My mom called me last spring with a question that's stayed with me: "Should I throw out my B12 pills and switch to strips?" She'd been swallowing the same drugstore multivitamin for fifteen years and hated every one of them.
I run a dissolvable strip company, so the easy thing would be to say yes, throw out every pill. I'm not going to. The honest answer, which is the one I gave her, is that a strip and a capsule are two ways of getting the same ingredients into the same body — and the format is worth changing when the format is the thing standing in your way. If capsules make you gag, or you never actually take them, that's a real problem and the strip solves it. If you're happily swallowing a capsule every morning, switching mostly buys you a nicer ritual.
This article is the version of that conversation without the marketing. It used to contain a table of absorption percentages. We removed them, because we could not stand behind them, and I've explained what replaced them below.
The short version
Here's the practical summary for readers who want the verdict and will trust the rest of the article to defend it:
- A strip makes sense if: you struggle to swallow pills, you gag on capsules, you hate powders and shaker bottles, you travel and don't want a pill organiser, or you've quietly abandoned three supplements in a row because taking them was a chore.
- A capsule makes sense if: swallowing is no trouble, you need a large dose (most minerals, fibre, amino acids, vitamin C in grams), or you're buying on price alone. Capsules are cheaper to manufacture and it shows on the shelf.
- What the format does not change: for most nutrients, your digestive tract is still doing the absorbing either way. A strip that dissolves in your mouth mostly gets swallowed with your saliva. That's not a flaw — for most ingredients it's exactly where they need to go.
If the question behind your search is "is the strip format real science or marketing," the fair answer is: the format is real and genuinely useful, the absorption story that the category built itself on is mostly overstated, including by us until recently.
The questions I actually ask before adding a nutrient
Before an active goes into the XYNE lineup, it goes through five questions. You can apply the same five to anything you're holding.
1. Does this ingredient need the gut to work? Most do. Probiotics need to reach the intestine. Fibres like polydextrose are fermented in the colon. Collagen peptides are digested and absorbed by intestinal transporters. Mushroom beta-glucans act on immune receptors in the gut lining. Iron uptake is regulated in the duodenum. Vitamins D3 and K2 need bile salts to be absorbed at all. If the gut is the destination, the mouth is not a shortcut — it's just where the product happens to dissolve.
2. Does the dose physically fit on a film? A thin strip can carry a small amount of active. That rules out calcium, magnesium at useful doses, fibre, gram-scale vitamin C, and most amino acid loads. This isn't a debate, it's arithmetic.
3. Will the person actually take it? This is the question the industry treats as soft and I treat as the most important one. A supplement that sits unopened in a cupboard delivers nothing at all. Difficulty swallowing pills is common and under-discussed, and "I hate the taste of the powder" ends more routines than any pharmacological factor.
4. Does it taste tolerable in the mouth? Capsules hide everything. A strip hides nothing, which is a genuine constraint. Bitter botanicals need real flavour work, and some ingredients we've tried simply didn't survive the taste test.
5. Is the price defensible? Film manufacturing costs more than pressing a tablet. If the format doesn't solve a real problem for you, that premium isn't worth paying.
Notice what's missing from that list: any promise that the route makes an ingredient work better. We took that question out, because when we audited our own line against the published literature, it didn't survive.
The per-nutrient table (rewritten)
This table used to publish absorption percentages comparing strips and capsules. Those numbers came from studies on other compounds, other doses and other products — not from testing on our strips — and presenting them as though they described our line was wrong. They're gone. Here's what honestly replaces them.
| Nutrient | Does the format change the biology? | What actually decides it |
|---|---|---|
| Vitamin B12 | Best-studied case. Controlled trials have generally found sublingual and oral B12 comparable at typical supplemental doses — not superior. | A reasonable option if tablets are a struggle. We have not tested our own finished product. |
| Caffeine | One of the few compounds with meaningful mucosal-absorption literature behind it. | We make no onset or absorption claim for our strips — we haven't measured it. |
| Melatonin | Also has mucosal-absorption literature behind it as a molecule. | Same caveat: not tested in our finished product, no onset claim. |
| L-theanine | No good evidence the route changes anything. | Format preference. Same amino acid either way. |
| Curcumin | Poorly absorbed generally; a film doesn't fix that. | Take it because you want it in the formula, not for the delivery route. |
| Mushroom extracts | No. Beta-glucans are large molecules acting on gut-immune receptors. | Gut-dependent by design. Taste and convenience are the real differences. |
| Iron | No. Uptake is hepcidin-regulated in the duodenum. | Tolerability and whether you'll keep taking it. Dose and form matter, not route. |
| Saffron | No. Needs gut hydrolysis to release its actives. | Flavour masking and dose accuracy. |
| Collagen peptides | No. Digested and absorbed via intestinal peptide transporters. | Whether you can stand a scoop of powder. Many people can't. |
| Vitamin D3 / K2 | No. Both need bile-salt micelles; trials have not found sublingual D3 superior to oral. | Pure preference. Dose is what matters. |
| Probiotics | No — the bacteria need to reach the intestine. | CFU count, strain, and whether you take it daily. |
| Calcium / magnesium | Capsule or powder. Dose is too large for a film. | Arithmetic, not pharmacology. |
| Fibre and prebiotics | Gut is the entire point. | Volume rules out a film completely. |
| Vitamin C | Absorbs adequately swallowed. | Cost. The capsule is cheap and fine. |
Read the table as: the route rarely decides anything; the ingredient, the dose, and your willingness to keep taking it decide almost everything.
Where the capsule still wins, in detail
This is the section every strip-company founder is supposed to skip.
Calcium and magnesium. A useful magnesium dose runs into the hundreds of milligrams. That does not fit on a thin film, and no amount of formulation cleverness changes it. Take the capsule.
Fibre and prebiotics. Volume alone disqualifies them. Capsules or powder.
Vitamin C. Cheap, widely available, absorbs fine swallowed. No reason to pay a format premium.
High-dose anything. If your target dose is over a gram, a film is the wrong vehicle. Not debatable.
Budget buying. A drugstore bottle will beat us on price per day, and I'd rather say that than pretend otherwise. Our strips are $29.99 for 30 — about a dollar a day, 10% less on subscription. That is more than a bottle of tablets. What you're buying is a format you'll actually use.
If your honest answer is "the capsule is fine," keep the capsule. The full per-nutrient format guide works through the same logic row by row.
The B12 question, answered properly
B12 is where the strip category makes its loudest claims, so it deserves precision.
The route is genuinely well studied. Controlled trials comparing sublingual and oral B12 have generally found the two comparable at typical supplemental doses. That's the actual finding, and it's a useful one: it means sublingual B12 is a reasonable alternative for people who find tablets difficult, without needing to invent a superiority story. Sublingual B12 has been used clinically as an alternative to injection for years on exactly that basis.
What I won't tell you is that our Energy strip — L-theanine, caffeine from green tea and B12 as methylcobalamin — delivers more B12 to your blood than a tablet does. We have not tested absorption in our finished product. Nobody selling you a strip has, unless they show you the data on that specific product.
And the ordinary caveat still applies: if you have a diagnosed B12 deficiency and your doctor has prescribed injections, take the injections. A daily strip is a supplement, not a treatment.
The cost reality nobody wants to talk about
This section used to contain a cost-per-absorbed-microgram calculation. It rested on absorption figures we've since retracted, so the calculation went with them. Here is the version that survives scrutiny.
A bottle of drugstore B12 tablets costs a few dollars and lasts months. A tin of XYNE strips is $29.99 for 30 strips — about a dollar a day, or roughly ten percent less on subscription. On raw price per day, the tablets win comfortably, and anyone telling you a per-absorbed-microgram calculation flips that result is doing arithmetic on numbers they didn't measure.
The case for paying more is simpler and, I think, stronger: a supplement only works if you take it. If pills are a fight, if you've abandoned three bottles in the last two years, if the powder tub is still three-quarters full — then the cheaper product has cost you everything you spent on it and delivered nothing. Adherence isn't a marketing angle. It's the only variable in this whole comparison that reliably changes outcomes. The bioavailability explainer covers why the dose on a label was never the dose in your blood, in any format.
The XYNE design philosophy, said straight
The lineup is deliberately not a strip version of every popular pill. We don't ship calcium or magnesium, because the dose doesn't fit. We don't claim our probiotic strip skips your gut — Bifidobacterium lactis at 10 billion CFU and 50 mg of polydextrose both work downstream, in the intestine and the colon, and that's how it's supposed to work.
What we do ship is a small line built around one problem: nothing to swallow. Each strip dissolves in about 30 seconds on a pullulan film base, needs no water, contains no sugar (stevia, monk fruit and erythritol do the sweetening), and lists every active with every dose our manufacturer has published — no proprietary blends. Where a dose hasn't been published, we say so instead of inventing a number. Designed in the USA and manufactured at a cGMP-certified facility specialising in sublingual delivery.
The line is small because the number of ingredients that genuinely suit a thin film is small. That's a constraint, and I'd rather name it than dress it up.
Frequently asked questions
Should I throw out my multivitamin and switch to strips?
No. A broad multivitamin does a job a strip can't — many nutrients, moderate doses, low cost. Keep it if it's working for you. Consider a strip for the things you've stopped taking because you didn't like taking them.
Do strips work for fat-soluble vitamins like D3 and K2?
They deliver them, yes, but through your digestive tract like any other format — both need bile salts to be absorbed. Trials have not found sublingual D3 superior to oral. Choose on preference and dose.
Is a strip stronger than a capsule at the same labelled dose?
No. Same dose, same ingredient. Anyone claiming a format multiplier should be showing you data on that exact finished product.
If sublingual is so good, why are pills still dominant?
Because pills are cheap to make, easy to dose, and work perfectly well for most people. Film is a newer, more expensive format that solves a specific problem: not everyone can, or wants to, swallow things.
Does it matter if I swallow while the strip dissolves?
Not much. Most of the dose is swallowed with saliva regardless, and for most of our actives that's the correct destination.
Can my kid take supplement strips?
Ours are formulated for adults. Ask your paediatrician before adding any supplement to a child's routine. Note especially that iron-containing products must be kept well away from young children.
The summary, in two sentences
Choose a strip when the format is the obstacle — you can't swallow pills, you hate powders, you want something you'll actually keep using. Choose a capsule when swallowing is easy, the dose is large, or price is the deciding factor, and don't let anyone sell you a switch on absorption numbers they haven't measured on the product in your hand.
That's the advice I gave my mom, and it's the advice I'd give you.
If you want a recommendation tailored to what you're trying to fix, take the quiz. If you'd rather just look, the strips are here.
