule production can introduce additional complexity related to shell supply, moisture control and packaging efficiency.
Tablets allow higher dose density per unit and do not rely on an external shell. This makes them more cost-efficient at scale, easier to package in large counts and more suitable for long-term, high-volume production.
In many cases, no. Formulations that work well in capsules may not compress effectively into tablets without modification. Tablet production typically requires additional excipients and process optimization to achieve mechanical stability and consistent quality.
Tablets generally offer better mechanical stability during transport and packaging. Capsules can be more sensitive to environmental conditions, particularly moisture, depending on the shell type and fill material. Stability must be evaluated in relation to formulation and packaging.
