Pyruvate
Summary
Pyruvate is a glucose-breakdown product sold for weight loss. A 2014 meta-analysis of six weak trials found only 0.72 kg extra weight loss and called the evidence unconvincing; two training trials found no body-composition benefit, and one hinted at worse HDL. A 14-player sprint study reported more power after sodium pyruvate.
Key facts
- A three-carbon molecule formed when cells break down glucose; supplements are calcium or sodium salts[1]
- Meta-analysis of 6 RCTs: −0.72 kg vs placebo (95% CI −1.24 to −0.20); all trials had methodological weaknesses[1]
- 2 g/day for 4 weeks in soccer players and 10 g/day calcium pyruvate for 30 days in women in training did not change body composition[2][3]
- Gas, bloating, diarrhea and a rise in LDL cholesterol were reported[1]
- Calcium pyruvate may have blunted the HDL rise from exercise in one trial[3]

How it works
ProposedPyruvate links glycolysis to mitochondrial energy production. Supplement claims propose it raises fat burning; in the sprint study, sodium pyruvate raised blood pH and bicarbonate, suggesting a buffering effect partly from the sodium salt.[4]
What the human research says
Human trials only, one row per outcome. The form column shows what each trial actually tested. Grades follow our evidence-grading policy.
At a glance: strongest evidence per outcome
| Outcome | Grade | Effect | Strongest evidence | Rows |
|---|---|---|---|---|
| Weight | Grade D | No effect | RCT · n = 23 · 2005 | 2 rows |
| Exercise performance | Grade D | Improved | Crossover RCT · n = 14 · 2022 | 1 row |
Every graded row
| Outcome | Effect | Grade | Best evidence | PMID |
|---|---|---|---|---|
| Body composition and exercise capacity during training | No effect | Grade D | RCT · n = 23 · 2005 Untrained women starting a supervised exercise program Form: Calcium pyruvate · Dose: 5 g twice daily (10 g/day) · Duration: 30 days No significant change in body composition or exercise performance vs placebo; pyruvate may have blunted exercise-related HDL improvements. | 15797672 (opens PubMed)Source [3] |
| Body composition in trained men | No effect | Grade D | RCT · n = 22 · 2009 Young male soccer players Form: Pyruvate tablets · Dose: 2 g/day · Duration: 4 weeks No changes in weight, BMI, body fat, waist-to-hip ratio or muscle mass vs placebo; no side effects. | 20209468 (opens PubMed)Source [2] |
| Repeated-sprint power in soccer players | Improved | Grade D | Crossover RCT · n = 14 · 2022 Male college soccer players Form: Sodium pyruvate vs maltodextrin · Dose: Dose not stated in the abstract · Duration: 1 week per condition Peak and mean power over six sprints, phosphagen resynthesis and blood pH/bicarbonate were higher with sodium pyruvate than placebo. | 35249338 (opens PubMed)Source [4] |
Forms
| Form | Elemental % | Absorption (human data) | GI tolerance | Studied for |
|---|---|---|---|---|
| Calcium pyruvate | Varies[1][3] | No head-to-head human absorption data. | Gas, bloating and diarrhea reported at weight-loss doses; may raise LDL.[1][3] | Weight-loss and training studies (up to 10 g/day) |
| Sodium pyruvate | Varies[4] | No head-to-head human absorption data. | No adverse effects reported in the 1-week sprint study.[4] | Repeated-sprint performance (one study) |
Studied doses
Doses studied in human trials ranged from 2 g/day for 4 weeks (soccer players) to 10 g/day of calcium pyruvate for 30 days (women in training); weight-loss trials in the meta-analysis used various doses. The sprint study's dose is not given in its abstract.[2][3][1][4]
Interactions
Published interactions only: each row cites a source. No row means none was found in our sources, not that a combination is safe.
Who should be careful
- High cholesterol
- LDL increases were reported in weight-loss trials, and one training trial suggested smaller HDL gains.[1][3]
- Sensitive digestion
- Gas, bloating and diarrhea were reported.[1]
- Other medicines
- No interaction studies exist for anticoagulants, diabetes or blood-pressure drugs, antibiotics, levodopa or chemotherapy; the meta-analysis noted limited safety evidence overall.[1]
Talk to your pharmacist or clinician before starting a supplement, especially if you take prescription medicines.
How to read the label
Frequently asked questions
Does pyruvate help you lose weight?
Barely. A meta-analysis found 0.72 kg more weight loss than placebo across six weak trials and concluded the evidence was not convincing.[1]
Does pyruvate improve exercise performance?
One 14-person crossover study found more repeated-sprint power with sodium pyruvate; a 30-day trial with calcium pyruvate found no change in exercise capacity.[4][3]
What are the side effects of pyruvate?
Gas, bloating, diarrhea and a rise in LDL cholesterol were reported.[1]

What changed
- First draft. Every PMID checked against NCBI E-utilities esummary (title and year taken from the record) and abstracts read for the cited rows.
- Self-review pass (strict second read): meta-analysis kept out of the evidence table (no pooled participant count in abstract); 23-woman trial graded D rather than no-effect given its size. Drug interactions checked explicitly: statins (listed, LDL rise), anticoagulants, diabetes and blood-pressure drugs, antibiotics, levodopa and chemotherapy (no data, stated).
