4. Improved Athletic Performance and Increase Hydration
Vegetable glycerin may help to boost your hydration levels. A higher level of hydration can improve your athletic performance. When a person becomes dehydrated it can impair their athletic performance. This is especially true when the loss of sweat is more than 2 percent of your overall body weight.
One good strategy to avoid becoming dehydrated is to make sure that you are drinking enough liquids both before you exercise and while you are exercising.
However, during some types of exercise, it can be impractical to drink. In these cases, it is important to make sure that you drink enough before you start working out. One issue with this is that drinking a large amount in a short amount of time results in it being lost through urine in an hour.
However, in one study it was found that adding 2.4 grams of glycerin for each pound of body weight to water before exercising can increase the retention of fluids by 50 percent when compared to plain water.
