Suggested Use

  • Supplementation can begin with a high dosage until tumors regress and condition improves, after which, dosage can be reduced by 50% to maintain the health status.
  • Unless remission is longer than 6 months, it is recommended to continue giving these supplements to facilitate the functions of the immune system and help prevent recurrence.
  • Given orally between meals or crumbled and mixed with moist food.
  • When a dog's immune system is being severely challenged, additional support can be given by doubling the suggested amount for 3-6 months.
  • Responses to natural dietary supplements may vary by animal.
