Animal Essentials’ Olive Leaf Herbal Tonic is a thoughtfully crafted single-herb supplement designed to provide gentle yet effective immune system support. Sourced from organic Olea europaea leaves, this tonic taps into the time-honored wellness benefits of olive leaf—an herb revered in Mediterranean herbal traditions for its role in promoting internal balance, vitality, and resistance to environmental stress.

Olive leaf contains oleuropein, a powerful antioxidant compound known to help protect cells from oxidative stress and support the body’s natural inflammatory response. These actions make it especially valuable during times of immune challenge, such as exposure to unfamiliar environments, travel, boarding, or seasonal shifts. In addition to its immune-supportive properties, olive leaf is often used to promote the body’s innate resistance to pathogens.

Because it's made with a gentle glycerin base and free from alcohol, this formula is suitable for long-term use—even for senior pets or those with sensitivities. Whether you’re enhancing your pet’s immune system during cold seasons or building a foundation for lifelong health, Olive Leaf Herbal Tonic is a trusted botanical ally for daily wellness.

Animal Essentials’ Olive Leaf Herbal Tonic is made with simplicity, purity, and purpose in mind. We source only whole, certified organic olive leaves—never isolates or synthetic extracts—ensuring your pet receives the full spectrum of naturally occurring compounds that support immune health. Our glycerin-based formula is crafted without alcohol, preservatives, or unnecessary fillers, making it safe for pets of all ages and easy to administer.

    I read that Olive Leaf is really good for protecting pets from pathogens. I am giving this to our oldest cat to keep him healthy as he ages. I add it to his food and he has no problems with it.
