The dosage form decides more of a supplement’s cost, shelf life and customer experience than any single ingredient choice. Brands often pick a form because it is fashionable, then discover mid-project that their active ingredient will not fit the dose into a gummy, or will not survive a drink’s water activity.
This guide compares the seven forms a Japan-made supplement commonly takes, sets out how much active ingredient each one can realistically carry, and flags the one regulatory change that now applies differently across them.

What each dosage form is built for
Tablets and hard capsules carry the highest dose per unit at the lowest cost; softgels, gummies and jellies carry less but taste and feel better; powders and drinks carry the most but ask the most of the consumer.
| Dosage form | What it is | Typical dose capacity | Cost driver |
|---|---|---|---|
| Tablet | Compressed powder, plain or coated | High (up to ~1 g per tablet before swallowing becomes difficult) | Compression tooling, coating |
| Hard capsule | Two-piece shell filled with powder, granule or pellets | Moderate–high (shell size limits fill weight) | Capsule shell, filling speed |
| Softgel | Sealed gelatin or plant-based shell around a liquid or oil fill | Moderate (fill volume, not weight) | Encapsulation equipment, fill oil |
| Powder / granule | Loose or granulated powder, scooped or in a sachet | Very high (gram-level doses possible) | Blending, drying, packaging format |
| Jelly | Set gel eaten with a spoon or squeezed from a pouch | Moderate | Gelling agent, retort or aseptic filling |
| Drink | Liquid in a bottle or pouch | High volume, but active content is diluted | Bottling line, pasteurisation, sugar/preservative system |
| Gummy | Chewed, gelled confectionery | Low–moderate (gelling agent and sugar take up space) | Depositing equipment, active-ingredient loss during cooking |
Stability and how forgiving each form is
Dry, sealed forms (tablet, hard capsule, powder) protect an unstable ingredient best; forms with water activity (gummy, jelly, drink) are the most demanding on that same ingredient.
Moisture, oxygen and heat degrade many actives — vitamin C, certain probiotics, some botanical extracts. A dry compressed tablet or a powder in a sealed sachet gives the formulator the most control over all three. A gummy or jelly holds water by design, so a heat-sensitive vitamin can lose a meaningful share of its potency during cooking and setting, and the finished product keeps losing potency in a hot, humid climate unless the packaging is chosen to compensate. A drink dilutes the active in water from the start and usually needs a preservative system or aseptic processing to stay stable without refrigeration.
This is why a specification should name the dosage form and the target shelf life together, not one after the other: the second decision constrains the first.
Taste, texture and who is taking the product
Hard capsules and coated tablets hide taste best; gummies, jellies and drinks put taste and texture at the centre of the product.
A capsule shell or a film coating masks almost any raw material, which is why bitter or fishy actives (many botanical extracts, fish oil, some amino acids) are usually capsuled rather than put in a chewable form. A gummy, jelly or drink cannot hide the active the same way — sourness, bitterness or a chalky mouthfeel from a mineral has to be masked with flavour, sweetener and acid balance, which adds formulation cost and time. Chewable and confectionery-style forms also suit people who dislike swallowing tablets, including some older adults and children, which is a legitimate reason to choose them — provided the packaging and labelling address who should and should not take the product. See our chewable and effervescent tablet guide and gummy supplement guide for the detail on each.
Which forms suit which ingredients
An ingredient’s own stability and taste usually decide its dosage form before marketing preference does.
- Collagen peptide is typically dosed in grams, which rules out a small tablet or capsule at a meaningful dose — powder, stick pack, jelly and drink are the common Japanese formats. See the collagen peptide guide and our powder and stick pack guide.
- Astaxanthin is an oil-soluble carotenoid, usually delivered in a softgel so the oil carries it without needing a separate fat matrix. See the astaxanthin guide.
- Lactic acid bacteria need to survive processing heat and, for some strains, gut transit; tablet, hard capsule and certain powder formats protect a moisture- and heat-sensitive strain far better than a gummy or a pasteurised drink. See the lactic acid bacteria guide.
- GABA is water-soluble, stable and dosed in milligrams, so it fits almost any form, which is why it appears across tablets, confectionery and drinks in Japan. See the GABA guide.

The GMP change that now treats dosage forms differently
From 1 September 2026, Japan’s Consumer Affairs Agency (CAA) made GMP legally mandatory for Foods with Function Claims notified as tablets, capsules and similar forms such as powders and liquids; the rules do not spell out whether gummy, jelly and confectionery-style forms fall within that category.
Japan’s two-year transition period for the revised Foods with Function Claims (FFC) rules ended on 31 August 2026. From 1 September 2026, a notified FFC product in “supplement shape” — tablet, capsule, and similar concentrated forms including powder and liquid — must be manufactured under GMP, with the manufacturer subject to CAA on-site inspection. The CAA’s stated reason is that these forms are both easy to over-concentrate and hard to judge by taste or smell if something has gone wrong.
Gummy, jelly and chocolate-style FFC products are not named either way. The GMP obligation applies to products notified in the “tablets, capsules and similar foods made from natural extracts” category; a product notified instead as an “other processed food” must explain why it does not belong in that category and state, for each manufacturing site, whether it follows GMP, HACCP, ISO 22000 or FSSC 22000. A CAA document presented to a food safety council committee on 23 April 2026 noted that the scope of the earlier GMP guidance (tablets, capsules, powders, liquids and similar forms) does not make clear whether gummy-shaped products are covered. The same document set out a proposal for a new supplement regulation under which forms whose taste is easy to notice when eaten, such as gummies, would at first be left out of mandatory GMP while voluntary GMP is encouraged, and it states that the proposal may change. This does not change requirements for products outside the FFC system (Foods with Nutrient Function Claims or ordinary foods).
For a brand planning a Japan-made product, the practical effect is that a tablet, capsule or powder FFC product must be sourced from a GMP-certified line as a legal requirement. For a gummy or jelly FFC product, do not plan on an exemption: agree the notification category with the factory early, and use a GMP-certified line, which keeps the product on safe ground however the category question and the proposed rules are settled.
Before you ask for a quotation
A factory can quote accurately once the ingredient, dose, form and target markets are fixed together.
- The active ingredient(s) and the dose you want per serving
- Whether the ingredient is heat-, moisture- or oxygen-sensitive
- Your preferred dosage form, and why (dose capacity, taste, target consumer)
- Whether the product will be notified as a Food with Function Claims in Japan
- Target shelf life and the climate it will be stored and sold in
- Countries you plan to sell in

Frequently asked questions
1. Which dosage form is cheapest to manufacture?
Tablets are usually the lowest cost per serving for a simple, stable, small-dose ingredient, because compression is a fast, well-established process. Cost drivers change once an ingredient needs a high dose, a coating, or protection from moisture.
2. Can any ingredient go into a gummy?
No. A gummy has to hold a meaningful amount of water, sugar or sugar substitute, and gelling agent, which leaves less room for the active than a tablet or capsule of the same size, and the cooking step can degrade heat-sensitive actives.
3. Does the new GMP rule apply to my product if it is not sold in Japan?
The rule applies to Foods with Function Claims notified and sold in Japan. A Japan-made product for export only is not covered by this specific Japanese notification system, but a GMP-certified line is good practice for any market and is worth asking for regardless.
4. Why do some Japanese supplements come as a drink or jelly instead of a tablet?
Mainly dose size and consumer preference. Ingredients dosed in grams, such as collagen peptide, do not fit a swallowable tablet at an effective dose, and a drink or jelly format also suits people who prefer not to swallow tablets.
5. Is a gummy less safe than a tablet because its GMP status is less clear-cut?
Not necessarily — gummies are still subject to Japan’s general food safety and labelling law, and they can be made on GMP-certified lines. The open question is which legal manufacturing-management requirement applies, not whether gummies are inherently riskier.
