"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!"

Ingredients
Pau d’arco comes from the inner bark of the Tabebuia tree, a staple of traditional South American herbalism. Its compounds lapachol and beta-lapachone support a healthy balance of gut flora. And a balanced gut is where healthy skin starts.
Goldenseal’s star compound is berberine. It helps maintain a healthy gut microbiome and the mucous membranes that line your dog’s digestive tract.
But there’s a catch. Wild goldenseal is an at-risk species, thanks to decades of overharvesting. So we only use cultivated goldenseal. It’s better for the plant … and it’s free of the contaminants wild sources can carry.
Not all MCTs are created equal. Ours contains only caprylic (C8) and capric (C10) acids, the medium chain fats your dog’s body absorbs and uses quickly. We leave out lauric acid (C12) on purpose. It’s technically an MCT, but your dog digests it like a long chain fat (the slow route). C8 and C10 help maintain a balanced microbiome and easy digestion.
Olive leaf is rich in oleuropein, a powerful antioxidant. It supports normal immune function and helps protect the gut lining from everyday oxidative stress.
A little ginger goes a long way. It supports healthy digestion and adds antioxidant support for skin and gut.
Fennel seed gets its sweet licorice flavor from anethole. That same compound supports digestive comfort and a calm, settled gut.
Oregano and thyme share two key plant compounds: carvacrol and thymol. Oregano is the carvacrol heavyweight. It helps maintain a balanced gut microbiome and normal yeast levels.
Thyme brings the thymol. Paired with oregano, it rounds out the formula’s microbiome support and promotes healthy digestion.

How To Get Best Results
An unbalanced gut environment can create conditions that favor yeast overgrowth. Yeast Guard is veterinarian formulated with organic botanicals to help maintain a healthy intestinal environment and microbial balance. For best results, feed your dog a healthy diet low in carbohydrates and follow this simple progression plan:
Follow the label directions and give Yeast Guard daily with food. For best results, feed with a fresh food diet such as Meat Mixer. Initial changes may be seen in the first week, but continued daily use is often needed to support more noticeable changes.
Maintain daily use for 30 to 60 days. Many dogs show benefits earlier, but we recommend the full 60 days for lasting results. If small benefits don’t appear within 30 days, add Gut Guard daily to support the gut lining.
Once your dog completes the full 60 days of Yeast Guard and you are happy with the results, transition to Protect for ongoing gut and microbiome support. Protect helps maintain a healthy gut lining and a balanced microbiome and should be used as part of your dog’s daily routine.

Yes. It can be used long term, especially for dogs eating processed diets or dogs exposed to everyday toxins.
Yeast Guard contains a small amount of goldenseal root powder. California placed goldenseal root powder on its Proposition 65 list in 2015, so we provide the warning as a conservative compliance measure.
The warning does not mean Yeast Guard has been found to cause cancer or that it is unsafe for dogs when used as directed.
California’s listing was based on a two year laboratory study in rats and mice. The animals were fed diets containing goldenseal root powder every day for essentially their entire lives. At the highest exposure, goldenseal made up 2.5% of everything they ate. That translated to daily doses as high as approximately:
- 1,175 to 1,340 mg per kilogram of body weight in rats
- 2,875 to 3,275 mg per kilogram of body weight in mice
Those amounts bear little resemblance to the small, measured quantity of goldenseal contained in a serving of Yeast Guard.
The results were also not uniform. Liver tumors increased in rats at the highest concentration and in male mice, while the study found no evidence of carcinogenic activity in female mice. Goldenseal root powder and its major constituent, berberine, were also negative in the genetic toxicity tests reported with the study.
There is inadequate evidence that goldenseal causes cancer in humans. Nevertheless, California’s unusually broad warning law permits an ingredient to be listed based on animal studies involving exposure levels and conditions that may be dramatically different from normal product use.
Proposition 65 is concerned with human exposure, even though Yeast Guard is formulated for dogs. The amount of goldenseal a person could encounter while measuring a normal serving is extremely small. However, California has not provided a simple safe harbor level for goldenseal root powder, and establishing that a warning is unnecessary can require costly product-specific exposure testing and legal analysis.
We use goldenseal as one carefully measured component of Yeast Guard’s herbal formula. The Proposition 65 warning is a conservative legal disclosure—not evidence that the small amount in Yeast Guard presents a meaningful cancer risk during normal use.
