The pill format you pick sets your cost per bottle, how many pills a serving takes, whether you can say vegetarian, and what your reviews will complain about. Here is how the three compare, drawn from FDA, USP and the companies that make capsules and coatings, with each vendor's bias named.
Short answer
Capsules are usually the simplest way to launch a powder formula, hide taste and offer a vegetarian shell. Tablets pack the most into one pill and are often cheaper at large volume, but need more development and can be hard to swallow. Softgels suit fish oil and other oil-based ingredients, but usually carry higher minimums. Pick the format that fits your ingredients, then your price.

FDA size and shape guidance
A hard-shell capsule is a two-piece shell, gelatin or plant-based, filled with powder. A tablet is powder pressed into a solid shape, usually with binders and other helpers called excipients, and often coated. A softgel is a one-piece sealed shell filled with a liquid, usually an oil. Those definitions follow a 2017 SupplySide Supplement Journal breakdown of dosage forms written by an executive at a contract manufacturer.
On Amazon, the choice shows up in four places: the price you can charge per serving, the unit count in your title, how many pills a serving takes, and what customers say in reviews about swallowing, smell and aftertaste. Get the format wrong and no listing copy fixes it. Our gummy launch guide and powder launch guide cover the other two common formats.
Capsule sizes are standardized from 000, the largest, down to 5. Lyfe Group (formerly CapsCanada), which sells HPMC capsules, says sizes 00, 0, 1 and 2 are the most common in supplements, and that most adults can easily swallow a size 0 while children and older adults often struggle with it. How much fits depends on the density of your powder, not just the shell. The LFA capsule size chart, from a company that sells capsules and filling machines, shows a size 00 holding about 540 mg of a light 0.6 g/ml powder and 900 mg of a 1.0 g/ml powder.
Tablets can carry more per pill because compression packs powder tightly, which is why Sourcify, a manufacturing sourcing firm, notes that large doses can sometimes go into one tablet instead of several capsules. The limit is swallowing. The FDA's size, shape and physical attributes guidance is written for generic drugs, not supplements, but it is the clearest federal reference on pill size: it recommends that a tablet's largest dimension not exceed 22 mm and that capsules not exceed a standard 00 size, and cites estimates that up to 40 percent of Americans have some trouble swallowing pills.
Softgels have the tightest limit for powders. The SupplySide breakdown says softgels can carry up to about 50 percent powder suspended in oil and are not suited to high powder doses.
There is no single answer to which format is cheaper, and the sources that say so mostly sell one of them. Sourcify says tablets are often cheaper at scale because presses run very fast and there is no shell to buy, but that capsules can cost the same or less when ingredients compress poorly and need extra binders, flow agents and testing to become a tablet. Colorcon, which sells tablet coatings and excipients, summarizes a paper written for Capsugel, a capsule maker, which found that capsules usually save money up front because they need fewer steps and less equipment, while tablets can win at high volume. That article is written about drug manufacturing, but the cost logic carries over. Both points fit together: capsules are cheaper to start, tablets can be cheaper to scale.
For a sense of starting prices, Build Your Own Brand, a contract manufacturer that lists Hong Kong and Shenzhen locations, lists capsules at $1.50 to $2.50 per unit with a 500-unit minimum, against $2.00 to $3.50 for gummies and $3.00 to $5.00 for powders, and says those prices include manufacturing, testing and standard packaging. It does not list tablets or softgels. On minimums, the SupplySide breakdown says softgel minimum order quantities are typically higher than for tablets or hard capsules, and Sourcify says tablet production favors larger runs. Get quotes in your own formula from more than one manufacturer before you decide.
Hard capsules come in gelatin, HPMC (hypromellose, a plant cellulose) and pullulan (a starch-based polymer). LFA's chart shows vegetarian and gelatin shells in the same standard sizes, so switching does not change your pill count. If you want to say vegetarian or vegan on the label and listing, every part of the product, including the shell and any coating, should support that claim.
The SupplySide breakdown says softgel shells are made from bovine, porcine or fish gelatin, or from non-animal materials such as starch and carrageenan. Fish is one of the nine major food allergens FDA lists, and FDA's allergen labeling rules cover dietary supplements, so a fish gelatin shell or a fish oil fill can trigger an allergen declaration. Confirm the wording with your manufacturer and a regulatory attorney. See FDA's food allergen page in the sources below.
A film coating helps a tablet slide down. The FDA's size guidance notes that the lack of a film coating can reduce how easily a tablet moves when swallowed, and that coatings also affect taste and smell. Enteric (delayed-release) coatings keep a tablet or softgel intact in the stomach; USP's test requires delayed-release tablets to show no disintegration after an hour in simulated stomach fluid.
USP General Chapter 2040, the disintegration and dissolution standard for supplements, requires uncoated and plain coated tablets to fully disintegrate within 30 minutes, and has a separate rupture test for softgels. Ask your manufacturer whether it tests to 2040. NSF lists disintegration testing among the tests its Certified for Sport program can include.
Colorcon says tablets can offer better stability and shelf life for moisture- and heat-sensitive ingredients, and the SupplySide breakdown says softgels protect contents from oxidation but are sensitive to heat and humidity. Whatever you choose, the FDA's labeling guide says an expiration date is optional but, if used, must be supported by valid data.
The Supplement Facts rules are the same for every format, but the wording changes. Under 21 CFR 101.36(b) the serving size uses a term that fits the form, such as tablets or capsules, and the panel heading can read Each Tablet Contains or Amount Per 2 Tablets instead of Amount Per Serving. The shell, coating, binders and fillers all belong in the ingredient list below the panel; the FDA's ingredient labeling guide gives Cod liver oil, gelatin, water, and glycerin as an example list for a softgel. Our Supplement Facts panel guide covers the panel in full.
Two rules depend on format. If a tablet or capsule contains iron, 21 CFR 101.17(e) requires the boxed warning that accidental iron overdose is a leading cause of fatal poisoning in children under 6; the rule names solid oral dosage forms such as tablets and capsules. Separately, the Consumer Product Safety Commission's 16 CFR 1700.14(a)(13) requires child-resistant packaging for supplements with 250 mg or more of elemental iron in a single package. Ask a regulatory attorney how both apply to your product.
Amazon's Dietary supplements policy lists unit count among the attributes a supplement listing must carry. Shoppers compare 60 capsules against 120 tablets, so state servings too. A 120-count bottle at two per serving holds 60 servings, which is a 60-day supply at one serving a day, not 120 days.
As of October 2026, Amazon's policy says sexual enhancement and weight loss supplements cannot be sold in single- or double-pill packs. That rules out blister sample packs in those categories.
Shoppers cannot feel a pill before they buy. A secondary image or infographic that shows the actual capsule or tablet next to a coin or fingertip sets expectations. Keep the main image to the product itself. Our infographic images guide covers how to do that inside Amazon's image rules.
Softgel or tablet, the claim line is the same: structure/function claims with the FDA disclaimer, no disease claims. See our structure/function claims guide.
Write down every active, whether it is a dry powder, an oil or an extract, and the dose per serving. Oils point to softgels. Large dry doses point to tablets or several capsules. Sticky, bitter or smelly botanicals point to capsules.
Ask the manufacturer for your blend's bulk density, then check how many capsules of size 0 or 00 the dose needs. If it is more than two or three per serving, price out a tablet, or consider a powder or gummy.
If a tablet would be close to 22 mm, the FDA's generic drug reference point, ask for a smaller oval shape, a film coating, or a split dose.
Choose gelatin or a plant shell now, because it changes the claim you can make and the ingredient list. For softgels, confirm the shell source and declare fish if it is used.
Ask at least two manufacturers to quote your formula as a capsule and as a tablet, or a softgel if you have oils, at the same quantity. Compare unit cost, minimums, development time and stability data, not just price.
Ask whether the finished product is tested for disintegration to USP 2040 and how the expiration date is supported. Add the answers to the spec you sign.
Put the unit count and servings in the title, show the real pill size, and use bullets to answer swallowing, shell and allergen questions. Our supplement launch guide covers the rest of the launch.
The format decision is mostly yours and your manufacturer's. You do not need an agency to choose between a capsule and a tablet, and you should not pay a marketing firm for formulation advice. A good manufacturer will tell you what your ingredients allow. If you need help judging manufacturers, use our guides on how to vet a supplement manufacturer and questions to ask a supplement manufacturer. We do not recommend or broker manufacturers, run lab tests or give legal advice; iron rules and child-resistant packaging questions go to a regulatory attorney.
Help pays off after the format is set: turning a 60-count bottle into a title, images and bullets that sell in a crowded search, managing Amazon's testing notices, and running the launch. That is Amazon brand management work.
