Low-dose naltrexone
Also known as LDN
Low-dose naltrexone is a medication or peptide considered in targeted protocols with clinician oversight.
Low-dose naltrexone is interpreted as part of a full biomarker pattern rather than in isolation. Trends over time and adjacent markers usually matter more than a single draw.
