Strong Support

Taking sodium supplements while cycling for 3 hours in cool weather doesn’t stop your blood sodium from dropping slightly — and it’s no different than taking a fake pill. Nobody in either group had dangerously low sodium levels.

Sodium supplementation has no effect on endurance performance during a cycling time-trial in cool conditions: a randomised cross-over trial

Randomized Controlled Trial
Human
2013

The study gave cyclists salt pills or fake pills during a long ride in cool weather and found the salt didn’t keep their blood sodium levels more stable. This matches the claim.

Similar Assertions

Taking sodium supplements during a long bike ride in cool weather doesn’t really change your body’s sodium levels if you're already drinking fluids whenever you feel like it.

Taking 700 mg of sodium every hour during a long bike ride in cool weather doesn’t make well-trained cyclists finish faster — they perform about the same as those taking a fake pill.

If elite cyclists drink as much as they want during a 3-hour ride in cool weather, taking in 700 mg of sodium per hour helps keep their blood fluid levels stable—or even slightly increases them—while skipping it leads to a small drop.

If you drink a sports drink with 700 mg of sodium every hour while cycling 72 km in cool weather, your blood volume might go up a little bit because the salt pulls water into your bloodstream from your cells.

Taking sodium pills while cycling doesn't seem to make well-trained cyclists faster during a 72 km ride in cool weather — they finish just as quickly with or without it.
