Caffeine Tablets and Weight Loss

Losing weight is never easy. It requires changing your diet as well as adding fitness activities to your already hectic routine. You may be tempted to include caffeine tablets in your weight loss plans, but this can lead to harmful side effects. Always consult your doctor before making any major change to your diet or adding supplements such as caffeine tablets.


Amount of Caffeine in a Caffeine Tablet

The amount of caffeine in a tablet varies by brand. Most contain between 100 and 200 mg of caffeine. Some brands list the amount of caffeine each tablet contains on the label, but others do not. When in doubt, assume that caffeine tablets contain 200 mg of caffeine — you will not experience negative side effects from consuming 100 mg less caffeine than you expected, but taking 100 mg more than you anticipated could cause serious problems.

Caffeine and Weight Loss

Research regarding the relationship between caffeine and weight loss is inconclusive. It may help you lose weight. Some researchers have theorized that caffeine simply acts as a diuretic, so any weight loss is simply water weight. Others suggest that caffeine acts as an appetite suppressant or that it speeds up your metabolism causing you to burn calories faster.

Safe Amounts of Caffeine

According to guidelines published by the National Institutes of Health, 250 mg is a moderate daily amount of caffeine for adults. This is the equivalent of about 2 cups of coffee.

Other Sources of Caffeine

Caffeine is naturally present in over 60 plants, most notably coffee and Camellia sinensis, the plant from which tea is made. It is also used medicinally to treat migraine headaches and asthma. Many over-the-counter cold medications contain caffeine. If you decide to take caffeine tablets as part of a weight loss plan, be sure to keep track of the other ways that you consume caffeine. If you drink a cup or two of coffee in the morning, take a caffeine tablet with breakfast, consume a caffeinated soft drink in the afternoon and ingest caffeinated over-the-counter medication, you could easily double the recommended daily intake of caffeine.

Caffeine Toxicity

Too much caffeine can cause serious health problems. If you simply consume more caffeine than your body can tolerate, you may experience headaches, nausea and trembling. If you consume far more than the recommended amount, you risk inducing caffeine toxicity. At high levels, caffeine can cause vomiting, irregular heartbeat, confusion and hallucinations. In rare cases, caffeine toxicity can be lethal.
