Primary Information, Benefits, Effects, and Important Facts

Caffeine comes from coffee beans, but it can also be synthesized in a laboratory. It has the same structure whether it’s in coffee, energy drinks, tea or pills.

Caffeine is a powerful stimulant, and it can be used to improve physical strength and endurance. It is classified as a nootropic because it sensitizes neurons and provides mental stimulation.

Habitual caffeine use is also associated with a reduced risk of Alzheimer's, cirrhosis, and liver cancer.

Caffeine’s main mechanism concerns antagonizing adenosine receptors. Adenosine causes sedation and relaxation when it acts upon its receptors, located in the brain. Caffeine prevents this action and causes alertness and wakefulness. This inhibition of adenosine can influence the dopamine, serotonin, acetylcholine, and adrenaline systems.

Habitual caffeine use leads to tolerance. This means the effects of caffeine will be diminished, often to the point where the only benefit a user experiences is caffeine’s anti-sleep effect. This is an ‘insurmountable’ tolerance, which means more caffeine will not overcome it. A month-long break from caffeine will reduce tolerance.

Things to Note

Caffeine is a potent stimulant and typically used as a standard due to its social renown.Metabolic effects of caffeine may vary depending on whether one is 'naive' to caffeine (infrequent user) or 'accustomed' to caffeine (daily user)Metabolic effects may also vary due to genetics, specifically a polymorphism on the CYP1A1/2 enzyme[1]One review notes that, after looking at the differences in metabolism between humans and rats, that a 10mg/kg bodyweight dose in rats is roughly bioequivalent to 250mg in a 70kg person.[2]Caffeine can be affected by some prescription medications such as Fluvoxamine and aromatase inhibitors like Anastrozole

How to Take

Recommended dosage, active amounts, other details

Caffeine dosages should be tailored to individuals. If you are new to caffeine supplements, start with a 100mg dose. Typically, 200mg of caffeine is used for fat-burning supplementation, while acute strength increases occur at higher doses, 500mg and above. Researchers tend to use a dosage range of 4-6mg/kg bodyweight. Caffeine can be supplemented through popular beverages, like coffee, tea and energy drinks, but it can also be taken in a pill form. Many of caffeine’s effects, including fat burning, strength benefits, and euphoria, are subject to tolerance, and may not occur in people used to caffeine, no matter how large the dose is.

A: For healthy adults, up to 400 mg/day is considered safe. Pregnant or breastfeeding women are advised to consume no more than 200 mg/day. People with cardiovascular health issues should also consider limiting their caffeine intake.

Q: Do I need to cycle caffeine?

A: There are benefits associated with chronic caffeine consumption, and there are benefits associated with acute caffeine consumption that fade with tolerance; if you like the latter, cycling is mandatory. If you like the former, cycling is not needed

Q: Does caffeine counteract creatine?
A: There is very little evidence that caffeine counteracts the benefits of creatine.

Q: The downsides of caffeine intake
A: Caffeine can have a determinetal impact on your blood pressure, eye pressure, and acid reflux.
