Oral administration results in lower systemic availability due to digestive enzymes, though the peptides stability allows local gastrointestinal effects at high concentrations which is why oral delivery is often preferred for BPC-157s gut healing applications
Generally, Asian ginseng seems to improve cognitive performance more than American ginseng, though the American form does still have cognitive enhancement potential.22 Korean red ginseng appears to improve concentration, scanning ability, and memory recall and is thought to stabilize the nervous system and decrease neuroinflammation.23 Ginseng also seems to be particularly potent when paired with ginkgo biloba, another nootropic botanical.24 However, a strict meta-analysis from 2010 could only identify five trials that met its stringent requirements for data reliability.102 Among those trials, there was a lack of convincing evidence to show a cognitive enhancing effect of Panax ginseng in healthy participants and no high-quality evidence about its efficacy in patients with dementia.
