The half life of caffeine determines how long the stimulant remains in the body. It varies from person to person, but it can take several hours for caffeine to be eliminated. That can be good or bad, depending on when you take it. If you have more than your usual dose late in the day, it can lead to a night of tossing, turning and no sleep.
It’s impossible to tell coffee’s exact half-life because it differs so much from person to person. A half-life is the time it takes for one-half of the amount of a substance to be eliminated from the body. For example, if you consume 200 mg of caffeine, the half-life is the amount of time until you have just 100 mg left in you.
Is it true caffeine makes you smarter? Sort of, it seems, at least indirectly. Researchers have studied this question a lot, and two groups of researchers did meta-studies (studies of studies) to determine just exactly what, if any, the conclusions of the scientific literature are.
If the title sounds like we’re hedging our bets, we are.
Whether caffeine makes you smarter is one question. Whether it makes you feel good is another. Test subjects in studies report they’re in a better mood after taking caffeine, they’re more alert and less fatigued.
Sublingual Viter Energy Mints deliver a quick kick to the bloodstream. One of the fastest ways to get a drug, vitamin or caffeine into the body is through sublingual administration—that is, under the tongue, where the substance dissolves and quickly gets absorbed into the body.
That is how Viter Energy Mints, our product, delivers a load of invigorating caffeine and B vitamins into the bloodstream quickly.
Recent news about caffeine, pregnancy and miscarriage is kind of confusing. A complex study from the National Institutes of Health and Ohio State University linked couple’s consumption of more than two caffeinated beverages a day to a risk of miscarriage. Just to be safe, women trying to conceive and pregnant women should limit caffeine intake.
Balancing sleep, caffeine and alcohol can be like walking the high wire. The National Sleep Foundation calls caffeine and alcohol “sleep stealers.” But studies show they are beneficial in moderate amounts.
6:38 a.m. That hour comes all too early, especially if people were drinking the night before. It’s the time when the average American awakens after an average night of 7 hours and 36 minutes of sleep. And the first thing most people do in the morning is brew a pot of coffee.
A 2015 study of more than 1.2 million people found that folks who drink 3 to 5 cups of black coffee a day have fewer heart problems than those who drink none. People who drink 5 or more cups don’t have any more problems than anyone else.
Two other studies, meta-analyses that collated data from 11 other research articles, found that drinking 2 to 6 cups a day results in a lower risk of stroke disease. One of those meta-studies included data from more than 500,000 participants.
We have good news for lovers of America’s two favorite mood-altering substances, caffeine and marijuana: Caffeine may enhance a pot smoker’s high.
The downside is that caffeine can also increase the chance of becoming addicted to cannabis.
The writer, Dan Charles, bought a 4-ounce bag of caffeine and said it had as much caffeine as 1,000 tall Starbucks lattes. He said this caffeine was created in coffee beans on a hillside in the tropics. “Slowly and quietly, driven by the energy of sunlight, it formed inside coffee beans hanging on thousands of trees, most likely in Brazil or Vietnam,” Charles wrote.
“Those beans were harvested, loaded on ships bound for the port of Houston, Texas, and ended up at a factory within sight of downtown Houston: Atlantic Coffee Solutions. It’s owned by one of the world’s largest coffee traders, ECOM Agroindustrial Corp., which is based in Switzerland.”
Sages and philosophers from various world traditions have counseled “Everything in moderation,” and, stated another way, “Nothing in excess.” These aphorisms apply to caffeine, too, because too much of this otherwise beneficial chemical can cause insomnia, nervousness, muscle tremors and stomach upset.
When people talk about having “a cup of coffee,” they don’t necessarily mean 8 ounces (236 milliliters). For example, many people go for the large size of coffee at McDonald’s restaurants and Starbucks, at 20 ounces (591 milliliters). Or at home, they may have a 12- to 16-ounce mug.
So when you read guides online that say an 8-ounce cup of drip java has about 163 mg of caffeine, you can more than double the amount of the stimulating chemical for a 20-ounce size. Drip coffee is the kind that drips through a filter to produce that cup or mug of the elixir that so many people say they can’t start their day without.
