What is Stacker 3?

Stacker 3 is an energizing supplement with expensive ingredients (from South America) containing herbal ingredients, which help users lose weight and improve metabolism while reducing fat. The main ingredients that could have some impact on weight are green tea leaf (caffeine), garcinia cambogia and chitosan, but just how much impact science isn’t exactly sure about.

  • Clinical Nutrition – The total amount of green tea in Stacker 3 is not revealed, but we know it’s less than 325mg, because that’s the entire amount in the proprietary blend that contains the green tea. Some research has shown therapeutic effects of green tea only at high doses of 850mg or more daily.
  • World Journal of Gastroenterology – There’s tons of research on garcinia, but unfortunately, much of it pertains to negative reactions and side effects.
  • Medicina – “Based on the meta-analysis realized with 14 RCT we concluded that the usage of chitosan as a dietary supplement can lead to a slight short- and medium-term effect on weight loss and to the improvement of serum lipid profile and cardiovascular factors.”

Research published in the Journal of Clinical Biochemistry and Nutrition found that garcinia had no significant health benefits on the body. Another study published in the International Journal of Obesity and Related Metabolic Disorders noted that chitosan had no effect on body weight.

What Users Are Saying

What Users Are Saying

“Very good product, I used as directed and get a nice energy boost! Also takes away my appetite after eating a healthy meal. I’m already seeing steady results I would highly recommend for anyone with a HIGH CAFFEINE tolerance like me.”

“Ordered 2 bottles of these and they didn’t do a thing! Coffee gives me more energy then these. NOT the same as they were.”

“Use this for energy, and take 2 each morning.. It does help if I take it right away in the morning but if I wait to take it I’m exhausted until I do. Works well if you add it as a solid morning routine. Avoid taking it with 4 hours of going to bed or you will be awake until 5am. Some people use it for weight loss I guess but being a fire performer who also chases around my 4 year old all day I am pretty much always hungry and this doesn’t suppress my appetite at all which in my case is a good thing. Recommend for a little extra energy in the morning!”

Bottom Line

The Bottom Line on Stacker 3

So, will you lose weight with Stacker 3? Well, we like the longevity of the company and the inclusion of a few natural ingredients, but we have reservations about it because of the lack of published clinical research connecting it to weight-loss. We’re also concerned about the side effects and lack of results mentioned in customer reviews.

You’ve reached the point where you want to lose weight, but you’ve tried time and again only to regain the weight. Not this time – with a weight-loss app that’s supported by doctors, healthcare providers and hospitals, we’ve got an answer you may have overlooked.

Of all the weight-loss apps on the market, the one that sets the bar higher than the rest is Noom. As soon as an extensive, human clinical trial was completed and showed increased weight loss and improve weight maintenance when using Noom we knew we were behind this app all the way.

  • Some Peoples May be Allergic
    Tiffany (Verified Purchase)

    Stackers are awesome!! Some people may be allergic to them and that is unfortunate, but still not a reason to not recommend them because obviously not everyone is going to have an allergic reaction. And the two MAIN things you need to know before taking this product is to drink plenty of water and get moving!!! Do not take this and then sit around all day because it will make you feel crappy. If you are up and moving you feel just fine! Love it love it love it (:

    • Your Name

      Did you lose weight?

  • Didn't loose weight but gained much energy
    Jonathan (Verified Purchase)

    I first used Stacker 3 for weight loss, and I did not notice any weight loss, but I did get a lot of energy. I now use it to pull al nighters for school. I think it really helps. I also lose the hunger for like 2-4 hours and then I get very hungry afterwards. I am just very satisfied with the amount of energy it gives me to stay awake and alert, and to workout even longer and more intensive. I think this may be better than the 5 Hour Power Energy shot.

  • little extra energy
    Lindsey (Verified Purchase)

    I take Stacker 3 to help increase the results of exercise and to get a little extra energy. If I take it without eating about 20 mins after I do get jittery, but if I do something active like a workout or cleaning the house or playing with the kids I do not get jittery. I like them just for the extra energy but apparently have not taken them long enough (less than 1 week) to see weight loss results. Overall, thumbs up!
