This is because IGF-1 is made in the body
This is why you want to ensure you always get it in a highly absorbable form that helps stabilize and protect the glutathione
Methionine SAM (via MAT) methyl donor formation Homocysteine remethylation methionine (requires B12 ) Transsulfuration (CBS & CGL, needs B6 ) cysteine Cysteine + glutamate + glycine GSH (glutathione synthetase) Nutrient supports: B12, B6, folate for methylation & transsulfuration Sulfur-rich foods (garlic, onion, broccoli) Protein sources (eggs, fish, legumes) for amino acids Glutathione synthesis is the step-by-step process by which the body creates its master antioxidant to support detoxification, immunity, and cellular health
White Papers / Tech Papers Tackling Poor Bioavailability with Early Formulation Strategies De-risking oral clinical development with UpperSolv Released By Upperton High failure rates in clinical trials, estimated at up to 90%, remain a major hurdle in drug development, with poor ADME (Absorption, Distribution, Metabolism, and Excretion) properties being one of the leading causes of late-stage attrition
