N-Acetyl L-Cysteine (NAC) Powder

Key Features

  • Supports liver function
  • More bioavailable form of L-Cysteine
  • 100% pure
  • Taste

  • Mixability

N-Acetyl L-Cysteine (NAC) is a type of amino acid that is sulfur based and is needed in order for the synthesis of Glutathione to take place. Since Glutathione is a powerful antioxidant, this makes the presence of N-Acetyl L-Cysteine all the more important.


Serving Size & Timing

It is suggested that N-Acetyl L-Cysteine be taken in serving sizes of 600mg (scant 1/4 tsp) up to three times per day. It is also recommended that, if possible, the supplement be taken with Vitamin B6, Vitamin E and Selenium in order to enhance the antioxidant properties of it. Vitamin C supplements, if taken in conjunction with NAC, can also assist the antioxidant abilities while increasing the amount of glutathione being produced by the body.

This N-Acetyl L-Cysteine supplement is considered pharmaceutical grade and has no fillers of any kind present in it.


As long as suggested serving sizes are adhered to, this product is considered safe. However, if you are taking nitroglycerin or any medications that affect the heart, a medical professional should be consulted beforehand. It is also possible that NAC may block insulin, which means that diabetics are cautioned from taking this supplement.

If taking more than the recommended amount, side effects such as vomiting, nausea, headache and gastrointestinal pains may be experienced from use of this supplement. However, these side effects are quite rare. Taking a larger amount of one supplement may cause the absorption of other supplements to be less effective; it is important to supplement other minerals such as copper and zinc to make up for what is being lost.


This product is water soluble and has a bit of a sour flavor. It can be mixed with either water or juice. If the sourness of the supplement is too much to handle, it may be purchased in capsule form. Of the many forms of Cysteine, N-Acetyl L-Cysteine is easily the most bioavailable. It should be stored in an area that is free from light, heat and moisture.


Due to varying import regulations, not all of our supplements are available to international customers. This product is restricted for sale in the following countries:

Customer Reviews

I have asthma and this helps with suppressing immune inflammatory responses to allergic reactions. It helps relax my lungs and makes me use my inhaler less.*

On 10/1/2016 Christopher said...

After reading all of the above testimonials it is hard to add anything, but my reason for using NAC is for the broad spectrum benefits such as the antioxidant benefits, the production of GSH & the possibility of it's role in destroying H-pylori. Am hoping it will benefit my husband's shortness of breath. The potentials are numerous.
Another great product & service from Bulk Supplements.*

On 9/24/2016 Selena said...

Awesome Product
I loved this stuff so much that I bought 2 kgs of this product. I've found nothing that even comes close to it when it comes to its antioxidant benefits and its liver support capabilities. And the pricing and service from bulk supplements is like no other! highly recommended!

Side tip: this stuff comes in quite handy when you're drinking to prevent hangovers. Just take a serving before heading to bed along with adequate water. *

On 9/19/2016 Sujayram said...

NAC works
I am impressed with the apparent benefit I receive from this product in improved breathing and other effects. I enjoy being able to set and monitor my dose, filling veggie capsules or mixing in a smoothie is the best way to go.*

On 9/17/2016 Suzan said...

Best Product
Again we used Bulk Supp's NAC and have had a amazing results and will be a customer for life like many of the other products they have that deliver at a great price. *

On 8/24/2016 James said...

Two parts here:

One, excellent quality, low cost, reasonable shipping on smaller orders, with no BS loyalty credits or other hoops to jump through. That is for everything I've ordered here. This may sound like a broken record (you are young enough to get the metaphor, remember LPs?) but it is a pleasant contrast with the sheer amount of hype one encounters when seeking out good supplements elsewhere.

Two: NAC being a precursor for glutiothione is what some (many?) EMSs give for certain oxaditive stress related emergencies; and is an important part of any pre-emptive health regimen. Use the interwebs.*

I feel this product is worth using as a traumatic brain injury survivor.*

I feel healthier while taking it, and it adds energy to my workouts. This is a very potent product. You may want to add some favoring before consuming. Overall, I'm very happy with the purchase and will be buying more when that time comes.*

First Time using NAC
After reading about this supplement as a powerful anti-oxidant with a wide range of benefits, I decided to give it a try. It does have an odor and is tart, but it is not a big deal. I mixed mine with a little juice and it is easy to take. *

On 3/29/2016 Kimberly said...

I really enjoy the product & for the benefits it delivers. I see that you have the NAC in a lot of different quantities. I have found that your company has many of the products that I was searching for. The prices are great & for shipping, it is extremely fast. I will certainly buy again.*

On 3/19/2016 George said...

NAC/ Great value
I am well versed on the health benefits of NAC. I have been purchasing this in capsule form from NOW supplements. That is until I found the same thing in bulk form at

I purchase 500g of this product from them and am thrilled at the quality and the amount of money I saved. I am and will be a customer moving forward.*

On 3/9/2016 sean said...

NAC powder
Great product, when I reorder I will probably try the capsules. It mixes good in water, has a little bit of a scent to it. It is another great product from bulksupplements. This by far the most pure form of nac I have taken.*

On 2/23/2016 John said...

Best deal on NAC
I wish I began my use of NAC by ordering from Bulk Supplements. Just as they state the product easily mixes in water and a scant 1/4 teaspoon equals 600 milligrams. I find that the Ziploc package in which they send it is the most convenient way to use and store it. I was vaguely aware that NAC has a strong scent, but I never opened the capsules from another supplier that I had started out with. It is obvious upon opening the packet from Bulk Supplements that it is pure. My order from Bulk Supplements arrived right on schedule. To me, this is the only way to go for NAC.*

On 2/16/2016 Timothy said...

NAC works for my family
I had done some research on natural treatments for breathing problems and sleep apnea. I've started giving this to my children 4, 7 and 9 in 600 mg doses twice a day. My four year old was just diagnosed with asthma which only appears at night and seems to become aggravated when he has a viral infection. My 9 year old appears to have sleep apnea possibly from swollen turbinates and a deviated septum. Their may be an issue with something in our house and we're moving soon. After 3 days of giving them the NAC, they, especially the 4 year old, are breathing much better at night. I use this with ginger and turmeric for inflammation, ALA, vitamin D. Research this before you give this to your own children, but we have had no negative side effects. And this beats having to resort to albuterol or the like. I love that this product is pure and arrives in a timely manner.*

On 1/26/2016 Belinda said...

NAC is a very valuable addition to your dietary regime
NAC is essential in creating gluthathione and great for aiding the other antioxidants in your diet. I take mine with equal amounts of vitamin c and this world well for me. As usual, Bulk Supplements delivers quickly and provides the purest products available.*

On 1/17/2016 robert said...

I am switching over to B.S. NAC from another brand in capsule form. I have been switching to B.S. over time with any supplement that they stock that I use and I have never been disappointed. Most of the time I feel that B.S. is a superior product to what I have been taking. I feel this is the case with this NAC. Using B.S. high quality products has become my new benchmark for quality. Taking other brands with all the fillers just doesn't make sense to me anymore, plus the fact that using B.S. is less expensive makes it a no brainer. I take NAC for general health maintenance - to boost and maintain glutathione " the master antioxidant " levels. Customer service with this company has always been outstanding.*

N - Acetyl - Cysteine powder
Not only does NAC promote glutathione production (the body's major anti-oxidant), it has now been shown to activate the human telomerase gene, which is known as the fountain of youth gene. Great price for a supplement that virtually everyone should be taking.*

On 10/26/2015 Donald said...

In my research of NAC, here are a few things I found out . NAC Is the dietary supplement of choice for building up cysteine or conserving the body's store of glutathione . Is a chelator of heavy metals . ( might help people with metal fillings in their teeth .)Is an anti-inflammatory. Smokers should consider taking . Smoke can cause cross linking of DNA . Should be taking with vitamin C . There are many more but that is enough for me .I hope this helps.

N-Acetyl L-Cysteine (NAC) is a go to supplement for me, It is so important in managing inflammation and overall metabolic function. Of course I but from Bulk Supplements for not only the great price but the excellent quality and customer service.*

On 10/12/2015 Brett said...

Brett harsha
N-acetyl L-cysteine is a must have for me. it plays such a huge role in combating inflammation and providing overall metabolic health. However it is one of the more expensive supplements at the store and as it grew in popularity so did the price. as with many other supplements. If people think a supplement fights fat for instance, there goes the price through the roof. Take CLA for example. That is why i am so glad I found bulk supplements, they have great quality supplements and customer service you can't beat all for a low price. *

On 10/12/2015 Brett said...

Very potent and pure
This is a potent and very pure form of NAC that I have yet to come across in other brands. Will be coming back for more in addition to other complimentary supplements for glutathione synthesis. *

N-Acetyl L-Cysteine
The is a powerful antioxidant SOD/Glutathione inducing pro-drug that puts my arthritis into remission and quenches the chest pains that I've had for years, resulting from 3 different heart surgeries. This form of NAC seems to have great bioavailability, unlike others forms, and many other antioxidant concoctions.*

On 8/18/2015 JW said...

Best NAC Product
After doing DNA testing and seeing the recommended results from Nutrahacker for supplementation, I decided to add NAC and DIM. The NAC I got previously was good I suppose, really couldn't tell a difference in how I felt, but the NAC from Bulk Supplements was different. In just a few days, it seemed my fibromyalgia pain has lessened considerably. I hope this is the case. I am very impressed with the staff and customer service at Bulk Supplements and will continue to order from them. *

The NAC for training
As an old gym rat I love N-acetyl-L-cysteine for getting rid of soreness. I initially took it just for the free radical scavenger effect. While taking it in combination with L- glutamine I discovered it was almost impossible to make myself sore. I have even tried to produce soreness while taking this and failed. I hear young guys say they like soreness because it shows them they worked out hard. This old man knows he works out hard and like the fact that N-acetyl-L-cysteine helps him not move like an old man. *

N-Acetyl l-cysteine has stopped me from getting colds after running five fifty-second sprints three times weekly.
First I want to say that this n-acetyl l-cysteine (NAC) is rated US Pharmaceutical grade, a very high grade of purity, according to the BulkSupplements website. This US-based purity test assures that even if this n-acetyl l-cysteine is manufactured in China that purity problems of any kind should be extremely unlikely.

I run five fifty-second sprints in the mornings. Over the past year I have gotten bad colds lasting over two weeks several times. I figured it was due to exercising too hard. I have progressively cut back from eight fifty-second sprints seven days a week to five fifty-second sprints three days a week. But even breathing through my nose the entire time while running I was still getting colds. For the last six months, I have been taking 0.6 grams of n-acetyl-l-cysteine three times a day, which has knocked out the colds and stopped most of the coughing and sniffling at the ends of the runs as well.

The following is a list of clinical trials, most double-blinded and placebo-controlled, recorded at the National Medical Library, MEDLINE, as abstracted by GreenMedInfo for n-Acetyl l-cysteine:

25. A nutrient combination [Acetyl-l-carnitine, Alpha-Lipoic Acid, Fish Oil, Ginkgo biloba, Huperzine, Multivitamin, NAC (N-acetyl-L-cysteine), and Vinpocetine] improves cognitive function in head-injured former NFL players.

I take many different supps, some for working out, most for health. Even though I take a few different antioxidents, I wanted to add NAC for the express purpose of helping glutethione synthesis. Probably won't feel a whole lot, but if there are no side effects, I'll keep it in my regime. I do order about 5 different supps from Bulk Supps and have no problems.*

N-Acetyl L-Cysteine (NAC) is very Potent
I am not someone who is quick to give credit to any particular supplement because I drain myself in vitamins and minerals thereby making sure that I get all the 90 Essential nutrients necessary for good health.

I have gotten a very tremendous benefit with applying NAC topically to my razor bumps on my scalp. I have been dealing with these razor bumps for almost 15 years. When I started applying NAC to these bumps, most of these bumps disapperared within one week. For the first time since I had this condition, I can confidently tell you that I am almost healed of this unsightly skin condition.

I thank God for Bulk Supplement's NAC product.*

This is very easy to ingest and the price is amazing! This is definitely the place to go for any type of supplements. *
