Summary
In this episode, Dr. Ruscio breaks down the surprising gut and systemic benefits of NAC (N-acetylcysteine), including how it may help break down biofilms, support SIBO and H. pylori treatment, improve gut lining repair, boost nutrient absorption, and support glutathione, mitochondria, and brain health. You'll also learn when sustained-release NAC may be useful, how to dose NAC properly, and what side effects or cautions to keep in mind.

| 0:25.8 | Today, let's cover the gut health benefits of NAC and Acidyl Cysteine, which include its |
| 0:30.6 | antibacterial action, anti-cebo action, anti-biofilm properties, the ability of NAC to improve nutrient absorption, the ability |
| 0:41.6 | of NAC also to improve leaky gut, and to repair the gut lining benefits for inflammatory bowel |
| 0:48.9 | disease as well. Well, the next cover systemic benefits, which include increasing glutathione status in the brain, |
| 0:56.6 | some very interesting first-time findings there. |
| 1:00.1 | Additionally, benefits for fatigue, mitochondrial function, brain health, and immune health. |
| 1:06.4 | We'll then close our discussion with how to supplement properly, including protocols for use. |
| 1:12.6 | The form does matter for the use case, dosing guidelines, and also safety and side effects. |
| 1:19.9 | If you're new here, welcome. I'm Michael Rucho. I'm a doctor in private practice, an adjunct professor, |
| 1:26.8 | and a clinical researcher. |
| 1:28.4 | I see patients, teach students, and publish research, all in the field of integrative and |

| 1:35.7 | Let's begin our discussion with H. pylori or helicobacter pylori. |
| 1:41.2 | This is a bacteria that can infect the lining of the stomach and or the small intestine. |
| 1:49.2 | And because of this, it can cause ulcer in the stomach or the small intestine. But additionally, |
| 1:55.4 | cancer, nutrient malabsorption, including iron, and potentially fatigue secondary to that malabsorption. |
| 2:03.6 | So this is certainly something that if we can use a simple, safe, natural supplement like |
| 2:08.7 | NAC, then there's several, there's a subset of the population this may benefit. |
| 2:15.5 | Now, mechanistically, N.Sidyl Cysteine or knack is a mucolytic, meaning it breaks |
