Way above my head but less of whatever isoleucine is doesn't sound advisable:

"Isoleucine participates in hemoglobin synthesis, as well as in the regulation of blood sugar and energy levels. Studies revealed that this amino acid has a very low toxicity at pharmatological levels up to 8% of solution concentration in rats."

"As a matter of fact, the three amino acids (Isoleucine, Leucine, and Valine) constitute nearly 70% of all the amino acids in the body's proteins. That is why their value in human body is so high."
