Proximal insulin receptor signaling and IR Insulin exerts its biological effects by binding to its cell-surface receptors, therby activating specific adapter proteins, such us the insulin receptor substrate (IRS) proteins (principally IRS1 and IRS2), Src-homology 2 (SH2) and protein-tyrosine phosphatase 1B (PTP1B), eventually promoting downstream insulin signaling involving glucose homeostasis
So, I'm talking to people now, and I'm saying, "Okay, why don't you think about changing the light bulbs in the home to just get that extra bit of red light to help you through?" We've got a trial for a retinal disease coming out shortly
Glutathione supports both Phase I and Phase II liver detoxification, with GSH conjugation constituting a major elimination pathway for drugs, metabolic waste products, and environmental toxins
How to implement: Dosing: 20-40 grams daily (post-workout or as snack) Choose undenatured whey (cold-processed, preserves bioactive peptides) Whey protein isolate (higher protein content, lower lactose) Best sources: Grass-fed whey isolate : Highest cysteine content Undenatured whey concentrate : Preserves immunoglobulins and glutathione precursors Avoid heat-treated : Heat denatures cysteine Timing: Post-workout (supports muscle recovery + glutathione synthesis) Morning (with breakfast) For vegans: Pea protein isolate : Lower in cysteine but can be paired with NAC Hemp protein : Moderate cysteine content Evidence: A randomized trial found that 20 grams of whey protein daily for 3 months increased lymphocyte glutathione by 35% and improved immune markers in HIV patients [15]

Our approach begins with thorough evaluationassessing your symptoms, reviewing relevant health history, and conducting appropriate laboratory testing to establish your current B12 status and identify any underlying absorption issues
