Acetyl-L-Carnitine HCL We selected acetyl-L-carnitine because it promotes brain health.* Its also involved in acetylcholine production, a neurotransmitter that plays a role in concentration.* Alpha-GPC There are many different types of acetylcholine precursors, but Alpha GPC has the most evidence supporting its efficacy and superior absorption through the gut wall and passage into the brain
Higher methionine concentrations increase production costs because raw pharmaceutical-grade methionine is expensive and 503B facilities must verify potency through third-party lab testing a fixed cost per batch distributed across fewer units at higher concentrations
It is not approved for people with insulin resistance alone, such as those with prediabetes or polycystic ovary syndrome
The mechanisms underlying these effects include modulation of the skin immune response by suppressing the production of inflammatory cytokines, such as interleukin (IL)-1 and tumor necrosis factor-alpha (TNF), and increasing the production of anti-inflammatory cytokines, such as IL-4 and IL-10, therefore promoting a favorable environment for tissue healing and reducing inflammation (Routley and Ashcroft, 2009
