This is the ingredient list for Monster Energy Drink. The ingredient everyone focuses on is Caffeine. Caffeine is not the only stimulant in the drink. But I'll concentrate on it first. There are 3 servings in a can. The Caffeine level was measured by consumer reports as being 270 mg. per can. There is actually 90 mg. per serving but few people only drink one serving - they drink the whole can.
Still there is more Caffeine in a cup of Starbuck's coffee. What is not in Starbuck's coffee are the other additives.
Next I'll focus on Guarana. Guarana is a natural stimulant. It contains Caffeine and at least 2 other cardiac stimulants. There is debate that Monster does not include the caffeine level in the guarana in the advertized Caffeine level of Monster energy drinks. A representative of the Monster Beverage Corporation provided another reason: The company doesn’t list levels “because there is no legal or commercial business requirement to do so, and also because our products are completely safe, and the actual numbers are not meaningful to most consumers.”
Theobromine and Theophylline are the other 2 cardiac stimulants in the guarana in Monster energy drink.A partial list of the components of guarana seeds. Chemical component Adenine Ash Caffeine Catechutannic-acid Choline D-catechin Fat Guanine Hypoxanthine Mucilage Protein Resin Saponin Starch Tannin Theobromine Theophylline Timbonine
It is recommended that if you drink guarana that you do not drink other caffeine containing beverages.
There are B vitamins in Monster Energy drink. They are a well known source of safe energy.
It also contains Panax Ginseng. Another safe source of energy.
Taurine is an amino acid. It is considered to be a safe source of energy.
L-Carnitine is not much help for energy but it is supposed to help with fat metabolism. L-Carnitine and Taurine may actually have some beneficial health benefits when taken properly.
Glucuronolactone is considered harmless and probably not beneficial as well.
Inositol is a sweetener.
Maltodextrin is a complicated sugar.
Monster Energy does recommend that you drink no more than 2 servings of Monster per day. That is 2/3's of a can. Monster Espresso contains 3 times the caffeine and other ingredient levels that regular monster contains.
