Once oxidised, glutathione penetration is more challenging and also oxidised glutathione has less efficacy as compared to the reduced glutathione
Studies have shown that oral collagen can be absorbed at rates as high as 63%, compared to 1-2% for other oral peptides.12 13 Injectable collagen peptides are available, too, but surveys show a large proportion of the population would prefer a less invasive method.14 BPC-157 is another peptide that boasts good oral bioavailability, but the same cant be said about its frequent companion, TB4.15 16 Because we recommend BPC-157 and TB4 in combination, and because BPC-157 can be hard to find in oral form, BPC alone failed to earn our designation as the easiest-to-use peptide
Our bodies create their own free radicals, adding to the external free radicals that also besiege our bodies
