Super Happy with this Supplement!
I have been using NAC consistently for quite a few years and was thrilled to find these by Now brand at 1,000mg. They are a larger, hard pill as opposed to a capsule, but I find them easy to swallow with no aftertaste and no side effects. This is a wonderful supplement with many benefits to be had and I highly recommend them!

No Awful NAC Supplement Smell or Taste!!
My dermatologist recommended NAC to me to help with my trichotillomania (trich) symptoms, but I initially started with 600 mg capsules to gradually work up to the dose they recommended. I barely made it a week and a half with those because the smell and taste were AWFUL. They made me gag every time I tried to take them. I was so happy to find these 1000 mg capsules, especially since I couldn’t find this strength at CVS, Walgreens, or the other stores I checked. These are definitely large capsules, but for me they are SO much easier to take because there is no noticeable odor or taste. I keep them separate from the rest of my medications in my pillbox and take them individually because of the size, but I have no trouble swallowing them that way. I’ve now been taking NAC consistently for about three weeks at the dose recommended by my doctors, and I’ve personally noticed a pretty dramatic reduction in my trich symptoms. Obviously everyone is different, and I would definitely recommend checking with your own doctor about whether NAC is appropriate for you and what dose you should take. I’m just really glad I found a 1000 mg option that I can actually tolerate taking consistently. If your doctor has recommended NAC but you’ve struggled with the smell or taste of other capsules, I would absolutely give this one a try.

Great for ODD (Oppositional Defiance Disorder)!
First let me give you a summary of my 10 year old daughter. She's always been a problem child, literally since day one. For some that may be a hard concept to imagine, but for those who have ever dealt with a child with behavioral/emotional/mental issues I know you guys understand me. She's always struggled in school, at home, in social situations. Comprehension has never come easy to her and getting her to read anything was literally like pulling teeth! She was eventually diagnosed with ODD (Oppositional Defiant Disorder) because her behavior had gotten so bad both at home and in school. She had CPS called out to the home for making bogus statements at home. Life was extremely stressful to say the least. I was at a loss and heartbroken when I was advised that the only thing I could do to "protect" myself and her siblings would be to start calling the cops on her myself and making a police report (yes it got THAT bad). I've tried everything imaginable, every kind of supplement I came across but to no avail. I even gave in to try medicines which helped the mood, but only really seemed to temporarily mask the problem. With the side effects of the medicine already having me feeling on edge, I didn't feel comfortable upping the dosage so we opted to discontinue and seek other treatment. I have researched and researched and finally came across NAC supplement. I read a number of articles and realized that she would be a pretty good candidate to try this. I began giving this to her on the evening of 02.26.16 and the NEXT day she was reading like she had been reading all of her life! I could have cried watching how excited she had become about reading literally OVERNIGHT! Within less than a week she managed to reach her comprehension goals at school and her mood is so much more positive! ***Update 01/2017 - We had a bit of a set back regarding mood issues (I'm thinking due to changes in hormones caused by mensturation) but have since changed up her vitamins with positive results. She is now diagnosed more towards Bipolar and OCD btw. I tried her on St Johns Wort and Lithium Orotate and although I could see a difference it wasn't helping mood and aggitation like I was hoping it would. Plus it seemed to make her OCD behavior worse. I did some research and found that sometimes mood disorders aren't serotonin related (Which most doctors primarily focus on) but dopamine. So we searched for alternatives and found L-Tyrosine. So far I am thrilled. For those interested her daily regime is below. Keep in mind I am not a doctor, just a loving parent who wants to give her child the best chance at life! :) Note, I'm not including dosage because everyone is different so I encourage starting low and working up to the dosages that you find works for you! AM: L-Tyrosine / NAC / Niacinamide PM: NAC / L-Carnatine

Now vitamins rock
These are big pills and I am not a fan of the taste. But they are helping. My doctor told me about NAC for my health issues. Now has been my go to vitamin shop for years. I believe the quality is there and pricing is better than most.

AMAZING FOR COMPULSIVE SKIN PICKING/HAIR PULLING
I’ve struggled with the compulsion to pick at my skin when stressed since I was a child. I’ve seen doctors about this issue with no real results. Compulsive, repetitive body-focused behaviors (skin picking, hair pulling, biting nails) are theorized to thrive in individuals with low-glutamate levels (an amino acid), which makes it harder to control emotions and impulses. I read some scientific research that supplementing with NAC daily (which helps stimulate glutamate production) in people with these behaviors showed that about 60% experienced a MASSIVE reduction in picking, so I decided to try it out. 18 months later, I have gone from often picking uncontrollably to going weeks without picking, only having a few flare ups when I’m extra stressed. I noticed a difference in my picking impulse right away. My skin looks SO much better, and I no longer feel embarrassed to go out without wearing makeup! Along with awareness practices toward the patterns that trigger picking, I can honestly say this supplement has been a GAME CHANGER for me. I take this along with Inositol in the morning. This seems to be the magic combo! Also, if I get an urge to pick in the day, I take 1-2 more NAC pills. I haven’t experienced any side effects. Although it hasn’t completely stopped the picking, I would say I have experienced at least an 80% reduction! If you have struggled with anything like this, I highly recommend trying this supplement along with Inositol! It really helps! For reference, I take daily: 1. ~2,000 MG of NAC 2. 5G of Inositol (start with 2MG and build slowly with this, it can give you gas) 3. 30 MG of Zinc Picolinate with Quercetin (zinc needs a carrier to be absorbed by cells) 4. 100-200MG of High Absorption Magnesium (80% of Americans are deficient in Magnesium, and deficiency can cause debilitating anxiety.) This regime has drastically increased my ability to control impulses/stress levels, AND has reduced my acne (a major trigger for my picking). Hope this may help someone that’s struggling. You’re not alone. <3

Good quality NAC supplement, easy to stick with
I’ve purchased this twice now and have been happy with it. The tablets are a decent size but manageable, and the bottle lasts a long time with 120 tablets. I like that it is a straightforward NAC supplement without a lot of unnecessary extras. I take it as part of my general wellbeing routine and have found it easy to keep consistent with. The packaging was fine, delivery was quick, and the product matched the listing. The only thing I’d mention is that it doesn’t taste the best, so I usually breathe through my nose when taking it. The tablets are also a little large, so that may matter if you struggle swallowing tablets. That said, it’s a small price to pay for a product I’m happy with. Overall, I will be buying it again. Now has been a very strong brand for me and my health.

Made me extremely dizzy
After listening to the Huberman Lab podcast, I purchased a bottle of the supplement. However, after taking one pill, I woke up extremely dizzy. I stopped taking it, and after half a day, I felt fine again. A week later, I tried again, but 8 hours later, I experienced vertigo-like dizziness. I immediately stopped taking it, and it's clear that the supplement is causing this reaction. Unfortunately, I can't return it.
