06 L-Selenomethionine

L-Selenomethionine

Premium Selenium – Safest & Most Bioavailable

Ligand Features

L‑Selenomethionine (selenium substituting sulfur in methionine). The safest, most bioavailable selenium source – powerful antioxidant, targeted tissue deposition, and durable immune support.

Absorption Mechanism

Mechanism: The body cannot tell sulfur from selenium; L‑selenomethionine follows the methionine pathway. Unique Value: Nonspecifically incorporated into body proteins, creating a slow‑release tissue selenium pool for stress periods.

Efficient Absorption

Active uptake via methionine transporters – far beyond selenite's passive diffusion.

Targeted Deposition, Long‑Term Reserve

tRNA‑Met accepts Se‑Met as Met, building a sustained selenium reservoir in proteins.

Functional Benefits

Converts via transsulfuration to selenoproteins (GPx, TrxR) for powerful antioxidant defense.
