Stacker4 by Stacker2
Are you not familiar with Stacker4 yet? It is a dietary supplement in capsule form from the Stacker2 brand, a name that has been well-known for years. Each capsule contains caffeine and a fixed mix of herbal extracts. Stacker4 is the ephedra-free successor to the original Stacker formulas and is sold in a bottle of 100 capsules.
What is in Stacker4
The composition of Stacker 4 revolves around two components. The first is caffeine anhydrous, a concentrated form of caffeine in powder form. The second is a herbal mix of green tea extract, yerba mate, guarana, capsicum, kola nut and Siberian ginseng. Caffeine also occurs naturally in coffee beans, tea leaves and guarana seeds. In Stacker4, it is included both as pure caffeine and through those plant-based sources. The capsule itself is made of hypromellose (plant-based). The manufacturer does not disclose the exact dosage per herbal extract, because they are in a fixed mix of 250 milligrams. However, the caffeine content is listed separately, because that is legally required for these types of amounts.
A high dose of caffeine per capsule
What many people want to know about Stacker4 is how much caffeine is in each capsule. The answer: 300 milligrams per capsule. That is a high amount, comparable to about three cups of coffee in a single capsule. Precisely because of that content, it is important to stick to the indicated dosage and not just take multiple capsules at once. People who are sensitive to caffeine will clearly notice such a dose. For comparison: a regular cup of filter coffee contains around 90 milligrams of caffeine. Three capsules a day, the maximum indicated by the manufacturer, therefore come out to 900 milligrams. That is why it is wise to count your own caffeine intake from other sources as well.
The herbal extracts in the blend
In addition to caffeine, Stacker4 contains a blend of plant extracts. Green tea and yerba mate are leaves that have traditionally been brewed as tea. Guarana is a seed from the Amazon that naturally contains caffeine. Capsicum is the substance from Spanish pepper that provides the spicy taste. Kola nut comes from the kola nut tree and Siberian ginseng is a root, not to be confused with the Panax ginseng you find in other supplements. Green tea and guarana naturally provide part of the caffeine content, while capsicum is known for the spicy substance capsaicin. The extracts are combined into a fixed mix, so that every capsule contains the same ratio.
Ephedra-free for years
The original Stacker products used to contain ephedra. That substance is no longer allowed in supplements in Europe. Stacker 4 is therefore formulated completely without ephedra, with caffeine and herbal extracts as the base. The product is marketed in Europe by Stacker2 Europe and is one of the best-known names in its category. The capsule form makes it easy to dose, without having to weigh or mix anything. Good to know: because EU legislation is strict about what you may say about the effects of such a product, you will mainly find information about the composition and use on this page.
