Reference ranges
Optimal ranges are tighter than standard lab ranges and reflect functional-medicine targets, not the populations they were derived from. Reference bands depend on sex, age, and circumstance — Juno's lab analysis layers your profile context onto the printed range when you paste a value.
Peptide relevance
Sulfur-containing amino acid generated in methionine metabolism; elevated levels are an independent cardiovascular risk marker and a sensitive functional indicator of B12, folate, and B6 status. Treated by addressing the methylation cofactors (B12 methylcobalamin, methylfolate, B6) rather than directly. No direct peptide effects in common stacks. MTHFR polymorphisms (677TT homozygotes) often run higher and need methylated cofactors. NOTE: must be processed within 1h of draw — sample sitting at room temp falsely elevates due to RBC release. Order with the lab knowing this; many labs reject late samples.
Have a recent Homocysteine value?
Paste it on the lab analysis page. Juno reads your active stack + (if shared) your medications and conditions, and surfaces plausible contributors with citations. Doesn't diagnose.
