NAC, Canine n-Acetyl-Cysteine or Simply: NAC For Dogs.

NAC Canine n-Acetyl-Cysteine NAC For Dogs.

I’ve had questions about NAC. And there’s a LOT of hype and “buzz” around it.

First, “What is n-Acetyl cysteine (NAC)?”

It’s an Amino Acid. It’s rich in cysteine and serine. Yay!

We used to use n-Acetyl cysteine as an “inhaler” and it would VERY effectively break down and move out mucus in the lungs and bronchi.

Then I guess someone thought: “We should inject n-Acetyl cysteine into dogs, and feed it to them. And just see what happens.

And found out that it’s “magical” and benefits practically everything they tried it on. (150mg/20lb Once a Day at least, all the way up to 100mg/lb is recommended in some places.)

My recommendation:   20mg per pound once or twice a day. 60 lbs = 1200mg once a day.

I mean, n-Acetyl cysteine kills effing GERMS!!! It boosts the number and function of anti-oxidant producing cells and production in the body. n-Acetyl cysteine’s used in airway AND neurological injury. It can help the liver to heal, to survive intoxication, and to help restore function.

And, n-Acetyl cysteine has all the benefits of other “big time” antioxidants. It’s a precursor to Glutathione, the OG (original gangsta) of antioxidants.

Dosing NAC In Dogs

Green is the recommended dose for the dog. In yellow is a higher-end dose and caution could be exercised as it’s possible to upset the stomach with NAC in the higher dose ranges. Where to get NAC Quickly, Affordably and Safely
