Amino acids
Amino Acid Blend (Bi-Amino)
Also known as: bi-amino, tri-amino, BCAA, leucine isoleucine valine, arginine, glutamine, amino acids
Protein building blocks added to athletic and energy drips. Food usually supplies plenty; IV benefits for healthy people are unproven.

What it is
Amino acids are the building blocks of protein. Clinics often sell a named blend (Bi-Amino / Tri-Amino) plus standalone taurine and glycine. Other add-ons include arginine, glutamine, and the branched-chain amino acids (BCAAs: leucine, isoleucine, valine). NeuMed’s Bi-Amino label does not publish which three amino acids are in the vial — ask the clinic for this lot’s ingredients.
Why it’s used in IV therapy
Marketed for athletic recovery, muscle maintenance, and energy.
What the evidence says
IV amino acids are established medicine as part of total parenteral nutrition for patients who can’t eat. For healthy, well-fed people, sports-nutrition research consistently finds that total daily protein from food matters most — and oral protein or BCAAs are cheap and effective. There’s little evidence a small IV dose adds anything.
Side effects and cautions
Usually mild: nausea, flushing, or vein irritation. People with kidney or liver disease, or inherited amino acid disorders, should avoid them unless directed by a physician.
