STACKER 2 (100 капс.)
What Is Stacker 2 Fat Burner?
Stacker 2 is advertised as “the world’s strongest fat burner." It may help boost energy, curb cravings, burn fat, and aid weight loss in combination with a balanced diet and exercise.
More than two decades ago, this product was made in the USA by a New Jersey company NVE Pharmaceuticals.
It’s been wildly popular, probably because it’s been endorsed by celebrities, ubiquitously advertised on social media, in magazines, and elsewhere.
The original product formula contained ephedra. According to a study published on PubMed, the use of ephedra in supplements has been banned by the FDA [1]. This is why the Stacker 2 formula has been changed over time.
Although Stacker 2 is now ephedra-free, made with herbal ingredients, easy to get, and affordable, it still doesn’t mean it’s a completely safe and effective energy supplement.
Let’s take a closer look at the key active ingredients of this supplement, their good and bad sides, and whether they can verify the manufacturer’s claims with their effects.

What Are the Ingredients in Stacker 2?
The active ingredients in Stacker 2 are caffeine, yerba mate, kola nuts, Cassia mimosoides extract, white willow bark, green tea leaves, guggulsterone, and Gymnema sylvestre leaves.
Let's take a look at each of their benefits.
Caffeine Anhydrous (200mg)
This potent stimulant mimics the neurotransmitter adenosine to help improve mental alertness and exercise performance. According to several studies published on PubMed, it may provide an energy boost, reduce hunger and fatigue, and trigger thermogenesis to burn fat and stimulate weight loss [2] [3].
From my own use of Stacker 2, I found that while significant weight loss wasn't immediate, there was a notable increase in my focus and alertness throughout the day. This was akin to the effects I've felt from energy drinks or caffeine pills, a sentiment echoed in many online reviews.
Experts also say caffeine may be hazardous in this highly concentrated powdered form [4] [5].
Proprietary Blend (267mg)
Yerba Mate (Leaves)
Apart from being rich in vitamins, minerals, antioxidants, and amino acids, Yerba Mate is another stimulant containing caffeine believed to improve mood and satiety or reduce tiredness [6].
When paired with exercise, Yerba Mate can have the potential to increase your metabolism and calorie burn, but there isn’t enough research to support these claims [7] [8].
Most of my clients say that Stacker 2 works great for an afternoon pick-me-up, but not for longer sustained energy for workouts.
Kola Nuts (Seeds)
Primarily working as a central nervous system (CNS) stimulant, kola nuts are commonly used as additives in sodas, energy drinks, and performance enhancers like fat burners.
It contains large amounts of caffeine and theobromine, which act as stimulants to increase energy and reduce hunger. However, limited studies confirm this effect on humans.
Cassia Mimosoides Extract
Cassia Mimosoides Extract might support weight loss in some people by preventing the absorption of dietary fat in the intestines and promoting their excretion.
Yet, according to a WebMD article, there isn’t enough reliable evidence to confirm its safety and effectiveness, especially when its dose is hidden behind proprietary blends [9].
White Willow Bark
White willow bark has natural anti-inflammatory, antioxidant, and analgesic effects like Aspirin.
Although its tannins and flavonoids may benefit your health, white willow bark is a blood thinner that might damage your liver and brain. Plus, no human studies can directly prove its benefits [10].
Our dietician highlights that it’s best to choose a fat burner that contains scientifically proven ingredients for a more effective and safer weight loss.
