NAC Supplement Buying Guide

For years, doctors have used N-acetylcysteine, or NAC, to treat a wide variety of conditions, including heart, lung, and even mental health. 

More recently, however, researchers have lasered in on NAC's amazing immune-boosting capabilities

Today NAC is more popular than ever among people seeking a natural approach to immune health. Unfortunately, this has lead to a market surplus, forcing consumers to sift through poor and mediocre NAC products. 

We're here to cut through the noise and confusion. After analyzing dozens of brands, we've compiled a list of our top 5 favorite NAC-containing supplements the market has to offer. 

What is NAC and how does it work? 

NAC is the supplemental form of L-cysteine, a semi-essential amino acid present in our bodies. Over the decades it's been used to treat a host of medical issues, including chronic lung disease and addictive behavior.

In fact, the effectiveness of NAC is so well-documented, the World Health Organization has designated it an "essential medicine." NAC is making headlines once again, this time thanks to its immune-boosting capabilities.

Specifically, NAC is valued for its role in producing a powerful antioxidant called glutathione (GHS). Often dubbed the "master detoxifier," GHS eliminates free radicals and heavy metals from the body and protects against the harmful effects of inflammation.

Over time, your body produces less of this vital antioxidant. However, studies have shown that taking NAC can boost GHS production

P.S., Don't Forget About The Liver!

The liver is an integral part of your immune system. In addition to flushing toxins out of your body, it also keeps your oxidant levels in check.

NAC can help detoxify the liver in addition to repairing damaged liver cells. We suggest going the extra mile and looking for a supplement that pairs NAC with complementary ingredients that can boost liver health and fortify the immune system

What to look for and what to avoid in your NAC supplement

  • Look For
  • A supplement with at least 600 mg of NAC per serving. Studies suggest this is the smallest effective dose. 
  • Milk Thistle - can help reduce damage caused by free radicals and toxins. 
  • Zinc - plays a key role in promoting immune health and reducing inflammation.
  • Selenium - can help heal and detoxify your liver. 
  • Avoid
  • Magnesium Stearate - used to bind ingredients together but can cause more harm than good.
  • Titanium Dioxide - used as a coloring agent and binding mineral, titanium dioxide can compromise the health of your immune system. 

What Else To Consider Before Buying NAC
