IV Vitamin and Nutrient Therapy, also known as intravenous infusions, involves bypassing the digestive system by delivering essential vitamins and nutrients that are placed into a large bag of IV fluids and infused directly into the bloodstream through an IV placed in your vein
However, the half-life in the bloodstream is extremely short, so for optimal effects, very frequent administration is needed, and the efficacy is unproven
But the biggest risk was never the peptides themselves
Branched-chain amino acids, especially of leucine and valine, mediate the protein restricted response in a piglet model
A laboratory study showed silymarin inhibits a protein (MCT8 monocarboxylate transporter 8) that facilitates movement of thyroid hormones T3 and T4 across cell membranes, suggesting milk thistle might decrease thyroid hormone levels and the effectiveness of thyroid medication (Johannes, Endocrinology, 2016) [51]
