By the time those nutrients reach your bloodstream, you might only absorb 20-50% of what you paid for
and actually SARS-CoV-2 causing COVID-19, all are characterized by persistent inflammation, continuous production of reactive oxygen/nitrogen species and oxidative stress that predominate over the antioxidant defenses (GSH and free radical scavenger enzymes) resulting in cell/tissue/organ aging associated with early (premature) chronic inflammation/inflammaging. We propose that, although inflammaging was introduced for the aging process (276289), it could also apply to early (premature) tissue and organ aging associated with cell and tissue damage caused by excessive oxidative stress and lack of adequate antioxidant defenses, especially low GSH levels, in younger individuals
For peptide serums in particular, packaging can influence how well the active ingredients maintain their stability during storage and use
