TL;DR: Avoid high sodium, carbs, or sugar options unless necessary based on your exercise level or sweat test.
According to Amy Brownstein, a registered dietitian at MyNetDiary, electrolytes are essential minerals in the body, including magnesium, calcium, chloride, sodium, potassium, and phosphorus. These electrolytes play a crucial role in maintaining hydration by enhancing your body’s ability to absorb water.
Pediatrician Heather Gosnell emphasizes that sodium is critical for effective hydration. She also notes that small amounts of sugar and carbohydrates can aid in water absorption, but it’s best to avoid sugary drinks.
Electrolyte powders usually contain these minerals to facilitate absorption. But how do you determine the best powder for your needs?
Sherry Boles, RDN, explains that during exercise or exposure to heat, humans tend to lose sodium. Carbohydrates are essential for replenishing muscle glycogen stores to prevent fatigue, particularly for activities lasting over 30 minutes. If your exercise is intense and you’re not replacing lost carbohydrates, fatigue can set in quicker. To counteract this, carbs should be replenished every 30 to 45 minutes, with sugars like glucose playing a similar role.
If you’re seeking a supplement for everyday hydration or to alleviate a hangover, high levels of sodium or carbohydrates in electrolyte powder are unnecessary. Brownstein advises making choices that align with your daily eating habits. Most individuals already meet the recommended intake of 2,300 milligrams of sodium daily, so unless you’re significantly exercising, a low-sodium powder may suffice. The same principle applies to sugar.
Determining your specific needs can be achieved through a sweat test that analyzes your sweat’s composition. However, for non-medical needs, opt for a powder with moderate ingredient concentrations, except if you sweat heavily, train under high temperatures, or exercise at altitude—then, increasing sodium and sugar levels is advisable. Brownstein adds that if you notice white residue on your skin or clothes post-exercise, it might be time to boost your sodium intake.
Regarding synthetic dyes, Boles indicates the choice ultimately lies with personal preference. Thankfully, many recommended powders exclude these components to cater to your preferences.
To prevent stomach upset, Boles suggests selecting powders low in magnesium, as excessive amounts can have a laxative effect. Additionally, calcium and iron may hinder each other’s absorption, so opt for a powder with a balanced ratio. Brownstein advises checking labels to avoid supplement overdoses or excessive caffeine, as high sugar and sodium levels can irritate your stomach. For instance, if a product contains 100% of your daily zinc requirement, ensure you’re not concurrently taking a multivitamin with the same zinc content.
Boles recommends looking for powders rich in essential electrolytes, such as sodium, potassium, magnesium, and calcium, while steering clear of artificial sweeteners whenever possible.
Harry Zwibel, director of the New York Institute of Technology’s Center for Sports Medicine, warns, “Consuming sugary foods and drinks frequently may lead to gastrointestinal issues and decreased water absorption, as well as potential diabetes and weight gain.” He adds: “While electrolyte packets can help replenish minerals lost through sweat, they should not replace your daily fluid intake.”
