All that water, and still dry

The bottle is empty by ten, you've lost count of the restroom trips, and by noon your mouth is dry again, as if none of it landed.

A long flight makes it worse, with six hours of dry cabin air and two tiny cups of water. So does a hard session: the white lines on a dark shirt after it dries are salt you sweated out.

Water needs salt to stay

Your body uses sodium and potassium to balance fluid inside and outside your cells.† Plain water brings neither. It puts back the water and none of the salt you sweated out.

Researchers have measured this. In a 1995 study by Maughan and Leiper, six people who had sweated drank about 2 liters of drinks at four sodium levels, and the saltier the drink, the bigger the share their bodies kept.

  1. Sweat takes sodium out with the water, and plain water only puts the water back.
  2. Without that sodium, less of what you drink stays with you (Maughan and Leiper, 1995).
  3. Fuel puts back 600 mg of sodium plus potassium, magnesium and calcium, with ketones in the same packet, so the water you drink sticks around.†

Questions before you try it

How is this different from salt in my water?

You can salt your water. Fuel measures the sodium for you and adds 300 mg of potassium, 130 mg of magnesium and 290 mg of calcium, plus ketones (BHB) and C12, two non-sugar fuels your body can burn.† It's also Melonberry flavored, which a pinch of salt never is.

Why are there ketones in a hydration drink?

Fuel was made to cover both in one packet. BHB is a ketone: the fuel your body makes from fat when carbs run low.† We don't claim one packet puts you in ketosis. Nobody has measured that, and cutting carbs is what gets you there.

Has Fuel itself been tested?

Not as a product. The research on this page is about sodium, sweat and fluid, and it says nothing about our packet. What we did is put those minerals in a packet you can carry, with ketones alongside.

What does it taste like?

Melonberry flavored, sweetened with Glyvia™ and stevia. If you can't stand stevia, skip this one.

How much should I drink?

One packet in 12 to 16 oz of water, up to two packets a day, with plain water through the rest of the day. If you watch your sodium, take medication, or are pregnant or nursing, ask your doctor before you start.

What happens after the 3 packets?

After 14 days it turns into your monthly supply, and your 30-day supply arrives every month. Cancel anytime. Not for you? Cancel before day 14, pay nothing.
