What Are Oral Dissolvable Strips?

The base of most quality strips is pullulan, a polysaccharide made by fermenting food-grade starch with the microorganism Aureobasidium pullulans. In the EU it is an authorised food additive, E 1204, and EFSA’s 2025 re-evaluation found no safety concern for its current uses (European Commission, 2008; EFSA, 2025). When it is cast into a sheet and dried, pullulan forms a film that is flexible, almost transparent and dissolves quickly in saliva.

Into that film go the active ingredients, measured per strip, plus small amounts of flavouring and the components that keep the film supple. A strip holds a dose in milligrams and sometimes in micrograms. Pharmaceutical reviews describe oral films as small and lightweight, up to 500 mg for the whole film (Ferlak et al., 2023), and note that they are not generally suitable for treatments that need high doses (Scarpa et al., 2017). This single physical fact shapes everything that follows: which ingredients belong in a strip, and which do not.

Each Smart Strips oral dissolvable strip sits in its own sealed sachet. Pullulan films react to moisture, and an individual sachet protects every dose until the moment you open it. The sachet is light and compact and goes anywhere with you: a pocket, a bag, a gym bag. A box holds 30 strips.

The strip softens the moment it touches the tongue and dissolves within 7 to 30 seconds. In a published laboratory test, pullulan-based oral films disintegrated in under 25 seconds (Gupta et al., 2023).

Strips are a delivery format. They change how a dose is taken and, for part of that dose, how it is absorbed. They do not change what an ingredient is.

What the format does well: - delivers small, precise doses of ingredients that work at milligram levels, such as melatonin, caffeine, L-theanine or vitamin D3; - removes the need for water, a glass or a meal; - gives a single pre-measured dose in a sealed sachet, so you do not count, split or guess; - suits moments when swallowing a capsule is impractical: in a car, on a plane, at a desk between meetings.

What it cannot do: - carry gram-level doses. If you need 400 mg of magnesium or 1,000 mg of vitamin C, a tablet or a powder is the honest answer; - act as a medicine. Supplement strips are food supplements. They do not diagnose, treat or prevent any condition; - make an ingredient work faster in every case. Speed of uptake differs from compound to compound, and research has shown that for some ingredients a mouth-based route does not raise blood levels any faster than drinking them (McCarthy et al., 2025).

We cover the trade-offs between formats in detail in Oral Strips vs Pills, Capsules and Gummies.

Mostly for people with full days and no wish to organise them around pills.

The person who keeps a sleep formula on the bedside table and does not want to get up for water at 11 at night. The commuter who takes a focus strip at a red light. The traveller who goes through airport security with a few sachets in a carry-on and nothing to declare. The person who trains before work and wants a pre-workout formula in a jacket pocket instead of a shaker in the gym bag.

There is also a quieter group: adults who find tablets and capsules hard to swallow. A systematic review puts the figure at about 14% of older adults living at home (Mc Gillicuddy et al., 2016). For them, a strip that dissolves on the tongue removes a small daily discomfort.

Consult your doctor if you are pregnant, nursing, taking medication or have a medical condition.

The category is young, and quality varies. Four checks will tell you most of what you need.

The label states mg per strip. Every active ingredient should be listed with its amount per strip, and vitamins and minerals with their %NRV (nutrient reference value). A list of ingredient names without amounts tells you nothing about the dose.

The dose makes sense for the ingredient. Melatonin at 1 mg or vitamin D3 at 35 µg is a meaningful strip dose. A strip that promises a full gram of anything does not add up.

Where and how it is made. Look for production in a registered facility that follows cGMP (current Good Manufacturing Practice). Smart Strips are made in the USA, in an FDA registered, cGMP certified facility. More on our Manufacturing page.

Individual sachets. A loose strip in a shared container is exposed to air and humidity every time the lid opens. A sealed sachet per strip protects the dose and makes it portable.

Two more details worth reading on the label: allergens (marine collagen, for example, comes from fish) and sugar. Smart Strips are sugar-free and gluten-free, sweetened with stevia. Our full ingredient list is on Our Ingredients.

Many people first met oral films as breath-freshening strips: thin mint films that melt on the tongue and show, in a few seconds, that a film can disappear in the mouth.

Medicine took the format further. In July 2009 the US FDA approved a fentanyl buccal soluble film for pain (BioDelivery Sciences, 2009). In March 2010 an ondansetron orodispersible film for nausea was approved in 16 European countries (Manufacturing Chemist, 2010), and an ondansetron oral soluble film followed in the US in July 2010 (Drugs.com). Since then, oral films have been part of licensed medicine on both sides of the Atlantic, and the pharmaceutical literature on them is where most of what we know about absorption through the mouth comes from (Patel et al., 2011; Hua, 2019).

Supplements are the third chapter. The same technology now carries vitamins, amino acids and botanical extracts at doses suited to a film. Smart Strips approaches this chapter with QuickRelease™ (patent-pending), its own film technology, and with a view that the format deserves as much attention as the ingredients inside it.

Each formula is built for a specific moment of the day, with doses chosen to fit a strip.
