Thirteen dosage forms, and how to pick the right one
Tablets, capsules, sachets, effervescents, liquids and jars — what each format does well, what it costs you, and the questions that actually decide the choice.
Dosage form is usually treated as a late decision — something to settle once the formula is fixed. It is closer to the opposite. The format constrains the dose you can deliver, the ingredients you can use, the shelf life you can claim, the price you can hit and the market you can sell into.
Here are the thirteen formats we run, grouped by what they are actually good at, and the questions that decide between them.
For the avoidance of doubt, the thirteen are: tablets (plain and coated count as one), bi-layer tablets, effervescent tablets, hard-gelatin capsules, powder sachets, effervescent powder sachets, powder jars, powder bags, liquid sachets, semi-solid sachets, drops and syrups (one line), semi-solid jars, and liquid bottles.
Solids: tablets and capsules
Tablets (plain and coated) are the workhorse. Highest dose per unit, lowest cost per unit at volume, best shelf stability, smallest shipping footprint. Coating adds taste masking, swallowability and a moisture barrier.
The trade-off is formulation difficulty. A tablet has to compress, hold together, and then disintegrate on schedule. Not every ingredient cooperates. Tablets also carry the weakest perception of "premium" in most consumer markets.
Bi-layer tablets press two separate layers into one tablet. That buys you two things: physical separation of ingredients that should not sit in contact, and differential release — one layer dissolving quickly, the other more slowly. Useful for day/night combinations or for an active plus its cofactor.
Hard-gelatin capsules are the default when a tablet is the wrong answer. Easier on difficult ingredients because the powder does not have to compress, better at masking taste and smell, faster to formulate, and widely read by consumers as the more "pharmaceutical" format. They cost more per unit than tablets and hold less.
Rule of thumb: if the formula compresses well and volume is high, tablet. If the ingredient is awkward, hygroscopic, foul-tasting or you need speed to market, capsule.
Effervescents: the newest line
Effervescent tablets and effervescent powder sachets both dissolve in water before drinking. This is our most recent production capability and it solves a specific set of problems.
Effervescents handle doses too large to swallow comfortably — vitamin C at gram level, magnesium, collagen. They convert a supplement into a drink, which changes the compliance picture: people who will not take three capsules will drink one glass. And they carry a strong premium perception at retail.
They are also demanding to make. Effervescent formulations are highly moisture-sensitive, requiring low-humidity production areas, dry granulation and moisture-barrier packaging. The tablet and the sachet are genuinely different production routes, not one process with two outputs.
Choose the tablet for tube packs, portability and a familiar consumer ritual. Choose the powder sachet when the dose is large, when you want flavour and texture latitude, or when a single-serve format suits the channel better.
Powders: sachets, jars, bags
Three formats, three completely different commercial propositions.
Powder sachets are single-dose. They fix the dose, travel well, sample cheaply and suit anything taken once daily. Cost per gram is highest of the three because you are paying for a pack every serving.
Powder jars are bulk, multi-serve, with a scoop. This is the sports nutrition default — protein, creatine, pre-workout. Lowest cost per gram, strongest shelf presence, and dose accuracy is handed to the consumer.
Powder bags (stand-up pouches) sit between the two. Cheaper and lighter than a jar for the same fill, increasingly preferred on sustainability grounds, less rigid on shelf. Common for refills and for larger fills where jar shipping costs bite.
The question that decides it is not really the powder. It is the channel. Pharmacy and clinic distribution leans sachet. Gym and e-commerce leans jar or bag.
Liquids: sachets, drops, syrups, bottles
Liquid sachets are single-serve drinkable shots. Fast perceived onset, no swallowing required, easy to flavour, and they carry a premium. Short shelf life relative to solids and heavier to ship.
Drops and syrups are the paediatric and geriatric answer, and the answer whenever dose has to be adjustable. A syrup lets a parent give 2.5 ml instead of 5 ml — a tablet cannot do that. Drops concentrate the dose into a small volume for vitamin D, vitamin K2 and similar.
Liquid bottles are ready-to-drink, multi-serve or single-serve depending on fill. The most convenient format for the consumer and the most expensive to ship, since you are paying freight on water.
A note on experience: liquids were where this factory began. Our first production lines were liquid, and the syrup capacity has gone from a single line in 2020 to six.
Semi-solids: sachets and jars
Semi-solid sachets hold gels and pastes — honey-based products, nut-based blends, gel energy formats. Single-dose, no water needed, and they handle ingredients that neither powder nor liquid formats manage well.
Semi-solid jars are the multi-serve version: creams, pastes, spreads, honey blends.
This category is where some of the more interesting product work happens, because it is the least crowded shelf. Honey with hazelnut, coffee, mint, green apple or cinnamon extract is a semi-solid product. So is an extra-virgin olive oil infused with chilli, thyme or garlic.
The four questions that actually decide it
Strip away the formats and the decision comes down to four things.
1. How much active do you need per dose? Above roughly a gram, swallowed solids become unpleasant. That pushes you toward powders, effervescents or liquids.
2. Who takes it, and how? A child cannot swallow a tablet. An elderly consumer may struggle with a large capsule. An athlete already owns a shaker. A busy professional wants something in a pocket.
3. Where does it sell? Pharmacy, gym, clinic, e-commerce and export each have format conventions. Fighting them costs marketing money you could have saved by choosing differently.
4. What does the ingredient allow? This is the one brand owners skip and manufacturers raise first. Hygroscopic, oily, foul-tasting, heat-sensitive and waxy materials each rule out formats. Some materials are difficult enough that factories decline them. Find out in week one, not month three.
And one more
Think about your second product before you finalise your first.
A manufacturer running four dosage forms will quote your tablet confidently and then be unable to make your liquid sachet eighteen months later — at which point you are either managing two suppliers or re-qualifying from scratch. Range is not a vanity metric. It is how you avoid repeating this entire process.
