In addition to this amino acid, there are other amino acids that promote collagen synthesis in the skin and joints: L-histidine, L-cysteine, L-glycine and L-proline
After 12 weeks, the researchers noted that the group receiving L-carnitine did indeed show improvements in fatigue, with the most significant improvements seen in brain fatigue. The most significant results were in those younger than 50, those over the age of 50 with high levels of free T3, and those who had hypothyroidism due to a thyroidectomy (who were taking relatively high doses of thyroid hormone)
Monitoring, Labs, and Outcome Tracking Baseline labs typically include serum B12, methylmalonic acid (MMA), and homocysteine
A qualified healthcare provider should evaluate your medical history, current medications, and biomarkers before recommending a stack versus tirzepatide alone
