Periflex PKU Formula & Oral Supplements

Managing phenylketonuria (PKU) means keeping blood phenylalanine levels in a safe range for life — and that depends on a dependable source of protein without the phenylalanine the body can't process. Periflex, made by Nutricia (Danone), is a line of phenylalanine-free medical foods formulated to supply the amino acids, vitamins, and minerals people with PKU still need at each stage of growth.

This collection covers the full age range families rely on. Periflex Early Years Infant Formula is an unflavored powder for birth to 12 months, designed as a complete first food when combined with a measured amount of breast milk or standard infant formula for tolerated phenylalanine. As children move past infancy, Periflex Junior Plus steps in — available in Berry, Orange, and Plain flavors in 400g / 14.1 oz cans — delivering a higher protein equivalent to match the demands of active, growing kids while keeping the amino acid profile phenylalanine-free.
