Key gaps include limited protocol harmonisation, unrealistic exposure levels, scarce long-term/kinetic data, and insufficiently standardised, well-characterised PET MNPs preparations
Structure-dependent activity and preclinical and clinical studies are essential to elucidate its pharmacokinetic characteristics and bioavailability (115,116,120)
Second, there are biological risks
Growth hormone-releasing peptides improve delta sleep activity, which is linked to increased GH pulses and improved recovery outcomes. Van Cauter et al., Sleep 6
High mass balance values were obtained for all nanocarrier groups, which indicates the good recovery of the nanoparticles from the permeability samples (Table S3) and minimal sequestration in the cells or binding to the plastic surfaces of the culture-ware
Some research suggests that soil-based organisms and spore-forming probiotics like Bacillus coagulans may be better tolerated in SIBO than traditional Lactobacillus or Bifidobacterium strains, as theyre less likely to colonize the small intestine
