Energy balance
Green Tea Extract (GTE) supplementation increases 24-hour energy expenditure and fat utilization in active individuals, but does not consistently improve sprint performance or antioxidant enzyme levels in trained sprinters.
If you are trying to manage body fat, Green Tea Extract (specifically with EGCG and caffeine) may help slightly increase your daily energy expenditure and fat burning. However, do not expect it to improve your sprint performance or replace proper training and diet.
ModerateQualifiesMEDIUM confidence
Dullo et al. [51] found that combination of green tea with caffeine (50 mg caffeine and 90 mg of Epigallo catechin Gallate for 3 times per day) increased significantly 24-h energy expenditure and fat utilization in active individuals.
Why this rating
Mixed results: positive for energy expenditure, negative for sprint performance and antioxidant enzymes in some studies.

- Caffeine supplementation (2-9 mg/kg) taken 1 hour prior to exercise significantly improves both endurance and anaerobic performance by stimulating the central nervous system and increasing serum catecholamines.Good
- Tribulus Terrestris supplementation does not improve muscle strength, body composition, or testosterone levels in trained individuals, despite marketing claims to the contrary.Good
- Ginseng supplementation (Panax ginseng or Siberian ginseng) improves cognitive performance, anaerobic performance, and endurance capacity in untrained or moderately trained individuals, primarily through antioxidant properties and central nervous system stimulation.Moderate
