In short
- The form changes how easy a product is to swallow, store and measure, and how long it lasts.
- Capsules and tablets are convenient and pre-measured; powders and liquids are flexible but need measuring.
- Read "other ingredients": tablets generally need more binders than capsules, and liquids may include sweeteners and preservatives.
- Compare cost per serving, not cost per bottle, across forms.
Open any section of the shop and you will find the same ingredient sold as a capsule, a tablet, a powder, a liquid or a softgel. The nutrient is the same; the experience of using it is not. This guide compares the common forms so that you can choose by what suits your routine, not by what is first on the shelf.
Capsules
A capsule is a shell, usually gelatin or a plant-based material such as hypromellose, filled with powder, granules or a liquid. Capsules are popular because they hide taste and smell, are easy to swallow for most people, and usually need fewer additional ingredients than tablets.
- Good for: ingredients with a strong flavor, herbal powders and extracts, and anyone who wants a simple, pre-measured serving.
- Worth knowing: gelatin is animal-derived, so check the "other ingredients" line if you avoid animal products. Plant-based shells are available in many products.
- Size: some ingredients are bulky, so a "serving" may be three or four capsules even though each capsule seems light.
Tablets and caplets
A tablet is a compressed block of powder. Because the powder has to hold together, tablets generally include binders and sometimes coatings. A caplet is a tablet shaped like a capsule, which many people find easier to swallow. Tablets can pack a high amount of an ingredient into a small space, which is why large-dose minerals such as calcium and magnesium are often sold this way.
- Good for: bulky nutrients, long shelf life and lower cost per serving.
- Worth knowing: some tablets are coated or "enteric-coated" to control where they dissolve. The label usually says so; do not crush a coated tablet unless the directions allow it.
- Size: large tablets can be hard to swallow. Some products are scored or sold as chewable alternatives.
Softgels
A softgel is a soft, sealed capsule filled with oil or a liquid. It is the standard choice for oils and for fat-soluble ingredients such as vitamin D, vitamin E, CoQ10 and krill or fish oil, which dissolve better in oil than in powder. They are easy to swallow, but they can be sensitive to heat and may stick together in warm conditions. For storage tips see Storing supplements.
Powders
Powders are measured out with a scoop or spoon and mixed into water, juice, a smoothie or food. They suit ingredients that are taken in larger quantities, such as fiber, amino acids and creatine, and they let you adjust the amount to suit your own needs and the manufacturer's directions.
- Good for: larger servings, people who dislike swallowing pills, and flexible measuring.
- Worth knowing: use the scoop supplied and level it; scoop sizes differ between products. Flavored powders often contain sweeteners, flavors and colors, so read the full ingredient list.
- Storage: powders absorb moisture from the air. Close the lid and keep the scoop dry.
Liquids, tinctures and drops
Liquid products come as syrups, extracts, tinctures and dropper bottles. They are measured with a dropper, a spoon or a cap, which is a precise method if you read the directions and use the measure provided. Many people find liquids easier than pills.
- Good for: people who cannot or prefer not to swallow pills, and for ingredients that are traditionally taken as an extract.
- Worth knowing: some liquid extracts use alcohol, glycerin or sugar as a base, and some need to be refrigerated after opening. Always check the label for both.
- Taste: expect a strong flavor from herbal liquids. Diluting in water or juice, if the directions allow, is common.
Gummies, chewables and lozenges
These are designed for taste and ease. They tend to contain sugar or sugar alcohols, flavoring and colorants, and they usually carry smaller amounts of active ingredients per piece than a capsule. Check the serving size carefully: with a pleasant-tasting product it is easy to take more than the label says.
How to choose
| If you want... | Consider |
|---|---|
| Simple, pre-measured and easy to carry | Capsules or tablets |
| A fat-soluble ingredient such as an oil | Softgels |
| A large serving or an adjustable amount | Powder |
| To avoid swallowing pills | Liquid, powder or chewable |
| The lowest cost per serving | Compare servings per bottle across forms |
Whatever the form, the label rules are the same: check the serving size, the amount per serving and the "other ingredients". Our guide to reading a supplement label walks through each step.
Three practical tips
- Match the form to your habit. A product you take consistently is better than a better-sounding one that stays in the cupboard.
- Do not change the form without checking the amount. A tablet and a powder of the same ingredient may have different serving sizes and amounts.
- Use the measure supplied. A scoop, dropper or cap is calibrated to the product it comes with.
Browse by form in the shop
The shop does not filter by form, but the product title almost always names it ("capsules", "tablets", "liquid", "softgels", "powder"). Use the search box in the header: try searching for softgels, powder or liquid to see what is available.
