We buy the peptides themselves rather than the pre-diluted blend, so none of its carbomer, polysorbate 20, or butylene glycol comes along with them
Second, a spacer and C-18 fatty diacid chain are attached to lysine at position 26, enabling reversible binding to albumin in both subcutaneous tissue and circulation
Its regular formulation consists of: Milk Thistle Phospholipid Proprietary Blend: milk thistle integrated into a phospholipid complex, which bridges silymarins lipophilia and hydrophobia to improve absorption and bioavailability4 Siliphos: a branded milk thistle phytosome, which research suggests is better at moving into cells and reaching the bloodstream5 About Siliphos in Life Extension, the phosphates are carriers of silybin, believed to be the primary compound responsible for milk thistle's biological activity, particularly with regard to liver health.6 Here, the Siliphos provides 47.52mg of additional silybin, so the key takeaway (again) is that Life Extension delivers increased bioavailability of an important active compound
