Best Supplement for Headache: Jarrow Formulas N-A-C 500 mg - Antioxidant Amino Acid Supplement â€" Supports Cellular Health & Liver Function - Precursor to Glutathione - Up to 60 Servings (Veggie Caps) (Packaging May Vary)

I am guessing I was pretty toxic and probably with good reason

This supplement is truly a life changer. I wish I had started sooner but I didn't really understand all the benefits. First couple of days, I got a little Headache and there was nothing left in my intestines....plus some serious gas. I am guessing I was pretty toxic and probably with good reason. However, after a couple of weeks, I feel great. It is very calming as I do not have the anxiety I used to have all the time. Secondly, I have a lot less issues with cravings and have been losing weight. I feel like I have better control over my thoughts and feel more positive and clear headed...better thinking and processing of information. I have been sleeping better as well. Sometimes, I even have a little coffee in the afternoon and it does not make me all sweaty and shaky. Honestly, I am 50 and have not felt so good in a long time. I feel like I can better handle stressful situations and don't feel so helpless when I get into a situation that used to shut me down emotionally. I know it is the NAC because it is the only item I have added to my supplement regimen. Thank goodness for NAC!!! As a side note, this formula is fantastic. I have tried other supplements containing NAC and they stink like Sulphur...and you taste that grossness for a long time after taking. Not this formula...it has a slight smell but you do not notice anything unpleasant after taking it. So glad I found this on Amazon and thank you Jarrow. Please do not ever stop selling this stuff...it is a miracle in a bottle

Changed My Life.

My Headache specialist recommended N-A-C Sustain to me for daily energy and to help me combat the effects of pressure fronts. I'm really glad that he did! Within a few days I started to notice a marked increase in energy in the mornings and after a week or so I stopped noticing the pressure changes. Used to be I couldn't enjoy the sound of rain because of my headaches but now I sure can! I've been using N-A-C for about a year now and I doubt I'll ever stop. I take one in the morning when I get up and one at night before I go to bed each day. This has made a huge difference in my life and I highly recommend it to anyone who suffers negative effects from weather changes or feel like they have low energy

Helps with nasal allergies.

I like this product, and am glad that Jarrow makes it. It helps with my allergies, which can be severe. When the pollen is severe, and I'm totally stuffed up, NAC can help open up my breathing by thinning my mucus. The regular kind (non-sustained-release) doesn't work very well for me; I get little effect from it. But for some reason the Jarrow time release formula does. While it does work, and I've been grateful for having it around several times, it can have side effects. Some people have reported feelings of Headache or mild nausea if they take it on an empty stomach. My experience has been that it works best if you take it with an equal amount of vitamin C (to detoxify it). I've sometimes felt a little ill after taking it. So in that sense, taking it can feel more like taking an over the counter medicine than a supplement.' Also if you take it, be aware that NAC is a natural chelator, meaning it will remove minerals from your body... both the bad ones like mercury and the good ones like calcium and magnesium. So I recommend taking a good mineral supplement if you use it frequently. Oh, and, NAC works best if you take it with a lot of water

Before taking this I used to get horrible hangovers. I would wake up with a terrible Headache and almost flu like body aches. If I take this with my first drink I now wake up feeling dried out but it is nothing a gatorade can't take care of. In other words my hangovers decreased from a level 7 (ugh my day is wasted and I don't want to leave the couch) to a 2 (breakfast and hydration will fix me up pretty well)

Was skeptical but saw results.

Started 600 mg the first day, was told by my doctor that it wouldn't have noticeable results for a few months, but unbeknownst to me I had a small amount of fluid in my lungs and coughed it up on the first day. I've been on it about a month now and per Dr.â€˜s orders will be doubling my dose. I've been taking it with juice first thing in the morning, I did notice I had a slight stomach ache and slight Headache but that has gone away now. I can't wait to see what 1200 mg does

Think it's working! Because of the headaches…

I truly hope the initial reactions of my body improve, but so far it sounds like it's working in me. I'll also mention it wasn't the only change so it could be the Headache was from the Numedica HM Protect instead (this is to detox what that released). I can only assume with a non-time release version my reactions would only have been worse. Do yourself a favor and look up NAC and where our hospitals (yes, actual MD's) use it to prevent damage from things like contrast dyes and other known toxins. Take some when you go out drinking at a minimum to prevent some of the hangover the next day. I'm sadly tee-totaling it lately, but I can use all the help I can get with getting back to healthy
