Scientists have discovered that caffeine doesn’t just perk up your brain—it energizes your cells in a way that could slow aging.
By flipping on an ancient fuel-sensing enzyme called AMPK, caffeine indirectly taps into a powerful longevity pathway that helps cells manage stress, repair damage, and live longer.
Caffeine’s Cellular Anti-Aging Mystery Uncovered
A new study from the Cellular Ageing and Senescence laboratory at Queen Mary University of London’s Center for Molecular Cell Biology reveals how caffeine—the world’s most popular neuroactive compound—might do more than just wake you up. The study in the journal Microbial Cell shows how caffeine could play a role in slowing down the aging process at a cellular level.
Caffeine has long been linked to potential health benefits, including reduced risk of age-related diseases. But how it works inside our cells, and what exactly are its connections with nutrient and stress responsive gene and protein networks has remained a mystery—until now.
In new research published by scientists studying fission yeast—a single-celled organism surprisingly similar to human cells—researchers found that caffeine affects aging by tapping into an ancient cellular energy system.
Fission yeast is also known as “mini-human” due to its similarities with human cells.
A few years ago, the same research team found that caffeine helps cells live longer by acting on a growth regulator called TOR (Target of Rapamycin). TOR is a biological switch that tells cells when to grow, based on how much food and energy is available. This switch has been controlling energy and stress responses in living things for over 500 million years.

Ancient Energy Switches: TOR & AMPK
But in their latest study, the scientists made a surprising discovery: caffeine doesn’t act on this growth switch directly. Instead, it works by activating another important system called AMPK, a cellular fuel gauge that is evolutionarily conserved in yeast and humans.
AMPK (AMP-activated protein kinase), is a cellular energy sensor that plays a vital role in maintaining metabolic balance. Indirect inhibition of AMPK, through the widely used anti-diabetic drug metformin, has already attracted attention for its beneficial effects.
“When your cells are low on energy, AMPK kicks in to help them cope,” explains Dr. Charalampos (Babis) Rallis, Reader in Genetics, Genomics and Fundamental Cell Biology at Queen Mary University of London, the study’s senior author. “And our results show that caffeine helps flip that switch.”
Interestingly, AMPK is also the target of metformin, a common diabetes drug that’s being studied for its potential to extend human lifespan together with rapamycin.

Metformin Links and DNA Repair Boosts
Using their yeast model, the researchers showed that caffeine’s effect on AMPK influences how cells grow, repair their DNA, and respond to stress—all of which are tied to aging and disease.
“These findings help explain why caffeine might be beneficial for health and longevity,” said Dr. John-Patrick Alao the postdoctoral research scientist leading this study. “And they open up exciting possibilities for future research into how we might trigger these effects more directly—with diet, lifestyle, or new medicines.”

Arabica beans, regardless of brand................
I love my Kona Coffee, all day long!
Yes a few of them
Remember you get to do 89 twice. You do not get to do 26 again.
I was being sarcastic about International House. 😎😂🕺
Last Wednesday my Doctor told me to switch to decaffeinated coffee. He said I am “overstimulated.”
How can you call that stuff “coffee” if it doesn’t contain coffee?
I thought it was real, there are so many brands................

All those studies involve large doses. Moderation is the key.
There are lots of great health benefits.
Notably it has neuroprotective features, preventing both Parkinson’s and Alzheimer’s and helps grow new blood vessels (which is why tumors like it, too, sadly).
Not really. It just sounds better. It’s a coffee alternative.
That little animated mushroom in the Ryze ads is really cute; I usually hate animation.

I hadn’t seen that. I just checked it out. Yes, it’s cute.

What I should say is that some mushroom coffees DO have coffee. But then you aren’t switching from coffee to an alternative. It depends what kind of product you are purchasing.
I drink 3-4 diet sun drops a day for 500mg
Then 3-4 Milo’s low calorie tea for 200mg
Then 2-3 diet dr peppers for another 100-150mg
Pretty high
My oldest son consumes 1500 likely
He sweats a lot lol
Btw you get used to caffeine pretty much except very high doses which can make you sick
“Notably it has neuroprotective features, preventing both Parkinson’s and Alzheimer’s and helps grow new blood vessels (which is why tumors like it, too, sadly).”
Everyone knows how just about all pilots on all sides in WW2 smoked. It was to steady their nerves and help concentration as they flew over targets and engaged enemy warplanes. During the C19 panic some said smoking protected them against the virus and the vaccinations. All anecdotal, not the kind of thing that anyone would pay for, to conduct a scientific study.
Actually, lots of studies have been paid for:

Notably nicotine it has neuroprotective features, preventing both Parkinson’s and Alzheimer’s and helps grow new blood vessels

While nicotine is predominantly associated with health risks, research indicates it may have specific neuroprotective and angiogenic properties under controlled conditions.
However, these potential benefits are heavily outweighed by its well-documented harms, including cancer progression and addiction. Below is a detailed analysis:
Neuroprotective Effects
Parkinson’s disease: Epidemiologic studies show smokers have a 30–50% lower risk of developing Parkinson’s. Nicotine appears to protect dopaminergic neurons by:
Activating α4β2 nicotinic receptors, enhancing dopamine release and reducing neuroinflammation.
Inhibiting mitochondrial dysfunction and oxidative stress.
Limitation: These findings derive from animal models and observational human studies; no clinical trials confirm therapeutic efficacy.
Alzheimer’s disease: Nicotine may temporarily improve attention and memory by:
Binding to hippocampal and cortical nicotinic receptors, boosting acetylcholine signaling.
Reducing β-amyloid plaque accumulation in preclinical studies.
Limitation: Human trials (e.g., transdermal nicotine patches) show minimal long-term cognitive benefits and no disease modification.
“Where would Europeans have obtained their caffeine prior to the importation of coffee about five hundred years ago?”
From the Muslim Arabs who got it from Ethiopia. They/Muslim Arabs have been drinking it for 6 centuries ..... I read they also liked it for marathon prayer sessions at night. Not drinking it these days. But in the past I would simmer coffee (Cafe Bustelo brand) the same way they do. And drink it black

Muslim Arabs have been drinking coffee for approximately six centuries—since the mid-15th century—with the earliest evidence of coffee roasting and consumption found in Yemen during this period. However, some traditions and legends suggest that certain Muslim figures (such as the 8th-century Yemeni saint Sheikh Jaabir al-Bakri) may have discovered or used coffee beans even earlier, but these accounts are less verifiable and more legendary.
Coffee was introduced to Arabia from Africa—specifically, from Ethiopia. Somali merchants from Berbera and Zeila transported coffee beans from the Ethiopian regions of Harar and Kaffa to Yemen, where it was cultivated and popularized. By the 15th century, coffee was well established in Yemen and soon spread throughout the Middle East, becoming a staple of Arab and Islamic culture.
Summary:
Muslim Arabs have been drinking coffee for about 550–600 years, with the drink arriving in Yemen from Ethiopia via Somali traders in the late medieval period. The beverage then became central to social and religious life across the Arab world.
