Key points

Nutramigen LGG Index Image

Combined logos

  • CMA is the most common childhood food allergy affecting 2–7.5% of infants1
  • Key clinical guidelines recommend extensively hydrolysed formula (eHF) as first-line management for formula-fed infants with mild-to-moderate CMA2–4
  • Nutramigen* LGG® has demonstrated short-term (symptom relief),5-7 medium-term (accelerated return to milk[A]),8,9 and long‑term (reduced future allergic manifestations10[B] and functional gastrointestinal disorders11[C]) benefits.

Product name

Nutramigen* 1, 2 & 3 LGG®


  • Nutramigen* LGG® is an eHF with LGG (probiotic) for dietary management of infants with CMA, providing age-adapted nutrition to support normal growth,12 symptom relief,5-7 and an accelerated return to milk vs other formula.9[A]

Feeding guide


Nutramigen* LGG®

Tins per month

0–6 months



6–12 months



≥1 year



See tin label for detailed feeding guidance; HCP to determine the formula intake based on the individual situation

Preparation and storage

  • Wash hands; clean feeding utensils in water (≥10 minutes rolling boil)
  • Boil fresh water; as soon as possible cool to room temperature; do not use softened water
  • Add powder and shake for at least a minute until completely dissolved
  • Feed immediately or cover and store in a refrigerator at 2–4°C for ≤24 hours
  • Store tin in a cool, dry place; after opening, keep tightly covered and use within 1 month.


  • Do not freeze prepared formula and do not use if unrefrigerated for >2 hours
  • Use formula that has been in contact with baby’s mouth within 1 hour and do not refrigerate
  • Do not heat prepared formula in a microwave.


  • Trial formula for up to 4 weeks to allow symptom recovery and formula acceptance2
  • To confirm diagnosis of non IgE mediated allergy, reintroduce milk and monitor whether symptoms return2[D]
  • Guidelines recommend eHF for formula-fed infants for up to 2 years or until allergy is outgrown13
  • ~50% of CMA infants remain allergic at 1 year of age with most reaching oral tolerance by the age of 3 years14
  • A ‘planned reintroduction’ by an HCP will determine whether tolerance to milk protein has been acquired.2[D]

About CMA

  • CMA is an adverse immune reaction to cow’s milk protein, presenting with immediate (IgE mediated) and/or delayed (non IgE mediated) symptoms4
  • Prevalence in infants is 2–7.5%1
  • Children with CMA have an increased risk of other allergic manifestations.10

Guideline recommendations

  • For formula-fed infants, expert guidelines recommend eHF for first-line management of mild-to-moderate CMA2,4
  • Hypoallergenic formulas (eHF and AAF) should be tolerated by 90% of children with CMA (with a 95% confidence interval). On average 10% of children with IgE-mediated CMA continue to react to an eHF. For those infants an AAF may be indicated.15

Evidence of use

  • Short-term: effective symptom relief:5-7
    • average clinical efficacy[E] of 99%3
  • Medium-term: faster oral tolerance acquisition:[A]
    • Approx 80% of infants return to milk after 12 months of use9
  • Long-term: reduction in future allergic manifestations:[B]
    • incidence of ≥1 other allergic manifestation (asthma, eczema, urticaria, rhinoconjunctivitis) reduced by ~50% as shown in Figure 1.10

Figure 1

Budgetary implications

  • Nutramigen* LGG® has been shown to be a cost-effective dietetic strategy, saving the NHS £497 over 3 years and £907 over 5 years per infant compared with an eHF alone.16[F]


  • Not recommended for premature and immunocompromised infants unless directed and supervised by an HCP
  • Babies fed eHF may produce frequent loose stools of a greenish colour (not unusual)
  • eHF tastes different to routine formulas but is well accepted by young infants.
