Liquid Supplement Drops Explained Simply: Label Basics Guide

What sublingual means

The word sublingual looks technical, but it is simply Latin put together: sub means under and lingua means tongue. A sublingual product is one that is held under the tongue for a short time before swallowing. You may have seen the word on product pages for lozenges, strips and liquid drops, and it is a handy label term to recognize.

Thermo Ignite is a dietary supplement in sublingual liquid drop form. The brand's directions read that you place 1 mL under the tongue each morning before breakfast, hold it there for 20 to 30 seconds before swallowing, and follow it with an 8 oz glass of water. The brand describes the drops as fast-absorbing, made without gelatin capsules, vegetarian, vegan-suitable and non-GMO. Our page on what Thermo Ignite is gives a clear overview, and this guide shares the vocabulary behind the format.

Why a liquid format at all

Liquids appeal to many shoppers for simple, practical reasons. There are no capsules or tablets to swallow, a liquid can be measured in small steps, and a bottle with a dropper is easy to keep on a shelf or in a kitchen cabinet. For people who have trouble with pills, or who just prefer a different style, drops offer another route to a daily routine.

• No capsule shell: a liquid can be offered without gelatin capsules.
• Adjustable measuring: a dropper or pipette marked in mL allows precise portions.
• Flavor options: liquids may be flavored or unflavored, depending on the brand.
• Compact packaging: a 2 fl oz (60 mL) amber glass bottle fits easily in a cabinet or a travel bag.

Serving size in mL: reading the number

The abbreviation mL stands for milliliter, one thousandth of a liter. It is the common metric unit for small liquid amounts, and it appears on measuring spoons, syringes and the pipettes inside dropper bottles. For comparison, a standard teaspoon is about 5 mL, so 1 mL is a small, precise amount. The bottle's size is given in both US and metric units: 2 fl oz and 60 mL describe the same volume.

On a Supplement Facts panel, the serving size for a liquid is normally written in mL or fl oz, and the directions use the same unit. If you are not sure how to find your serving size, our post on how to read a liquid supplement label shows where to look. The NIH Office of Dietary Supplements consumer guide is another friendly walk-through.

How to measure with a dropper

Dropper measuring takes a minute to learn and then becomes second nature. A well-made dropper has a rubber bulb on top and a glass pipette below it, sometimes with printed marks along the tube. Our guide to amber glass dropper bottles explains each part in more detail.

• Hold the bottle upright and unscrew the dropper assembly.
• Squeeze the bulb gently, place the tip into the liquid and release the bulb slowly.
• Watch the liquid rise in the pipette and stop at the mark your directions call for.
• Lift the dropper out, keep the tip pointed down and move it to the spot where you will use the liquid.
• Squeeze the bulb to release the liquid, then rinse or wipe the tip and close the bottle firmly.

Measure at eye level with the pipette held steady, and place a paper towel under your hand the first few times. If your dropper has no marks, follow the measuring instructions printed on the label exactly as written.

Common dropper habits worth building

Good habits make measuring effortless. Wash your hands before you start, keep the tip from touching your mouth or any surface, and return the dropper to the bottle after each use. Wipe the neck of the bottle if any liquid collects there so the cap does not stick. Store the bottle upright with the cap tightened, and keep the area around it dry. These small steps keep the routine tidy and the bottle looking neat from the first morning to the last.

Glycerin, water and other bases in general

Liquid products need a base, called a carrier or vehicle in manufacturing language, that holds the other ingredients. Two of the most common are water and vegetable glycerin. Glycerin is a clear, thick, mildly sweet-tasting liquid that is made from plant oils, and it is widely used in foods and personal care products. Other possible carriers include certain alcohols or plant oils, depending on the product. The label's "Other Ingredients" line is where you find which base a particular product uses.

Here is a small glossary that makes liquid labels easier to read:

• Supplement Facts: the panel that lists the serving size and named ingredients.
• Other ingredients: items that are not the headline ingredients, such as carriers and flavors.
• Extract: a concentrated form drawn from a plant part.
• Serving size: the amount the label calls one serving, such as a specific number of mL.
• Directions: the manufacturer's instructions for when and how to take the product.

Making a drops routine easy

Consistency is the secret of any daily routine, and liquids make it easy to attach the step to something you already do.

A morning routine works best when each step is small. Set the bottle where you will see it, perhaps next to the glass you fill with water. For general ideas on building that kind of routine, see our post on a calm morning routine before breakfast, and the CDC water and healthier drinks page for general hydration information. If you are curious about the general category, the U.S. FDA dietary supplements page covers it in plain language.
