While RUTF and RUSF treat malnutrition, LNS products are designed to help prevent malnutrition. LNS products are given to at-risk children ages six months to three years or to at-risk women during pregnancy and lactation. Medium Quantity LNS (MQLNS) is similar to RUSF in its composition, but the packets are half the size. The half-size (and roughly half-cost) of MQLNS makes it an affordable alternative for preventing malnutrition in both kids and moms.
