Weight Management
To evaluate pyruvate supplementation on weight loss in obese women.
Study Type
Randomised, double-blind, placebo-controlled
Purpose
To evaluate pyruvate supplementation on weight loss in obese women.
Dose
22-44 g/day pyruvate
Participants
26 obese women
Duration
21 days
Results
Pyruvate supplementation produced significantly greater weight loss (-5.9 kg vs -3.9 kg) and fat loss compared to placebo when combined with a hypocaloric diet. Lean mass was better preserved.
How They Measured It
Body weight, fat mass (hydrodensitometry), waist circumference
To assess lower-dose pyruvate supplementation for fat loss without hypocaloric diet.
Study Type
Randomised, double-blind, placebo-controlled
Purpose
To assess lower-dose pyruvate supplementation for fat loss without hypocaloric diet.
Dose
6 g/day calcium pyruvate
Participants
23 overweight adults
Duration
30 days
Results
Lower-dose pyruvate (6 g/day) produced modest but significant fat reduction (-1.0 kg) versus placebo. Effects were less pronounced than high-dose studies, suggesting dose dependence.
How They Measured It
Body weight, fat mass, lean mass, metabolic rate
Exercise Performance
To evaluate pyruvate on endurance exercise capacity.
Study Type
Randomised, double-blind, placebo-controlled
Purpose
To evaluate pyruvate on endurance exercise capacity.
Dose
25 g/day pyruvate
Participants
15 trained cyclists
Duration
7 days
Results
Pyruvate supplementation significantly increased time to exhaustion (+20%) and improved endurance capacity compared to placebo. Muscle glycogen utilisation efficiency improved.
How They Measured It
Time to exhaustion, VO2 peak, submaximal endurance time
To assess pyruvate supplementation on arm exercise capacity and muscle metabolism.
Study Type
Randomised, double-blind, placebo-controlled
Purpose
To assess pyruvate supplementation on arm exercise capacity and muscle metabolism.
Dose
25 g/day pyruvate
Participants
10 healthy trained men
Duration
7 days
Results
Pyruvate supplementation significantly improved arm exercise endurance and was associated with greater muscle glucose uptake during exercise compared to placebo.
How They Measured It
Peak arm-cycling power, time to fatigue, muscle glycogen turnover
Fat Oxidation
To investigate pyruvate's effect on fat oxidation rate during caloric restriction.
Study Type
Randomised, double-blind, controlled
Purpose
To investigate pyruvate's effect on fat oxidation rate during caloric restriction.
Dose
22 g/day pyruvate
Participants
29 obese women on very-low-calorie diet
Duration
21 days
Results
Pyruvate supplementation significantly increased fat oxidation rate and reduced carbohydrate oxidation during caloric restriction. The shift toward greater fat utilisation contributed to preferential fat loss.
How They Measured It
Indirect calorimetry (RER), free fatty acid oxidation rate
To examine the mechanism of pyruvate's fat-reducing effects in diet-induced obesity.
Study Type
Animal study
Purpose
To examine the mechanism of pyruvate's fat-reducing effects in diet-induced obesity.
Dose
1% dietary pyruvate
Participants
High-fat diet fed C57Bl/6 mice
Duration
8 weeks
Results
Pyruvate supplementation reduced adipose tissue accumulation and increased UCP1 expression in brown adipose tissue. Mitochondrial uncoupling and enhanced fat oxidation were identified as key mechanisms.
How They Measured It
Body fat, adipokines, UCP1 expression, mitochondrial function in adipose tissue
Energy Metabolism
To describe the central role of pyruvate in cellular energy metabolism and TCA cycle entry.

Results
Pyruvate is the end-product of glycolysis and the primary substrate entering the TCA cycle. As a supplement, exogenous pyruvate may enhance mitochondrial substrate availability and shift cellular energy metabolism toward more efficient fat oxidation.
