Caffeine content in raw materials is 0.8–2.5% in coffee beans, up to 5% in tea leaves, about 1.5–2% in mate, and 3.5–5% in guarana seeds.
„Coffee beans contain 0.8–2.5% caffeine. The leaves of Camellia theifera Griff (Thea sinensis L.), from the Theaceae family, contain up to 5% caffeine, also known as theine. The leaves of Ilex paraguariensis A.St.-Hil. (mate, or yerba mate), from the Aquifoliaceae family, contain about 1.5–2% caffeine, about 12% chlorogenic acid, and up to 16% catechins. The seeds of Paullinia cupana Kunth. (guarana), from the Sapindaceae family, contain 3.5–5% caffeine.”W nasionach kawy jest jej od 0,8 do 2,5%. W liściach herbaty Camellia theifera Griff (Thea sinensis L.), z rodziny Theaceae, znajduje sie nawet do 5% kofeiny = teiny. W liściach Ilex paraguariensis A.St.-Hil. = Mate (yerba mate) z rodziny Aquifoliaceae jest ok. 1,5-2% kofeiny, ok. 12% kwasu chlorogenowego oraz do 16% katechin. Paullinia cupana Kunth. – guarana z rodziny Sapindaceae w nasionach zawiera 3,5-5% kofeiny.

The listed figures for raw materials give caffeine content of 1–1.2% in mate, 1–5% in tea, and 0.3–0.5% in cocoa.

Cassine gogonha Raben., Cassine gouguba Guib., Chomelia amara Vell., Ilex mate St.Hil., Ilex paraguayensis St.-Hil.), or mate, the Paraguayan holly: 1–1.2% caffeine; it is used to make yerba mate. My analyses of Pipore, La Merced, and Yerba mate Colon found 1.4–1.6% caffeine.
6. Thea chinensis, Sims (Camellia theifera Griffith, Camellia Thea Link, Thea sinensis), from the Theaceae family, or Chinese tea: 1–5% caffeine (my analyses found 1.3–1.4% caffeine, also known as theine, in Madras and Ceylon black tea).
7. Theobroma cacao L. (Sterculiaceae) (syn. Theobroma leiocarpum Bernoulli, Theobroma pentagonum Bernoulli, Theobroma sativa (Aublet) Lign., Le Bey.), or cocoa, cacao, the cacao tree: 1–4% theobromine (1.66% on average), and 0.3–0.5% caffeine (up to 0.77% in my analyses).”Ilex paraguariensis A.

We selected 1 studies with the best, positive results. This is a selection, not a full review of all research.
Total number of studies on this topic in PubMed: 2 637.
The study estimated that U.S. residents consume an average of 165 mg of caffeine per day from beverages, with coffee as the main source.
Aim of the study: Caffeine is one of the most researched food components, with the vast majority of dietary contributions coming from beverage consumption; however, there is little population-level data on caffeine intakes in the U.S. This study estimated the caffeine intakes of the U.S.
Results: Carbonated soft drinks and tea provided a greater percentage of caffeine in the younger (<18 years) age groups. The percentage of energy drink consumers across all age groups was low (≤10%). These data provide a current perspective on caffeinated beverage consumption patterns and caffeine intakes in the U.S. population.

„Hidden Sources of Stimulation Modern supplement and beverage formulations are often contaminated with stimulants—caffeine or analogs—under names unfamiliar to consumers. Emergen-C now sells an "Energy+" version with added caffeine, and even non-coffee Starbucks drinks often contain stimulants [10]. Meanwhile, OTC sleep aids may combine melatonin with valerian or other sedatives, adding to the neurochemical chaos. Recreational exposure to THC, MDMA, or fentanyl derivatives further complicates biochemical balance.”Hidden Sources of Stimulation Modern supplement and beverage formulations are often contaminated with stimulants-caffeine or analogs-under names unfamiliar to consumers.

„But not one of the 15 supposedly harmful supplement ingredients listed in the Consumer Reports article was a vitamin.[2] Or a probiotic. Why does CBS even mention them? CBS quotes the deputy content editor at Consumer Reports: "Unlike drug products that must be proven safe and effective, dietary supplements do not have to go through FDA approval." But that's not a true statement either. If prescription drugs "must be proven safe and effective," why are so many people dying?”But not one of the 15 supposedly harmful supplement ingredients listed in the Consumer Reports article was a vitamin.[2] Or a probiotic.
