Due to conflicting conclusions from numerous studies, the March of Dimes states that until more conclusive studies are done, pregnant women should limit caffeine intake to less than 200 mg per day. This is equal to about one 12 oz cup of coffee.
In respect to this, how much is 100mg of caffeine?
Up to 400 milligrams (mg) of caffeine a day appears to be safe for most healthy adults. That's roughly the amount of caffeine in four cups of brewed coffee, 10 cans of cola or two "energy shot" drinks.
How much is a lethal amount of caffeine?
The lethal dose for caffeine is in the neighborhood of 150 milligrams per kilogram of body weight (one kilogram equals roughly 2.2 pounds). While the average person's caffeine consumption is around 200 milligrams a day, the Mayo Clinic advises against exceeding 500 to 600 milligrams per day.

|Red Bull (8.2 oz)||80.0|
[It's also found in tea, hot chocolate and soda.] [If you drink] regular soda, 200 mg is roughly equivalent to five 12 oz cans. There are two mechanisms that have been hypothesized up to this point, linking caffeine to miscarriage.

One Journal of Analytical Toxicology report looked at nine different types of decaffeinated coffee and determined that all but one contained caffeine. The dose ranged from 8.6 mg to 13.9 mg. (A generic brewed cup of regular coffee typically contains between 95 and 200 mg, as a point of comparison.
250–300 mg of caffeine a day is a moderate amount. That is as much caffeine that is in three cups of coffee (8oz each cup). More than 750–1000 mg a day is a significant amount, but is very unlikely to kill someone. The Lethal Dose 50 of caffeine is 192 mg per kilogram, in rats.
However, when you get down to numbers the amount of caffeine is greater in a drip cup of coffee. One 2 oz double espresso shot has about 80 milligrams of caffeine. Whereas a 12 oz brewed coffee has about 120 milligrams. So actually there is more caffeine in an average cup of drip coffee than in espresso.
|Beverage (12 fl oz)||Caffeine (lab test)||Caffeine (manufacturer)|
|Diet Pepsi with Lime||36.4mg||37.5mg|
|Coca-Cola Black Cherry Vanilla||35.1mg||34.5mg|
|Diet Cherry Coke||35.0mg||34.5mg|
Bottom Line: The average caffeine content of an 8-oz, brewed cup of coffee is 95 mg. A single espresso or espresso-based drink contains 63 mg, and decaf coffee contains about 3 mg of caffeine (on average).
|Coffees||Serving Size||Caffeine (mg)|
|ávitāe Caffeine + Water||17 oz.||45-125|
|Mountain Dew Kick Start||16 oz.||90-92|

A can of Coca-Cola Classic has 32mg of caffeine and a can of Diet Coke contains 42mg. For pregnant women wanting a completely decaf option, we offer several caffeine-free drinks, including Caffeine Free Diet Coke, Oasis, Fanta, Lilt, Sprite and 5 Alive.
The average 12-ounce cup of decaf coffee – a Starbucks tall – usually contains between 3 and 18 milligrams of caffeine. (By comparison, an 8.4-ounce can of Red Bull contains 80 milligrams of caffeine) The average of amount of caffeine in regular coffee can vary significantly, usually between 140 and 300 mg.
Southern Sweet Tea contains 2.56 mgs of caffeine per fluid ounce (8.66mg/100 ml).
Women who consumed 200 milligrams or more of caffeine each day (about two cups of regular coffee or five 12-ounce cans of caffeinated soda) had twice the miscarriage risk as those who didn't have any, according to a new study by Kaiser Permanente in the American Journal of Obstetrics and Gynecology.
The results showed that the caffeine content of the decaffeinated espresso shots varied widely -- from 3 to nearly 16 milligrams; the caffeine content of the decaf brewed coffee ranged from 12 to 13.4 milligrams per 16-ounce serving.
A latte is simply steamed milk and at least 1 or multiple shots of espresso. We find that most coffee shops use a double espresso shot in a 16 fl.oz. latte while smaller sizes may only contain 1 shot for a total of 77mg of caffeine. If you aren't sure what your local coffee shop does, ask your barista.

How Much Caffeine Is in a Cup of Green Tea? The average amount of caffeine in an 8-oz (230-ml) serving of green tea is around 35 mg (5). However, this can vary. The actual amount can be anywhere between 30 and 50 mg per 8-oz serving.
It has come to our attention that Pepsi Cola has a different formulation in the UK and other markets and thus has a lower caffeine content there. It contains 37.6mg per 12 fluid ounce (355ml) can. It comes in many sizes and variations but most describe Pepsi as having a sweeter taste than Coke and they are correct.
We don't know a lot about the effects of caffeine during pregnancy on you and your baby. So it's best to limit the amount you get each day. If you're pregnant, limit caffeine to 200 milligrams each day. This is about the amount in 1½ 8-ounce cups of coffee or one 12-ounce cup of coffee.
Excessive caffeine consumption (defined as drinking three or more cups of coffee or tea daily during the first trimester) has been also associated with a higher incidence of miscarriage and low birth weight. Plus, as it does in adults, caffeine can increase a baby's heart rate.
