Stimulants and energizers are a category of supplements that are designed to enhance energy levels, promote alertness, and improve focus and mental clarity. These supplements are commonly used by individuals who need an extra boost of energy to stay awake and alert, such as athletes, students, and professionals with demanding schedules.

Stimulants in this category typically work by increasing the activity of the central nervous system, resulting in heightened alertness and a feeling of increased energy. They may also have effects on heart rate, blood pressure, and metabolism. Some common stimulants used in supplements include caffeine, guarana, and green tea extract.

Energizers, on the other hand, are supplements that aim to provide a sustained release of energy throughout the day. They often contain a combination of ingredients such as B-vitamins, amino acids, and herbal extracts that are believed to support energy production and combat fatigue.

Supplements in this category can come in various forms, including pills, capsules, powders, or drinks. It's important to note that while stimulants and energizers can be helpful for individuals looking to boost their energy levels, they should be used responsibly and in moderation. It's always recommended to consult with a healthcare professional before starting any new supplement regimen, especially if you have any pre-existing health conditions or are taking medications.
