When you're running low on energy, every part of your day can be negatively impacted. You may find it hard to concentrate, notice yourself drifting off and feel like every step you take is difficult. Over-the-counter medications can give you a quick energy boost to help you get through your daily routine. CVS carries a diverse assortment of OTC supplements for energy and alertness and makes it easy to compare and buy products online.
Most energy supplements use caffeine as their active ingredient. Caffeine is a natural chemical that is found in plants like coffee, tea and cacao. The caffeine found in supplements may be naturally derived or manufactured in the lab. When caffeine enters the body, it acts on the brain and nervous system, working as a energy booster. As a result, caffeine can provide a temporary energy boost and increase levels of alertness.
As you shop for energy and alertness supplements, it is important to consider their strengths. The strength of an energy supplement is determined by how much caffeine it contains, and this is measured in milligrams, abbreviated mg. Most products provide 100 to 200 milligrams of caffeine per single dose. For your reference, one 8-ounce cup of freshly brewed coffee contains 95 to 165 of caffeine, and one 8-ounce cup of black tea has about 25 to 48 milligrams of caffeine.
Another point of comparison between energy vitamins is their forms. For ease of use on the go, most energy and alertness products are pills. Tablets tend to be larger in size and slightly more economical, while capsules may be easier to swallow due to their shape and coating. You may also want to compare how many pills you receive in one bottle of each of the energy and alertness medications.
Although you can purchase over-the-counter energy supplements without a prescription, you should always consult your health care provider before trying any new drug. Caffeine does have the potential to cause side effects like jitteriness, shaking and rapid heartbeat and can trigger allergic reactions. As a result, medicines that contain the product are not ideal for everyone. To reduce your risk of side effects and ensure best results, use the product that you purchase according to the instructions provided by the manufacturer unless you are given other advice from your medical provider.
