Do transdermal patches really work?

Yes. Transdermal delivery is one of the most effective ways to deliver nutrients and actives to the body — and it has decades of medical use behind it. At Everyday Lab we built our entire patch line on this principle.

The absorption hierarchy: not every format is equal

Here is the truth the supplement industry would rather not tell you: format matters more than dose. You can take the most expensive capsule on the market and absorb a minimal fraction of what you paid for. Or you can choose the right format and let your body make use of much more.

These are the formats from highest to lowest absorption — and why:

🥇 Vaginal collagen: up to 99% local absorption

The vaginal mucosa is highly vascularized — it is full of blood vessels just below the surface. When hydrolyzed collagen is applied vaginally, the peptides pass directly into the bloodstream without touching the digestive system. Local bioavailability is up to 99%. No other collagen format achieves this in the intimate area. Vaginal collagen is not a digestive supplement: it is direct tissue absorption.

🥈 Transdermal patch: up to 80% absorption

The active crosses the skin directly into the bloodstream. No digestive system. No first-pass metabolism. The active is released in a sustained way over hours, staying at stable levels in the blood. It is the format with the highest real bioavailability for actives such as melatonin, B-complex vitamins and natural antihistamines.

🥈 Sublingual liquid collagen: up to 80% absorption

By holding the liquid under the tongue for 30–60 seconds, the collagen is absorbed through the sublingual mucosa, which is extremely permeable and directly connected to the bloodstream. Sublingual collagen completely bypasses the digestive system, reaching the bloodstream in minutes, not hours. It is significantly superior to any capsule or powder.

❌ Powder dissolved in water and capsule: about 25% absorption

The least efficient formats. Powder and capsule depend on the digestive system: the acidic environment of the stomach and digestive enzymes degrade part of the peptides, and then comes first-pass liver metabolism. Gastric pH, the state of your microbiome and whether you ate beforehand directly affect how much you take advantage of. From a collagen capsule your body makes use of only about 25%. It is the most convenient format for the manufacturer, not for you.

Bioavailability comparison: the table that changes everything

Format	Estimated absorption	Does it go through digestion?	Verdict
Pill / capsule	~25%	Yes — first-pass metabolism	❌ Least efficient format
Dissolved powder	~25%	Yes — depends on gastric pH	⚠️ More convenient than the capsule, just as limited
Sublingual liquid collagen	Up to 80%	No — absorption through the sublingual mucosa	✅ Superior to capsule and powder
Vaginal collagen	Up to 99% local	No — straight into the bloodstream	✅ Maximum tissue absorption
Transdermal patch	Up to 80%	No — straight into the bloodstream	✅ Sustained and efficient release

Why is sublingual better than the capsule?

Under the tongue there is a dense network of blood vessels and highly permeable tissue. When liquid collagen is held on the sublingual mucosa, the peptides enter the circulation directly — within minutes. No acid. No digestive enzymes. No liver filtering what is left. The result is that the body makes use of up to 80% of what you take — compared with the 25% of a standard capsule.

Everyday Lab's Liquid Collagen Boost is formulated in this format for exactly that reason.

Why are patches better than capsules and powders?

The reason is simple: patches do not depend on the digestive system. The active crosses the skin through a controlled concentration gradient, entering the bloodstream directly at a constant rate over hours. There is no absorption variability depending on what you ate, your stomach acid levels or the health of your microbiome.

This is especially relevant for actives such as melatonin — where sustained release throughout the night is far more effective than a 30-minute peak from a capsule.

Does vaginal collagen really work?

Yes — and its absorption mechanism is unique. The vaginal area is lined with highly vascularized mucous tissue. Hydrolyzed collagen applied there does not need to be digested: it passes directly into the bloodstream and acts locally on the connective tissue of the intimate area. It may contribute to hydration, elasticity and comfort that no collagen capsule replicates, because no capsule gets there.

Everyday Lab's Ultimate Collagen Boost combines hydrolyzed collagen with hyaluronic acid to take advantage of this local effect. You can see how each absorption route works on our science page.

How much is absorbed from a patch vs a pill? — The direct answer

An Everyday Lab transdermal patch has up to 3 times more bioavailability than an equivalent capsule or pill. The pill reaches your blood with about 25% of the original active. The patch arrives with up to 80%.

It is not marketing. It is physiology.

Why does Everyday Lab use these formats — and not capsules?

Because we believe that if you are going to take a supplement, it has to get there. We chose transdermal patches, sublingual collagen and vaginal collagen not because they sound good, but because they are the routes with the highest real bioavailability.

• Hangover Recovery Patch — B-complex vitamins and antioxidants via the transdermal route
• Recharge Sleeping Patch — sustained-release melatonin throughout the night
• Anti-Nausea Motion Sickness Patch — nausea relief without drowsiness
• Cool-ing Patch for Kids — locally acting cooling gel for fever in children
• Liquid Collagen Boost — high-absorption sublingual collagen
• Ultimate Collagen Boost — vaginal collagen with hyaluronic acid
