Can Broccoli Really Help Prevent Cancer in Dogs?

26 June

Here’s what you need to know about sulforaphane, the antioxidant that’s quietly gaining attention in canine cancer prevention.

Sulforaphane is a powerful antioxidant found in broccoli
It helps protect your dog’s cells from DNA damage
New research shows it may support cancer prevention in pets
You can get it through diet (if your dog tolerates broccoli) or a pet-safe supplement like Avmaquin™

What Is Sulforaphane (And Why Are Vets Talking About It)?

Sulforaphane is a natural antioxidant that builds up in the body and acts like a cellular shield.

It helps neutralise toxins and defend against free radicals — unstable molecules that can damage DNA and increase the risk of cancer over time.

It’s like an internal clean-up crew, quietly protecting the body at a microscopic level.

When your dog eats cruciferous veggies like broccoli, their body produces sulforaphane.
It builds up in their blood and urine, helping repair and protect cells.
Antioxidants like this have been linked to improved cellular health, reduced inflammation, and potential cancer prevention.

Broccoli is the go-to vegetable when it comes to sulforaphane.

But not every dog wants a floret with dinner (and not every tummy tolerates it).

That’s where safe, targeted supplements come in.

Supplements like Avmaquin™ are designed to deliver sulforaphane in a pet-friendly, effective way — without needing to change your dog’s diet.

✔️ Vet-formulated

✔️ Easy to give

✔️ Backed by emerging science

(And yes, humans can take sulforaphane supplements too!)

If you’re caring for a senior dog, a cancer-prone breed, or just want to support your pet’s long-term wellness, this is a tool worth knowing about.

It’s gentle. It’s preventative. And it’s part of a growing movement toward nutritional medicine for pets.

Not every dog will be thrilled about a bowl of steamed broccoli — and some may not tolerate raw cruciferous veggies well.

The good news is, there are gentle, pet-safe ways to add sulforaphane to your dog’s diet.

Choose a Food That Already Contains Broccoli
One of the easiest and safest ways to include sulforaphane is through dog foods that already incorporate broccoli in a balanced, vet-formulated way.
Example: Prime Pantry Chicken with Broccoli & Apple Roll. This complete and balanced roll includes gently cooked broccoli alongside Australian chicken, apple, peas, and carrots. It’s a great option if you’re looking to support your dog’s health with minimal fuss and maximum nutrition — no sneaky veggie disguises required.
Lightly Steamed Broccoli (in moderation)
If your dog tolerates it, a small amount of lightly steamed broccoli can be a simple topper to their usual food. Avoid feeding raw, and stick to just a few florets at a time. Always introduce new foods slowly and observe for any tummy upsets.
Consider a Sulforaphane Supplement
If you’re aiming for a more concentrated and consistent source, sulforaphane supplements like Avmaquin™ can offer targeted cellular support. This option is ideal for pets with specific health concerns or for families already using supplements as part of their wellness plan.

Sulforaphane isn’t magic. But it is meaningful.

And in a world where chronic illness is on the rise — for both humans and animals — these little things add up.

Because sometimes, a bit of broccoli can go a long way.
