Whether or not you're an athlete or avid exerciser, adding hydration packets to your water can be a good idea. When you sweat, you lose water and electrolytes like sodium, magnesium, potassium, and others—all of which are essential to optimal hydration and body functioning.
"Hydration packets are envelopes that contain ingredients that help provide additional electrolytes and glucose to ultimately help people support their hydration status," said Lauren Manaker, registered dietician. "They can contain a combo of ingredients that provide nutrients like glucose, sodium, magnesium, potassium, and calcium."
When it comes to choosing the best hydration packet, Manaker recommends identifying your own specific needs. For example, in some situations, you may want more glucose, while others might call for more sodium. "Typically, a balance of glucose, sodium, potassium, magnesium, and phosphorus can offer some benefit for those who are trying to support their cellular hydration," she said.
Some come in the form of powders, while others are tablets that dissolve in water. And most are packaged in single-serving packets, which are easy to carry with you.
