Supplement Formats: Choosing the Right Delivery Form

Capsules, tablets, powders, gummies, softgels, or liquids: how each format performs, what it costs, and how it shapes your entire launch.

Updated Sep 22, 2026

Short answer

Capsules and tablets are the cheapest formats to manufacture and have the widest manufacturer pool; powders suit large gram-sized servings; gummies and softgels need specialized lines, so they carry higher minimums and per-unit costs. The same formula can quote 2x to 3x apart depending on the format. A size 00 capsule holds roughly 630 to 950 mg depending on powder density, which is why most single-capsule servings use it.

Format is your first major product decision, and it constrains every choice that follows: which manufacturers can quote, your order minimums, your per-unit costs, and even which claims fit on your label. Here is the clear trade-off map.

Capsules

Best for: most formulas, fastest to market

As the baseline standard for supplement manufacturing, vegetarian (HPMC) and gelatin capsules offer versatile, taste-neutral, and precise dosing. Broad manufacturer compatibility ensures competitive pricing and accessible minimum order quantities. Formulators should note volumetric limits: standard size 00 shells accommodate approximately 500 to 1,000 mg based on ingredient density, requiring multi-capsule serving sizes for high-dose formulations.

Tablets

Best for: high doses, low cost at volume

Through high-pressure compression, tablets achieve maximum active payload capacity per unit, delivering unmatched cost efficiencies at scale. They support custom shapes, break scores, and specialized protective coatings to enhance swallowability and taste-masking. Key considerations include bulk ingredient compressibility and a clinical aesthetic that may not fit every brand image.

Powders

Best for: large serving sizes — proteins, greens, pre-workouts

For high-mass formulations where dosing is measured in grams, powders offer the most effective delivery matrix. Product success relies heavily on flavor chemistry and blend solubility, alongside specialized packaging options like tub containers or single-serve stick packs.

Gummies

Best for: consumer appeal, kids’ and lifestyle brands

Gummies offer unmatched consumer demand alongside complex production requirements. Operating on limited specialized lines, this format carries higher minimum order quantities and elevated per-unit costs. Active ingredients must withstand heat processing and volumetric constraints, while sugar profiles require careful label consideration. Establishing a pectin (plant-based) versus gelatin formulation base is the foundational starting point.

Softgels

Best for: oils and fat-soluble ingredients

Softgels provide superior stability and precise volumetric dosing for lipid formulations, including Omega-3s, oil-soluble vitamins, and botanical extracts. The one-piece shell protects liquid ingredients from oxidation, though specialized production equipment restricts facility capacity and drives higher order minimums across supplier bids.

Liquids & drops

Best for: tinctures, fast absorption, flexible dosing

Liquid formats provide direct dosing versatility and superior consumer accessibility, balanced against increased freight mass and reduced shelf stability. Formulations require robust preservation matrixes and extensive analytical stability testing to maintain product integrity over time.

How much does each capsule size hold?

Volumetric capacity across the eight standard capsule sizes is determined by powder bulk density. Because shell dimensions dictate fixed internal volumes, active mass per capsule varies according to the specific gravity (g/mL) of the blended powder.

All eight sizes at true relative length. The darker half is the cap that slides over the body. Lengths are the consensus across six published sources; individual suppliers vary by a few tenths of a millimetre.

Size	Volume varies by supplier	Locked length	Typical fill light to dense powder
000	1.37 mL	~26.1 mm	960 – 1370 mg
00	0.90 – 0.95 mL	~23.4 mm	630 – 950 mg
0	0.68 mL	~21.6 mm	475 – 680 mg
1	0.48 – 0.50 mL	~19.4 mm	335 – 500 mg
2	0.36 – 0.37 mL	~17.8 mm	250 – 370 mg
3	0.27 – 0.30 mL	~15.8 mm	190 – 300 mg
4	0.20 – 0.21 mL	~14.3 mm	140 – 210 mg
5	0.13 mL	~11.1 mm	90 – 130 mg

Where these numbers come from. Official pharmacopeial standards govern functional performance criteria such as dissolution rate and content uniformity, rather than geometric shell measurements. Because capsule sizing reflects legacy industry conventions, volumetric capacities vary slightly between suppliers (for instance, 0.90 mL versus 0.95 mL for size 00). Formula design and label claims should always be validated against the technical specification sheet provided by your facility’s primary capsule vendor.

Two different things are varying here, and both matter. Volume varies by supplier — capsule sizes are a naming convention, not a standard, which is why the volume column is a range. Fill weight varies by your powder — fill is volume × bulk density, and a light herbal blend against a dense mineral can differ by more than double in the same shell. The fill column spans roughly 0.70 to 1.00 g/mL, which covers most supplement blends. Your manufacturer will confirm the real number once they have your formula, and that is the number to build the label around.

00 is the default for a reason — it fits most single-capsule servings and every manufacturer stocks it.

0 if swallowability matters to your customer more than capsule count. Noticeably smaller, still holds a useful dose.

000 only if you are certain — it is a large capsule and some customers will not take it twice.

1 and below for potent, low-dose actives, or where you want a small capsule as a deliberate product feature.

When active ingredient mass exceeds single-capsule volumetric limits, formulations can be resolved by scaling shell dimensions, dividing the payload across a multi-capsule serving, or transitioning to tableting compression. Requesting parallel manufacturing quotes across both delivery formats ensures optimal unit economics.

Are capsules more expensive than tablets?

Tablets usually cost slightly less per unit because high-speed compression and low-cost excipients keep manufacturing fast. Capsules cost more for the shell (vegetarian shells run higher than gelatin) and slower filling, but deliver better taste-masking and easier swallowing. The price gap closes at high volumes, and difficult-to-compress powders can make capsules cheaper. Quote both formats to let exact line items guide your choice.

How format changes your quote

The same formula can quote 2x to 3x apart depending on the format you choose. Capsules and tablets offer the largest manufacturer network and most competitive pricing, while gummies and softgels narrow your facility options and raise order minimums. Powders balance between the two, with flavor development as the main wildcard. Getting parallel quotes lets actual supplier pricing reveal the true cost difference, while automatically setting your downstream packaging needs from powder tubs to liquid droppers.
