We spend a lot of time thinking about what goes into our skincare, but there’s another part of the equation that doesn’t get talked about as much: what went into the animal that produced the ingredient in the first place.

So, does what cattle eat actually affect tallow? Of course! An animal’s diet can influence the composition of its body fat, which is one reason we pay attention to how the cattle behind our tallow are raised and fed. That doesn’t mean grass-fed automatically makes tallow “better for your skin” and we’re not interested in making claims that go beyond what we actually know. We simply think the source of an ingredient is worth knowing.

What Does Grass-Fed Actually Mean?

Grass-fed, grass-finished and pasture-raised are terms you’ll see a lot when shopping for beef and tallow, but they don’t all mean the same thing. Grass-fed generally refers to cattle eating grass or forage as part of their diet. Grass-finished means they remain on a grass-based diet through the finishing stage, while pasture-raised describes how and where the cattle are raised.

So when we say our tallow comes from 100% pasture-raised, grass-fed, grass-finished beef, we’re being specific about where it comes from and how those cattle were raised. That matters to us.

What Cattle Eat Can Influence Their Fat

Tallow is, after all, the fat from cattle. Research has found that an animal’s diet can influence the fatty acid composition of its fat, although that doesn’t mean you can look at a jar of tallow and know exactly what the animal ate or predict how it will perform on someone’s skin.

There are a lot of variables, including the type of fat used, how it’s rendered and how the finished tallow is formulated. But the basic idea makes sense to us.Think about humans for a second. What we eat tends to affect how we feel and, for many of us, how we look, too. If you’re living on greasy takeout and ultra-processed food every day, you might feel sluggish, foggy and generally off. Eat a more balanced diet for a while and you’ll often notice a difference in your energy, how you feel and sometimes your skin, too.

It’s not about eating perfectly. It’s about recognizing that inputs matter. We think the same way about the ingredients we choose for our skincare.

Why We Use Beef Kidney Suet

At Ocasa Botanica, we use beef kidney suet as the starting point for our tallow. Suet is the firm fat found around the kidneys and other internal organs of cattle, and it has traditionally been valued for rendering. We specifically source 100% pasture-raised, grass-fed, grass-finished beef kidney suet because we want to know what we’re starting with before it ever becomes a skincare ingredient.

Of course, sourcing isn’t the whole story. How the fat is handled, rendered and formulated matters, too. But we think good skincare starts with good ingredients and a little transparency about where they come from.

Grass-Fed Tallow Isn’t A Miracle Ingredient

There’s plenty of marketing around grass-fed tallow that makes some pretty big promises. We’re not going to tell you that grass-finished tallow is automatically more nourishing or that it will produce some guaranteed result for your skin.

The reality is more nuanced. Diet can influence the composition of animal fat, but that’s just one piece of the picture. For us, choosing grass-fed, grass-finished, pasture-raised beef is less about making a dramatic skincare claim and more about being intentional about our sourcing.

We’d rather tell you exactly what we choose and let you decide what matters to you.

What To Look For In Tallow Skincare

If you’re buying tallow cream, “beef tallow” on the label doesn’t tell you the whole story. Take a look at where the tallow comes from, what part of the animal is used, how it’s sourced and what else is in the formula. If a brand says its tallow is grass-fed or grass-finished, see if it actually explains what that means. For us, transparency is part of the product.

So, Does What Cattle Eat Affect Tallow?

It can. An animal’s diet can influence the composition of its fat, which makes sourcing worth paying attention to when you’re choosing tallow skincare. But we think the bigger takeaway is pretty simple: know where your ingredients come from. For us, that means starting with 100% pasture-raised, grass-fed, grass-finished beef kidney suet and being thoughtful about every step that comes after it.

Tallow doesn’t need a complicated story. We just think it’s a better one when you know where it started.
