Redox Balance and Inflammation Regulation Liposomal glutathione improves cytokine balance, reducing chronic inflammation a root cause of aging [3]
Like Limonene, this ingredient oxidizes when exposed to air
(1996, Journal of Endocrinology) reported IGF-1 LR3 was 1.5-2x more potent than equimolar native IGF-1 for body weight gain, organ growth, and anti-catabolic effects when continuously infused in normal and dexamethasone-treated rats

It was originally isolated in 1977 from the cerebral venous blood of rabbits and has since been found to be present in small amounts in human brains and plasma, with higher concentrations later in the day.3 4 It, or a similar substance, is also present at higher concentrations in human breast milk.5 Because DSIP can cross the blood-brain barrier and is easily absorbed via the gut (unusual for a peptide), some researchers have hypothesized that it may facilitate post-feeding sleep tendencies among newborns, though it remains unclear whether DSIP truly has a hand in neonate sleep-wake cycles.4 5 6 Its mechanism of action is likewise unclear, but it may have something to do with endocrine regulation
