I used NV about a year ago when it was in a different shaped bottle (fatter at the bottom, smaller at the top) and really liked it.

Later, I noticed they changed the look of the box and the shape of the bottle. I didn't think anything of it and bought another one anyway. I didn't like it as well.

Then I read the bottle and it no longer has the vitamins for hair, skin, and nails! I was very disappointed that the formula had changed. I liked it WAY better the way it used to be!

It's more of a beauty pill for me...my nails get stronger, and hair grows quickly and with shine. My skin is clear and radiant and my skin gets softer. I basically take it to look good, although my intentsions were to loose weight!

The only thing I notice is that it doesn't curb my appetite, I still get hungry. It gives me a lot of energy, although I recommend taking it early during the day as taking it later might cut your sleep.

I love it! It gives me the energy I need during the day, I don't get sleepy; it makes me look very pretty... the best beauty pill! :-)

I tried NV and felt tired, starved, jittery, with a lot of anxiety, with some nausea and vomiting.

At first I thought I was pregnant so I stopped taking it after 2 months knowing that I was not pregnant during the process.

After I stopped I felt normal and to my luck I did not lose a pound, but gained 10.

This is just my story but I think the caffeine content is maybe too high since Im a Starbucks coffee drinker. I stopped drinking it to get the same amount of caffeine I would get from my regular morning drink with this pill. And still made me sick.

The best of luck if you are trying maybe it works for you.

I have been taking NV for about a week. All of a sudden I feel depressed. People have noticed that I am very quiet. Sure, I'm not hungry but by 4pm I am sleepy. I had to FORCE myself to go to the gym and typically I love the gym. Has anyone else had this kind of reaction?

I used NV for 2 months, and lost roughly 40 lbs. I LOVED only having to take ONE pill per day. My appetite was decreased, I always felt full. I was coming off a hip injury which made cardio difficult and painful, so exercise was limited mainly to upper body weight training. Despite my lowered activity levels, the weight still came off. I experienced no side effects while using NV. In short, I am very pleased with this product, and would use it again if necessary.

I started using NV after having a baby last year Sept 07. I stopped cause I crash most of the time when I take it and my mood just drives me nuts.

But I love the energy that it gives me and I'm thinking of going back to it.....

I have actually been taking NV for about a Month now and I absolutely love it.

I have already lost 11 pounds and I do see a difference in my hair and nails. When I first bought NV I was like "here is just another diet pill that im wasting money on and it will do nothing for me."

Now a month later and it proved me wrong -- it has worked wonders for me! I feel awake and not so hungry any more. I work in an office where I sit all day long and when I got bored I would find something to eat. With NV I dont get hungry and I'm not falling asleep by 2 anymore - I'm still awake and ready to go! I LOVE IT!

NV has worked for me after I had my baby I lost 20 lbs. using these diet pills. They are very easy to take -- they don't make me feel sick and definitely decrease my appetite.

Now I'm off to Cancun for spring break and I just bought my second bottle of NV.

Been taking NV for 3 days. I don't see an increase in energy, nor any weight loss. Basically, I find its not working, I have enough pills for 6 more days.

I am wondering if taking a different diet pill will work. Currently I'm a 140lbs and would like to loose 12 lbs. by April 3rd as I am going south to the Caribbean.

Editor's note: Three days of taking NV is not really a fair assessment. Although the best diet pills can be helpful, it is important to have a realistic expectation of the sort results you will see with any diet product.

I've been taking NV for about a year now.

I loved how much energy it gave me for my daily work out. I only wanted to lose about 10lbs and and lost 15. My stomach has stayed flat and and the rest of my body tight and firm.

I never saw a difference in my hair and nails, but I strongly support this pill.

It is only my first day using NV and so far, so good!

I am a new mother and depended on sugary sodas for an energy boost, and I am so happy that this has enough energy that I will not need soda anymore (though I wonder if sleep will come tonight because I feel so energized. Does anyone know if you can use OTC sleep aids with this?)

My appetite is suppressed and I have the motivation & energy to work out. My wedding is in 6 weeks so I'm hoping to lose 15 lbs.

I started taking NV about 1 month ago. I really only take it Monday through Friday because it is in my desk drawer at work.

I was drawn to the product mostly due to the vitamin supplements (b vitamins usually help metabolism and increase energy) as well as the additional weight loss help. I've noticed that I am not as hungry at lunch or dinner, however I've also started drinking a lot more water which may have been my issue with the weight in the first place.

My nails are longer and stronger and I no longer have the mid-afternoon slump at work when I take a pill prior to lunch.

I've also gotten to the point that if I forget to take a pill at lunch, then I take one when I feel sluggish in the afternoon. For that alone, I'm willing to continue to use it.

Only started taking NV 2 days ago, but I do have extra energy and it does help to suppress my appetite. I've lost 4lbs in a week but I've been doing Slim Fast w/ NV so I'm not sure which it was...

So far I am loving this product. I'm 16, and a model. I've only been using NV for a few days and my appetite is already decreasing. Now it is way easier to get in shape! I looove it =]

I love this product. It is not exactly a fat burner, but more of an appetite suppressant. I have noticed that I do not eat as large or meals and my snacking has lessened while taking NV. Also, my nails have become stronger, and my hair appears shinier. NV is not a magic pill, but if you are taking it while watching your intake and exercising, it can be that last thing needed to help with the appetite!

I HAVE tried NV. I had fantastic results for the first 2-3 weeks. Each week I was losing anywhere from 5-8 lbs, my hair was shiny and my skin was radiant. Then I noticed that it no longer had the same effect it did. I was tired all the time and I gained all the weight back. My skin and hair still look nice though :)

So, I guess it sort of helps. But you really have to listen to your body. In the first 2 weeks, I stopped when I was full. After the 3rd week, I didn't really feel full any longer.
