This whole food supplement is extremely nourishing, containing more than 20 wildcrafted or organic herbs, nutritional yeast, bee pollen, garlic and spirulina. Because this product is composed of herbs and other whole foods, it will supply nutrients that support healing and organ function without overwhelming your animal's body. I highly recommend this product for all dogs and cats, and especially for those that are recovering or out of balance. Since greens are loaded with enzymes, they actually aid digestion and create a more nutritious synergy from the foods that they are combined with. And greens are powerful detoxifiers! For an immune-impaired 22-pound dog, I feed 3 or 4 small, nutrition-packed meals about 3-4 hours apart that always include powdered greens in some form. I rely heavily on Dr. Harvey because his Multi-Vitamin Mineral & Herbal supplement contains herbs that support the liver and other organs, are loaded with healing enzymes, and my puppy loves this stuff! She often has 3-4 scoops of this per day - one scoop with each "power meal."
