What are the best electrolytes?

All electrolyte supplements that we sell are high quality, but two of the best electrolyte products are Catalyte and Daily Electrolytes, both from Thorne.

What are electrolytes?

Electrolytes are minerals that, when dissolved in fluid, are not bound to other elements and therefore carry an electrical charge. They exist in ionic form, meaning they can be either positively or negatively charged. This is exactly the form in which electrolytes are present in the human body.

In the body, electrolytes play an essential role in fundamental processes such as regulating fluid balance, transmitting nerve signals, muscle contraction, and maintaining the acid-base balance.

Electrolytes are found in blood, sweat, and other bodily fluids, among other places. The body tightly regulates their concentrations, because even small imbalances can affect physical functions.

Common electrolytes include sodium, potassium, calcium, magnesium, chloride, and phosphate.

When should you take electrolytes?

Electrolytes are best taken when the body loses fluids or needs extra mineral support.

Common moments include intense physical activity, heavy sweating, hot weather, or other fluid loss.

Electrolytes can also be useful during fasting, low-carb diets, or long periods of reduced food intake, when mineral intake may be lower.

For most people, electrolytes can be taken during or shortly after these situations to help restore fluid and mineral balance.

How much electrolytes do you need per day?

There is no single daily amount for electrolytes, because each electrolyte has its ownrecommended intake.

For healthy adults, daily needs are usually met through normal food intake and fluids.Extra electrolytes are mainly needed when losses increase, such as through sweating,illness, or heavy physical activity.

As a general reference, the body needs electrolytes in these approximate daily ranges:sodium in grams, potassium in grams, and magnesium and calcium in hundreds of milligrams.

The exact amount depends on factors such as diet, activity level, climate, and healthstatus.
