Effects of Caffeine Pills on the Body
Even if caffeine can be addictive, it is generally recognized as safe. It is naturally found in plants and added to products people regularly consume such as coffee, teas, chocolates, and soft drinks. Also, the caffeine market has introduced caffeine pills that have around 100 mg to 200 mg of caffeine per pill. You can buy caffeine powder capsules online.
How Caffeine Pills Work
Caffeine impacts the body in the same way whether you take caffeine from coffee or in pill form. The substance works by mimicking adenosine, which is a compound produced as a byproduct when the neurons fire when you are awake. A reduction in adenosine levels will make the body think it is getting ready to sleep. When caffeine’s effects kick in, you will feel the stimulation of your central nervous system. This is what provides you with an energy boost. The peak effects of the substance are felt around one hour after taking a pill.
A dose of 200mg to 400 mg per day is a standard dose for caffeine. But, the amount that is considered safe varies by person as caffeine is metabolized different according to one’s body composition and genetic background. Those who are planning to take caffeine as a daily supplement must consult with their doctor first.
What is Caffeine For
When you take caffeine, you will feel an increase in your heart rate and blood pressure. Such an effect can temporarily increase your mental alertness. That is why people who must stay awake for a long time take the substance. They include those who work at night, students, and scientists.
Some studies also found the benefit of caffeine for weight loss. This has to do with its ability to increase the resting metabolic rate and suppress appetite. Also, caffeine increases the level of adrenaline that signals the breakdown of fat tissue into energy. People who consume caffeine also feel a temporary boost in their athletic performance which is necessary to help them get through their workout.
Other Effects of Caffeine on Health
Caffeine also has effects on the following:
- Depression. Studies found this has to do with the ability of caffeine to increase the adrenaline level.
- Insulin resistance. Caffeine is found to help with insulin sensitivity which is a concern for people with diabetes.
- Alzheimer’s disease. Some studies show positive effects of caffeine on dementia. But, more research is needed to confirm this.
