Resistance-Trained Men Exercise Performance Study*

This study found that taking betaine for two weeks helped these resistance-trained men complete more repetitions during weightlifting, indicating slightly improved muscle endurance.* It also suggested that betaine might help muscles use oxygen better during exercise, possibly helping to reduce muscle fatigue.*

Distance Covered in 6-Minute Run Test Study*

This study found that taking β-alanine about an hour before running helped these athletes run a little farther during a short but intense test.* Both small and larger doses of β-alanine seemed to make a difference, but the higher dose didn’t show a big advantage, this means that β-alanine could be helpful for athletes looking to get a little extra out of their performance during tough workouts.*

US Navy Seal Training Cognitive Performance Study*

This study showed that taking caffeine helped the SEAL trainees stay more alert and perform better on mental tasks during extreme stress and lack of sleep.* A dose of 200 mg worked well for keeping them awake and focused, without causing jitteriness or other negative effects.*

Sprint Performance Study*

Taking caffeine helped participants run faster during short, intense sprints.* It made their muscles work harder but didn’t make them feel much more tired compared to when they didn’t take caffeine.*

Caffeine Alertness and Mood Study*

The study found that taking caffeine helped improve focus and alertness, especially with moderate doses (200 mg).* However, very high doses (400 mg) might make it harder to quickly change focus.* Caffeine also made people feel more awake and energetic.*
