Caffeine Supplements for Energy

Many supplements designed to increase energy and improve endurance contain caffeine. This natural substance is found in many plants, including tea and coffee, and it can also be manufactured in laboratories and factories. Caffeine is a stimulant, meaning that it increases the activity of the nervous system for short periods of time. As a result, many people use caffeine to help fight fatigue. Energy and endurance supplements that contain caffeine may provide only the stimulant or feature formulas that combine caffeine with nutrients that support the body during exercise. The amount of caffeine in supplements can vary and is listed in the dietary information. To compare energy supplements with caffeinated drinks, one cup of coffee usually contains 100 milligrams of caffeine.

What Are Electrolyte Supplements?

Perspiration is an expected part of exercise, as your body sweats to help prevent overheating during vigorous activities. As you sweat, your body loses water as well as salts called electrolytes. Without an adequate supply of electrolytes, your body cannot transmit nerve signals properly. This can lead to muscle weakness, feelings of fatigue and other unpleasant symptoms. Electrolyte supplements contain vital electrolytes like sodium, chloride, potassium and magnesium. When used after exercise, they may help to replenish minerals that were lost due to sweating.

Other Supplement Solutions for Your Fitness Needs

There are many different types of energy and endurance supplements available on the market today to help you perform at your best during exercise. Some products contain herbs that have been classified by scientists as adaptogens. There is some research to suggest that adaptogens like ginseng can help to reduce physical stress on the body, making them potential energy and endurance boosters. Other supplements contain ingredients like creatine and testosterone boosters believed by some researchers to help promote the development of muscle tissue. It's important to keep in mind that research into the use of various herbs and nutrients is still underway. In many cases, there is not enough evidence to know for sure that any particular dietary supplement is beneficial for all athletes.

Important Considerations When Selecting Supplements

Health care experts suggest that those considering energy and endurance supplements to complement their training regimens talk to physicians before using any type of product for the first time. Some supplements can cause side effects, interact with medications and complicate certain medical problems. A health care professional can help you to weigh the risks and benefits of the supplements available on the market, so that you can make an informed decision and select the best choice for your needs from the large selection here at drugstore.com.
