Nature’s Logic All Food Fortifier is a nutritious and healthy way to augment your pet’s diet. It contains many natural vitamins, minerals, and probiotics from 100% all natural food sources. Most pet food and supplements depend on fortification with synthetically manufactured vitamins, minerals, and amino acids. If accidentally overdosed, many of these synthetic forms of supplements are known to have toxic levels. Using real food concentrates as supplements alleviate any potential risk of overdosing these potentially harmful substances. Nature’s Logic All Food Fortifier is natural and safe to use with all breeds and sizes of dogs and cats.
