Does Co-administration of Lactate to an Oral Glucose Tolerance Test Lower the Glucose Response?

Lactate in an OGTT (300 mL lactate drink = 25 g D/L-lactate bound to Na) =LAC with a stable isotope glucose tracer (D2-glucose) added to measure glucose.

Placebo in an OGTT (300 mL salt water, NaCl) =CTR with a stable isotope glucose tracer (D2-glucose) added to measure glucose.
