The Claim
Ingestion of a beverage containing 6% dextrin and 0.7% or 0.9% sodium chloride induces plasma volume expansion within 30 minutes in resting, euhydrated young men, with an earlier onset compared to sodium solution alone (which requires 60 minutes), indicating that carbohydrate co-ingestion accelerates the initiation of hypervolemia without altering the overall magnitude of expansion.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Drinking a sports-type drink with carbs and salt boosts blood volume faster than drinking salt water alone — it starts working in 30 minutes instead of 60, at least in healthy young guys just sitting around.
See the scientific wording
Ingesting a beverage containing 6% dextrin and 0.7% or 0.9% sodium chloride leads to plasma volume expansion within 30 minutes in resting, euhydrated young men, which is earlier than with sodium solution alone (which takes 60 minutes), suggesting that carbohydrate accelerates the onset of hypervolemia without increasing the overall magnitude of plasma volume expansion.
What the research says
1 studyThe study found that adding a type of sugar (dextrin) to a salty drink made blood volume go up faster, but not more overall, which is exactly what the claim says.
