We believe breast milk is the best food for infants. When in consultation with their healthcare professional, mothers and families find that optimal breastfeeding is not possible due to their infant’s medical condition, formulas for special medical purposes play a vital role in providing essential nutrients to infants. We have a global commitment to market breast-milk substitutes responsibly.

This website is about the management of cows’ milk protein allergy and nutritional solutions intended for infants. By continuing on this website, you accept that Nestlé Health Science supplies the information at your own request.

SMA® Althéra® will soon be the only extensively hydrolysed formula (eHF)* made using non-porcine enzymes and will better meet the needs of infants with cows' milk allergy (CMA) following halal, kosher or vegetarian diets1-2


eHFs traditionally use porcine (pig) pancreatic enzymes to hydrolyse protein and many caregivers may not consider this to be suitable for their child due to religious or cultural reasons. Our new clinical trial recipe tested in the clinical trial will no longer use porcine enzymes and will instead use a microbial and plant‐derived enzyme blend.2

The new innovative recipe has been tested in two clinical trials1,2 and has proven to be equally as effective in-vivo and in-vitro as the current SMA® Althéra® formulation for the dietary management of cows’ milk allergy.1 In another clinical trial, SMA® Althéra® demonstrated similar efficacy to an amino acid formula (Neocate LCP®).3,‡ 


We anticipate the new recipe to be made available from April 2020. All patients prescribing SMA® Althéra® at this time will be transferred to this new recipe. Please note, SMA® Althéra® will not be Halal or Kosher certified at launch, however the factory is applying for independent certification.

For the latest information on when independent certification is complete please visit nestlehealthscience.co.uk/cma-update


Research on the suitability of eHFs revealed significant differences in peptide composition, residual allergen content and sometimes batch-to-batch inconsistencies between eHF brands. “These differences in peptide composition and residual allergen content impact on the clinical efficacy and risk of allergic reactions to eHF”.2 Learn more here.

In the new clinical trial, SMA® Althéra’s® peptide and protein composition has therefore been published in full.1 You can read the full publication here.


* *SMA® Althéra® is not currently Halal or Kosher certified, however the factory is applying for independent certification. However the new recipe product will contain only Halal/Kosher ingredients and will be made with halal processing aids (e.g. using non-porcine enzymes for the protein hydrolysis process).

SMA® Althéra® is not recommended where only an Amino Acid formula is recommended.


Breastfeeding is best for babies. SMA® Althéra® and SMA® Alfamino® must only be used under strict medical supervision and after full consideration of the feeding options available, including breastfeeding. The advice of a doctor, midwife, health visitor, public health nurse, dietitian or pharmacist on the need for and proper method of use of infant milks and on all matters of infant feeding should be sought. Good maternal nutrition is important for the preparation and maintenance of breastfeeding. Introducing partial bottle-feeding may have a negative effect on breastfeeding and reversing a decision not to breastfeed is difficult. Social and financial implications should be considered when selecting a method of infant feeding. Infant milk should always be prepared and used as directed. Inappropriate foods or feeding methods, or improper use of infant formula, may present a health hazard.
