Andrew Huberman on Vitamin C — 96 claims
“I would not call vitamin C a cognitive enhancer per se, but deficiency definitely impairs cognition.”
Huberman does not consider vitamin C a cognitive enhancer, but states that vitamin C deficiency definitely impairs cognition.
None of the 20 studies listed directly address cognitive impairment due to vitamin C deficiency, nor do they evaluate vitamin C as a cognitive enhancer in the context Huberman describes. The closest r…
