We’ve sampled our products at hundreds of events and we’ve noticed a clear pattern regarding the use of caffeine in America.
Most people fall into one of three categories with regard to caffeine tolerance:
Hyper-Caffeine Aware: Probably one in every five people we speak with is nervous to try even a one ounce sample of a drink with caffeine in it any time after the morning. The caffeine hits them and it hits them hard, they say. These are the folks who are maybe only drinking tea on a daily basis.
Aware of Caffeine, but Not Worried About It: This person we see most frequently. They don’t want to down a cup of coffee in the afternoon, but aren’t super cautious about their caffeine consumption outside of that.
Don’t Know, Don’t Care: These people feel like the caffeine doesn’t impact them. Perhaps they’ve had enough coffee in their life time that their body is metabolizing it differently. Perhaps it never affected them much at all. They are nearly superhuman in their consumption habits … and they are the folks who we’re talking about today.
“Caffeine tolerance”, or more simply, a reduced sensitivity to the effects of caffeine, can develop in folks who consume caffeine regularly … and in some cases, aggressively. Over time, the body becomes accustomed to the presence of caffeine, leading to a decreased response to its stimulant properties.
But if you’re wondering, “why doesn’t caffeine affect me?” - read on and learn how your body work.
How Caffeine Affects the Body
When caffeine enters the body, the liver produces enzymes, primarily cytochrome P450 1A2, responsible for metabolizing caffeine. With regular caffeine consumption, the activity of these enzymes may increase, leading to faster caffeine metabolism and reduced effects.
The body gets smarter and smarter and adapts if you keep presenting it the same information. It’s like the original AI. BodyGPT. And it’s not just the liver that learns and adapts. The brain works in a similar way!
Caffeine binds to adenosine receptors in the brain, which normally promote feelings of drowsiness. With consistent exposure to caffeine, these receptors may become less sensitive to the inputs, meaning they are less responsive to the presence of adenosine or substances like caffeine that bind to those receptors.
And adenosine receptors aren’t just caffeine hubs. They are responsible for regulating various physiological processes in the body that adenosine plays a role in, including sleep-wake cycles and the release of certain neurotransmitters.
Unfortunately, this can lead to a variety of negative effects.
When adenosine receptors are less sensitive or downregulated, their ability to inhibit neurotransmitters like dopamine and norepinephrine is diminished. As a result, individuals may experience reduced sedation and feel less drowsy even without consuming caffeine. Less drowsy or sedated feelings may feel good sometimes, but it can wreak havoc on one’s ability to fall asleep regularly.
Adenosine is also involved in regulating the immune response and has anti-inflammatory properties. It can reduce inflammation by binding to specific adenosine receptors and modulating the release of inflammatory mediators.
If adenosine receptors are downregulated, the anti-inflammatory response may be weakened, potentially leading to a less effective immune response.
Caffeine and the Central Nervous System
Since caffeine can influence the release of various neurotransmitters, including dopamine, serotonin, and norepinephrine, the CNS may decrease the release of certain neurotransmitters in response to caffeine's stimulatory effects to maintain balance. If the brain is sensing there’s too much dopamine is being released too regularly, it’s going to work to alter its response to your next dose of caffeine.
For the central nervous system, the goal is basically to remain calm and at ease. Adjustments in neurotransmitter receptors, release, and sensitivity aim to restore homeostasis in the presence of caffeine and mitigate its stimulating effects.
Those adjustments will be unique to you though. Specific adaptations in the central nervous system depend on factors like your physiology, genetics, and the dosage and how much caffeine you drink and how regularly you drink it.
It's also important to note that although caffeine tolerance can develop, it does not mean that the substance has lost all of its effects. Individuals who have built up tolerance may still experience some of the cognitive and physical effects of caffeine, but to a lesser extent.
Cycling or Detoxing Caffeine
To maintain sensitivity to caffeine, some people choose to reduce or cycle their caffeine intake periodically. For many people this happens after a little thing called college. The all-nighters are done and it's time to join the regular world - coffee is now less of a fuel and more an excuse to take a 15 minute break.
By reducing or eliminating caffeine intake for a period of time, individuals may allow their body to reset its tolerance. This approach, known as a "caffeine detox" or "caffeine reset," gives the body a chance to restore its sensitivity to caffeine over time. Withdrawal symptoms may be experienced initially, but they typically subside within a few days.
For others, instead of completely eliminating caffeine, they choose to cycle their caffeine intake. This involves periodically taking breaks from caffeine consumption, such as abstaining for a few days or weeks, to prevent or reduce tolerance buildup. By spacing out periods of caffeine use, it may be possible to maintain a more consistent sensitivity to its effects.
Ultimately, your caffeine tolerance will depend on your body. At some level, your liver and brain will adapt to the caffeine invasion, metabolizing it faster and making you less sensitive to its energizing effects. The brain's adenosine receptors, which normally make you feel sleepy, start shrugging off caffeine like it's no big deal.
This can impact your sleep and immune response and your central nervous system will try to keep the peace by adjusting neurotransmitter release and sensitivity.
But hey, tolerance doesn't mean caffeine loses all its powers. You'll still feel some effects, just not as strong.
If you want to regain your caffeine sensitivity, you can try a caffeine detox and give your body a break. Or you can play it cool and cycle your caffeine intake, taking breaks here and there. So, if you want that extra kick from your cup of caffeine, remember to give your body a chance to reset!
I love making the cacao latte over ice on a warm day and just started making it hot. It tastes great and isn’t as sugary as a typical hot cocoa drink. I also love all the great healthy ingredients it has that I don’t get in other types of drinks.
I absolutely love this product. It's great on it's own; however, I add it to my one cup of coffee each morning. It has balanced out my body and definitely helped me perform better each day. After I began using it actually helped balance my digestion as I was having some trouble and it has helped with my weight as I'm dealing with menopause which isn't that fun! lol. This is an outstanding product that I have had great success with. Highly recommend.
I’m a fan, this has become my goto afternoon pick me up
I love getting an energy boost naturally! With a shot of local honey!🐝
I am an avid coffee drinker. I never read the directions; I dump a full scoop of CacoaLatte in my cup and fill it with seven ounces of smoking hot coffee from our super fancy coffee machine at work (we use premium beans).
WOW, that makes for a great afternoon, HELLO!
I typically take calls after or zoon through the meeting feeling great without feeling overly tweaked by the coffee jolt. I also enjoy the natural flavor because I can't stand artificial sweeteners in anything.
Dump in the cup, add 7 oz of premium Joe, and life gets GOOD!
