Choosing a format before choosing a formula
Format is a constraint set: dose capacity, sensory tolerance, stability envelope and cost ceiling move together.

Format decisions are often made for brand reasons — a gummy because the category is growing, a stick pack because it travels well, a serum because it presents better on a shelf. Those are legitimate commercial inputs. They are also technical commitments.
Four variables that move together
Dose capacity. A gummy carries a small solid load before texture and sweetness collapse. A capsule is bounded by fill volume. A powder can carry a large dose but exposes taste.
Sensory tolerance. Bitterness, astringency and odour are easier to mask in some formats than others, and masking has a cost in both formulation complexity and ingredient spend.
Stability envelope. Water activity, oxygen exposure and packaging headspace differ sharply between formats and change what preservation or protection the formula needs.
Cost. Format determines the process, the equipment, the packaging and the unit economics far more than the active does in many categories.
A practical sequence
Define the objective and the dose the objective implies. Then list the formats that can physically carry that dose within an acceptable sensory and cost envelope. Only then choose a formula route.
When the desired format cannot carry the intended dose, the project has a genuine decision to make early — split the dose, change the format, or revise the objective. Discovering that at prototype stage is more expensive than discovering it on paper.
