Most canine supplements begin in the same place: the mouth.
Chews, capsules, tablets and powders dominate the category, so giving a dog a supplement has become almost synonymous with getting them to eat something.
Tvati takes a different approach.
Rather than adding another product to the food bowl, Tvati Pet is a simple topical oil applied directly to the skin.
Why?
Because how an ingredient is delivered matters just as much as what is inside the product.
What does topical actually mean?
A topical product is simply one that is applied directly to the skin.
That might sound straightforward, but the skin itself is anything but simple.
It is a complex biological organ designed primarily to protect the body from the outside environment.
The outermost layer, known as the stratum corneum, forms an especially effective barrier.
This is why applying a substance to the skin does not automatically mean that it will pass through it.
Whether a compound can penetrate the skin depends on factors including:
- molecular size;
- chemical structure;
- lipid solubility;
- concentration;
- the carrier or vehicle used;
- the condition of the skin;
- and the site of application.
In other words, formulation matters.
Topical and transdermal are not quite the same thing
The terms topical and transdermal are often used interchangeably, but scientifically there is an important distinction.
Topical describes where a product is applied.
Transdermal describes movement of a substance across the skin barrier.
Some topical products are specifically designed to act on the surface of the skin. Others are formulated to encourage particular compounds to penetrate further into or through the skin.
This principle is well established within both human and veterinary medicine, but that does not mean every substance applied to the skin will behave identically.
The properties of the individual compound and the finished formulation determine what happens next.
Why Tvati uses an oil-based formulation
Tvati Pet contains just two ingredients:
- Cook Islands Sea Hibiscus oil;
- organic coconut oil.
The coconut oil acts as the carrier for the hibiscus ingredient.
Both the botanical and its carrier are lipid-based, which is relevant because lipid solubility is one of the factors influencing how compounds interact with the skin barrier.
The role of a carrier is not simply to dilute another ingredient.
Within any topical formulation, the carrier affects:
- how easily the product spreads;
- how closely it contacts the skin;
- the stability of the formulation;
- and how the compounds within it are presented to the skin barrier.
That is why the finished formula needs to be considered as a whole rather than looking at its individual ingredients in isolation.
The skin is selective
One of the most useful ways to understand topical delivery is to stop thinking of skin as either completely permeable or completely impermeable.
It is selective.
Different molecules interact with it in different ways.
Smaller compounds may behave differently from larger ones. Lipid-soluble compounds may behave differently from highly water-soluble compounds. Different carriers can also alter the way an ingredient sits on and interacts with the skin.
This is why responsible formulation research needs to investigate a specific product, rather than simply assuming that an ingredient will be absorbed because it has been applied topically.
Why choose the skin instead of the digestive system?
Oral supplementation is familiar and can be highly effective.
There is nothing inherently wrong with using a chew, capsule or powder.
But the oral route introduces a particular set of practical and biological considerations.
An orally administered ingredient must first be consumed.
That means palatability becomes part of the formulation challenge.
The product may require flavouring or a food-like matrix, and the owner depends on the dog willingly consuming the full amount.
After ingestion, compounds encounter the gastrointestinal tract, where digestion, intestinal absorption and metabolism influence what ultimately becomes biologically available.
A topical approach removes the requirement for the supplement itself to be eaten.
For Tvati, that provides several practical advantages:
- no chew needs to be accepted;
- no tablet needs to be hidden;
- the routine does not depend on appetite;
- no flavouring is required purely to encourage consumption;
- and application can remain consistent even in dogs that are selective around food.
Why consistency matters
For products designed to support long-term health, consistency matters enormously.
A beautifully formulated supplement provides little value if administration becomes a daily battle.
This is particularly relevant in older dogs, where appetite and food preferences can change over time.
A topical routine separates supplementation from feeding.
That means Tvati can be applied independently of whether the dog has eaten breakfast, finished dinner or decided that today's carefully disguised tablet is no longer acceptable.
There is a useful behavioural advantage here as well.
A quick application to the skin can become part of an everyday care routine rather than an exercise in persuasion.
Why a two-ingredient formula?
Oral products often need additional ingredients for perfectly sensible manufacturing reasons.
A chew needs structure and palatability. A tablet needs to hold together. A flavoured product needs to taste appealing enough for the animal to consume it.
Tvati does not have those requirements.
Its topical format allows the formulation to remain extremely simple:
- the Sea Hibiscus oil at the centre of Tvati's research;
- and organic coconut oil as its carrier.
A short ingredient list is not automatically better than a longer one.
What it does mean is that every ingredient has a clearly defined reason for being there.
Does topical automatically mean better?
No.
And that distinction is important.
Different delivery systems suit different compounds, products and animals.
Oral supplementation has an extensive history in both veterinary medicine and nutrition. For many ingredients, it remains entirely appropriate.
The value of topical delivery is not that the skin is somehow universally superior to the digestive system.
The question is whether the ingredient, formulation and route of administration work appropriately together.
That is the scientifically interesting part of Tvati.
Rather than selecting an established oral supplement and simply changing its format, Tvati has been developed around a lipid-based botanical ingredient and a topical oil formulation.
What about first-pass metabolism?
One reason transdermal drug delivery is used in medicine is the potential to avoid the gastrointestinal tract and the initial hepatic processing associated with orally administered compounds.
This is commonly referred to as first-pass metabolism.
However, this principle needs to be applied carefully when discussing individual products.
The fact that established transdermal medicines can bypass first-pass metabolism does not automatically prove that every topical botanical formulation achieves systemic delivery.
That depends on the specific compounds involved and whether they cross the skin barrier in meaningful quantities.
For Tvati, understanding the behaviour of its own formulation is therefore more meaningful than simply pointing to unrelated patches, gels or veterinary spot-on products.
This distinction is important for scientifically responsible communication.
Formulation is part of the research
Tvati's Cook Islands hibiscus has been investigated through a research programme associated with the University of New South Wales.
Part of understanding a novel botanical involves investigating not only the ingredient itself, but how it behaves when incorporated into a finished formulation.
Relevant questions include:
- which compounds are present;
- their physicochemical properties;
- how they interact with the carrier;
- how stable the formulation remains;
- how the product interacts with the skin;
- and what further work is required to understand delivery and biological activity.
This is an evolving evidence base.
That is exactly what should be expected when investigating a relatively novel botanical and delivery approach.
Simple for the owner. More complex underneath.
From the owner's perspective, Tvati is intentionally straightforward.
Part the coat. Apply the product directly to the skin. Make it part of the routine.
But simplicity of use should not be confused with simplicity of formulation.
Behind a topical product sits a series of questions involving chemistry, skin biology, botanical composition and delivery.
Those are the questions that make the format scientifically interesting.
Why topical?
Because the best route of administration is not always the most familiar one.
Tvati was designed around a botanical oil, an oil-based carrier and a simple application that does not rely on appetite, flavour or another daily chew.
It gives owners a different way to incorporate joint and mobility support into everyday care.
And while the routine itself takes only seconds, the science behind topical formulation is considerably more interesting than it first appears.
For Tvati, that combination is the point.
Simple to give. Easy to make part of every day. Designed to support more of the movement and moments that matter.
For more good days.
