13 Popular Weight Loss Supplements - 7
12. Pyruvate
It is believed that pyruvate may aid weight loss efforts. One study showed that 22-44 grams per day of pyruvate enhanced weight loss and resulted in a greater reduction of body fat in overweight adults when combined with a low-fat diet.
Similar studies that employed 6-10 grams of pyruvate per day combined with an exercise program also lost weight. A few clinical studies suggest that pyruvate supplementation leads to weight loss by increasing the resting metabolic rate. However, pyruvate's effectiveness as weightloss supplement has not been substantiated.
13. Soy Protein
In October of 1999, the Food and Drug Administration (FDA) gave permission for companies to market soy protein supplements stating in their advertisements and on product packaging that soy protein may reduce the risk of heart disease. This is only the 11th time the FDA has allowed or endorsed a statement of this magnitude relating to a dietary supplement.
The actual health claim endorsed by the FDA states: Diets low in saturated fat and cholesterol that includes 25 grams of soy protein a day may reduce the risk of heart disease. In order to use this claim, soy protein manufactured must ensure their products contain at least 6.25 grams of soy protein and must not be high in saturated fat, cholesterol, or sodium.
