About Twell

Twell is an immune wellness brand for dogs. We are dog owners and dog lovers and we come with decades of experience in crafting immune support products for both the human and animal markets.

What's in a name?

For us, pretty much everything! Twell is short for "T-cell wellness" and, in the simplest terms, it's what we do and how we do it.

We believe so strongly that Thymic Protein A (TPA) is the single best supplement/ingredient to help support your dog's immune system, that it's 100% of our business. Why TPA? Because it's the specific (and only) protein responsible for activating immature T-cells, turning them into mature, fully functioning T-cells.

And why T-cells? Because, as the National Library of Medicine puts it, "the establishment and maintenance of immune responses, homeostasis, and memory depends on T cells."
