Our NAC capsules (600mg per capsule) have been formulated for use by humans but can be safely used by pets, with vets often recommending NAC supplementation. For use with pets we would recommend the following daily usage instructions:

Cats: 1/4 capsule daily (in food)

Dogs: 1/4 capsule for each 20 lbs of body weight (in food).

Please Note: Dosage instructions on the bottle are for human use. Please use the dosage instructions above for use with dogs and cats.
