Rating (out of 5): 2

Potassium pyruvate is a salt of pyruvic acid and potassium, and it plays a role in cellular metabolism, particularly within the glycolytic pathway and the Krebs cycle, where pyruvate serves as a key intermediate in energy production. Some scientific studies have explored the use of pyruvate supplementation (including potassium pyruvate) for enhancing energy metabolism, improving exercise performance, or reducing fatigue. However, the evidence is limited and mixed.

Animal studies and some small clinical trials have suggested that pyruvate supplementation may enhance endurance and reduce perceived exertion, likely due to its involvement in ATP (adenosine triphosphate) production. A few human studies have examined its effects on exercise capacity and weight loss, with some reporting modest improvements in stamina or energy. However, these results are inconsistent, with several trials finding no significant benefit compared to placebo. Furthermore, most studies have used small sample sizes and varying doses, making it difficult to draw firm conclusions.

There is no strong, high-quality evidence supporting widespread use of potassium pyruvate specifically for treating general fatigue or energy deficiency in healthy individuals. The ingredient is not traditionally used for "energy" in folk medicine; its use is based primarily on its biochemical role in energy metabolism and preliminary research. Therefore, the evidence supporting potassium pyruvate for increasing energy is limited, meriting a score of 2 out of 5.
