The world of energy drinks is vast, and there isn’t enough time to give every drink the full “Energy Drink of the Month” deep dive review. In my attempt to guide my fans through this world of energy drinks, I like to share the science behind the various caffeinated beverages I come across in my travels.
On a request from one of my fans via Instagram, here is the Science Behind Xyience!
Caffeine
Caffeine comes from plain caffeine and from guarana seed extract. There’s 176 mg caffeine per can (88 mg per serving and 2 servings per container). According to Caffeine Informer, Xyience used to be 200 mg per can. Either way, it’s Fatigue Level 3.
Key Ingredients
This drink contains B-vitamins, and some stereotypical energy drink ingredients including guarana, glucuronolactone, taurine, ginseng root extract, and inositol.
- Glucuronolactone might feed one reaction that helps the body generate energy, but glucuronolactone has to go through some small transformations first, and this reaction (the Pentose Phosphate Pathway) isn’t a major reaction, energy wise
- Taurine is a taxi cab that helps shuttle water-hating fat molecules to the place they need to be metabolized
- Ginseng is supposed to help with stress but a systematic review of almost 500 studies involving Panax Ginseng found the only benefit was for glucose metabolism in animal models
- Inositol helps with insomnia…(kind of ironic, right?)
- B-Vitamins include 100% of niacin (my favorite vitamin), 250% of B6, 80% of B12, and 500% (why?) of Pantothenic Acid
- Niacin is part of over 200 reactions in the body, most of them involving the production of ENERGY.
- B6 helps our bodies make those non-essential amino acids and also helps us maintain optimal blood sugar levels.
- B12 helps our bodies make healthy red blood cells
- B5 helps with the metabolism of carbs, fat, and protein, but there’s so much of it in every food group no one needs a B5 supplement (in my opinion)
Other Notes
Preservatives in this drink include potassium sorbate, potassium benzoate, and sodium citrate.
- Potassium sorbate – this anti-microbial preservative prevents yeast and mold growth in sodas and other foods. The Center for Science in the Public Interest (CSPI) rates this as safe. If the CSPI, who has a reputation for fear-mongering and chemophobia, rates this safe, you should definitely feel at ease. [See Panera KNOW-No Project Part IV]
- Sodium Benzoate – Did you know that benzoate salts like this one prevent the growth of microorganisms like yeast and mold? Benzoate salts are often used with other preservatives especially at low pH (acidic food). People can ingest up to 5mg per kg of body weight of benzoic acid and its salts according to European Commission – Scientific Committee on Food.
- Sodium Citrate and Citric Acid – both are abundant naturally in citrus fruits and are used in beverages to help control the pH.
Fruit and vegetable juice is used for color, but this drink has artificial sweeteners Ace-K and Sucralose. But there are only 2 grams of carbs (from the juice, most likely) and zero Calories, zero grams of sugar.
