N-Acetyl L-Cysteine Powder

  • Product Description


    N-Acetyl L-Cysteine, also known as Acetylcysteine or NAC, is an acetylated form of L-Cysteine. It is used primarily as a mucolytic agent as well as for sulfate repletion. N-Acetyl L-Cysteine is also used to enhance the production of glutathione when it is normally depleted.

    N-Acetyl L-Cysteine Benefits and Uses

    • Supports respiratory health
    • Promotes skin health
    • Supports organ health
    • Promotes energy

    What is N-Acetyl L-Cysteine Good For?

    Studies observing glutathione levels after taking an n-acetyl l-cysteine supplement found that N-Acetyl L-Cysteine elevated glutathione levels. This is significant because the supplementation of glutathione on its own did not significantly increase glutathione levels. Since N-Acetyl L-Cysteine is able to increase glutathione, N-Acetyl L-Cysteine benefits have been linked to skin, and organ health and promoting energy. Additionally, taking an N-Acetyl L-cysteine supplement is believed to have some detoxification effects since it allows more glutathione to be produced.

    In addition, N-Acetyl L-Cysteine benefits include organ protective properties when exposed to alcohol. A study on rats found that a NAC supplement taken 30 min before alcohol exposure seemed to produce a protective effect while administration 4 hrs after alcohol exposure elevated organ tissue damage. Additionally, these protective behaviors increased when alcohol consumption was stopped.

    Other N-Acetyl L-Cysteine uses were studied after the relationship between glutathione and NAC supplement were established. Researchers were interested in N-Acetyl L-Cysteine for its potentially energizing effects. Studies on sprint performance found energizing effects when subjects used a NAC supplement but only a slight increase in energy from baseline was achieved with a large dose.


    The body converts N-Acetyl L-Cysteine which converts into cysteine which is converted to glutathione. Cysteine is an amino acid produced by the body but it requires methionine to do so. Cysteine is primarily found in animal proteins such as chicken, pork, sausage, turkey, fish and duck. Dairy sources of cysteine include yogurt, ricotta cheese, eggs, and cottage cheese. Cysteine is also found in some plant sources for vegetarians and vegans. Foods such as broccoli, red pepper, onion, granola and oat flakes are all good sources of cysteine. Other sources include garlic, bananas, linseed, soy beans, and wheat germ. Low levels of cysteine can delay growth in children and lower immunity. Weakness, muscle loss, and liver damage can also occur as a result of a low cysteine diet.


    As a dietary supplement, take one 500mg of N-Acetyl L-Cysteine once daily.

    1. "Better" for nasal congestion

      NAC is the supplement of choice for helping to mitigate nasal congestion. I've found even with a cold, taking a large dose divided up into several small doses separated by 2-4 hours throughout the day significantly controls the nose situation. Recently while going through this routine, I also noticed heightened mental clarity which quickly was attributed to the NAC as nothing else in my regular stack had changed. Combined with the fact the loose powder is inexpensive, NAC has high opinion from me.

      Con, it tastes terrible. It seriously tastes like butt if that was made from rubber. Capsulating it yourself is highly recommended!

    2. its hard to argue with the research

      NAC might be the most beneficial supplement for the money. It’s hard to be objective about the way it’s effected me so far but it does seem to help to some extent with mood and thinking. There’s a laundry list of studies showing that it’s effective for a wide spectrum of things. Very interesting compound. on 9th Apr 2018

    3. Pure and Cleansing

      NAC is an essential part of my daily routine. I take 2000mg every morning and if I feel a cold coming on I also take 1000 or 2000mg of an evening. Every winter I get a cold which precipitates a severe chest infection. It is now halfway through winter and I have not yet even caught a cold, despite the fact that the rest of my family has been sick with colds. My nose usually runs all winter but the mucous dissolving properties of NAC somehow even ameliorate that. I use Nootropics Depot's NAC because I know it's pure and independently tested. It comes in user friendly packaging, it's inexpensive, the postage is tracked and it arrives quickly. on 11th Jul 2017

    4. Great product

      This is such a must have product for your body. I take about 1500 mg a day divided in two doses (750 each). The product seems to be of very good quality, crystalline substance. on 23rd Feb 2017

    5. Beautiful crystalline structures

      What amazing quality. I've tried other brands of NAC, but this one seems to have a purer smell and look. At least as reliably as I'm used to. @ 1200 mg once or twice per day, 3 - 4 days per week.

      Taken on an empty stomach because it's and amino acid. Lots of water, some sea salt or trace minerals and vitamin C as well.

      If you have never tried it, start out with 300 mg and work your way up slowly.
