Generally, many animals that are suffering from symptoms of a leaky gut, yeast, allergies & more may achieve the desired relief and healing with just one protocol. Pets who have deeper rooted issues may require ongoing support or multiple kits. You should see gradual improvement as long as you are using it.
If the improvement stops or conditions appear to be worsening, you may need to go back to the previous 2-week interval. Once your animal improves completely on the protocol, it is always a good idea to do Leaky Gut Protocol once a year to help keep the gut in prime condition.
