Your body is constantly using energy, even while you read this sentence! What about during the long duration of workdays and commutes? Professionals, students, and athletes need to sustain their physical and psychological alertness and mental focus, whether it’s prepping for an important presentation, the big game, or a major exam. Caffeine may improve focus and cognitive function.

Caffeine is the most widely consumed psychoactive substance in the world, and America is no exception. The American Medical Association estimates that about 85% of American adults consume 135 milligrams of caffeine daily. However, doctors recommend smaller, more frequent doses of caffeine than the average cup of coffee provides, such as 20–100 milligrams per serving.¹ Enter FreeYU Energy gummies, which contain 40 milligrams of caffeine per 2 gummy serving.

Stress is a significant issue for many Americans, with 53% of women and 45% of men experiencing frequent stress.² Many also experience physical symptoms including fatigue. Stress-induced fatigue can impair alertness and cognitive function; caffeine supplements may be a great solution.

Caffeine and Focus: A study published in Journal of Psychopharmacology found that caffeine enhanced performance on tasks requiring sustained attention. The study concluded that even low to moderate doses of caffeine (around 100–200 mg) could significantly improve concentration and focus for cognitive tasks.³

Caffeine and Cognitive Function: Research in the academic journal Neuropsychopharmacology suggests that caffeine can improve working memory and overall cognitive performance, especially when a person is tired or sleep deprived. This is why caffeine is commonly used during long work hours or study sessions.⁴

Caffeine and Mental Fatigue: A review article published in the academic journal Frontiers in Psychology explored how caffeine combats mental fatigue. It concluded that caffeine significantly improves mental performance in people experiencing fatigue from sleep deprivation or prolonged concentration.⁵

Vitamin C (ascorbic acid) is a potent antioxidant that helps protect brain cells from oxidative stress. It plays a crucial role in several brain functions, including the synthesis of neurotransmitters like dopamine and serotonin, which are involved in mood regulation and cognitive processes.

Effect on Mental Alertness: Vitamin C has been shown to reduce fatigue, improve mood, and enhance cognitive performance, especially in stressful situations. It helps reduce oxidative damage, which is particularly beneficial when the brain is under prolonged stress or mental exertion. Vitamin C can also support neurotransmitter function, contributing to better memory and cognitive focus.⁶

Benefits of the Combination of Caffeine and Vitamin C:

Enhanced Cognitive Performance: The cognitive-enhancing effects of caffeine combined with the neuroprotective effects of vitamin C can lead to better focus and improved performance on tasks that require sustained attention.⁶

Reduced Mental Fatigue: Vitamin C helps combat oxidative damage caused by prolonged mental effort, while caffeine helps to stay alert and engaged in tasks.⁶
