What Is Caffeine?
Well, caffeine is a drug, it's a stimulant. It is the most commonly consumed stimulant worldwide. It's a methylxanthine actually. And in its pure form caffeine is a white crystalline powder with a bitter taste. And you can find it in different places in nature. You can find it in coffee beans, in tea leaves, and you can find it in cocoa beans. You can even find it in the flowers of some citrus plants.

Benefits Of Caffeine

What The Science Says
• Caffeine can make you more alert
• Can help with memory
• May help decrease symptoms of depression
• May be beneficial in some long-term neurodegenerative disorders
• Medicinal purposes

Side-Effects of Caffeine
• Restlessness
• Anxiety
• Can worsen high blood pressure
• Jitteriness
• Increased heart rate
• Dehydration


Caffeine Addiction:
You can also develop a tolerance to caffeine, where you need more and more. We believe that 400 milligrams or less has a pretty low potential for causing bad problems. But if you're someone who drinks coffee daily and if you're drinking 400 milligrams or more to get that alertness, focus, or memory sharpness, your body actually may develop a tolerance, in other words, it blocks those adenosine receptors which keeps us awake? Your brain might make even MORE of these receptors!


Caffeine withdrawal can be rough, but there are ways to prevent it. If you're addicted to caffeine and suddenly stop consuming it, then yes that may lead to symptoms of withdrawal like headaches or feeling tired/sluggish throughout the day. But if this is a problem for you then try cutting back gradually instead of just stopping all at once-it'll help lessen those side effects!

Caffeine Withdrawal Symptoms
• Headache
• Fatigue
• Irritability
• Flu-like symptoms
• Struggle to concentration


Is caffeine bad for you?
The general rule is less than 400 milligrams a day for adults, but again, consult your physician. Caffeine is the most widely consumed stimulant in the world. And so this definitely affects a lot of people. We have over 150 million Americans who consume coffee daily. So the next time you pick up your cup of coffee, a cup of tea, or you're grabbing that energy drink, just really be cognizant.

Think about how much caffeine you're taking in and make sure you do things in moderation. And while you're getting those benefits, like being alert being awake, trying not to be sleepy, trying to focus, or to do things in a more efficient way, think about the potentially dangerous effects as well, like developing tolerance or getting withdrawal symptoms or having a fast heart rate, or dehydrating yourself. Everything in life is about balance.

  • I had a kidney transplant 12 years ago. I still drink a cup of coffee in the mornings but I chug water all day every day. Those energy drinks are sooooooooo bad for us. Great video Doc!✌️
  • @SparklingWalrus
    I stopped drinking caffeine and I’ve never felt better. I strongly recommend everyone to stop consuming it. water is all you need.

    You don’t need to consult your physician. If you’re drinking too much caffeine it’s because of your diet. You’re not getting proper nutrition. Work on your health by eating right taking your vitamins and exercising and you’ll feel very little need for caffeine. Thank you dear that was a great video! :-)
  • I was watching another video about coffee but they were taking forever to actually give any information, then I glanced Dr. Frita and I came right to her page cause she does not beat round the bush.
  • Dr. Frita, always looking great. Smart, intelligent and straight to the point. Thank you for being very informative.
  • You're the best doctor in my life and miracles and health thank God for you amen 🙏👍💖

    Great video! Love to see educational videos with facts about this topic as opposed to ulterior motives. Thanks for the great video! Very informative.

    "Everything in life is a balance" Well said! Takes a little time to get that right, though, doesn't it? :))
  • Hi Dr Frieda I love ur Video’s I have kidney disease & I have learned so Much about my illness from you. I praise the Lord for you. TY for making & sharing ur great video’s
  • It is crazy to me that it is so widely consumed for hundreds of years but so few studies! I'm guessing no one has the deep pockets to force Starbucks, McDonalds, Tully's and Dunkin to foot the bill for this since they are the major beneficiaries.
  • As always, very informative. Thank you so much. You continue to be one of my absolute favorites. Obviously beautiful and intelligent, but you carry it in a very humble and helpful way. The care that you have for people comes across very well. What you share is always very practical, thorough, and more. Much appreciated!
  • Thank you. I'm new to your channel, and this piece on caffeine was very helpful. I have an appointment next week asking about low blood sugar or hypoglycemia that I'm learning about. My former Dr. Said this is a fluke and that my blood tests returned normal. But the office called me twice while was out and cautioned me that my levels were 33-I had been confused and was confused when they called. My pharmacist didnt want to alarm me be can fall into a coma :(. A nutritionist shed light on this. Maybe that is why I have so many headaches. I will see next week. But it looks like I may have to monitor blood sugar. Thanks.
