What each ingredient in Romeé is, how much of it is in the can, and the source behind every definition.
A stimulant found naturally in coffee beans, tea leaves and other plants. For most healthy adults, the FDA cites up to 400 mg a day as an amount not generally associated with negative effects.
In Romeé: 85 mg in Matcha Focus, 100 mg in Strawberry Hydrate, 125 mg in Citrus Recharge, 150 mg in Berry Energy.
Caffeine from a plant grown and handled under organic rules. It is the same molecule as synthetic caffeine. The difference is the source and how it is farmed.
In Romeé: All four flavors.
A coffee bean before roasting. “Caffeine from green coffee bean” is caffeine extracted from those raw beans.
In Romeé: The caffeine source in Citrus Recharge, Berry Energy and Strawberry Hydrate.
Green tea from plants shaded as they grow, then ground whole into a fine powder. Shading increases the leaf’s L-theanine and caffeine, and with matcha you consume the whole leaf rather than an infusion.
In Romeé: Organic matcha in Matcha Focus, whose caffeine comes from organic green tea.
A concentrate made from the leaves of the tea plant, Camellia sinensis.
In Romeé: Citrus Recharge and Berry Energy, where the label lists it as the source of L-theanine.
An amino acid found naturally in tea leaves. It is often studied alongside caffeine: a 2014 review of 11 trials found moderate, short-term improvements in alertness and attention switching for the pair.
In Romeé: Matcha Focus, Citrus Recharge and Berry Energy. Not in Strawberry Hydrate.
The time it takes your body to clear half of a dose. For caffeine it averages about 5 hours in adults, with a range of roughly 1.5 to 9.5 hours. Smoking shortens it. Oral contraceptives and pregnancy lengthen it.
A B vitamin involved in more than 100 enzyme reactions in the body, mostly related to protein metabolism. Pyridoxine hydrochloride is the form listed on our label.
In Romeé: 1.76 mg per can, 100% of the Daily Value.
Needed for healthy red blood cell formation, DNA synthesis, and the development and function of the central nervous system. Methylcobalamin is one of the two forms of B12 the body uses directly. Other forms, like cyanocobalamin, are converted into them.
In Romeé: 2.4 mcg per can, 100% of the Daily Value.
Folate helps the body make DNA and RNA and process amino acids. Folic acid is the form used in fortified foods and most supplements. L-5-methyltetrahydrofolate, also called 5-MTHF or methylfolate, is another form some supplements use.
In Romeé: 400 mcg DFE per can, 100% of the Daily Value, as calcium L-5-methyltetrahydrofolate.
The unit used for folate on Nutrition Facts labels. It adjusts for how well different forms are absorbed: 1 mcg DFE equals 1 mcg of folate from food, or 0.6 mcg of folic acid from fortified food or a supplement taken with meals.
A B vitamin that acts as a helper for enzymes involved in the metabolism of fatty acids, glucose and amino acids.
In Romeé: 30 mcg per can, 100% of the Daily Value.
A vitamin the body needs to make collagen, L-carnitine and certain neurotransmitters. Acerola is a small, cherry-like fruit; its extract is the source of vitamin C on our label.
In Romeé: 42 mg per can (45% DV) in Citrus Recharge, Matcha Focus and Berry Energy. 43 mg (50% DV) in Strawberry Hydrate.
A mineral that serves as a cofactor in more than 300 enzyme systems in the body, including ones involved in protein synthesis and muscle and nerve function.

A potassium salt of citric acid, commonly used in drinks to balance acidity.
In Romeé: Citrus Recharge and Strawberry Hydrate.
A sweetener from the fruit of Siraitia grosvenorii, also called luo han guo, a plant native to southern China. It is 100 to 250 times sweeter than sugar.
In Romeé: Organic monk fruit extract, in every can.
The sweet compounds in monk fruit. Mogroside V is the main one in monk fruit extract.
A sweet syrup made from the agave plant. It is a sugar, so it counts toward added sugars on the Nutrition Facts label.
In Romeé: Organic agave syrup is the main sweetener in every can. Each can has 4 g of added sugar, 8% of the Daily Value.
Sugars added during processing, packaged as sweeteners, or coming from syrups, honey and concentrated fruit or vegetable juices. The Daily Value is 50 grams, and the Dietary Guidelines for Americans recommend keeping added sugars under 10% of daily calories.
In Romeé: 4 g per can, 8% of the Daily Value. 5 g of total sugar.
The everyday name for sweeteners like sucralose, aspartame and acesulfame potassium, which the FDA regulates as food additives. The FDA lists aspartame and acesulfame potassium at 200 times sweeter than sugar, and sucralose at 600 times.
In Romeé: None.
Sweet compounds from the leaves of Stevia rebaudiana, a plant native to parts of South America. The FDA lists them at 200 to 400 times sweeter than sugar.
In Romeé: None. We use monk fruit instead.
A sugar alcohol found in some monk fruit and stevia blends. The FDA reviewed studies reporting possible cardiovascular effects and said they did not establish a causal link. It continues to monitor the ingredient.
In Romeé: None. Romeé contains no sugar alcohols.
A plant carbohydrate that the FDA recognized as a dietary fiber in 2018.
In Romeé: 1 g of fiber in Matcha Focus, 4% of the Daily Value.

The acid that makes lemons and limes taste tart. In drinks it adds brightness.
In Romeé: Every flavor.
Reference amounts of nutrients to consume, or not to exceed, each day. The % DV shows how much one serving contributes. The FDA’s rule of thumb: 5% DV or less is low, 20% DV or more is high.
Short for “generally recognized as safe,” a category in US food law. Companies can notify the FDA of their conclusion that an ingredient is GRAS for a specific use, and the FDA can respond that it has no questions.
“100 percent organic” means all ingredients are organic. “Organic” means at least 95% organic ingredients, and “made with organic” at least 70%, not counting water and salt. An asterisk beside a single ingredient marks that ingredient as organic.
In Romeé: Organic ingredients are marked with an asterisk on every ingredient list.
The FDA hasn’t formally defined it. Its long-standing policy is that nothing artificial or synthetic has been added that wouldn’t normally be expected in the food.
A regulated nutrient content claim. The FDA’s updated rule from December 2024 requires food-group content plus limits on added sugars, saturated fat and sodium.
A marketing word with no federal definition. The useful test is whether you can check every line of the label: caffeine in milligrams, named sweeteners, and amounts for the ingredients that matter.
