Pyruvate (the buffered form of pyruvic acid) is a product created in the body during the metabolism of carbohydrates and protein.
Where is it found?
Pyruvate is formed in the body as a byproduct of the normal metabolism of carbohydrates and protein and is present in several foods, including red apples, cheese, dark beer, and red wine. Dietary supplements of pyruvate are also available.
Pyruvate has been used in connection with the following conditions (refer to the individual health concern for complete information):
| Science Rating | Health Concerns |
|---|---|
 | Weight loss and obesity |
 | Athletic performance (for exercise performance) |
 | Athletic performance (for improving body composition with strength training in untrained people only) |
| Reliable and relatively consistent scientific data showing a substantial health benefit. Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit. For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support and/or minimal health benefit. | |
Who is likely to be deficient?
Because it is not an essential nutrient, pyruvate is not associated with a deficiency state.
How much is usually taken?
Most human research with pyruvate and weight loss has used at least 30 grams per day. However, such large amounts may not be necessary. In a six-week double-blind trial, as little as 6 grams per day of pyruvate in combination with exercise, led to greater weight loss and loss of body fat, compared with a placebo plus exercise.1
Are there any side effects or interactions?
High intakes of pyruvate can trigger gastrointestinal upset, such as gas, bloating, and diarrhea. One preliminary study in exercising women found 10 grams per day of pyruvate reduced blood levels of HDL (the “good” cholesterol) after one month.2
