- Caffeine is present in coffee, tea and colas as well in many diet preparations including Hydroxycut, Dexatrim and some Nutrisystem products. Caffeine remains the principal ingredient of most energy drinks and may be purchased in tablet form as NoDoz or Vivarin. Caffeine is even present in Excedrin and other pain relievers.
More than 80% of adults consume caffeine on a daily basis with domestic intake ranking well behind that of Norway, Finland and the United Kingdom. Americans average approximately 200 mg daily with suggested upper limits of 400 mg for healthy adults and 200 mg for pregnant women with much smaller amounts for children and adolescents.
Coffee contains more than 1000 different chemicals including some that provide antioxidant, anti-inflammatory and anti-cancer activities. Surveying the risks and benefits, it seems coffee offers significant potential for improving health.
Caffeine improves alertness, mood and focus. It assists in memory consolidation, decreases drowsiness, aids in coordination and reduces mistakes among shift workers. Studies demonstrate coffee may reduce the rate of cognitive decline in seniors and lower the rate of stroke, heart disease, diabetes, cirrhosis and Parkinson’s Disease. Caffeine appears to reduce the incidence of cancers of the prostate, colon, liver and uterus.
Additional benefits include protection against kidney stones and cataracts. Caffeine improves the overall sense of well being and lowers the likelihood of premature death.
Some experience toxicity including headache, nausea, loss of appetite, restlessness and excessive gastrointestinal motility. Caffeine may induce jitteriness, disturb sleep and lead to anxiety or panic attacks. It rarely leads to elevated blood pressure of cardiac arrhythmias but may predispose to bone loss in susceptible individuals.
Sensitivity to side effects depends on genetic factors involving liver metabolizing enzymes and variations in the genes responsible for the adenosine receptor - the target of caffeine. A typical cup of coffee contains 50-200 mg of caffeine with energy drinks and some Starbucks fare ranging between 200-400 mg. Substantial toxicity develops with more than 1000 mg and fatalities are expected with 10,000 mg or just one tablespoon on powdered product.
This guy is a living encyclopedia!
Sadly he is no more
@@kapilgidwani4735 for real :(
@@simon7789_ yeah...for real. Such a pity. The guy had a great delivery. Not many are doing this kind of commentary at this level.
Repent!
@@kapilgidwani4735repent!
Uhh, mildly addictive? Funniest line of 2024 so far.
Excellent video as always. Especially appreciate the no drama adult delivery. Thank you.
It is always a pleasure to watch and listen to your shows. It’s so fascinating that you remember all those information. Thanks!
Agreed
This Doctor has a brilliant memory for pharmacological information 👏. I appreciate him.... Brother James 🙏🦉
He's reading notes obviously.
No@@anunpopularstance
@@anunpopularstance Yeah for sure LOL...he did add a bit on the fly and he did research his topics pretty thoroughly. It's all in the delivery and he did that really well.
The absolute best medical advice presentations. All his videos are direct and to the point. Love this type of presentation direct and to the point. Thank you doctor.
This guy is sharp.
I quit caffeine 25 years ago because dr told me it increased stomach acid..... thanks dr L
I’m already hyper, caffein makes me worst
This seems to be true. I could drink multiple pots of coffee/day in my teens and 20s, but now in my early 30s, I don't seem to tolerate it as well. A cup or two is OK, anything more and I get very uneasy. As with all stimulants, I believe that the most 'proper use' of this stuff (if that exists) is to use it 'as needed' and not everyday. This keeps the withdrawal/addictive aspect low and keeps it's actual benefits WORKING, ref: 9:47. It is really interesting how he discusses how caffeine makes Tylenol/Motrin work better (eg, Excedrin). Stimulants seem to help pain relief. I went a few months without caffeine a few years ago, and when I had a Starbucks coffee one morning, my heart was pounding out of my chest. It was incredible how much it affected me! In general, I am much better and calmer when limiting caffeine - the therapeutic window, so to speak, is small, for me anyway.
Dr what an honor to have this talks keep it going
wow That was a fun half hour.. while drinking a coffee.
Amazing information!
The fact that sir u spoken all these knowledge and data base just out of your thoughts , are have a gift.
I think he is probably reading something
Most of the studies listed here are just bullshit. Coffee and caffeine beverages is a huge business and it's difficult to know what's true and false. What we know for sure is that everytime you drink a coffee your cortisol and adrenaline levels go up... Caffein destroy your sleep, this is why you can't wake up and function if you don't have your coffee... Caffein is just masking how tired you really are. It also screws your natural digestion rythm.. Ask you just one question: can you function without caffein? If the answer is no that's a pb
Thanks for making these videos, Dr. Landow. I love watching these. They are to the point and very informative!
Thank you for doing these videos, they provide so much value. I would be interested in a video on ADHD, autism, and CBD
Doctor, Please do a video on THC marijuana.
Ur a BRAINEY AMERICAN.
What??
Wow- These videos are absolutely amazing! Thanks for your time Dr..
I'am just binge watching videos by this doctor.Amazing content !
Thank you again Doctor.
I love coffee...I drink way too much of it. I always worry my bones will turn to dust LOL
You sir are living encyclopedia.
100% BRILLIANT
I’ve always had an interest in the effects. I’m unsure but I believe I don’t tolerate it too well if consumed after about midday. I’m trying to lower my intake to see if I’ll sleep better/easier.
Such a great presentation. 35 minutes, 1 take, 0 slip ups. Surely a lecturer also?
You Will sleep better without caffeine
Chamomile & catnip tea are helpful
Could you make a video about cocaine?
Or the Coke in Coca Cola before
Cocaine is still a schedule two narcotic. We used to use it in medications in a compounding pharmacy I worked at. Pharmaceutical grade methamphetamine is also still used as an antidepressant and ADHD medication. These would both be interesting topics!
Ken Landow 2020 Streak: “and you really don’t have to look any further than the white house to see the effects of caffeine on someone with impaired judgment”
Dylan N Some have speculated the president suffers from ulcerative colitis, for which a proton pump inhibitor such as protonix may be prescribed.
He didn't really say that did he?
If sleepy Joe gets elected he better have a 24 hour IV caffeine drip to get him to string a sentence together.
@@Meeshrick Nah, Caffeine isn't nearly strong enough for Joe, He's got to be getting at least 50 mg of adderall XR every 45 minutes.
@@Meeshrick And his handlers probably give him a sort of crack to help amp him up before he gets on stage.
Great video, thank you again.
Thank you doctor!
I really enjoy your information 😊thank you
Thank you. I enjoy your show
Why have you stopped making videos.
Please make more videos doc I love watching these🙂🙂
He passed away a few years ago.
He passed in Vegas back in 2022 I think...
I rather keep it safe an just Macha green tea..or just tea at home. I like the smell..but just a little bit..of caffeine really rarely..
Hello, I've been a nicotine user most my life. I'm 56 now and use the nicorette mints. Am pretty sure the drug is having less than desirable effects on my health. Can't wait to hear some of the facts of this very addictive drug. I never did smoke.
These videos are outstanding. Would love one on nicotine (but excluding cigarettes etc.), just nicotine (taken as a gum for example)
Sounds line caffeine is the new wonder drug.
You sure you didn't forget to disclose that the coffee industry is a sponsors of this video? LOL
Caffeine makes me sweat🙄
85% of people are addicted to caffeine? #22 of world in consumption.
i am a fan
I use caffeine for detrimental low Blood pressure. But organic though. No more than two or 3 third only if it is warranted or medically needed.
Flavonoids & antioxidants are heat sensitive and destroyed by solvents & freezing
The 3 main methods used to process coffee beans
Therefore any benefits associated with these is not present in commercial coffee
Who funded those studies related to reduction of chronic diseases & death rates due to caffeine?
It’s a Big money business
I have yet to see an intake form or a clinician that asks about coffee intake
Commercial coffee is an irritant to the uterus , the heart , the stomach and the nervous system leading to insomnia & agitation
None the less a very interesting video
@@Cbd_7ohm correct some are. However they are up to 80% destroyed by heat. Think roasting coffee beans
Over 400 000 cups of coffee are drunk daily in America
So that tells you that there is lots of money being invested into medical studies that ‘prove’ coffee is healthful
Fake news as Trump would say
@@Cbd_7ohm have you developed any tolerance over time (Ie needing more to get the same result?
I know it’s effective for pain relief and steady energy
@@Cbd_7ohm very interesting. I wondered if the colors were relative to the geographic locations the plants were grown
How does the curing affect color. Isn’t the herb rack dried them ground into powders only?
The people I know who take Kratom buy from someone they found on IG and use as a powder. I think the herb is wild crafted. Wild crafted tends to be richer in beneficial nutrients than hot house grown across the board
Nature knows best
I asked the same question I asked of you. They told me they take 6 days. Rest 1. Then repeat. Have same day off each week
And assure me this keeps tolerance to a minimum
I take moringa and ashwaghanda powders in yoghurt warm water and honey each morning
Great for nutrition and nerves
@@Cbd_7ohm and the process (& therefore K color) that has most nutrition value remaining after processing is.....,,,I’m guessing green
If this is accurate then the other ‘colors’ are created for marketing purposes?
@@Cbd_7ohm Thankyou very much for sharing your knowledge
Caffeine is neat, but calculating its impact on sleep and thus circadian rhythms is just too much of work.
X2 speed makes it perfect
you must be drinking caffeine!
Coffee inhibits the production of collagen? Have I heard that right?
Hey doc, ask your video person to NOT use auto-focus. Put it on manual and focus on your eyes, not the books in the back.
U need MEDS
tuforu4
WTF are you on?
Is there an alternative to taking viagara? I have the worst headache after taking it . Tried lowering dose but still doesn’t agree with me.

Well, one year later, caffeine is now being added to water. 😑

Repent and believe the gospel. Jesus Christ is the way! Believe in Jesus Christ. Not fortune!
