Does the self-proclaimed smallest pill on the market produce big results?

Top Rated Diet Pills of 2016
BACKGROUND BACKGROUND Start the Diet Now Advertisement

nanoSLIM is a one-per-day diet supplement that claims to be the smallest pill on the market. The active ingredient in nanoSLIM is corosolic acid, which maintains healthy glucose levels in the body to aid weight loss. nanoSLIM gives your cells more energy, and this allows glucose to move into your muscle tissue to convert to energy instead of fat.

The key ingredients are all plant-based - lagerstroemia speciosa L. (crape-myrtle leaves), cha' de bugre extract (a Brazilian tree), green coffee extract and thallus powder (twigs). There is a long list of other ingredients including Blue No. 2, maltodextrin (a potato starch commonly used as a water soluble glue), carmine (Red No. 4) and stearic acid (a common saturated fat).

nanoSLIM discusses the importance of diet and exercise when losing weight. The site describes an eight-week study to learn nanoSLIM's results and explained that exercise and a healthy diet were required for all participants. During those two months, participants were able to lose an average of 10.6 pounds.

Like the many other diet supplements, nanoSLIM does not provide enough relevant information. Rather, it repeats the few facts they choose to present. The product FAQ only has five questions, none of which provide great detail. While nanoSLIM promotes diet and exercise to achieve the desired results, it offers no guidance in these areas.

  • Limited information
  • No explicit diet or exercise guidance
  • Does not appear to be 100% organic ingredients
  • May contain wheat
Diet and NutritionDiet and Nutrition



nanoSLIM does recommend you commit to regular exercise while using the diet pill. However, there is not any specific guidance supplied.


There are so many diet pills and supplements available that it's important to weed out the one that is best for you. nanoSLIM offers a lot of incomplete and vague product information, making it difficult to accurately access its value. nanoSLIM does not make any all-natural claims and there are plenty of those supplements available. It's important to do research and consult your physician before beginning a new diet regimen.

Usually I get horrible side effects from diet pills. You know the kind that make you feel irratible, you have to use the bathroom what seems like every ten-minutes, your gag reflex feels funny, and you can't fall alsleep at night. Nano Slim didn't do that to me, but all of the others did. I drank a lof of diet coke with the Nano Slim, now that caused the side effects. I just started taking it, so I haven't seen results yet. I chose nano slim, because I can't swallow pills. The powder packetts for slim quick, and hydroxycut might mess with my gastritis, so I should stay away from those. Those work, but they have side effects. So, so far if you are looking for a pill that is easy to swallow (the size of a birth control pill) without side effects this one is for you. I bought mine on clearance for a little over six dollars at wal-greens. They don't have it anymore, and I don't know where to find it.

I'm coming to the end of a box of nanoSLIM and it has done absolutely nothing for me. I started a calorie reduced diet on the day I began taking them and I lost the standard water weight, that you would lose on any diet, but that's it. I even had the stomach flu for four days, and STILL barely lost an ounce.
The only good thing I can say about nanoSLIM is that I felt no side affects.

I'm currently using Nano Slim. I've been using for two weeks combining with my own diet, (eating less) and biking on my exercise bike for 30 min everyday, I also added some light weight and crunches twice a week. I've notice my face is less round and I've lost some weight on my belly, I'm not obese, far away from that I was just not very happy about my body. In Sept 07 my weight was 119 pounds and I jumped to 132, my goal is to come back to 119. I can tell NanoSlim is helping this process. I'm drinking lots of water too at least 2 Litres a day (68 ounces) I've heard you need lots of water with this product

Today I went to walgreens to see what diet pill i could find to give me that extra boost I need to start losing weight. I tried other diet pills but they make me feel crazy and I can't sleep. I also tried SLIM30 and lost about 25lb but once my body got use to the product I stop losing the weight. I havent been taking anything for about a year and I've gained all my weight back and more.I am currently 162lbs. I'm only 5'4 so the weight makes me feel sad. I talked to the manager at the store today and she recommended I try nanoSLIM, she said that her husband has been using it and has lost about 10lb after about a month in a half. My goal is to lose about 25-30lbs so I hope this works along with my daily excersizing and diet change. I'll post a note in a couple of weeks to let everyone know if I've lost any weight.

Hello all, havent been on in a while so i wanted to update all of you. I've been taking nanoslim for a month now and along with diet and exercise have lost 22 lbs. Hopefully I can achieve my target goal of 35 lbs in 8 weeks. I'm on track so far and with continued hard work I should be able to achieve it. Sept. 15 is my deadline date. Good luck to all of you,so far so good for me. No noticeable side affects besides having to urinate often, which is ok with me,cleans out the system.

I took nanoslim for several months and noticed about a 5 pound weight loss. I do exercise daily and closely watch what I eat too. The weight loss wasn't major, but it was easy to take one pill and I didn't notice any side effects or jittery feelings. I stopped taking it 2 weeks ago and have since gained 5 lbs. I still exercise and watch my diet, so maybe I should go back on it!

Sorry about the delay. I'm a little mixed about reporting back because I'm embarassed to say that I've been taking nanoslim and I'm a guy. In my defense, no where on the box did it , indicate that nanoslim was for woman only. It's not until you open the box and read the pamphlet that the first sentence references woman. However, I did read some articles and it seems as though most Dr's think it's ok for men to use it. Anyways, as I said I would report back every week. I had my first official weigh in on Monday and as it turns out I lost 7.2lbs. I did find myself urinating a little more than usual but I believe nanoslim is a diuretic which helps clean out your system. The negative is that I did find myself not being able to get a good nits sleep

Okay, I bought Nanoslim the other day and tried it... the first day, I've been urinating like crazy! my boyfriend thought i was going wacko... AND, I've been hungry all that day... I will log on again to check up on other comments after I take the next few ones...

I'll start my treatment tomorrow...Hopefully It will work out!! Good luck to everyone, and keep us posted!

Hello everyone: I read ALL comments on here and the one thing that comes to mind is "individual results may vary". Certainly no weight loss pill can give you the will to motivate yourself to lose weight. The common denominator with all dietary supplements includes a healthy diet and exercise plan . I'm no gym buff, I'm not a nutrionalists and I definitely don't work for nanoslim but I'd like to think I've done a good job losing weight. I'm 31 years old and prior to this year, never took being overweight seriously enough to do something about it. I've been fortunate enough not to have any health issues, instead I simply decided I was tired of being overweight. I'm 5' 9" and at my max weighed 305lbs. With only diet and exercise I was able to lose 57lbs in only 3 months, that's not bragging hopefully that inspires someone to know that it can be done. Inspiration was huge for me when I first started. Anyways, after a 5 week hiatus from my diet and exercise I haven't gained any weight but as I'm sure you've guessed I haven't lost any. As of today 07/14 I'm officially re-starting my diet and exercise plan along with what I hope is beneficial aid from nanoslim. Like many of you I've never taken a diet pill but chose nanoslim based on its comparison to other top brand diet pills but mostly because of the convenience of taking one tiny pill a day. I also wanted to do something to spark my metabolism again and do a comparison to see what I can achieve this time with a little help. My new plan spans an 8 week time frame with tomorrow being the first time I take nanoslim (figure morning works best). I'll check back every Monday night with updates on progress, possible side effects and hopefully good news (just not as long, lol). Guess I'll be one of the guinea pigs for this pill. Best of luck to everyone, losing weight and maintaining it is a life change! Thanks
