Best Product!

"Archie is my 2 1/2-year-old cream colored golden doodle. So I wondered about the dark fur around his mouth and paw. His vet said it was from yeast in his body/G.I. system. We tried another product which helped a little. After speaking with the proprietor of a wonderful pet supply store in Deland Florida, I tried Yeast Guard. Archie’s vet wholeheartedly approved of the product. And now all that dark hair/fur is back to its natural color! Terrific product! Thank you!"

Premium Ingredients

Pau d'arco
Pau d'arco

Pau d'Arco, derived from the bark of the Tabebuia tree, contains compounds such as lapachol and beta-lapachone, which benefit gut health by helping to manage harmful bacteria and yeast populations in the digestive tract and promote a healthy balance of gut flora. Additionally, Pau d'art can help soothe irritation in the gastrointestinal tract.

Organic goldenseal
Organic goldenseal

Goldenseal is renowned for its gut health benefits, primarily due to its active compound, berberine, which supports a healthy gastrointestinal microbiome. It also promotes healthy digestion and enhances the quality of the mucous membranes, supporting the overall health of the digestive system.

Because we use only sustainable ingredients, we don't use wildcrafted goldenseal because it is considered an at-risk species due to over-harvesting. Choosing cultivated goldenseal not only supports conservation efforts but also ensures that the product is free from contaminants that might be present in wild populations, making it a safer and more ethical choice.

C8/C10 MCT powder
C8/C10 MCT powder

Medium chain triglyceride (MCT) oil is highly beneficial for gut health and managing yeast issues due to its concentrated content of caprylic (C8) and capric (C10) acids. These medium-chain fatty acids have been shown to help the body detoxify from yeast overgrowth. Additionally, MCT oil can help balance the gut microbiome and enhance digestion and nutrient absorption.

Our MCT oil is free of lauric acid because it is metabolized like a long-chain fatty acid in the body, requiring a more complex process for digestion and absorption. We use only caprylic (C8) and capric (C10) acids to ensure faster and more efficient absorption, bypassing the slower metabolic processes associated with long-chain fatty acids and minimizing digestive stress.

Organic olive leaf
Organic olive leaf

Olive leaf extract benefits gut health by discouraging the proliferation of harmful bacteria and yeast in the digestive tract and promoting a healthy balance of gut flora. The active compound oleuropein, also supports the immune system, enhancing the body's ability to defend against gastrointestinal issues. Additionally, its antioxidant effects can protect the gut lining from oxidative stress and damage, further supporting the integrity and function of the digestive system.

Organic ginger root

Supports a healthy skin and gut biome and helps reduce oxidative damage.

Organic fennel

Fennel seeds are beneficial for gut health and detoxification from yeast overgrowth. Fennel seeds also contain anethole, a compound that can help soothe the digestive tract and relax the smooth muscles of the gastrointestinal system, improving overall digestion and contributing to a healthier gut environment.

Additionally, oregano leaf can aid in alleviating digestive discomfort and supporting the immune system, making it a valuable natural remedy for improving gut health and addressing yeast overgrowth.

Who We Are

In Memory of Simon & Aaron

The story of Four Leaf Rover started as a tragedy. Our founder Dana Scott lost two dogs from toxic sprays they were exposed to in the fields surrounding her home. In a frantic effort to save her dogs and protect her remaining dog family, Dana connected with most of the leading holistic veterinarians around the world about the most effective natural remedies. As Dana researched remedies, she found nearly all contained hidden or harmful ingredients. Four Leaf Rover began as a promise to Dana's lost dogs that all dogs deserve super premium products with natural ingredients that are thoroughly tested to be low in harmful pesticides and heavy metals. With a mission of quality, transparency and sustainability, Four Leaf Rover is making the world a better place for dogs and the people who love them.
