Stacker 3 Video Review

Overview

What is Stacker 3?

Stacker 3 is a dietary supplement by NVE Pharmaceuticals, marketed as a fat burner and energizer. Available at retailers like Amazon, CVS, and Walmart, it targets those seeking help in weight management. Its key ingredients include green tea leaf extract, providing caffeine; Garcinia Cambogia, a tropical fruit; and Chitosan, a fiber from shellfish. While these ingredients are common in weight loss supplements, their effectiveness varies and isn’t conclusively proven. Stacker 3 is ephedra-free, addressing safety concerns associated with the substance. Users are advised to consult healthcare professionals before starting the supplement, particularly if they have health conditions or are on other medications. The product claims to boost metabolism and energy, but effectiveness may vary among individuals.

  • Clinical Nutrition – The total amount of green tea in Stacker 3 is not revealed, but we know it’s less than 305mg, 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.”

Lawsuits

Stacker 3 Lawsuits

NVE Pharmaceuticals filed for chapter 11 bankruptcy in U.S. Bankruptcy Court, District of New Jersey, on Aug. 10 because Stacker 3 is under pressure from numerous lawsuits. In 2004, the state of New Jersey filed a lawsuit against NVE, alleging the company advertised its ephedra-based products as safe despite receiving hundreds of complaints from consumers who experienced adverse effects from the supplements.

What Users Are Saying

What Users Are Saying

“Cheap & effective – I use 2 of these a day gives me all day energy no need for coffee or energy drinks any more.”

“I love these. They don’t make me jittery, but everyone is different. They are good for appetite suppression and energy.”

“These are not regulated. Can take up to 3 daily with sometimes no effects, but then take one & heart rate is at 140 – causes extreme nausea, diarrhea, and anal leakage (get wipes) lost 2 pounds in a month, though that could be water weight – and because of extreme symptoms, got hardly anything accomplished during this month. Total waste of time and money. Disappointed is an understatement.”

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.

      Please ask your doctor to look over the formula for you. What may be most affected with taking a diet supplement is possible reduction of your birth control’s efficacy.

    Back when I was in High school I was about 250 pounds. I was tired of being the biggest kid in my class and a friend recommended me to use stackers. I started them in May of 2009 and by September I dropped down to 170 pounds. I worked out for a hour daily, cut fast food, pop and candy and I was amazed at the results I got. I just started back taking them after a weight gain I experienced in college after fracturing my knee and I’m hoping for the same outcome!

    On Jan 1st I weighed 220. Two years ago and with the help of a six month prescription of diet med I went from 260 to 220 but had stayed at 220 for almost a year. I started Stacker 3 in Jan and today 9/8 I am 174. It increases the metabolism, makes you less hungry, and I have had 0 side effects with the exception of some mild high blood pressure. Hard to tell if it’s related or not because it’s always been slightly elevated. This loss is without hardly any physical exercise. I walk occasionally, do some stretches, some yoga stuff here and there (beginner’s stuff) so in my opinion it works. The year prior I ttoj a number if over the counter stuff that has zero impact. I’m a male, 53 years old

    I had one for my very first time. Made sure I had a good breakfast and had enough water with it. I work fast food so I wanted a little boost in the morning. An hour later I started having some really uncontrollable shaking throughout my whole body, very rapid heartbeat, dizziness. I couldn’t even hold anything in my hands, it was hard to stand as if my knees were bubbling and weakening at the same time. I was sweating all over everywhere and could barely hold a conversation. (I had to leave work) Wasn’t emotionally stable and had to get taken to the ER. NEVER trying again.

    My friend has been doing stacker 3 for 18 months now and has lost 60 lbs. I myself have been using it for just a little while and have had no side affects and some weight lose. I feel it works for some people who have the metabolism that works with it.
    Everyone is different. I maintain a ridged diet and exercise program and do not eat sweets or eat out. If you can do this, weight lose will happen. Good luck to all no matter what you take. Just remember it will only work if you can maintain a strong conviction to do so properly.

    Thomas Cook (Verified Purchase)

    I used stacker 3 xplc to improve my energy at work. I thought everything was ok at first but after a year of one pill a day it affected my kidneys. I read the label and found meny warnings about my symptoms. I have no family history of kidney stones but I did develop a 13 mm kidney stone during the use of this product. I wish I would have been more aware of what harm stacker products can do yo my body. No stars only pain and regret.

    You have to have food on your stomach, drink plenty of water and liquids, and you have to take it when you are moving around, cooking, cleaning, dancing, working, running, walking just stay busy.. Drink! Drink! Drink! Your urine will let you know if you drinking enough water because if it’s yellow and not almost clear you are not drinking enough water and fluids.

      I used to have a big problem with 3 different types of drugs and thank God I was able to quit before my children came along. I now use stacker 3 XPLC and it makes me feel like I’m back to my old ways. But I take only 2 a day instead of 3 and I feel like I’m back doing what I used to do. I cook, clean, talk alot, and 8 have been asked the same thing by my family, but I went to take a drug test for them and all of them watching so they knew I was telling the truth. Clean as a whistle… but yes it will make her seem as 8f she is back on what she used to be doing. Hope that eases your mind a little bit God bless and may her sobriety Stay strong

  • I needed extra energy
    Jay

    Trying the S3 XPLC, Been on it for less than a week. I have tried S2 before and did not really notice any weight decrease, but no jitter or negative impact on me. I have also tried the prescribed Phentermine, but that gives me bad dreams, and makes me edgy, short tempered so I stoppped it. It does provide great energy but that another story.

    For taking the stackers, if it is your first time around, I do recommend eating first. For this time, I needed extra energy to get pass the afternoons at work, it does provide good energy for about 2-3 hours, but then after you get so hungry. I just supplement it with eating fruits or drinking more water. So far so good. I have 3 of these bottles and hope to help me supplement weightloss plan with my strict diet – no rice & no red meat + more fruits and veggies.

    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 (:

    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!
