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

Top Rated Diet Pills of 2024
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.

I used to use this product here in Canada in 2008 and 2009! It was wonderful, I had more energy, I was more confidant and I liked the ease next to other pills on the market. There was no side affects I had ie. choking down multiple big pills 3 times a day timing before you ate and the nasty bathroom visits of others I have recently tried! I miss this product here in my local Canadian Wal-Mart, please bring nanoSLIM back to Canada!!!!

For everyone's information, maltodextrin is from corn, not potato. If you are allergic to corn, stay away from this product.

I exercised regularly and tried various diet pills. This was by far my favorite and noticed the most results. Although its been a few years so I don't remember numbers, but I haven't been able to find them since that first pack I bought in like 2010. Are they still available??

Hi you guys! I took NanoSlim for a month and I lost 8 pounds.I didnt even change my diet so much,I just cut out the sweets a bit,but I think that it really works.The only side effect i had was that it made me pee more often and I could hold it for a long time.

nanoslim is a great product, i went from almost 170 pounds to 135 pounds in 2 months, from a size 12 toa size 8. I also did change my diet, stopped drinking pop, and change my eating habits. i only took it for 2 months and have kept the weight off for a yr now, i say put this product back in the stores again. i works awsome
